Interactive large scale touch surface system

Interactive large scale touch surface system

A touch system (100) comprises a large scale touch surface (102) on which an image is presented and at least two imaging devices (C0 to C ''3) looking across the touch surface and having overlapping fields of view. Processing structure (108, 110) communicates with the imaging devices and p...

Zusammenfassung:A touch system (100) comprises a large scale touch surface (102) on which an image is presented and at least two imaging devices (C0 to C ''3) looking across the touch surface and having overlapping fields of view. Processing structure (108, 110) 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.
