Abstract
A method for resolving ambiguities between at least two pointers in a plurality of input regions defining an input area of an interactive input system. The method includes capturing images of the plurality of input regions, the images captured by a plurality of imaging devices having a field of view of at least a portion of the input area, processing image data from the images to identify a plurality of targets for the at least two pointers within the input area, and analyzing the plurality of targets to resolve a real location associated with each pointer.
