Abstract: An example computing device includes a photodetector to measure an amount of light incident on a detection surface of the photodetector. The example computing device includes a state sensor to activate the photodetector responsive to the computing device being in a detection state. The example computing device also includes a processor. An example processor identifies, during the detection state, a user gesture based on an output of the photodetector. The user gesture blocks light incident on the detection surface of the photodetector. The example processor also alters an operation of the computing device based on the user gesture.

Abstract: In some examples, the disclosure describes a device that includes a first light sensor to determine a first quantity of light at a first location; a second light sensor to determine a second quantity of light at a second location; a display device to display images; a processor; and a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor to: determine when a difference between the first quantity of light and the second quantity of light device exceeds a threshold quantity, select a light sensor from the first light sensor and the second light sensor based on the first quantity of light received by the first light sensor and the second quantity of light received by the second light sensor, and alter a brightness of the display device based on the selected light sensor.
