It allows you to use a system that’s very high-bandwidth: your fingers. By detecting the location and movement of your fingers in space — right on down to using the doppler effect to detect speed — you can enable rich interactions. If the science works, it becomes a problem of defining the “vocabulary” of movements. Sliding your thumb against your finger could scroll, tapping them together could select, a flick could dismiss. ATAP is also approaching the problem of interaction bandwidth by providing a larger surface area using touch-sensitive fabric.
