Pressure-sensing touch system utilizing total-internal reflection

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