1. A method comprising:
- causing one or more laser diodes of a computing device to operate below a lasing threshold to illuminate at least part of a physical surroundings of the computing device;
capturing one or more images of the illuminated physical surroundings by a camera of the computing device;
recognizing, from the captured one or more images, one or more inputs for interaction with a user interface displayed by the computing device; and
causing the one or more laser diodes of the computing device to operate above the lasing threshold to output coherent light to project a pattern into the physical surroundings.

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.

9. A method implemented by a computing device, the method comprising:
-
operating one or more laser diodes in a spontaneous mode to illuminate at least part of a physical surroundings of the computing device using incoherent light in an amount suitable to recognize one or more inputs for interaction with a user interface using a camera of the computing device; and operating the one or more laser diodes in a coherent mode to project a pattern using coherent light into the physical surroundings that is usable to determine a distance between the one or more laser diodes and one or more objects in the physical surroundings. - View Dependent Claims (10, 11, 12)
