摘要： 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.
