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: An example computing device includes: a display to display a color calibration pattern; a touchpad to receive input for the computing device, the touchpad having a reflective layer to reflect the color calibration pattern; a color sensor to detect the reflected color calibration pattern from the touchpad; a processor interconnected with the color sensor and the display, the processor to calibrate a color output of the display based on the color calibration pattern detected at the color sensor.
