Abstract
A technique for creating a virtual touchscreen includes capturing, with a first infrared camera, a first reflection from an object that is at a known position adjacent a surface associated with a device. A second reflection from the object (at the known position) is captured with a second infrared camera. The first and second reflections are correlated with the known position to provide a two-dimensional position for the object that is calibrated with respect to the surface.
