Abstract: A touch system includes a touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different locations and having overlapping fields of view. A digital signal processor is associated with each camera. The digital signal processors process pixel data acquired by selected pixel subsets of the at least two digital cameras to generate pointer characteristic data when a pointer exists in the acquired images. The pointer characteristic data identifies edges of the pointer. A master digital signal processor triangulates the edge information in the pointer characteristic data to determine a bounding area that represents a pointer perimeter.

Abstract: A system for detecting contact on a display is provided. The system comprises a planar medium associated with the display and includes at least one edge facet and opposing surfaces. The system also includes one or more optical sources operatively coupled to the at least one edge facet for transmitting an optical signal into the planar medium such that the transmitted optical signal is totally internally reflected between the at least one edge facet and opposing surfaces. An optical sensing device is positioned to substantially face at least a portion of the edge facet and adapted to detect at least one object contacting a first surface of the opposing surfaces. The optical sensing device is operative to detect a portion of the optical signal emitted from the first surface at a location corresponding to the object contacting the first surface.

Abstract: A passive touch system includes a passive touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different locations and have overlapping fields of view. A processor receives and processes images acquired by the at least two cameras to detect the existence of a pointer therein and to determine the location of the pointer relative to the touch surface. Actual pointer contact with the touch surface and pointer hover above the touch surface can be determined.

Abstract: A video conferencing display device a display panel, at least one imaging device and processing structure. The at least one imaging device has a field of view aimed at an inner surface of the display panel and captures images through the display panel such that when a user is positioned adjacent an outer surface of the display panel, the user appears in the captured images. The processing structure communicates with the at least one imaging device and processes the captured images to create a direct eye image for transmission to a remote device over a network.
