Abstract

A pressure sensing touch system that utilizes total internal reflection of light is disclosed. The touch system includes a transparent sheet having a surface. At least one light source and at least one detector are operably arranged relative to the transparent sheet respective to transmit light through the sheet and to detect the transmitted light. A touch event at the top surface of the transparent sheet causes light to scatter from the transparent sheet thereby changing the amount of light received at the detector. Since the amount of scattered light generated at the touch event location is a function of the applied pressure at the touch event the change in the detector signal is used to determine the relative amount of applied pressure. Embodiments that include multiple waveguides and channel waveguides as well as forcesensing devices are also disclosed.
