First Claim
Patent Images
1. An optical touch-sensitive device comprising:
- a touch-sensitive surface that includes an active area over which touch events are detectable, wherein the touch-sensitive surface has a top surface that includes tactile surface features;
emitters and detectors arranged along a periphery of the touch-sensitive surface, the emitters producing optical beams that travel across the touch-sensitive surface to the detectors, wherein touches in the active area of the touch-sensitive surface disturb the optical beams, the touch-sensitive device determining touch events based on the disturbed optical beams.
