Patent Images
1. An interactive input system comprising:
- at least two imaging devices associated with a region of interest, said at least two imaging devices acquiring images of said region of interest from different locations and having overlapping fields of view;
at least one receiver operable to receive data output by an active pointer when said pointer is both within and outside the fields of view of said imaging devices; and
processor structure processing data acquired by said at least two imaging devices and said at least one receiver to detect the existence of an active pointer and to determine the location of said pointer within said region of interest.

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.
