Scanning FTIR: Unobtrusive Optoelectronic Multi-Touch Sensing through Waveguide Transmissivity Imaging

Jon Moeller (Texas A&M University)

Abstract

We describe a new method of multi-touch sensing which can be unobtrusively added to existing displays. By coupling optoelectronics to the edge of a planar waveguide, we overcome prior disadvantages of optoelectronic touch sensing. Our approach allows for a completely transparent touch surface and easy integration with existing LCD displays.
