An interactive input system (50) comprises imaging devices (70) with different viewpoints and having at least partially overlapping fields of view encompassing a region of interest. At least two of the imaging devices have different focal lengths. Processing structure (70, 54, 56) processes image data acquired by the imaging devices to detect the existence of a pointer and determine the location of the pointer within the region of interest.
