Abstract Originally a mouse is a device in computer graphics interface. The mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer.

But change the value of the mouse position which has long been in conjunction with graphical elements in a variety of interactive media authoring tool is used to interact with the user.

This thesis focuses on various of experiment using digital data and actuator. The digital data that can be transformed and used in many analog form. The techniques such as physical interaction and projection mapping and kinetic motion have been experimented. The first phase of the project is about sound and image. The second phase of the project is about physical sound. Buy the third phase of the project is about kinetic physical and graphical motion. The final project is consist of Dj Turntable with mouse and standard stewart platform is consist of actuator and realtime motion capture system.

This thesis proposes a experiment about expandability as an interactive media controller using a mouse and a production of work about media interactive. Furthermore, goal is to make a new interactive media platform that used in several places.

1. Introduction

1.1 Motivation

Figure 1. Marionettes

This main subject is on the controlled object and device. This image is about string puppets. This puppet is controlled by control bar. Marionettes, or "string puppets," are suspended and controlled by a number of strings, plus sometimes a central rod attached to a control bar held from above by the puppeteer. The control bar can be either a horizontal or vertical one. Basic strings for operation are usually attached to the head, back, hands (to control the arms) and just above the knee (to control the legs). This form of puppetry is complex and sophisticated to operate, requiring greater manipulative control than a finger, glove or rod puppet.1

http://en.wikipedia.org/wiki/Marionette

An important point to notice here is that the story depends on movement of puppet. Just a small but nevertheless important point. We can make a image or sound or story by controlling something. That is what I want to focus on.

1.2 Background

The focus of thesis is on a device. We everyday use various devices. Computer may be the best example of this. Computer work by using various I/O devices. In Computer system, Communication using device is an important aspect to communication. And a mouse is used to control something in computer system. A mouse typically controls the motion of a pointer in two dimensions in a graphical user interface. The mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer.

But analog signals of control bar and digital signals of mouse are different form. With analog communications, data is represented as a continuous signal while data is converted to a numeric, discrete signal with digital communications. Also They controls something. In this, That is similar to the puppetâ&#x20AC;&#x2122;s control bar.

1.3 Goal

This goal of thesis is making a total interactive media platform based on technique of mouse for playing a media performance. Also That is various approaches on actuator controlled by mouse.

The truth is that most media artist and performer are working based on the high technology. So theirs works is often type of digital form. 2

Applying visual Art to pop music performance is gradually increasing. A video editor which simply mixes a number of image was mainly used in the past, but now various computer software make it easy to control visual art by development of computer technology, and it became possible for you to express unique and inimitable idea as well. Compare that a complicated equipment which makes them spend much expense and time was only used in the big size of concert hall in early days, a small and simple one now helps you easily apply your idea to Visual art in Pop music performance even in the small club. The technique of Visual art is being developed gradually especially by using computer.2 I am very interested in analog sound and motion and image.

2. Design Methodology

The area of research in this thesis focused on device and interactivity for the interactive media and real time visual performance. This thesis focused on the interactivity and physical interaction and realtime visual performance.

Above all This goal of thesis is making a total interactive media platform based on technique of mouse for playing a media performance. So the theoretical background and case study research include a review of New Media Art which focused on Digital Art and Physical Computing. And It include a general background about a VJing and Puppetry and Device. Because This thesis’s core theme is control which is based on device and interactivity.

Interactive media allows the user to have control over navigation and interactivity with the information. The nature of interactive media is dynamic and changes through time. To support this dynamic change, knowledge of how to communicate information efficiently beyond static representation needs exploration. Motion is a key element in interactive environments. Motion helps the user to perceive a change of state.3

2.1 Interactivity

Researchers, practitioners and scholars have varying views on the very definition of “interactivity.” There is no single, authoritative definition. People have used the word to describe a wide range of action. From a sociological perspective it has been defined as actions conducted between two or more people, and in the field of 3

C Jeamsinkul, S Poggenpohl. “Methodology for uncovering motion affordance in interactive

media”. Visible Language, (2002), Vol.36 (No. 254)

human-computer interaction it has been applied to the style of control that exists for humans working with computers. Various researchers and professionals have begun to isolate its characteristics.4

The definition of the interactivity is various. Because the evaluation of the interactivity factor for interaction with computer and human. In The Language of New Media (2001), Lev Manovich (http://www.manovich.net/) proposed five principles of new media: numerical representation, modularity, automation, variability, transcoding. Two-way+ use can be said to represent interactive digital media.5

In 2000, Downes and McMillan (http://nms.sagepub.com/cgi/reprint/2/2/157) noted that researchers in the 1990s argued about whether only real-time communication could be considered to be “interactivity.” For instance, Steur (1992) defined it as “the extent to which users can participate in modifying the form and content of a mediated environment in real time” but Rheingold (1993) wrote that asynchronous tools such as listservs, e-mail and newsgroups are interactive.6

But In new media art interactivity has taken on yet another form. In new media art the goal is not only for a cause and effect action or real time control over the object but an interplay between the objects and the users. Interactive new media art puts the viewer in a more active role; the "viewer" becomes responsible for the content of the interactive piece through their actions. Or simply the interactive "experience" is different for each different user because each user will 4 5 6

respond to the piece in a different way.7

2.2 Case Study

2.2.1 Background

A look at the existing interactive art that interacts with musical performances or MIDI music try to increase the participation and realism of the audience using expensive equipment and the latest technology. But the audience are not sometimes impressed by system which is too biased in high technology and equipment.8

Because movie and sound that were empty of meaning are often made by high technology and equipment.

Above all, most of movies and sounds in interactive performances is synthesized by the interactive authoring tools in real time. The movies and sounds in the interactive performances are stereotyped as well.

2.2.2 Visual Performance

This cases study focus on interactive visual performance. The input data are used to control interactive movie and sound. The type of my final project is interactive visual performance and installation. I use a input data of mouse and Dj Turntable which is used to controller. 7

http://newmedia.wikia.com/wiki/Interactivity

8 Yi-xian Li, Chang-jin Seo. â&#x20AC;&#x153;A study on Interactive Media Art on Physical Computing Technologyâ&#x20AC;?. (2012),

p193

Input data is very important for interactive performances. Because, Most of the interactive movie and sound use a input data.

Input is the term denoting either an entrance or changes which are inserted into a system and which activate or modify a process. It is an abstract concept, used in the modeling, system design and system exploitation. It is usually connected with other terms, e.g., input field, input variable, input parameter, input value, input signal, input port, input deviceand input file.9

Case_01

Figure 2. 16 Forms

Daito Manabe and Motoi Ishibashi (both whom conveniently, for me, carry the same title: artist, designer and programmer) are presenting â&#x20AC;&#x153;16 forms,â&#x20AC;? an animated sequence that is both analogue and high-tech. Programming an industrial robot to create dynamic movements while projecting a light source, the duo created their own version of a zoetrope. While conventional zoetropes make use of paper cut-outs, Manabe and Ishibashi opted for scanned and 3D-printed models, which were then affixed to a turntable.10

http://www.spoon-tamago.com/2011/11/02/designtide-tokyo-2011-daito-manabe-motoi-ishibashi

This project is an example of an analog media that was work using turntable. The ‘16 Forms’ show the turntable is capable of making a analog animation. Because It is used a zoetrope.

A zoetrope is one of several pre-film animation devices that produce the illusion of motion by displaying a sequence of drawings or photographs showing progressive phases of that motion. The name zoetrope was composed from the Greek root words ζωή zoe, "life" and τρόπος tropos, "turning".

The zoetrope consists of a cylinder with slits cut vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures. As the cylinder spins, the user looks through the slits at the pictures across. The scanning of the slits keeps the pictures from simply blurring together, and the user sees a rapid succession of images, producing the illusion of motion. From the late 20th century, devices working on similar principles have been developed, named analogously as linear zoetropes and 3D zoetropes, with traditional zoetropes referred to as "cylindrical zoetropes" if distinction is needed.11

Case_02

Figure 3. Liquid Light Show

Liquid light shows surfaced on both sides of the Atlantic around 1966 and were an integral part of the Progressive music scene well into the seventies. Shows could be as simple as a single operator and two or three modified slide or overhead projectors and a couple of color wheels or as complex as shows with ten or more operators, 70 plus projectors (including liquid slide, liquid overhead, movie and still image models plus a vast array of highly advanced (for the time) special effects equipment).

The style and content of each show was unique but the object of most was to create a tapestry of multimedia live event visual amplification elements that were seamlessly interwoven, in a constant state of flux and above all, reflected the music the show was attempting to depict in emotional visual terms. 10

While the shows on both side of the Atlantic had much in common they differed in two important ways. First, the American shows tended to be larger, with seven operators and over thirty projectors not being exceptional. In contrast, the shows in England seldom had more than three operators and ten or so projectors. Second, American shows were generally built around the overhead projector with the liquids in large clock cover glasses.

Shows in England and Europe, in contrast, used modified 2" sq. slide projectors which had their Dichroic heat filters (one or both) removed and employed two layers of slide cover glasses with two liquids (oil and water based, in the early days) between each layer. The surface tension of the liquids largely retained the mixtures, but the process was nevertheless very messy indeed and operators had their hands almost permanently stained by the dyes. A popular choice of coloured liquids for lightshows was Flo-Master ink, a product developed for use in permanent marker pens. While this ink was very vivid it also had the problem of staining the operators hands very deeply.

Two groups that are associated with the light shows they worked with above all others are Jefferson Airplane and the Headlights light show in America and Pink Floyd with light artist Mike Leonard in England. The inverter of the light show is David Gun.12

2.3 Input Device

Input variables are defined as the physiological and psychological variables related to the persons creating visual phenomena, or started simply: the conditions surrounding creators or artists. These variables are not concerned with the images 12

http://en.wikipedia.org/wiki/Liquid_light_show

being created, but with creators’ identities, motivations and techniques for passing intentions into media tools.13 The input of tool is position data of computer mouse. It is very simple system. Tool-input variables are concerned with the tools required for creating imagery in a particular medium. Two Tool-Input variables are identified: Tool Requirements and Tool Versatility.14 This variable refers to the minimum tools required for creating visual imagery within a specific medium. In the paint medium, the absolutely minimum tools are paint and supports. Brushes are actually not necessary for painting, although they enable certain effects unobtainable with paint taken directly from tubes. With the video environment, one requires devices capable of producing or manipulating video signals, Such as video cameras, graphics computers or video players.

In this thesis, The mouse is used in input tool. The mouse is combined with Dj Turntable for visual performance.

Concerned with versatility of the tools used in particular media, this variable recognizes the variety of functions capable with a specific tool. An example of an extremely versatile tool is the paint brush which can paint in oil, acrylic or water colours, can manipulate dry charcoal with the bristles, and glue, clay or plaster with the handle. Although a video camera could be used for mixing paint or forming clay, these acts may damage the device’s intended function of converting visual imagery into electronic signal.

2.3.1 Definition

The device is commonly defined as an any machine or component that attaches to a computer. The devices are classified as disk drives, printers, mice, keyboard, speaker, mic, monitor, etc. Computer mice are the most common, commercially used devices for interaction between humans and computers. A major aspect of these devices is to detect and track a desired screen position as the mouse device is being moved by the user, this information being used to move the mouse cursor accordingly.15

2.3.2 Mouse

In computing, a mouse is a pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface. Physically, a mouse consists of an object held in one's hand, with one or more buttons. Mice often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input.16 The main purpose of a mouse as an input device is to translate the motion of the human hand into signals that a computer can use.17So it is very important to thesis project. Because The signal of mouse is used in input data for making a sound and movement using an actuator.

2.4 Conclusion

The important component of interactive media is an interactivity. Because It is make a communication between person and media. If you input into visual media, imagery is being created; this imagery is then output to viewers of media. Communication with media utilizing the terms outlined is presented in Figure 1. As outlined in this diagram, the intentions of the creator are input into a tool capable of manipulating some material which retains imagery. When the creator views the image, the image is viewed through a tool as well. In this condition the creator becomes the viewer also, but in most situations other than the initial creation process, the viewer will not participate in the creation of imagery but will only view previously created imagery.18

So I use a mouse and Dj Turntable for input tool. This system which is consist of mouse and Dj Turntable is useful in this thesis.

In the sound recording industry, a stylus is a phonograph or gramophone needle used to play back sound on gramophone records, as well as to record the sound indentations on the master record. Several technologies were used to record the sounds, beginning with wax cylinders, almost half a century before the invention of the magnetic cartridge. Nowadays mostly vinyl records are used. When playing the record, the stylus is placed in the grooves of the record.20

This system is very simple. I simply convert a stylus into mouse for interactive system. This system is capable detecting the movement of hand on the Dj Turntable. I expect that many designer and artist are using a mouse for visual performance and interactive media.

3. Development Environment

3.1 Arduino

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. Arduino projects can be stand-alone, or they can communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.) The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free. The Arduino programming language is an implementation of Wiring, a similar physical computing platform, which is based on the Processing multimedia programming environment.21

3.2 Processing

Processing is an open source programming language and integrated development environment (IDE) built for the electronic arts, new media art, and visual designcommunities with the purpose of teaching the fundamentals of computer programming in a visual context, and to serve as the foundation for electronic sketchbooks. The project was initiated in 2001 by Casey Reas and Benjamin Fry, both formerly of the Aesthetics and Computation Group at the MIT Media Lab. One of the stated aims of Processing is to act as a tool to get non-programmers started with programming, through the instant gratification of visual feedback. 21

http://arduino.cc/en/Guide/Introduction

The language builds on the Java language, but uses a simplified syntax and graphics programming model.22

4. Experiment and Prototype

4.1 Prototype_MouseTurntable

4.1.1 Idea

Figure 5. Idea

Dj Turntable is very useful tool for interactive media installation and performance. The sound change with the change of hand gestures. And a turntable can offer to combine other instrument and kinect object and something. The turntable is not just an instrument for playing music, but creating it. I think that computer mouse is also a very useful tool for interactive design.

Because A mouse is used to

control something in computer system. A mouse typically controls the motion of a pointer in two dimensions in a graphical user interface. The mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer. So A simple media controller which is made a combination of turntable and computer mouse. 18

4.1.2 Sketch

Figure 7. Laser Cutting

This is drawing for mouse case is connected to the turntable. I design it using CAD( 2D and 3D Program). It very useful tool for design something. After designing it, I make a case using Laser Cutting Machine. 19

4.1.3 Process

First I had to disassemble the used laser mouse in order to make new mouse for replace the needle. And I make a case for mouse. First I disassemble the mouse.

4.1.6 Projection Mapping

I experiment projection mapping test on the tree. More specifically, This is not projection mapping. Because It showed simple actions. I propose to experiment it at some length.

Figure 17. Sequence_Projection Mapping

4.1.7 Conclusion

This Prototype is first experiments about an expansibility of mouse. And The experiment will have shown the potential for mouse and Dj Turntable. Because I get a position data of hand movements from Dj Turntable. So I was able to make a image using a interactive media tool. The Movement of hand convert into digital code by interactive media tool. The signals enter the VVVV through the Arduino. It is very simple system. After this System used in Final Prototype.

4.2 Experiment_Motion Sound

4.2.1 Idea

Figure 18.System

Whenever I listens to music, I shake my head up and down or side to side. It is quite simple motion. But I think that I have more motion data available. Because It have many position data value. I can use it as method to Express motion to another form. Example sound or moving object or motion graphic. First I using motion data to express and converting motion data to vibration.

4.2.2 Technique Research

I decide to use Arduino for my project. And to do that. I need to understand the basic some knowledge of Electrical and Electronic. I research about DC Motor Circuit. Some diagrams illustrating how to use the tip120 transistor to control 12 v (actually up to 60v dc)

Figure 19. TIP12023

Transistors are powerful little electronic switches, and when our little NPN transistors aren't power enough for your project, we have been known to use these beefy TIP120 Darlington transistors. Great for whenever you need to control

medium to high-power electronics such as motors, solenoids, or 1W+ LEDs.24

Figure 20. 1N400125

The 1N4001 series (or 1N4000 series) is a family of popular 1.0 A (ampere) general purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. Blocking voltage varies from 50 to 1000 volts. This diode is made in an axial-lead DO-41 plastic package. The 1N5400 series is a similarly popular series for higher current applications, up to 3 A. These diodes come in the larger DO-201 axial package.These are fairly low-speed rectifier diodes, being inefficient for square waves of more than 15 kHz. The series was second sourced by many manufacturers. The 1N4000 series were in the Motorola Silicon Rectifier Handbook in 1966, as replacements for 1N2609 through 1N2617. The 1N5400 series were announced in Electrical Design News in 1968, along with the now lesser known 1.5 A 1N5391 series. These devices are widely used and recommended.26

Figure 26. Idea

I made a mouse controller for Dj turntable last week. It has a very simple controller that moved with up and down. Shaking a head to the rhythm the music is similar to moving mouse with up and down. So I think that shaking motion data is useful for controlling something. So Using a VVVV, I make a tracking system for controlling a vibration motor.

4.2.5 Conclusion

The second prototype is new experiments in another way and focused on making a sound. I use a signal from movement of head. The motion data is useful for interactive media. Because It is similar to position data of mouse. So I can used in input data. The signal of motion data was readily available.

4.3 Experiment_Vibration Sound

4.3.1 Process

I put the new circuit to test. First I connect four vibration motor with electrical wire. And I control it with VVVV. The vibration motor and circuit is full of lifelike. The experiment was interesting and very informative for me. And it was difficult work but inspired.

4.4.4 Conclusion

This prototype to include the elements of sound and image was successful. I have shown that the visual performance based on mouse interaction. The purpose of this prototype is a combination of virtual image and real image and sound. I want to put the hybrid space into the interactive media. Projection mapping, also known as video mapping and spatial augmented reality, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings. By using specialized software, a two- or three-dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative.27 I using a method which is projection mapping for expressing mixed real and fake. This prototype became an inspiration to next prototype.

4.5 Prototype_Kinetic T-shirts

4.5.1 Idea

This idea is from Kinect Sculpture. This project is experimental prototype on the kinetic object and extensity of mouse. This shirts works by actuator using a position data of mouse. The signal of mouse into the actuator. So It can move. The servo is similar to controller of puppet. And T-Shirts is kinetic object. This system is simple. It is consist of Arduino and Servo. This system is composed of a source of energy, inputs, outputs, and a control architecture which converts the information from the inputs into information which stimulates the outputs. These elements sum to form the complete object, but other elements may be added to provide mass or form.

Input The interface between the object and the world is its sensors which convert physical stimuli into electrical signals. For example, a sound wave moving through the air may vibrate a tiny diaphragm within a microphone and this vibration modulates an electrical signal which accurately reflects the sound in the environment. This analog electrical signal must then be sampled into a digital signal so that it is valuable to the control system. This process is known as an analog to digital conversion or ADC. There are many different sensing mechanisms that may be employed for creating an aware object including light detection, motion detection, sonar, a video camera, touch sensors, gyroscopes, etc.

Output The output of a behavioral kinetic object allow sit to communicate and to achieve its goals. For example, through moving its motors in a purposeful and 47

synchronized manner a object may project the emotion of anger or may attract the attention of a passerby if it needs attention. A object may use actuators such as standard motors, servos, solenoids, or hydraulics to create movement.

Control The control system for a behavioral kinetic object is a set of rules that creates behavior through mapping the input and the output. To achieve this task it must store the information about the current state of the environment and possibly information about the previous state of the environment.28

This Simulation is about a movement of servo. The servo are moved by signal of mouse. The movement is simple. The shirts is move straight up and down by servo.

4.5.4 Development

I want to show a topographical T-Shirts through movement of them. First I taping the front of the T-Shirts with a narrow black tape. And I make a image using VVVV. This purpose of Prototype is an experiment on digital image and analog Image. The image on the shirts is real. But the projection of image on the shirts is fake. There are both real and fake. Above all, I have on focusing on expandability of a Dj Turntable with a Computer Mouse. 49

4.5.7

Conclusion

The final experimental prototype was very interesting for me. Because It is first system which is used for making kinetic motion. The word kinetic is only understood in reference to the word kinematic. As originally defined by Andre Ampere in 1830, kinematics is the study of motion unattached to forces or objects and is therefore only consider ideal situations. Kinetics, on the other hand, is concerned with motions resulting from forces directly connected with systems. Alexander Calderâ&#x20AC;&#x2122;s Untitled mobile built in 1976 is an example of kinetic motion. Kinematics can only be studied in the mind, on paper, or in a digital environment, while kinetics can only be studied in the real world using physical matter acted on by external forces. Kinetics is therefore inherently associated with physical sculpture and a work of sculpture completely realized inside a computer is therefore a kinematic sculpture.29 The servo was first used in this prototype. It is 29

Casey Reas. â&#x20AC;&#x153;Behavioral Kinetic Sculptureâ&#x20AC;?. Massachusetts Institute of Technology. (2001), p.20

very useful for kinetic project. It has a very simple motion. So I easily can use it. And I find it about a potential of servo.

5. Final Project

5.1 Concept

The subject of thesis is about controlled object by using a device. In general, a device is a machine designed for a purpose. In a general context, a computer can be considered a device. In the context of computer technology, a device is a unit of hardware , outside or inside the case or housing for the essential computer (processor, memory, and data paths) that is capable of providing input to the essential computer or of receiving output or of both. When the term is used generally (as in computer devices ), it can include keyboards, mouses, display monitors, hard disk drives, CD-ROM players, printers, audio speakers and microphones, and other hardware units. Some devices such as a hard disk drive or a CD-ROM drive, while physically inside the computer housing, are considered devices because they are separately installable and replaceable. With notebook and smaller computers, devices tend to be more physically integrated with the "non-device" part of the computer.

This final project is the potential about Analog Turntable. A turntable or phonograph is a device for playing sound recording. But I use a Turntable as controller which is controlled object.

In computing, a mouse is a pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface. Physically, a mouse consists of an object held in one's hand, with one or more buttons. Mice often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input. Final Prototype is about a Turntable and Mouse. I had been looking for ways to 54

combine Mouse and something. I think that Dj Turntable is similar in movement. I believe that a combination is well possible to do it.

5.2 Idea

Figure 56. Idea for Final Project

This system is consist of one Projector and Stewart platform and Two Dj turntable. Stewart platform is controlled by signals of mouse in turntable. And camera realtime capture oil and water in box on the stewart platform. It is projected on the wall. Oil and water are two liquids that are immiscible â&#x20AC;&#x201C; they will not mix together. Liquids tend to be immiscible when the force of attraction between the molecules of the same liquid is greater than the force of attraction between the two different liquids. In simpler terms, like dissolves like.

Although this experiment uses the same volume of oil as water, the two liquids 55

have different masses and therefore, different densities. A liquid that is less dense than water will float on the water; a liquid that is more dense will sink. Density is a measure of how much of a substance is contained in a specific volume of liquid.

Oil and water will be used in graphic elements. Because They are never mixed up. So They are many potential as a graphic elements. And Also It can be dyed. So made a various colorful image.

5.3 Platform

The Stewart Platform is a classic example of a mechanical design that is used for position control. It is a parallel mechanism that consists of a rigid body top plate, or mobile plate, connected to a fixed base plate and is defined by at least three stationary points on the grounded base connected to six independent kinematic legs. Typically, the six legs are connected to both the base plate and the top plate by universal joints in parallel located at both ends of each leg. The legs are designed with an upper body and lower body that can be adjusted, allowing each leg to be varied in length. See picture to the right The position and orientation of the mobile platform varies depending on the lengths to which the six legs are adjusted. The Stewart Platform can be used to position the platform in six degrees of freedom (three rotational degrees of freedom, as well as three translational degrees of freedom). In general, the top plate is triangularly shaped and is rotated 60 degrees from the bottom plate, allowing all legs to be equidistant from one another and each leg to move independently of the others.30

5.3.1 Stewart Platform

Figure 57. Stewart Platform31

I research a suitable device for thesis. Some of the devices are creative and unique. It is a stewart platform. The Stewart platform design is extensively used in flight simulation, particularly in the so-called full flight simulator for which all 6 degrees of freedom are required. This is consist of actuators. It makes a movement of platform. These are the three linear movements x, y, z (lateral, longitudinal and vertical), and the three rotations pitch, roll, & yaw.32 In mechanics, the degree of freedom (DOF) of a mechanical system is the number of independent parameters that define its configuration. It is the number of parameters that determine the state of a physical system and is important to the analysis of systems of bodies in mechanical 31 32

engineering, aeronautical

http://en.wikipedia.org/wiki/Stewart_platform http://en.wikipedia.org/wiki/Stewart_platform

engineering, robotics,

and structural

engineering. The position of a single car (engine) moving along a track has one degree of freedom, because the position of the car is defined by the distance along the track. A train of rigid cars connected by hinges to an engine still has only one degree of freedom because the positions of the cars behind the engine are constrained by the shape of the track. An automobile with highly stiff suspension can be considered to be a rigid body traveling on a plane (a flat, two-dimensional space). This body has three independent degrees of freedom consisting of two components of translation and one angle of rotation. Skidding or drifting is a good example of an automobile's three independent degrees of freedom.33

5.3.2 Technical Subject

The Stewart Platform is a space truss comprised of six prismatic actuators, each mounted by a universal joint to the manipulator base by and by a spherical joint to the top platform. Figure. 58 depict a typical Stewart Platform. This arrangement of actuators allows the platform to be placed in and position and orientation(i.e. with six degrees-of-freedom) within a certain volume of space.34

free. The Arduino programming language is an implementation of Wiring, a similar physical computing platform, which is based on the Processing multimedia programming environment.38

5.6.2 Simulation

Before I made the stewart platform, I wanted to know how a servo was working. So I operate it with a mouse. This thing worked well, but it wasnâ&#x20AC;&#x2122;t enough. 5.8 Final Model

After the raw parts of a final model is made by laser cutting machine, these are processed. The process is called a sanding. This is a kind of common finishing methods. I want to a clear body of Stewart Platform. So I choose a methods of sanding.

Figure 75. Sanding

http://arduino.cc/en/Guide/Introduction

All methods of sanding will result in the removal of machining marks, and produce a matte finish. The choice of hand, palm, random orbit, disc, belt, or drum sanding, depends on the quantity, size and shape of the acrylic sheet. Like sanding wood, work from coarse to fine paper. Use light pressure, and keep the part or sander moving to avoid heat build up After sanding, the edge is ready for buffing or flame polishing.39

The test found problems with the box. The box's much too heavy for Stewart platform to lift. Also the load is too long. So A reaction has set in.

5.8.4 Solving the Problem

In the past experiments, The box have some problems. It is about a weight. So I need to look at ways of lightening that box. I change the size of box. So The new box is smaller and lighter.

5.8.5 Testing a Optical Mouse and DJ Turntable

This system is test version using a Optical mouse and Dj Turntable.

Figure 107. Stewart Platform and Circuit

Figure 108. Optical Mouse and Dj Turntable

5.8.6 Testing a Final System

This is main system for interactive performance. I use a mechanical mouse. It can be used in combination with other system. It is a useful device and has a very simple motion system. The mouse on the left turntable is y-axis.The mouse on the right turntable is x-axis.

Mechanical mouse The ball mouse has two freely rotating rollers. They are located 90 degrees apart. One roller detects the forwardâ&#x20AC;&#x201C;backward motion of the mouse and other the leftâ&#x20AC;&#x201C; right motion. Opposite the two rollers is a third one (white, in the photo, at 45 degrees) that is spring loaded to push the ball against the other two rollers. Each roller is on the same shaft as an encoder wheel that has slotted edges; the slots interrupt infrared light beams to generate electrical pulses that represent wheel movement. Each wheel's disc, however, has a pair of light beams, located so that a given beam becomes interrupted, or again starts to pass light freely, when the other beam of the pair is about halfway between changes.40

The data of mouse position is used to operating a actuator. Example these are servo motor and vibration motor and stepping motor. In this final project, The servo motor is used to making a movement.

Actuator An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. An actuator is the mechanism by which a control system acts upon an 40

environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.41

At first, I experiment movement of a stewart platform which is operated by two turntable.

Figure 111. Total System

First If you move turntable, the signal data of mouse is transferred to the arduino. The arduino is used to input data into six servo motors. And then, The stewart platform changes posture according to your hand movement.

5.8.7 Structure for Capture System

The loads need to be a little shorter. Because The stewart platform has a problem in the previous experiment. The load is too long. So its condition was unstable. I change a shorter load. So The stewart platform is more stable than previous that.

And I design a structure for a camera tracking system. Above all, The mobile phone is used to tracking oil in box. Because The resolution of webcam has a problem in the previous system. And It is difficult in the focus. It has no function for changing focus.

After assembling the mobile phone and structure, I put some oil in the box. And I mix water with blue acrylic paints. The water and oil is administered by injection device. It's very useful device.

In the classroom, I simulate a final project. It is very successful simulation. But There are some problems with the final model. First The ration of water to oil was only 2:1. So I could't see movement of oil.

6. Conclusion

This thesis is about a analog image that are made by interactive platform based on the device. Nowadays, The visual performance is common. The VJing is a popular performance for realtime visual performance. A significant aspect of VJing is the use of technology, be it the re-appropriation of existing technologies meant for other fields, or the creation of new and specific ones for the purpose of live performance. There are many types of configurations of hardware and software that a VJ may use to perform. So Vj make a digital image and sound using many software and hardware. But The process is very complicated.

So This thesis focused on the common device which is used as a input device. I choose the mouse which fits for interactive media and make a interactive media platform.

First prototype is first experiments about an expansibility of mouse. And The experiment will have shown the potential for mouse and Dj Turntable. The second prototype is new experiments in another way and focused on making a sound. I use a signal from movement of head. The motion data is useful for interactive media. Because It is similar to position data of mouse. The purpose of third prototype is a combination of virtual image and real image and sound. The final experimental prototype was very interesting for me. Because It is first system which is used for making kinetic motion. Final Project is focused on media platform which is able to making a analog image.

I arrived at the final project by a various process of experiments. And I was able to making a image that I want through the new interactive media platform. I want this project to be available to the public, and hope it will became an important new interactive media platform for VJ. 116

Abstract(국문초록)

일반적으로 마우스는 컴퓨터 그래픽 인터페이스로 쓰이는 디바이스이다. 마우 스는 손의 앞뒤 좌우의 움직임에 상응하는 전자 신호로 바꾸어 포인터를 움직 이는데 사용되어 진다.

그러나 다양한 인터렉티브 미디어 자작툴에서 마우스의 위치값은 사용자와 그 래픽적 요소들과 상호작용하는데 사용되어 진다.

이 논문은 디지털 데이터와 엑추에이터를 사용한 다양한 실험들에 초점을 맞 추었다. 디지털 데이터는 변형되고 아날로그의 형태로 사용될 수 있다. 피지컬 인터랙션과 프로젝션 맵핑 그리고 키넥틱 모션과 같은 기술들을 실험하고 있 다. 프로젝트의 첫번째 단계는 소리와 이미지에 과한 것이다. 두번째는 피지컬 사운드에 대한 것이다. 그러나 세번째는 키네틱 피지털 그리고 그래픽 모션에 관한 것이다. 마지막 프로젝트는 마우스와 결합된 디제이용 턴테이블과 엑추 에이터와 실시간 모션 캡쳐 시스템과 결합된 스튜워트 플랫폼으로 구성된다.

이 논문은 인터렉티브 미디어 컨트롤러로 사용되어지는 마우스의 확장성에 대 한 다양한 실험과 인터렉티브 미디어 작품을 제안한다. 더 나아가 여러곳에서 사용되는 새로운인터랙티브 미디어 플랫폼을 만드는 것이 목표이다.
