1. 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, andwherein 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.

Abstract
A contactless display system enables a user to interact with a displayed image by moving a finger, or pointer, toward a selected portion of the image. Images can be enlarged, or translated dynamically in response to detected movement. Operational methodology can be manually switched between contact-type and contactless operation to enhance flexibility.

14. A process comprising:
-
providing a display surface; establishing a first sensing region having a first multi-dimensional shape; establishing a second sensing region within the first sensing region, the second sensing region having a different shape then the first sensing region; sensing movement of an elongated member in the first sensing region, and, responsive thereto, varying a display on the surface; and sensing movement of the elongated member in the second sensing region, and, responsive thereto, varying the display on the surface differently than when the elongated member is in the first sensing region and not the second sensing region. - View Dependent Claims (15, 16, 17, 18)
