1. A device to detect a gesture made by an object in touch-less communication, the device comprising:
- two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors configured to measure light intensity at the respective surface location; and
a processor configured to detect the gesture based on a comparison of the light intensity measured at each of the respective surface locations at two or more time instants or measurement cycles.

15. A method of detecting a gesture made by an object in touch-less communication with a device, the method comprising:
-
measuring, using two or more ambient light sensors arranged at respective surface locations of the device, light intensity at the respective surface locations; comparing, using a processor, the light intensity at each of the respective surface locations at two or more time instants or measurement cycles to identify one or more characteristics of the gesture; and detecting the gesture using the processor, based on the one or more characteristics. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
