Abstract: An interactive input system includes at least one image sensor capturing image frames of a region of interest; at least one light source emitting illumination into the region of interest; a bezel at least partially surrounding the region of interest, the bezel comprising at least one multi-angle reflector reflecting the illumination emitted from the light source towards the at least one image sensor; and processing structure in communication with the at least one image sensor processing captured image frames for locating a pointer positioned in proximity with the regin of interest. A method of generating image frames is also provided.

Abstract: A plug-and-play device comprises a first plug-and-play interface for establishing a connection with a first computing device and a second plug-and-play interface for establishing a connection with a second computing device. Storage stores code that is automatically executed by the second computing device when the plug-and-play device is connected to the second computing device via the second plug-and-play interface. The code when executed by the second computing device initiates a screen display data exchange between the first and second computing devices through the plug-and-play device. A controller controls the first plug-and-play interface, the second plug-and-play interface and the storage.

Abstract: An interactive input system comprises at least two imaging devices associated with a region of interest. The at least two imaging devices acquire images of the region of interest from different locations and have overlapping fields of view. At least one receiver is operable to receive data output by an active pointer when the pointer is both within and outside the fields of view of the imaging devices. Processor structure processes data acquired by the at least two imaging devices and the at least one receiver to detect the existence of an active pointer and to determine the location of the pointer within the region of interest.
