Large scale touch system and methods for interacting with same
First Claim
1. In a large scale touch system having a touch surface on which a displayed image is presented, a method of facilitating user interaction with said displayed image comprising:
- displaying a scaled version of at least a portion of said displayed image on said touch surface at a user accessible location; and
mapping the scaled version to the corresponding portion of said displayed image so that user interactions with the scaled version are translated to interactions with said displayed image.

Abstract
A touch system comprises a large scale touch surface on which an image is presented and at least two imaging devices looking across the touch surface and having overlapping fields of view. Processing structure communicates with the imaging devices and processes image data acquired by the imaging devices to determine pointer contacts on the touch surface using triangulation. The processing structure further executes at least one application to facilitate user interaction with the touch surface. Methods of interacting with the touch surface are also disclosed

5. In a large scale touch system having a touch surface on which a displayed image is presented, a method of facilitating user interaction with said displayed image comprising:
-
defining a text input region on said touch surface adjacent a user accessible location;
detecting text input into said text input region; and
displaying the detected input text in a text display region spaced from said text input region. - View Dependent Claims (6, 7, 8, 9)

14. In a large scale touch system having a touch surface on which a displayed image is presented, a method of facilitating user interaction with said displayed image comprising:
highlighting at least one displayed object which requires user interaction to provide strong visual feedback concerning the existence of said at least one displayed object. - View Dependent Claims (15, 16, 17)

18. In a large scale touch system having a touch surface on which a displayed image is presented, a method of facilitating user interaction with said displayed image comprising:
-
reproducing at least one region of said displayed image on said touch surface at a user accessible location; and
mapping the reproduced region to the corresponding portion of said displayed image so that user interactions with the reproduced region are translated to interactions with the corresponding portion of said displayed image. - View Dependent Claims (19, 20, 21)

22. In a large scale touch system having a touch surface on which a displayed image is presented, a method of facilitating user interaction with said displayed image comprising:
-
displaying a mouse object on said touch surface;
detecting pointer interactions on said touch surface within said mouse object; and
processing mouse events corresponding to said pointer interactions in a manner to avoid input focus being shifted to said mouse object. - View Dependent Claims (23, 24, 25, 26)

27. A touch system comprising:
-
a large scale touch surface on which an image is presented;
at least two imaging devices looking across said touch surface and having overlapping fields of view; and
processing structure communicating with said imaging devices and processing image data acquired by said imaging devices to determine pointer contacts on said touch surface using triangulation, said processing structure further executing at least one application to facilitate user interaction with said touch surface. - View Dependent Claims (28, 29, 30, 31, 32, 33)
