Multi-touch floor display

while multi-touch interactive displays offer a range of possibilities, they can be no larger than the average user’s arm span. this is why human-computer interaction professor patrick baudisch and his team have developed a multi-touch floor display. because of the size limitations with hand controlled interactive surfaces, only a few dozen onscreen objects can be dealt with at one time. baudisch wants to increase the possibilities with by integrating high-resolution multi-touch into back-projected floors. the floor concept can sense pressure and even identify users based on the soles of their shoes. the floor can ignore inactive users, focusing on known users who can use their foot to interact with very high precision. the floor is so precise users can type on a qwerty keyboard using their foot.
