Abstract: A device and method to facilitate display navigation by touch-less gesture are described. The device includes two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors measuring light intensity at the respective surface location. The device also includes a processor to detect a gesture as a detected gesture performed by an object in touch-less communication with the device and output a signal corresponding with the detected gesture, and a navigation gesture library to store two or more gestures and corresponding two or more signals, wherein the processor accesses the navigation gesture library when the device is not executing an application with an associated application gesture library.
