Patent ID: 8443302

Claim:
A display system comprising: a multi-dimensional display device with a surface on which an image can be presented; a plurality of contactless sensors positioned adjacent to the surface; and control circuits coupled to the sensors and the display device, wherein the control circuits establish a first sensing region adjacent to the surface of the display device, the first sensing region having a predetermined shape, and, a second sensing region within the first sensing region, the second sensing region having a different shape than the first sensing region, wherein the control circuits, responsive to signals from the sensors, determine a trajectory of a pointing member in the first sensing region moving toward the surface, and, responsive thereto, vary the image on the surface, and wherein the control circuits, responsive to signals from the sensors, determine a trajectory of a pointing member in the second sensing region moving toward the surface, and, responsive thereto, vary the image on the surface differently than when the pointing member is in the first sensing region and not the second sensing region.
