ZeroTouch: a zero-thickness optical multi-touch force field Conference Paper uri icon

abstract

  • We present zero-thickness optical multi-touch sensing, a technique that simplifies sensor/display integration, and enables new forms of interaction not previously possible with other multi-touch sensing techniques. Using low-cost modulated infrared sensors to quickly determine the visual hull of an interactive area, we enable robust real-time sensing of fingers and hands, even in the presence of strong ambient lighting. Our technology allows for 20+ fingers to be detected, many more than through prior visual hull techniques, and our use of wide-angle optoelectonics allows for excellent touch resolution, even in the corners of the sensor. With the ability to track objects in free space, as well as its use as a traditional multi-touch sensor, ZeroTouch opens up a new world of interaction possibilities.
