This is… amazing, just… wow! I am attending RPI this fall as a freshmen, and i plan on going into mechanical engineering and design. As soon as i saw this video i was literally agape and on the edge of my seat! I gave the link to all the other people going to RPI next year including Computer Science, Computer Engineering, and other Mech. Eng.
I have a Nintendo Wii, and an extra controller, so you can count on me bringing this set up to my Dorm room next year. With the interactive 2-point white-board alone i can think of either great fun or great ways to improve on how I do my work. Can this be set up to a CAD software or similar software for 3-D design?

Honestly Mr. Lee, I have so much respect for you right now. First for realizing this could be done, second for developing the software to make it happen, and last but far from least, for making the information widely distributed, the software free to everyone, and as you said, opening the field of research to such a broad range of people. You certainly deserve that standing ovation. Bravo!!!

This is a cheap, scalable multi-touch and pressure-sensitive computer screen interface that may spell the end of point-and-click. 

The future use of multi-touch technology is expected to rapidly become common place. For example, touch screen telephones are expected to increase from 200,000 shipped in 2006, to 21 million in 2012.

While Touch sensing is commonplace for single points of contact, Multi-Touch systems enables a user to interact with a system with more than one finger at a time, allowing for the use of both hands along with chording gestures. These kinds of interactions hold tremendous potential for advances in efficiency, usability, and intuitiveness. Multi-Touch systems are inherently also able to accommodate multiple users simultaneously, which is especially useful for collaborative scenarios such as interactive walls and tabletops.
