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.

Interactive input system

An interactive input system comprises a pointer input region; and a multi-angle reflecting structure located along a single side of the pointer input region and operable to reflect radiation from a pointer within the pointer input region from at least two surface locations of the multi-angle reflecting structure, wherein the at least two surface locations each have different respective angles. An imaging system is operable to capture within at least a portion of the pointer input region images of the reflected radiation located within a field of view of the imaging system. Processing structure is provided for determining the location of the pointer relative to the pointer input region based on the at least one image.

Interactive input system with multi-angle reflector

A method of inhibiting a subject's eyes from being exposed to projected light when the subject is positioned in front of a background on which an image is displayed comprises capturing at least one image of the background including the displayed image, processing the captured image to detect the existence of the subject and to locate generally the subject and masking image data used by the projector to project the image corresponding to a region that encompasses at least the subject's eyes.
