Pressure sensing touch systems and methods

摘要: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a event based on pressure applied at location. The system includes light-source detector operably disposed adjacent respective input output edges waveguide either in form transparent sheet or as formed sheet. Pressure location that gives rise to causes bend flex. bending change optical paths light traveling by FTIR waveguide. This turn distribution change. changes detected used determine whether occurred, well time-evolution event. can include polarization caused birefringence induced Various configurations
