Zusammenfassung:An interactive input system comprises at least one light source configured for emitting radiation into a region of interest, a bezel at least partially surrounding the region of interest and having a surface in the field of view of the at least one imaging device, where the surface absorbs the emitted radiation and at least one imaging device having a field of view looking through a filter and into the region of interest and capturing image frames. The filter has a passband comprising a wavelength of the emitted radiation.
