<p>A device and method to detect a gesture by an object in touch-less communication are described. The device includes two or more ambient light sensors arranged at respective surface locations of the device and measuring light intensity at the respective surface locations, two or more infrared illuminators that emit infrared light, and two or more infrared receivers that measure reflectance resulting from the infrared light encountering the object. The device also includes a processor 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.</p> |
