Multi-Touch Interaction Wall

A 16-foot-long rear-projected interactive display that has the unique ability to sense multiple points of touch from any number of users simultaneously with unprecedented precision and accuracy.

Enhanced Life
While touchscreens that register single points of contact are commonplace, multi-touch systems allow the user to interact with both hands and multiple fingers at the same time. These forms of interaction hold tremendous potential for advances in efficiency, usability, and intuitiveness.

To inspire people to go beyond the mouse pointer, to show how we should be interacting with machines in ways that are more natural, intuitive, and fun.

This is the most sophisticated interactivity ever enabled for a display of this size. It is realized through the exceptional scalability of the frustrated total internal reflection (FTIR) technique for multi-touch sensing.

Multi-touch interaction is one of the most exciting areas in user-interface research and will certainly play an important role when interactive display surfaces are ubiquitous.
