An interactive input system with bezel light around an input area provided by optical fiber is described. Two or more cameras have a field of view of at least a portion of the bezel. The optical fiber provides continuous backlight illumination to at least one input object. The optical fiber has at least one nanostructure therein for diffusing light. At least one light source provides a directional light to an end of the optical fiber.
