SECTION I: The Artificial Technology Center™ with an AiHome™ What is the Artificial Technology Center?

The Artificial Technology Center (ATC) is to be a new and unique research and development laboratory. Its purpose is to advance and promote the technology of high-speed (Broadband) Internet applications. The center will advance the technology with an innovative research and development series of projects. It will promote the technology by demonstrating and educating the public as to the new possibilities offered by a broadband Internet (Bi). The ATC will use a constant flow of the latest PC and Audio/Video equipment and systems. The ATC will be built inside of a normal Executive Office Building with the construction of a partial house (approximately 1200sqft.) with easy to visualize Smart House wiring and the ability to use the ATC house called a AiHome™ as a retail store, a live development lab, and a classroom.

Why is it needed?

The Center is needed for one primary reason - to develop profitable systems for the Internet of tomorrow. All businessmen are aware of the difficulties in developing new products. Developing products for the Internet is even more challenging because no one knows how the Internet will grow and what it will grow into. We do know that its amazing technological advances have changed the rules of commerce, yet we do not yet know what those rules have changed into. Because of this, developing creative and profitable products is much more difficult on the Internet than in the past.

The Center will be an environment designed to quickly produce new products and technologies. It takes advantage of the fact that advances in broadband technology will soon turn the Internet into a high bandwidth network to the home.

These changes will open the door for a host of previously impossible applications. The Center solves the problem of how to create these different applications and it also determines if they will be profitable. It does this by building an environment where an Internet user can use the new applications in a meaningful and productive way, and where at the same time, we can assess their usefulness and profitability. The ATC’s environment is available online via the Bi and is called the AiDigital Library™.

SECTION II: The AiDigital Library™

What is the AiDigital Library?

The AiDigital Library is conceived as integration, both physically and in the abstract, of a library with the World Wide Web as it’s bookshelf. The goal is have an environment consisting of library and web, which fulfills the functions of both in the most useful and human centered manner possible.

We are building a library because a library, seen as a physical container of knowledge, has the same function as the Internet - today’s most successful and powerful container of Knowledge. The Internet has its enormity and timeliness of information, hyperlinks, plus the well-honed excellence of the various search engines The library, on the other hand, has the advantage of human comfort such as windows, chairs, desks, and space. Both however have the same function, which is to serve us humans in our ability to acquire, manipulate, and create information.

As the Center’s main tool for product development, the AiDigital Library will serve multiple roles as think tank, R&D facility, and technology showcase. By building it we hope not only to demonstrate the advanced capabilities offered by a high bandwidth Internet, but also to act as a bootstrap and catalytic agent for the development of commercially successful products.

The AiDigital Library will require innovative hardware and software I/O devices and solutions. The library must make one’s physical environment a powerful tool for accessing and manipulating the multitude of information streams present on the Internet: such as HDTV video, surround sound, hypertext search engines, and 3D visual data sets. Conversely, it must also allow one to control the physical Proprietary and confidential !

aspects of the library in such a way as to facilitate one’s control of the Internet and it’s multimedia. Solving these problems, and in general building the library, will result in the profitable Internet application’s needed for commercial success.

SECTION III: The Components

Overview The Artificial, Inc. “AiDigital Library” is a ongoing research and development project aimed at providing the user a multimedia digital library of all of their documents, photos, and home/corporate videos, as well as the using the internet as our Global Infobase.

How it’s done The computer selected is a SONY VAIO computer system with a Pentium IV, DVD, DV Firewire interface, Macintosh G4 DVDr system, VideoConference Camera, Color printer, Sony LCD flat panel screen, and a Digital Camera. The human interface is a local web site using our AI 3D-library QTVR look and feel; the user can operate everything in the room. From the rack of the Home Theater equipment in the AI 3D library, the user can access the any of the equipment using a connection to the AV control system, as well as cruise the internet, or retrieve and show documents, movies, and images.

Digital Library Hardware/Software Configuration Diagrams

These diagrams show the information flow through the hardware and software of the Digital Library. A software box is always inside a hardware box, so, for example, the Library Server is a large gray box containing the boxes naming the server software, the AIQuery Engine, the Crestron web software, and the web browser.

An arrow means a physical connection with the direction being either unidirectional such as with the audio/video signal going to the Wide Screen Monitor (red), or bi-directional such as with the Library Personal Computer Ethernet connection to the server (green).

One thing to notice is that in both diagrams the software AIServer box extends across the hardware box. This is done to signify that the server is indeed the server, such that all interactions between the Internet and any software that needs input or output must pass through it.

In addition, both the Portable Digital Library and the Digital Library are shown with independent hardware for the speech recognition. The portable one uses an interface card (which is why its box is inside the server box), while the Digital Library uses an external serial device (blue). This is done in order to reduce computational load on the server computer. Speech recognition is a real-time process so if the load is too great then recognition performance gets too poor.

However we may find a software-only package that avoids this. Using an external device also simplifies programming since the Digital Server then receives its speech as a serial ASCII stream.

The ST-COM, ST-I/O, ST-VC hardware boxes are modules need to do serial communication, bit I/O, and device control (e.g. receiver volume) respectively.

The Digital Library book is a display device with a touch screen used to manipulate web pages, and must be very simple and light. It does not by itself have any user input apart from that used in the touch screen. The main user control will be the touch screen with the display mirroring the server browser, and also the AI AudioResponse System (AiARS).

The position sensors used on both libraries are for are for virtual windowing.

too slow. Several infrared (non-invasive) systems are available. Another benefit is that if for some reason the Reality Fusion method is not workable then we can also use it to obtain the users position.

What will the library consist of?

The AiDigital Library will have a variety of software and hardware components.

They are named the following: The Physical Library The Library Web Site The Library Query Engine The Library Server Advanced Concept Tools The Physical Library The Physical Library is an actual library. The present one is located in Florida.

The library is comfortable, well lit, spacious, with computer access and a private collection of books, records, tapes etc. It also contains media players such as a multimedia capable computer, a HDTV capable large screen monitor, and a stereo system. Regardless as to how we construct the AiDigital Library, we will make sure it remains comfortable, spacious and well lit.

The AiDigital Library is not meant to be a replacement for a traditional library, nor for the creation of a ‘super’ high tech system with lots of bells and whistles.

These may be laudable goals but they miss the point of the AiDigital Library. The goal is to produce a melding of a library with its Internet counterpart. To do so successfully, we must maintain those qualities of a traditional library that makes it enjoyable and easy to use. These include in no small part those that make it comfortable, spacious, and well lit.

The Library Web Site As with the Physical Library, the Library Web Site (version alpha) is active (http:// www.ghklibrary.com/aidl). The Web Site will serve as the main conduit for the interactions between the user, the Internet, and the Physical Library. Its most important page is a well-done QuickTime VR rendition of the Physical Library.

This page will have controls and gateways to other control pages, which will allow the manipulation of the AiDigital Library. For example, if one double clicks on the image of the stereo system, then a new page comes up with information about the stereo system as well as controls to manipulate it. Likewise, if one double clicks on the image of the Wide Screen TV, information about your video database and controls become available.

Using a web site to control the library give certain advantages. We envision the AiDigital Library as containing a variety of different displays placed at various locations in it. Using the web in this fashion allows the user to control any number of library Internet devices with the same interface and on the different displays.

As such, the web site becomes a universal controller for the user.

The current Physical Library uses software from Crestron Home Control Systems (http://www.crestron.com/website/index.html) for controlling the home. This software will also be used for the control of the library from the web site. Its use will save us development time and assure compatibility with the house. Most importantly, the system is ideal for web hardware interfacing since it has been specifically designed for Internet control. In addition, it is a Java based system, which makes programming for the library much easier.

The Library Web Site user interface, although doable in Java, will require the use of Shockwave and Director. Shockwave was used for the construction of the current web site’s interface, and continuing do so allows for the use of previous work. Furthermore, Shockwave works with QuickTime VR graphics. Currently, QuickTime VR type graphics are an important part of the web site since the main control page is a QuickTime VR graphic. Many similar pages will be needed for the future development. Fortunately both Apple and Macromedia (http:// www.macromedia.com/shockwave/) have publicly available Software Development Kits (SDK). Apple released theirs years ago and Macromedia has just released theirs.

The Library Query Engine In a regular library a user is able to arrange his books, music etc. in whatever arrangement he desires (provided that it’s not the public library!). In addition, he can and probably will continuously add new material to his library. He could store these in any fashion he desires, perhaps even randomly. What he most likely will do is to arrange them in categories and store them in various locations such as shelves to help him find them in the future. Essentially, he wants space to store his materials and a method to find them whenever he wants to.

The Library Query Engine is the AiDigital Library’s method for selecting and storing Internet information that the user wants to select and store. In effect, it allows a user to do the same as he would in a regular library, however with all the types of information on the Internet.

As one can imagine, developing a query engine is not trivial because of the diversity of the media on the Internet and the complexity of categorizing the information.

A good example is the situation with photo and movie formats. There are many different forms of media and variations of them, such as the picture formats JPG GIF, TIFF, and the various movies formats MOV, AVI, MPG etc. A query engine must be sophisticated enough to decode all these formats and also learn about any new ones.

A much more difficult problem is how the query engine should categorize information in a manner pertinent to the user. Consider the example of a GIF image of a painting. One could categorize it by the colors, history, and even meaning. One analysis provides seven ways of making a suitable search engine (http://www.gils.net/showcase/). Some methods are very sophisticated and require the use of intelligent agents and/or content analysis.

Fortunately, there has been a large amount of government and industrial cooperation in the making of a universally accepted search engine (e.g., http:// www.dlib.org/projects.html). The result has been a concerted international effort to develop a world standard for searching for information. The standard is known as ISO 10163 in all places except the US, where it is more commonly know as ANSI Z39.50 does. This standard handles text information and also large complex collections such as found in libraries, universities, and museums (http:// www.gils.net/webz3950.html).

The US government has established the Global Information Locator Service (GILS) to assist in the development and dissemination of Z39.50 to the World Wide Web (http://www.gils.net/webz3950.html). The result has been the easy transfer of the standard to the commercial sector. Among other efforts, GILS makes available code samples and programming utilities for companies to implement search engines using Z39.50. One such company, Blue Angel Technology uses GILS to provide a large amount of the functionality required by Proprietary and confidential !

our engine (http://www.blueangeltech.com/). The AiDigital Library ‘s query engine could be made in conjunction with this or other such developers so as to save time and not duplicate efforts.

The Library Server In a regular library, the user has shelves in which to store his information. The Library Server will allow the user to do the same. However not just with text information as found in books, but with all different sorts of media. The Library Server will work in conjunction with the Query Engine to store multimedia and other information in the library. Furthermore, just as in a regular library where one never has enough shelves, the Library Server should have the most possible amount of disk space possible to hold all the information the user will store.

The Library Server must, just like the Query Engine, categorize and select information in an intelligent fashion. Think of what would happen otherwise. All of us who surf the web invariably save some information. Consequently, all of us who surf the web will most likely run out of disk space. What prevents this from occurring all the time is that we save only those bits of information meaningful to us? The Library Server needs to do the same thing.

In addition to selecting what to save, the Library Server must deal with the format in which to save it in. The PDF format from Adobe appears to be the best to use because PDF will be the most common interface output for the display panels.

We might have used Z39.50 since it makes use of a common internal data format. However on the World Wide Web, the .PDF format is increasingly Proprietary and confidential !

becoming the most favored method of storing documents that need to be accessed from a web site. In addition, there are a large number of skilled programmers available with expertise in the .PDF format.

SECTION IV: Advanced Concept Tools Advanced concept tools are possible candidates for commercialization: Each tool will be carefully examined as to its potential and feasibility. If acceptable, the concept will then be turned into a working prototype for use in the AiDigital Library. The library will be shown to the public and their reaction to the tool will be assessed. Based on this feedback and other more rigorous assessments (such Proprietary and confidential !

Artificial, Inc.

as is done in usability testing and human factors), the tool will either be rejected, or added permanently to the AiDigital Library and developed for the marketplace.

Building a tool is the most central part of the Library because it directly addresses the issue of profits. Building a tool uses all aspects of the Library. When ideas are proposed and critiqued, the library functions as a think tank. When a tool is built, the library functions as a rapid prototype and development lab. Finally, when the tool is demonstrated in the AiDigital Library, it acts as a marketing agency and a usability-testing laboratory.

A potential tool must be assessed very carefully and meet certain criteria to be successful. As previously mentioned, the AiDigital Library can be thought of as the integration of the Internet to one’s personal environment. It has as least two functions. First, it allows you to use one’s physical actions to work with the Internet. Secondly, it allows you to use the Internet to control one’s physical environment. The library should be comprised of tools that accomplish these functions. This is a loose criteria, but essential for maintaining the focus on the AiDigital Library.

Currently, most Internet users explore the Web with a browser on a PC. With the AiDigital Library, we want this capability and much more. The reason we want much more is because now, instead of accessing the Internet via one PC, we have an entire room that we can transform into tools for interacting with the Internet. Some of these tools will use the room features as control devices for manipulating the Internet. Others will serve to use the room as a large-scale addition to the web browser.

The following is a list with descriptions of tools that have been proposed as of 9/19/99: Tool: The Internet Book.

Description: A flat LCD panel display that allows control of the AiDigital Library Home Page anywhere in the Library. The device would be very flat, lightweight and rugged (encased in a cushion or leather padding). At the top left and right hand corners there would be large arrow buttons. These are used with the Forward Backward icons in the web browser.

The user goes to where he wants to in the library. Picks up the book and right away what he sees is the AiDigital Library page. As he manipulates the web site icons, appropriate responses occur in the various items in the real library. The interface is the web browser so that there is a little learning curve for the user.

Technically this is easy to implement. The quickest would be to use an industrial LCD panel with a long cable for connection to the network. If a cable is unwieldy we might want to go with a PC portable with an IR link to the net. Of course the IR link speed would not allow for the display to be used for video media, however that would not be its main use. The user would turn his head up and view the Proprietary and confidential !

movie on the wide screen monitor. The book would be mostly as a room/Internet controller and use only the local pages.

Tool: Visible Mouse Focus Description: Mouse Focus refers to the object that is currently selected by a mouse. In the real world we can also think about having a mouse focus that mimics the position of the mouse in the web site. This can be implemented in several ways. One is that as the user moves the cursor to a hot spot (e.g. the stereo), a spotlight focused on the real object lights up. Another possibility is by a servo-controlled light. This light would change its position as the mouse moves on the screen. This may be nicer because the moving light is a closer simile to a moving mouse than a spotlight turning on. There is also another function that this tool serves. We can also use it to let the browser select a book from your library.

If the browser knew your books and their location, it could point to a particular volume when the browser search engine hits include information found in your library books.

Tool: Reality Fusion Description: Without a doubt this can be a tremendous enhancement to the library. Using any common computer video camera, it allows you to use the subject’s position and posture to control things in the library. The company has a web site with a demo version that one can download. http://www.realityfusion.com It is very low cost, has a SDK, and being a local company, can perhaps be a valuable resource. Reality Fusion allows a tool called “User Focus”.

Tool: User Focus Description: This is an extension on the Visible Mouse Focus concept. We can think of the user as having a ‘mouse focus’ that we want the Internet browser to be aware of. For example, suppose that the user is choosing and adjusting his music system. Most likely, he will be standing next to the audio system so as to adjust the controls. The position next to the music system is a hot site just as the Web version location is a hot zone for double clicking. Knowing the hot zone can be very useful for modifying the equipment in preparation for its use. This is where Reality Fusion’s product is so helpful. We can use it to easily identify where the user is.

Tool: Voice Recognition Description: This is an obvious one and must be included. This tool is an example of a class of tools characterized by the fact that they are not marketable, yet still are needed for the Library. It is also a very important one because a poor implementation would be worse then none at all. People get enormously Proprietary and confidential !

frustrated at voice recognition systems that do not work. A careful choice of the many available must be made to avoid public dissatisfaction with the AiDigital Library as a whole Tool: Web Integrated Video Editor for Wide Screen TV Description: The wide screen TV offers lots of possibilities that will be looked at in another paper. Here, The tool gives is a non-linear editing capability for movies. It doesn’t have to be a complete set of controls, just sufficient to allow a user to stop, review, clip and save. A user could make small pieces of multimedia that serve as notes, study guides’ etc. For example, suppose the viewer just saw a news report about something pertinent to his job. The user should be able to freeze the video, select segments, and create a small video clip. The browser will serve to let the user manipulate the clips. For example, when the user wants to select clips to review, he selects their icons and drags them onto the Screen icon Tool: Virtual Headphones Description: As the user moves about, the library notes his location and moves the audio “sweet spot” so that it follows the user. We can use Reality Fusion technology to obtain the user’s position. The movement of the sweet spot is possible with PC sound cards that have 3D imaging capability, such as the SoundBlaster and Gravis cards.

Tool: Video Conferencing Description: Again an obvious one, not marketable, yet needed. To save development time, we will use an upper-end turnkey system offered to large corporations. The magazine AV Video has reviews of these. For public relations, we might want to get a well-known appropriate celebrity and have him be at the other end of the conversation during important demonstrations Tool: Keyed information Description: Keeping in mind the library metaphor, which connotes an ability to do research, we should offer some method of keying various parts of the multimedia stream. For example during video playback, the user should be able to mark the sequence (as previously described), but he should also be able to attach a text string used as a key for accessing information. The most natural way of doing this would use voice recognition. Envision a user looking at a news clip. He sees something of interest. Speaks “Stop”, “Rewind”, “Play for 10 seconds”, “Save Segment as Conference Example”. Resulting in a video clip saved to the server.

SECTION V: The Portable AiDigital Library The Portable AiDigital Library is an Advanced Concept Tool. It was not mentioned in the previous section because it merits a detailed description by itself. It will be the first tool to be built and the most complex to date.

The Portable AiDigital Library will be designed so as to allow a person to have as much functionality of the real AiDigital Library as possible. This tool is needed for a variety of reasons. In order to market successfully any product arising from the AiDigital Library, we have to take it to potential customers and tradeshows. The Portable AiDigital Library is designed for this purpose. In addition, because it is substantially different than the AiDigital Library (because of its size), it will most likely result in additional product concepts than the original.

The Portable AiDigital Library will have three separate LCD panels (not counting the PC display). Each one will be thin, lightweight and mounted on a swiveling armature, similar to that found in some light-stands. The display panels are mounted so that one can easily pick one up and reposition it by hand.

The displays have several features. They have touch screens. They have the Dimension-X overlay (http://www.dti3d.com) that allows 3D imaging. They have sensors that give the position of the screen with respect to the user.

The display panels form the basics of visualization dome’ that can be rearranged depending of the type of multimedia to be presented. Here is how we can use them:

Functions of the Portable AiDigital Library Panoramic images and movies: The user can put them side to side to form one large display. This can be used to show movies and images in the wide screen format.

Movie editing: One can place a movie clip on each display and use the third as a touch screen control for the editor. The editor could be a video-editing page on the library web site.

QuickTime VR viewing and control: If the user arranges them in a half-circle facing him, he would have an excellent viewer for QuickTime VR images. The displays arranged like this could give up to about a 120-degree wraparound screen. Viewing a QuickTime VR image, e.g. of the AiDigital Library web site would be impressive. The touch screens would allow the user to sweep his hand across the display and literally pull the graphics to where he wants.

GIS analysis: If you place a screen looking up and below you, it can act as 3D-terrain viewer for Geographic Information Systems (GIS). Its application could be in petrochemical 3D mapping and satellite analysis.

Flight, 3D, and game simulations: If you place the displays in a front, left, and right formation, they can be used for car and flight simulators. Used with a standard VRML plug-in, a browser (Cosmo is the typical one) can act as ‘spaceship’ that one can use to fly through the VRML space. This is done using the Dimension-X screen coating and the position sensors on the displays. The Dimension-X allows stereoscopic 3D displays without the encumbrance of glasses, and the position sensors allow virtual windowing.

Book and sheet music viewer: One could place 3 pages of a sheet of music or consecutive pages from a book.

As a sheet music viewer, we can use Reality Fusion technology so that the user can turn the page using physical motions.

Videoconferencing: If we add a video camera to each display, we would have a videophone capable of a conference with multiple views of the participants (maybe useful) or of anything that they put in front of the cameras (very useful).

Distance Learning: Proprietary and confidential !

Artificial, Inc.

Capturing live videos of lectures to a server will allow students in remote classrooms, distant cities and other far parts of the world the ability to attend classes at secondary schools, colleges and universities at their convenience.

The server allows not only distance learning but also 'time' learning, in the sense that they can view the lessons at a time of their choosing. This allows company employees working on undergraduate or graduate degrees, which must travel on company business or have to work during critical times, the ability to learn their lessons even while accomplishing their regular company business. Another market is in corporate training, military training or any other application where important information needs to be retrieved when the viewer has available time.

Tool: 3D-scanner station: If we add a video camera to each display, you could use it to produce real-time avatars of any object placed in front of the displays. Several companies make software that takes multiple view of an object, such as with pictures, and recreates it as a 3D volumetric model. What has not been produced is a real-time 3D volumetric model! This is not necessarily due to it being technically unfeasible, but rather because without some sort of multiple camera arraignment, there is no use for such software. The Portable AiDigital Library will have multiple cameras and so can make use of such software. One company makes a product that wraps a picture of a person in a smart manner so that it looks realistic.

However, it does this on a generic head model. A combination of this technology combined with real-time 3D volumetric rendering has great potential, and at the least would be impressive.

Networking: There is no reason apart from cost not to have the displays be addressable from the Internet. This would allow the useful feature of automatic configuration. A user could just put one of these things close to another, and they would sense each other's presence and configure the visual displays accordingly.

Section VI: Potential Business Associates This project will require a variety of technologies, and thus will also required business relationships with the companies that make those technologies. This is viewed as another benefit derived from the building of the AiDigital Library. Here we identify those businesses.

BroadBand Networks Corporation http://www.bbnc.com BroadBand Networks Corporation or BBNC is a company specializing in a variety of hardware for making broadband transmission possible, primarily for the cable industry. BBNC is a prime example of the company that the Center was designed to help. As such, we provide new product concepts and marketing by using their devices in the AiDigital Library.

Macromedia http://www.macromedia.com/shockwave/ Macromedia makes Shockwave, which allows multimedia like effects with on the web. It is well suited for use with QuickTime VR. They freely give out their SDK, which we will use.

Reality Fusion http://www.realityfusion.com/ Reality Fusion makes a computer video camera application that allows one to use the body space of the user for control of the computer. They supply a SDK and also a demo version of the software. This software is highly suited for the library because it makes use of the space around the user for control.

Cardiff Software http://www.cardiff.com/ Cardiff Software makes a product that allows one to create forms using the .PDF format. The library uses .PDF extensively, both for the display devices and also as the storage type for the library server. This product would be ideal for use on the library web site for this purpose. There seems to be no licensing difficulties except that they require a one-week training session.

SFS Software http://www.siteforum.com/ SFSS software has several products useful for the library. SiteEater, useful for the server, allows one to have local copies of web sites. InternalWeb creates a full text search index for any downloaded sites (via SiteEater). We most likely will need a developer's license because the products, as is, have their own interfaces that may be incompatible for our purposes.

Dimension Technologies Inc., (DTI) http://www.dti3d.com DTI makes a lenticular coating for LCD monitors that allow a user to view 3D without the use of glasses. This is important for the library because, although we want the user to view and use 3D content on the Internet, we do not want to constrict him in any way. He must be free to use the entire space available to him in the library.

Section VII: Tasks How do we begin? Building a sophisticated system such as the Digital and Portable AiDigital Library will require several major tasks. This section will look at the problem of construction and specify the various tasks needed to build it.

Some of these will be to build the hardware network backbone that will connect to the Internet and other broadband information channels to the library. Others will be for creating the software required both to connect the network to the Proprietary and confidential !

AiDigital Library, and also to build the Advance Concept Tools. A large task will be to devise or integrate a query engine into the Library. Another will be to develop the Library Server software. The server software will need to selectively select and store the information that will stream across the network. To start off with the first task will be the creating of the Library Server software.

The Server Software: Description: Task Description: Programmer Requirements: Section VIII: Other Issues Concerning the Oxygen Project This is a large (est. $10 million) project from the AI group at MIT whose purpose is to come up with the most integrated use of transmission technology - resulting in a variety of household objects that a person could query in a natural language context. In many ways this can be viewed as a generalized AiDigital Library.

However in this case the environment is expanded to include every possible space a human may interact in. This project is devised with technology projected to be available in about ten years. Obviously it is not pertinent to our effort in making commercially successful Internet products now. One thing that perhaps may be useful to us is their work on command language parsing. This might be available under a technology transfer program.

Profitability As designed, the AiDigital Library in itself has a limited market because of its cost. Some such markets are the government, petrochemical companies, and medical research groups. What it was designed for was to provide features that could be marketed independently of the AiDigital Library. What this means is that while we hope that the AiDigital Library by itself will be marketable; we expect that some Advance Concept Tools will be marketable.

Appendix A: White Paper Comments This document is the combined effort of a variety of people. The writer (Daniel Delgado) served as an editor of all the great ideas, which from all the people who contributed in some way or another. The creator of the concept of an AiDigital Library, its major designer and supporter, is Gordon Kraft. Chris King, also provided major input. As well as Ralph P. Manfredo of BroadBand Networks Corporation.

This document is our blueprint for the AiDigital Library, and also the conclusion of the serious discussions and careful thought processes that went into designing it.

As such, this document is also continuously in the process of being revised and expanded as new input and more decisions are made. This appendix lists various recommendations about the white paper for discussion. It is in an appendix because it is not intended to be seen except for those involved it its creation.

Section on Business Relationships: Proprietary and confidential !

Our connections to the various individual and companies are very important. It would help us to clarify who and why we need any such relationship. This has been implemented as Section VIII: Potential Business Associates.

Digital Presentation of the white paper: This document is intended to be as complete and detailed as possible so as to serve as the blueprint for the construction of the Center and the AiDigital Library.

Its detail makes it unsuitable as a marketing tool. We can resolve this by having a high-level digital presentation. It would be high-level so as to get the essential concepts across to our audience, yet not loose them in the detail. It would be digital because this would allow us the most possible audience. The presentation could be done as a PowerPoint demonstration, and/or as a well-done multimedia CD-ROM. Revision and editing by a professional technical writer: Without question, this document must be as clear and as well written as possible.

This document will be shown to potential business partners and investors. Its presentation must also be excellent for the same reason. It is important enough so as to let a professional technical writer edit and revise it.

Library research expert (digital): Considering the difficulties mentioned in building a universal library query engine, we should identify a partner or affiliation with that expertise. In addition to the benefits derived from a technology transfer, we could also use this for marketing and other support. Current candidates for such partners are those companies that build search engine type software (e.g. Blue Angel Technology: http:// www.blueangletech.com/). The other choice is an affiliation with a research group such as found in a university or government agency.

Internet use of Library for surveys and usability testing: Would it be feasible to give access to the basic library (free) in order to gain a large user email list - in exchange for surveys and usability testing? If yes, then levels should be created for whatever functionality is offered. There is where the profitability begins - at what level, at what point and at what cost? The library could represent the initial acceptance of the user and notify us that the library has become useful and important.

Top ten site access is needed: There are lists available that give you the top ten web sites visited on the Internet. These should be included in the basic library so se can be assured of user, market share. Each of the tops ten should be available in perhaps a richer and more useful environment.

MAST, Inc. It was a most profound experience for me intellectually; to have worked with a Artificial Intelligence company named MAST, Inc. Maui Analysis Synthesis & Technologies (M.A.S.T.) was a “Neural Network” software company, located in Kihei, Maui. MAST was founded by Mr. S. Warrick a naval architect, and very brilliant individual. Mr. Warrick, from the northeastern U.S., had moved to Maui partially because of the awesome wind surfing conditions present there. Soon thereafter, Mr. Warrick developed the sail design software that Mr. Kraft believes is still the hot ticket in wind surfing sail design.

MAST had another mainland guy named Mr. P. Billings, a mathematician from New Mexico. And a gifted computer programmer, part-time concert pianist, and a top Wind Surfer named Mr. J. Crim. They had developed a Neural Network program called NetCaster that attempted to “predict the S&P 500.”

DiagSoft, Inc. Mr. Kraft was the Founder, Chairman/CEO, and Chief Architect of DiagSoft’s PC Hardware QA Diagnostics business. At the time of the sale of DiagSoft we had bundled over 30,000,000 copies of QAPlus, and had over 85% of the worlds PC manufacturers testing their PC Systems with DiagSoft’s QAPlus Factory QA System.

Mr. Kraft opened DiagSoft’s Pacific Rim HQ just down the hall from MAST. And soon thereafter, Mr. C. King and Mr. Kraft founded a Multimedia company called “Big Kahuna Productions” in the Maui Research & Technology (MRTC) building.

Mr. Kraft purchased MAST thinking that the addition of Artificial Intelligence to DiagSoft’s QA products, and his new Electronic Technical Support Center (ETSC) project, and a multitude of other non DiagSoft computer implementations. On August 30, 1996, Mr. Kraft sold DiagSoft, Inc. to Sykes Enterprises in Tampa, Florida. Unfortunately MAST went with the sale. MAST was not supposed to be on the books of DiagSoft. Mr. Kraft had intended to move on with MAST after the sale of DiagSoft, and venture into the general Artificial Intelligence arena.

So without MAST to build on, Mr. Kraft founded Artificial, Inc. a Florida corporation. www.artificialinc.com Proprietary and confidential !

The Artificial, Inc. “AI Digital Library” is an Internet based multimedia virtual library that has the ability to interface with a Crestron Home Theater control system. Mr. Kraft began this project based on my previous expertise in Document Storage and Retrieval systems integration at Microform Data Systems in the 70’s, and my expertise in Office Automation Workstations and “Paperless Offices”. www.crestron.com (3). ! GHK Digital Library Mr. Kraft is an investor in the Dallas based, StarPower Home Entertainment, Inc. retail chain at the request of my friend, Nathan Morton, StarPower’s Chairman.

The initial implementation of the AI Digital Library was to create a multimedia library replicating a actual old English cherrywood library that Mr. Kraft have added to our home.

Summary The demand among individual users, home office users, and small business users for networking and communication solutions is increasing exponentially.

The growth in Internet usage and especially with DSL & Cable high speed digital access is fueling this demand, and the further increase in the number of multiple PC homes, and the limited number of networked small offices is adding to demand. Concurrently, there are numerous cable and USB product manufacturers as well as network hardware marketers offering partial solutions But none of these companies today are offering networking solutions that provide the user with auto installer capabilities of Moses NetAgent even when connecting a single PC such as the network connection of DSL. The installation of DSL is spotty and needs a much better approach in connecting the PC to the Internet, and installing the Ethernet adapter and 10BaseT networking hardware. With DSL, Moses has a way of integrating all the Ethernet system pieces by connecting through Moses DSL-Exchange. Moses software then installs and establishes communications for all devices. In doing the hardware and software, and the combination of both, Moses is the only solution provider offering the end users a complete solution to their networking and communications needs. With this advantage in the marketplace and Moses ability to successfully debut these products, and continue the introduction of new products, Moses will capture a significant portion of the growing high-speed access market.

Artificial, Inc. completes 97/98 Plan Gordon H. Kraft created Artificial, Inc., as an Internet based, Research and Development "virtual corporation". Artificial uses the full capability of the Internet to provide its customers with the most advanced Internet resources.

After an exhausting research effort into various Artificial Intelligence product areas(1), we concluded that the "Internet" offered the best long-term variant of Artificial Intelligence. (AI) from a profit generation basis, will provide the bestcase scenario for data mining the Internet.

We then began our initial development to create an "artificial world". As such, we have employed several high-end tools in the development of our sites with the intention to use these sites as the gateway for building the sites of the future. Tools like Shockwave, Real Video and Audio plus original animations and graphics mixed with live and taped media will propel artificial sites beyond the ordinary. Since the inception of Artificial Inc., we have pushed the content of our sites and our client sites to the maximum the Internet can provide. The following sites reflect our 97/98 R&D efforts:

This site utilizes Macromedia Flash and integrates all of our sites in an original graphical interface. We utilize Real Video Audio/Visual Video Streaming, and products like NetPodium for wide area business presentations, meetings, and CBT training. Artificial, Inc. elected Jeffrey O. Kraft as our new President in June 98. Jeff is responsible for the commercialization of our R&D efforts. www.ghklibrary.com The GHKlibrary is a state of the art, Apple QuickTime (QTVR/with hotspots) replication of a real SoHo library. It's purpose is for building future custom internet based Home Digital Library's (HDL)(2), This site is our initial effort to develop a next generation "what you see is what you get, even if your not at home". And provides its user unparalleled information search and retrieval from the Internet's vast InfoBase. Unlike desktop routines, which are merely a navigation aid, the GHKlibrary is a web based resource center from which the user can manipulate both desktop applications and the Internet for a truly integrated desktop management tool. While this version of the Library may never see the light of day as a commercial product, it does show how technology can be combined into one format. Prior to releasing the Library as a commercial product, several key security and product issues must be resolved.

The Library was created for the sole purpose of uniting the Internet with the desktop. As anyone knows who has accumulated file upon file of information, it has become increasingly impossible to catalog this data for future reference.

The Library, by use of third party applications, will bring this under control.

The real GHKlibrary has a complete Computer Research Lab for creating and testing of integrated leading Internet technologies(3).

Think of it as a huge desk drawer that the user dumps everything that they come into contact with. This includes BetaSP/SVHS/Hi8/DVcam Home Video, CD Library, DVD Library, Star Power Home Theater(4), and includes a complete multimedia Video Editing Suite, as well as Textual and Graphical info in a multitude of data formats including: MS Word, MS Excel, MS PowerPoint, MS Outlook, Adobe PDF library, MPEG/ JPEG/GIF/PhotoShop library A IBM Infinity 5500 with dual Pentium II 400 NT Video Server for the home, with over 100GB of hard disk, and DAT backup running an automated home over 100T cat 5 LAN.

Portable Library Specifications These specifications are for the Portable Digital Library, which is being built as the main showcase for the Artificial Technical Center. Both the Center and the Library are explained in detail in the white paper "The Artificial Technology Center and the Digital Library", available on the Artificial Technology web site: http://www.ghklibrary.com/aidl/ This document is for the purpose of describing how to build the Portable Library.

It is comprised of three sections. The first section, Methods, describes the desired features and then procedures for making them. The second section, Materials, is a list of items to be purchased. The third section, Notes, contains information pertinent to the library as a whole. In addition, a schematic overview of the library's hardware and software components is shown in Figure 1.

Methods Feature: Moveable Display Screens Description: The ability of a user to place the displays in almost any position or orientation desired. This is a fundamental component of the Portable Library.

The Portable Library has three main LCD panels for its displays. By positioning the displays in various configurations, the user of the Portable Library can use it as either a wide screen system, or a wraparound QTVR viewer, or an out-thewindow views such as is used for flight and car simulators (these configurations are described separately as individual features). In addition it also allows the user to use the entire space around him for the Windows Desktop. With this a user can, for example, place file icons for movies clips above his head, and sound clips next to his left ear.

Procedure: Modifying a "Magnifier Reading" lamp provides the mechanical arm that supports the Library's displays: http://www.hammacher.com/DefaultPage/default.asp?ContentPage=/publish/ 67468.htm These lamps have a large magnifying lens and are used by people who do precision miniature work as well as by the sight impaired. Because of their needs the mechanical support linkage has been optimized for maintaining the light and lens at a position of the viewer's choice. This is the capability the library needs for its displays.

Three lamps are needed. Each is modified so as to remove the head/light assembly and substitute it with a LCD display. Depending on the weight of the lamp, we may also replace various springs for ones of higher tension to compensate for the greater weight of the display.

To obtain the display's location and orientation in real-time, we use imageprocessing software provided by Reality Fusion: http://www.realityfusion.com/ described in the Materials section. Each display monitors the position of the others so as to provide a continuous feedback as to its position and orientation.

Written with Reality Fusion's SDK, a program on the Portable Library calculates the display position with respect to the user, and then provides the information to other parts of the library. The library can then access the information in one of two ways; either by using Window event messages or by using a shared memory location. The conventional method is to use Window event messages. However, it this is not feasible we will resort to a shared memory location. In either case, any program that requires positional information, such as a Java Applet activated from the browser, must make use of the tracker's SDK if it needs to access this information.

For the out the window simulators, the program will change the display mode to one viewport per display. The different views can then be produce by either configuring the software for this arraignment or by running multiple instances of the executable, but with different viewing positions (e.g. left, right, and front views).

For the QTVR and Panoramic viewer, the program will change the display mode to one large viewport with each display mapping into a different portion of the view. This configuration will also be used to enlarge the Desktop to surround the user.

Feature: QTVR Viewer Description: The QTVR Viewer is a configuration of the library that is optimized for the wraparound images of QuickTime VR. The LCD panels are positioned side-bye-side in a semicircle. Such an arrangement can increase the field of view (FOV) to as much as 120 degrees. The aim is to give an experience similar to that of a 'Circle-rama' theater such as is found in Disney Land. Since QTVR images are used extensively by the library, this will be an important part of the overall effect of the Portable Library.

Procedure: A program will be written that monitors the position of the three displays. When the user places them side by side in a semi-circle, the program will send a Windows event message to all active programs, and also change the display mode to that of one large viewport with each display mapping into a different portion of the view. In addition, the size and aspect ratio of each viewport will be changed to match the FOV of the combined monitors and a system message will be added that reminds the user to reposition the displays when viewing a QTVR image.

Feature: 3D Display Description: The use of the Dimension Technologies lenticular coating allows a user to see volumetric 3D data without any encumbrances such as goggles or LCD shutter glasses: http://www.dti3d.com/ With it the user will be able to explore 3D data sets on the Internet using a VRML browser. He will also use it with car and flight type simulations and for watching 3D movies Procedure: The displays must be very lightweight LCD panels. To use the Dimension Technologies 3D coating, we must use a LCD panel display because the effect depends on the characteristic of liquid crystals to polarize light. To use the display for the Portable Library, we must also make the displays as lightweight as possible. Weight is an important factor because the Library's support arms are optimized for the weight of its lamp and lens assembly. Our displays must be the same weight or lighter.

We will require three displays. They will be bought off-the-shelf, or adapted from laptop displays, or built by us. The most convenient way would be to purchase them, however it is unlikely that we will find off-the-shelf displays that meets our needs. The next easiest solution is to buy a portable computer and remove its display, power supply and video circuit board. This may be made more convenient by finding a manufacturer that will sell us just the video components from its laptop. Regardless, we then substitute long cable assemblies and put only the LCD panel on the arm, all else will be placed at the base of the arm.

If obtaining a manufactured display is not possible, we will buy a LCD panel, a video interface board, power supply, and build it. This is not very difficult but is a more involved process than the other methods. On the other hand this way does give us the advantage of allowing us to select the best and most appropriate parts.

After obtaining the displays, we then send them to Dimension Technologies for them to apply the lenticular coating need for 3D. Since this may take some time (not under our control) we will send the displays to the manufacturer as soon as possible. Development will then continue using a standard monitor display. To speed development, an effective yet costly way would be to obtain an off-theshelf 3D monitor from Dimension Technologies in addition to the coatings for the library's three displays. The 3D monitor can then be used for development until the library's displays are modified.

Since VRML 3D models are the most common types of 3D objects found on the web, we will have a VRML browser with 3D capability. The Windows web browser Explorer calls its own VRML browser, but others are easily substituted.

Hopefully, the Dimension Technologies people know or sell a web browser with built-in 3D support. Otherwise, we will use a well-known VRML browser such as Cosmo Player and adapt it for use in the Library.

Many simulator games now support 3D viewing. The Portable Library will be able to work with all such games and programs. These are meant to be use with LCD 'Flicker' glasses. The lens go dark then light, only allowing one eye to see an image at any one time, usually at a rate of the display monitor synch (e.g. 60 hertz). By presenting to each eye one image of a stereoscopic pair, a fairly effective 3D effect is produced. The Portable Library's 3D coating is compatible with this method. We should verify this with MS Flight Simulator and a popular network flight simulator, and some other popular programs.

Feature: Panoramic Viewer Description: The displays are placed side by side for viewing videos with wide aspect ratios such as Panoramic movies. Unlike the QTVR displays, the images are not arranged in a semi-circle but as one large flat display.

Procedure: Although this is a simple concept, achieving a workable view will be difficult. When watching movies and looking at images, one should not have a border along each portion of the image mapped by a display. Yet just about all displays have a border along all edges of the display, somewhat like a picture frame (in the case of a LCD panel, this is probably the display circuit board). The ideal solution is to find a display with no borders at least along one dimension.

Without this, we may be able to achieve the same effect with real-time optical correction and some type of mirror arrangement. Please see the Addendum: Concerning making a flat display with no gaps (Gordon, I think we might have some patents here).

Regardless of how it is achieved, speech, hand motion, and the touch screen will control the Panoramic Viewer. As with the QTVR viewer, it will make use of the IR position sensors on the library's three display support arms. A program will be written that changes the display mode to that of one large viewport with each display mapping into a different portion of the view. Again as with the QTVR viewer, the size and aspect ratio of each viewport will be changed to match the FOV of the combined monitors, and a system message will be added that reminds the user to reposition the displays when he is viewing a QTVR image.

A user will be able to use the Panoramic Viewer for editing and interacting with video (such as is done with enhanced DVD's). While watching a news clip the user could say "stop" followed by "save as example one", which would result in a of a clip of video saved onto the hard drive. He could also use hand motions or the touch screen to change the speed of the clip. The user will also be able to manipulate static images. He will be able save an image to disk by using his Proprietary and confidential !

finger to trace around a frozen video segment (such as with a mouse with MS Photo Editor).

Feature: A Friendly Librarian Description: The user can easily search both the Library's material and the Internet without the user needing to know browser commands. It then presents the material in a manner appropriate to the media, so for example video is sent to the Wide Screen TV and audio is channeled to the music system.

Procedure: This is a very challenging feature. It must make use of the software routines of every SDK used in the library. Software must be written to allow control with voice, hand gestures, touch screen and keyboard entry. With voice the user will be able to address the librarian, ask a question, and have packaged "power-point" type presentation of the information. The initial version will try to simplify the problems by limiting the information and media to that obtained from the Internet via the web site of Margaret Anderson: http://www.servtech.com/~mvail/home.html.

This allows the program that is parsing the information to make use of a common data format. A Java/C++ programmer will be used.

Even using Margaret's web site as a test site, various programs must be written and integrated together. First a control program that monitors all I/O, meaning keyboard, voice, gesture, and desktop commands. Upon activation by the command 'Librarian', which e.g. is done by voice by calling out "Librarian", the program must parse the subject's question, and then output one or more browser commands to obtain the information. Having received it, the program must then select the appropriate medium and present the information. The difficulty lies of course in programming the presentation.

Feature: Hand Motion Control Description: The user can control various aspects of the Library hand by using hand gestures. These are the following: QTVR viewer Video Photographic images Music Hopefully this will be one of the more natural ways for controlling the library. With this a person could sweep his hands across a QuickTime VR image and have it rotate around him. He could point to a display icon and launch it by literally making a throwing motion or other such gesture. With photos or other graphics, Proprietary and confidential !

a user can use his hands to pan an image larger then the viewport. For video, the user can use gestures for the editing commands such as stop, fast forward, and reverse. For music, the user can interact with any of the numerous programs available for creating, conducting and playing music. For example, a user could do such things as change tempo, switch or add instruments, change the rhythm or 'turn' a page while one plays.

Procedure: Software from Reality Fusion will be used for recognizing gestures.

This software does a real-time analysis of the video input so as to respond to specific hand and body gestures by the user. To use it a small lightweight video camera facing the user will be attached to each display panel. Using the Software Developer's Kit (SDK) that has been provided by Reality Fusion, we will write software to interface it with the Library. The software will send the appropriate user I/O (most likely emulating ASCII from the keyboard) when it senses a command gesture. Reality Fusion will be used for the following: QuickTime VR Viewer Melody Assistant (shareware) Microsoft Photo Editor (GIF, JPG and others) QuickTime Viewer (MOV) Microsoft Active Player (MPG) Feature: Speech Control Description: The user controls various functions of the Library by voice. Voice commands will be used for the following: Windows Commands Web browser Library web pages Display settings (brightness, aspect ratio, contrast etc) Video (editing, stop, start, rewind etc.)

Music (loudness, bass, treble etc) Procedure: The software ViaVoice will be used for speech control. Like most voice recognition systems, it comes with a command set for controlling Windows (such as with file commands) and also procedures for setting up command sets for programs. With this we can then give the user control over the display settings since they are adjustable by the operating system. Command sets will be written for the other functions.

The first command set will be written for the browser since it will be the primary user interface. By doing so we add voice commands to the Library's web pages.

To add voice capability for video, music and the display mode, additional command sets will be set up for the most commonly used video and music editor programs, as well as for changing the display. The programs that will have command sets written are the following: Proprietary and confidential !

Additional command sets will also be written for the audio player and other multimedia programs that were provided with to the computer when purchased.

For show demonstrations we need to make sure we can use voice independent commands for at least a subset of those needed. If ViaVoice does not supply this than we obtain an additional software package that does to be used in conjunction with ViaVoice.

Feature: Touch Screen Control Description: The user can control the Library using touch screens on its three displays. Using the software typically supplied with the screens, the user will be able to select icons, move scroll bars, etc. just as if done by a mouse.

Procedure: The touch screen will use an active optical matrix keypad and interface with the Library computer through the serial port. Tentatively, we will use a display from Intersense Inc. http://www.isense.com This works by placing optical infrared emitter/transmitters around the perimeter of the display. Unlike the pressure sensitive kind, they do not obscure the image.

We will also have fewer problems with vibration because they do not require an actual press on the screen. This particular touch screen needs to be tested to see if it does not interfere with the IR from the head tracker. We may have to use the pressure sensitive kind if the other's infrared system interferes with the tracking system that is used for display and other positional information.

Touch screens typically come with software so that a user can control the screen as if it were a mouse. We will use this for most of the functions in the library that will make use of the touch screen (those that are mouse like). If the library is using the displays in a group (such as with QTVR), the touch screen will be active across all three screens and with one shared viewport.

Feature: Three-Camera Viewport.

Description: Each of the three LCD displays has a lightweight video camera attached to it. Used with a good user interface this feature could be one of the more marketable aspects of the library. They provide the benefit of three viewpoints of the participants in conference. In addition, because a user of the Proprietary and confidential !

Portable Library can reposition the displays and cameras, they can move them so as to interact with other participants.

We could greatly enhance the effectiveness of this type of videoconferencing by designing utilities that help the user use the three-viewport arrangement. These could include such things as a 3D global display of all participant's in one picture, or as a tactile response when remote displays 'bump' into each other.

Another thing we could do stereoscopic video conferencing. This is possible in the Portable Library because all the displays are 3D capable. If the user positions two of the cameras/displays towards a view, the two images would be used to produced stereoscopic pairs that result in a three dimensional view of the visual scene.

These enhanced video features are well suited for distance learning and teleoperations such as remote surgery.

Procedure: A Logitech PC QuickCam will be attached to each display so as to face the viewer: http://www.realityfusion.com/gamecam/about_cam.html A Logitech camera is used because it is packaged with the Reality Fusion software: http://www.netsales.net/pk.wcgi/reality/prod/1341273-1 Hopefully this means we will have less of a problem interfacing both the camera and software to LCD displays. The cameras will be connected via a USB port so as to have a small cable footprint. This is necessary to keep the combine weight of the display and camera as low as possible.

Feature: Three-dimensional volumetric reconstruction.

Description: The user of the library can use the cameras to reconstruct a 3D volumetric image of whatever he places in front of the library. If he does this to himself he is also provided with a 3D analogue suitable for use as an Avatar.

Procedure: Several commercial software companies make products that construct a 3D object from pictures of the object from several viewpoints (Gordon, still checking this out). In addition, there is one company, Microlead: http://www.ulead.com/ff/runme.htm that makes software to wrap a picture of a person intelligibly on a generic 3D model of a head. We obtain these products and hopefully SDK's so as to do this in real-time in the library.

Feature: Head Tracking Proprietary and confidential !

Description: Using a I/R tracking device, the users head position is monitored in real-time. This is used for creating a Virtual Window display, and also for any additional features that may need real-time image processing with respect to the users eye gaze.

Procedure: An I/R tracker from Origin Instruments (DynaSight) will be used to provide the tracking: http://www.origin.com/ We use the tracker primarily to gather real-time data so that we can have a realistic Virtual Window display. This is an impressive feature that we should have. A Virtual Window is a close cousin to my device a Portal Display (and its basis). Virtual Windows work by monitoring the head position of the user so that the graphics through a window, such as with an airplane, car, and other vehicles, is accurately recreated for the optical path between the user and the scene. We create an out-the-window scene (in 3D because of the Dimension Technologies coating) such as is needed for a flight or car simulator, where we calculate in real-time the visual scene using the head and display position and orientation provided by the tracker. Using this we have a virtual window. The tracker will also be used in any features that involve a real-time optical correction of the display image.

Notes: Concerning a flat display with no gaps: As was pointed out in describing the Panoramic Viewer, to do so out of multiple displays requires a display with no border. At this point, I am not aware of any available. This is surprising.

There must be a great demand for this characteristic in a display. This feature could be used by all the stadiums and large events to make extremely large configurable displays of any type they need (a display is an analog of a pixel, more pixels more display). We should investigate further to see if this may be a profitable product.

Unfortunately, as of right now I do not know of a way to solve this problem for such a market. In the more limited case of the Portable Library, we have the situation of having only three monitors that can be placed in a side by side arrangement. We may be able to use mirrors and a rearrangement of the viewport to accomplish this. I will present a small article if the interest is there.

Concerning the serial ports: As specified, almost all the I/O is done via the serial port. We should however explore the use of other faster communication methods, for example Firewire. The serial ports are specified to insure a baseline level of communication so as to reduce unknowns and ensure success. A lighter, perhaps wireless, video transmission of high resolution would be the most desirable.

Concerning the motion trackers: As currently envisioned, the Portable Digital Library will have two separate ways of capturing the user's position as well as his gestures. In one way, we make use of the Reality Fusion software to input a user's commands as well as to keep Proprietary and confidential !

track of the position of the displays. In the other way, we make use of an infrared tracking system, typically by tracking a small IR reflective dot on the person's head in real-time.

The IR tracker is an expensive item, and one may think it overkill just to track the user's head position. However other methods, such as mechanical resistance measures or magnetic field monitors etc. all require tethers, in addition some would require substantial engineering to integrate them into the library.

Since we do have another method (Reality Fusion), one may ask why not use it for the head tracking. The software is sophisticated enough to follow and recognize a person's hand gestures. This is done by a real-time analysis of a video image (from a typical inexpensive video cam) of the user.

Unfortunately, since it is a software DSP process, it currently is too slow to use at a 60-Hertz rate. However in the future I think that this method is the one most likely to be useful in a commercial market.

For the library, we use the Reality Fusion video system for other functions, most prominently as a user interface to the web browser and the video/audio controls of the portable library. The software is being continually revised and with a very well supported SDK. It used to be available free of charge, but we now need a developer's agreement of some sort: http://www.realityfusion.com/sdk.htm (Gordon, I will email it when received). An additional use of the Reality Fusion software is unique to the Portable Library. The three displays will each have a separate video camera. This will be used not only to obtain the user's gestures, but also of themselves. This will allow the library to change the video display format (size of desktop, etc) to the correct one for the three main display formats (QTVR viewer, Panoramic Viewer, OTW simulation). It may also allow for the use of the displays as Portal Displays, since although the main requirement is a real-time analysis of both the viewers and the display's position, the display position needs much less bandwidth than that of the user's.

One may ask why we could not make use of the IR tracker for the display positions. Unfortunately, the cost per sensor and tracker makes it very expensive and not cost effective. In addition to the price per sensor, we might have to buy an additional IR tracker. Tracking the monitors with the IR sensor will require more sensors than are available on one unit. We would then have the added expense of buying two I/R trackers. Using of the Reality Fusion method is substantially more cost effective then using an IR tracker.

Figure 1: Portable Library Hardware/Software Configuration This diagram shows the information flow through the hardware and software of the Portable Digital Library. A software box is always inside a hardware box, so, for example, the Library Server is a large gray box containing the boxes naming the server software, the AIQuery Engine, the Crestron web software, and the web browser.

An arrow means a physical connection with the direction being either unidirectional such as with the audio/video signal going to the Wide Screen Monitor (red), or bi-directional such as with the Library Personal Computer Ethernet connection to the server (green).

One thing to notice is that the software AIServer box extends across the hardware box. This is done to signify that the server is indeed the server, such that all interactions between the Internet and any software that needs input or output must pass through it.

The ST-COM, ST-I/O, ST-VC hardware boxes are modules need to do serial communication, bit I/O, and device control (e.g. receiver volume) respectively.

The Digital Library book is a display device with a touch screen used to manipulate web pages, and must be very simple and light. It does not by itself have any user input apart from that used in the touch screen. The main user control will be the touch screen with the display mirroring the server browser, and also the AI AudioResponse System (AiARS).

The position sensors are for monitoring the location of the displays, and also allow for virtual windowing if used in conjunction with a head sensor. One cannot use the Reality Fusion camera method for this because it would be too slow.
