Abstract
Laser diode mode techniques are described. In one or more implementations, one or more laser diodes of a computing device are caused to operate below a lasing threshold to illuminate at least part of a physical surroundings of the computing device. One or more images of the illuminated physical surroundings are captured by a camera of the computing device and one or more inputs are recognized from the captured one or more images for interaction with a user interface displayed by the computing device.
