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.
Claims10
A head-mounted display system comprising:
- an inward facing eye tracking sensor;
- a display including a light source;
- and
- processing electronics configured to operate the head mounted display system in at least a first display mode and a second display mode, wherein the processing electronics are configured to:
- operate the display in the first display mode in which the light source is energized to present visual content to a user;
- based on eye tracking data generated by the inward facing eye tracking sensor indicating that the user is unable to visually perceive the visual content, transition the display from the first display mode to the second display mode in which the light source is turned off while the processing electronics remain powered;
- and
- in response to the eye tracking data indicating that the user is able to visually perceive the visual content, transition the display from the second display mode back to the first display mode without reinitializing the display.
