Abstract
A system and method is provided for a gesture recognition interface system. The interface system may comprise a first and second light source positioned to illuminate a background surface. The interface system may also comprise at least one camera operative to receive a first plurality of images based on a first reflected light contrast difference between the background surface and a sensorless input object caused by the first light source and a second plurality of images based on a second reflected light contrast difference between the background surface and the sensorless input object caused by the second light source. The interface system may further comprise a controller operative to determine a given input gesture based on changes in relative locations of the sensorless input object in the first plurality of images and the second plurality of images. The controller may further be operative to initiate a device input associated with the given input gesture.
