TOUCH-LESS USER INTERFACE USING AMBIENT LIGHT SENSORS
First Claim
1. A device to detect a gesture by an object in touch-less communication, the device comprising:
- two or more ambient light sensors arranged at respective surface locations of the device and configured to measure light intensity at the respective surface locations;
two or more infrared illuminators configured to emit infrared light;
two or more infrared receivers configured to measure reflectance resulting from the infrared light encountering the object; and
a processor configured to determine the gesture based on the light intensity from each of the two or more ambient light sensors and the reflectance from the two or more infrared receivers.
