Abstract
In some embodiments, eye tracking is used on an AR or VR display system to determine if a user of the display system is blinking or otherwise cannot see. In response, current drain or power usage of a display associated with the display system may be reduced, for example, by dimming or turning off a light source associated with the display, or by configuring a graphics driver to skip a designated number of frames or reduce a refresh rate for a designated period of time.
Claims20
A display system with reduced power use, comprising:
- an inward-facing sensor;
- a display;
- and
- processing electronics in communication with the inward-facing sensor and the display, the processing electronics configured to:
- detect a change in a user's eye status using the inward facing sensor, and
- reduce a current drain of the display system based on when the change in the user's eye status is detected.
