Abstract
A light-based touch sensitive device, including a housing, a surface encased in the housing, a layer of elastic material above the surface, a plurality of light pulse emitters mounted in the housing, that transmit light pulses through the layer, a plurality of light pulse receivers mounted in the housing, that receive the light pulses transmitted through the layer, and a calculating unit, mounted in the housing and connected to the receivers, that determines a location of a pointer that touches the layer and creates an impression in the layer, based on outputs of the receivers.
