Patent ID: 8681124

Claim:
A system for use with a processor-generated display presented on a display device in a display area, the system recognizing at least one user-object interaction with a region on a surface of said display device, a hover region defined in three-dimensional space spaced-apart from said surface of said display device, and a virtual scroll region defined in three-dimensional space adjacent a peripheral region of said display area, the system including: a first time-of-flight (TOF) system disposed to emit optical energy in a first field of view (FOV) defined generally toward said surface of said display device and to acquire at least a fraction of the emitted said optical energy that is reflected-back by a passive user-object within said first FOV, and to process at least one of z-depth data and A-brightness data within reflected-back said optical energy to discern a probable location in three-dimensional space of said at least one passive user-object interaction; a second system associated with a second field of view (FOV) defined generally toward said surface of said display device, said second system including at least one of a second TOF system, at least one two-dimensional camera, and at least one mirror, wherein said first TOF system and said second system detect at least a passive user-object interaction in a location; a system processor coupled to said first TOF system and to said second system to discern from at least one of processed z-depth data and processed A-brightness data acquired by the first TOF system and the second system the location in three-dimensional space of said at least one user-object, said location being any of (1) a portion of said surface of said display device touched by said user-object, (2) a location in said hover region, and (3) a location in a virtual scroll region, an output of said system processor coupleable to said processor-generated display to affect operation of said display on said display device.
