Systems With Supplemental Illumination: abstract simplified (18179899)

• This abstract for appeared for patent application number 18179899 Titled 'Systems With Supplemental Illumination'

Simplified Explanation

The abstract describes a head-mounted device that has a support structure and displays to present images to the user's eyes. It also includes cameras and sensors supported by the device. The cameras are used to track the movement of the user's hands or other objects. In low light conditions, an additional illumination system is activated to provide extra light for the cameras. This can be done by emitting a single beam of light over a specific area or by steering a smaller beam of light across the area. Infrared light-emitting diodes and lasers are used to create infrared light sources for the illumination system.

Original Abstract Submitted

A head-mounted device may have a head-mounted support structure. Displays may present images to eye boxes at the rear of the head-mounted support structure. Cameras and other sensors may be supported by the head-mounted support structure. Tracking cameras may be used to track the movement of a user's hands or other external objects. In dim ambient lighting conditions, a supplemental illumination system may be activated to provide supplemental illumination for the tracking cameras. A single beam of supplemental illumination may be emitted over a given coverage area or a smaller beam of supplemental illumination may be steered across the given coverage area. Light-emitting devices such as infrared light-emitting diodes and infrared lasers may be used to form infrared light sources for the supplemental illumination system.
