Multiple pointer ambiguity and occlusion resolution

Multiple pointer ambiguity and occlusion resolution

A method of resolving ambiguities between at least two pointers in an interactive input system comprises capturing images of a region of interest, processing image data to determine a plurality of potential targets for the at least two pointers within the region of interest and a current target loca...

Zusammenfassung:A method of resolving ambiguities between at least two pointers in an interactive input system comprises capturing images of a region of interest, processing image data to determine a plurality of potential targets for the at least two pointers within the region of interest and a current target location for each potential target, the plurality of potential targets comprising real and phantom targets, tracking each potential target within the region of interest and calculating a predicted target location for each potential target and determining a pointer path associated at least with each real target.
