Abstract:
A method comprises capturing image frames of an input area using a plurality of imaging devices, each having a field of view encompassing at least a portion of the input area; processing captured image frames to identify a plurality of targets therein; analyzing the identified plurality of targets to determine if the targets represent a plurality of projections of an input object; and if so, identifying a pattern of the projections thereby to identify the input object.
