Abstract
A gesture-enabled keyboard and method are defined. The gesture-enabled keyboard includes a keyboard housing including one or more keyboard keys for typing and a pair of stereo camera sensors mounted within the keyboard housing, a field of view of the pair of stereo camera sensors projecting substantially perpendicularly to the plane of the keyboard housing. A background of the field of view is updated when one or more alternative input devices are in use. A gesture region including a plurality of interaction zones and a virtual membrane defining a region of transition from one of the plurality of interaction zones to another of the plurality of interaction zones is defined within the field of view of the pair of stereo camera sensors. Gesture interaction is enabled when one or more gesture objects are positioned within the gesture region, and when one or more alternative input devices are not in use.
