Abstract :
InfTouch is a multi-touch technique that tracks any objects with diffuse surface. This technique provides tracking at 25 Hz, and is able to work reliably in hazardous environment. The integration to over-sized displays is simple and convenient. InfTouch has no border, which makes it a good free-air interaction tool. The commercial applications prove the usefulness of our technique.
