摘要： An illumination structure for an interactive input system having a display surface and a light source for backlighting the display surface is provided. The illumination structure includes at least one redirection structure positioned with respect to the display surface to receive excess light produced by the light source and to redirect the excess light generally across the display surface for backlighting one or more pointers. A method is provided for determining the location of at least one pointer in an interactive input system. The method includes capturing images generally across a display surface of a region of interest and a reflection of the region of interest; examining the images to determine at least one first potential target location for at least one pointer that is within the region of interest; analyzing the at least one first potential target location to resolve at least one first true target location associated with the at least one pointer; and calculating a first location for the at least one pointer corresponding to the at least one first true target location.

摘要： A passive touch system includes a touch surface and at least one source of backlight illumination projecting backlighting across the touch surface. At least two image sensors are associated with the touch surface and acquire images of the touch surface from different locations. A digital signal processor is associated with each image sensor. The digital signal processors select pixel subsets of images acquired by the image sensors and process pixel data acquired by the selected pixel subsets to generate pointer characteristic data when a pointer exists in the acquired images. A master digital signal processor in communication with the digital signal processors triangulates the pointer characteristic data to determine the location of the pointer relative to the touch surface.

摘要： A touch system comprises a touch surface and at least one camera acquiring images of the touch surface. A pointer contact data generator generates pointer position data in response to pointer contact with the touch surface, the pointer position data representing where on the touch surface pointer contact is made. A processor communicates with the at least one camera and the pointer contact data generator. The processor analyzes acquired images to determine the type of pointer used to contact the touch surface, and processes the pointer position data in accordance with the determined type of pointer. In the preferred embodiment the processor distinguishes between pointer tip touch surface contacts, pointer backend touch surface contacts and finger touch surface contacts. A writing function is invoked in response to pointer tip touch surface contacts. An erase function is invoked in response to pointer backend touch surface contacts. Mouse events are generated in response to finger touch surface contacts.

摘要： An apparatus for detecting a pointer within a region of interest includes at least one pair of imaging devices. The imaging devices have overlapping fields of view encompassing the region of interest. At least one light source provides illumination across the region of interest and is within the field of view of at least one of the imaging device. A filter is associated with the at least one imaging device whose field of view sees the light source. The filter blocks light projected by the light source to inhibit the imaging device from being blinded by the projected light.
