1. A tiled touch system comprising:
- a display on which a computer-generated image is presented, said display comprising an array of display panels, each display panel having an active display area on which a segment of said computer-generated image is presented, the display areas of adjacent display panels being interrupted by physical gaps, said gaps defining non-active display regions;
at least one digitizer disposed on said display and providing a generally continuous contact surface overlying the active display areas and the non-active display regions corresponding to said gaps, said at least one digitizer being mapped to both said active display areas and said non-active display regions, said at least one digitizer comprising at least two imaging devices looking generally across said contact surface from different vantages and acquiring image frames to detect pointer contacts made on said contact surface over active display areas and on said contact surface over non-active display regions; and
at least one processing unit responsive to pointer data received from said at least one digitizer and updating said computer-generated image in response to detected pointer contacts on said contact surface, wherein mapping of said at least one digitizer to both said active display areas and said non-active display regions is performed during an orientation procedure, and wherein during said orientation procedure, said at least one processing unit updates the computer-generated image so that each display panel displays a plurality of orientation points.

Abstract
A tiled touch system comprises a display on which a computer-generated image is presented. The image is formed of an array of image segments. A digitizer is mapped to the display and senses pointer contacts made thereon.

19. A tiled touch system comprising:
-
a display comprising a plurality of display panels, each of said display panels comprising a matrix of display pixels defining an active display area and a border surrounding said display area thereby to interrupt said display and define non-active display regions, each display area presenting a portion of an image; a digitizer comprising a continuous, generally transparent rigid pane on said display and defining a contact surface overlying both said active display areas and said non-active display regions, the contact surface of said transparent pane being mapped to said active display areas and said non-active display regions, said digitizer further comprising at least two imaging devices looking generally across said contact surface and capturing image frames from different vantages; and at least one processing unit responsive to pointer data output by said digitizer and updating the image presented by said display in response to detected pointer contacts on said contact surface, contacts on said contact surface initiating at locations that are mapped to non-active display areas corresponding to the borders being recognized by said at least one processing unit as input command events, wherein the contact surface of the transparent pane is mapped to the active display areas and the non-active display regions during an orientation procedure, said mapping compensating for at least some of positional, scaling, rotation and keystone errors, and wherein during said orientation procedure, said at least one processing unit updates the computer-generated image so that each display panel displays a plurality of orientation points. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 34)

37. A tiled touch system comprising:
-
a display on which a computer-generated image is presented, said display comprising an array of display panels, each display panel having an active display area on which a segment of said computer-generated image is presented, the display areas of adjacent display panels being physically separated by gaps, said gaps defining non-active display regions; a digitizer disposed on said display and providing a generally continuous contact surface overlying both said active display areas and said non-active display regions corresponding to said gaps, the contact surface being mapped to both said active display areas and said non-active display regions, said digitizer comprising at least two imaging devices looking generally across said contact surface from different vantages and acquiring image frames to detect pointer contacts made on said contact surface over active display areas and on said contact surface over non-active display regions, said digitizer tracking pointer movements on and across the non-active display regions between adjacent display panels; and at least one processing unit responsive to pointer data received from said digitizer and updating said computer-generated image in response to detected pointer contacts on said contact surface, wherein mapping of said contact surface to both said active display areas and non-active display regions corresponding to said gaps is performed during an orientation procedure, and wherein during said orientation procedure, said at least one processing unit updates the computer-generated image so that each display panel displays a plurality of orientation points. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
