1. A device to control measurements of light intensity, 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 the light intensity at the respective surface location; and
a processor configured to control operation of the two or more ambient light sensors according to a sampling pattern wherein the two or more ambient light sensors measure light intensity simultaneously or in sequence with one another, wherein the processor is further configured to detect a touch-less gesture made by an object in touch-less communication with the device based on the light intensity measurements, wherein the touch-less gesture is detected in three dimensions between an ambient light source and the two or more ambient light sensors.
