MOTION AND GESTURE RECOGNITION BY PASSIVE SINGLE PIXEL THERMAL SENSOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for recognizing a gesture made by a warm object.SOLUTION: The system includes a thermal sensor 102 configured to generate a low frequency or direct current signal upon receiving thermal energy. A spatially modulating optic 104 is disposed between the thermal sensor 102 and the warm object. The optic 104 is configured to modulate the thermal energy received by the thermal sensor 102 as a function of an orientation of the warm object with respect to the thermal sensor 102. An electronics unit 106 in communication with the thermal sensor 102 includes a memory and a processor. The processor is configured by the memory to detect change in the thermal sensor signal and recognize a characteristic of the thermal sensor signal.
