TOUCH SENSOR AND TOUCH SYSTEM INCLUDING THE SAME
First Claim
1. A touch sensor for a touch system, said touch sensor comprising:
- a housing having a light sensing window, a light blocking section, and a reference window, the light sensing window and the reference window configured to allow light to pass therethrough, the light blocking section configured to prohibit light from passing therethrough;
a rotating assembly disposed within the housing; and
a light sensor;
wherein the rotating assembly is configured to transmit light received from the light sensing window and the reference window to the light sensor, and the light sensor is configured to output a signal that is utilized to identify an angular location of a touch.
