Abstract
A touch sensitive apparatus comprises a top plate configured such that light from the one or more light sources is transmitted within the top plate with total internal reflection; and a base plate within which, light is transmissible. The base plate comprises a plurality of base plate elements optically separated from each other. The top plate and the base plate are configured such that if an external body touches a first surface of the top plate, then light is coupled from a second surface of the top plate into an underlying base plate element for transmission within that base plate element. Each base plate element has one or more detectors for detecting light transmitted within that base plate element. A processor determines information from the detectors relating to touching of the first surface of the top plate. An associated method is also described.
