After I finished my MSc degree in January, I spent the next few months working on a number of projects in the AMMI lab. One of the most fruitful projects was the design and development of the AIR Touch multi-touch system. Working with Fraser Anderson and a team of researchers and occupational therapists at the Glenrose Rehabilitation Hospital, the AIR Touch system is comprised of a 3 foot by 2 foot multi-touch surface (manufactured by NOR_/D), a FireFly MV IR camera, an off-the-shelf NEC projector, a mirror, the openFrameworks software package, and a suite of rehabilitation-inspired multi touch activities written in Adobe Flex. The lovely black 2×4 stand was created by Fraser and I in my garage (thanks Dad for the supplies!).

Version One of the system:

We chose to use a very open solution, as opposed to the Microsoft Surface or a SMART table, so we could modify or add things to the hardware setup as needed. We are currently in the process of designing version two of the hardware and I will post pictures when we are done!
