    摘要: A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.

    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 relative to a touch surface includes at least two spaced imaging assemblies having overlapping fields of view encompassing the touch surface. The imaging assemblies see the touch surface in three-dimensions as a perspective view. The imaging assemblies acquire overlapping images from different locations. A processor receives and processes image data generated by at least one of the imaging assemblies to determine the location of the pointer relative to the touch surface.

    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.
