Current Setup of the Terra Portal (as of 3/1/2010) The technology we are using is called Diffused Infrared. This is the method first used to develop multitouch systems. We choose this for a couple reasons. It lends itself to the space we were provided, as well as rear projection. It is quick to prototype, and most importantly, it’s cheap. The process of how it works is quite simple. IR arrays flood a screen, and as your fingers touch the screen, the IR camera picks up the light as hot points. The points, or “blobs” are translated by an open source touch recognition software that tags the blobs and feeds those tags to a server which interprets them as mouse points.

their ‘reinvention’ of a rarely tapped resource. The gesture language that Apple established has become the basis of multiple multi-touch application platforms. With an official patent on multi-touch granted on January 29th, 2009, it will be interesting to see how other companies challenge the medium beyond its constraints.
A Study in Student Collaboration In the Fall of 2009, a very simple question was posed. “Why are the students at a University of so many disciplines, not sharing their knowledge amongst each other?” Who is to say that a dancer and graphic designer, couldn’t enhance each others learning experience through a shared knowledge network? Who is to say a film maker and an actor shouldn’t work together? Seemingly simple questions, turned into a vast

Touchscreen technology is changing everyday. With the screens making the way more and more into the mainstream audience, newer, more responsive systems are being developed. We choose to analyze the 4 most popular systems for commercial usage to date. Resistive. Found in many food ordering systems seen at Wawa, OpenTable, or ATM kiosks. Sonic Accoustic Wave. Can be any shape, including curved, shperical, or organic, and it also works underwater. Capacitive. Iphones, Ipads, as well as other smaller screen mobile devices. Infrared. Wall systems, and touch tables as well as smart boards often utilize this technology.
cross pollination? Through a series of experiments, the study tried to engage the entire UArts community as a whole. The result: 5%. Of 3000 faculty staff and students, only 5% started a line of communication with us. Those, brave 5% of students, faculty and staff actually stepped up, asked what we were doing, and whole-hearted gave themselves up to the greater good. You see, these people are the proactives. These are the artists that look at something, and truly beg to ask the question of why? What are you doing here? And can I be a part of it? They chose to engage in a face to face manner, whether it be with a friend, associate, stranger or mentor.

The goal in addressing this problem was to cut through the printed and online clutter, and provide a clear and easy system that gives students access to information while maintaining a simple method for student input and usability.
