Abstract
A display system for a head-mounted device comprising a display for displaying information. The display system includes a glance detector comprising a light source, disposed proximate the display, for transmitting light toward an eye of a user of the head-mounted device, a light detector, disposed proximate the light source, for detecting light reflected from the eye of the user and generating a voltage based on the detected light. The display system also includes a processor operably coupled to the display, and the gaze detector and configured to control the display to turn-on the display based on the voltage received from the glance detector.
Claims23
A display system for a head-mounted device comprising:
- a display for displaying information;
- a glance detector disposed proximate the display and comprising:
- a light source for transmitting light toward a pupil of an eye of a user of the head-mounted device, the light source oriented to project light to illuminate an illumination area that at least substantially encompasses the user's pupil when the user is looking at the display;
- and
- a light detector for detecting light reflected from the illumination area and generating a voltage based on the detected light;
- and
- a processor for controlling the display and receiving the voltage from the glance detector, the processor configured to turn-on the display based on the voltage received from the glance detector.
A method of controlling a display system for a head-mounted device, comprising:
- transmitting, utilizing a light source, light toward a pupil of an eye of the user of the head mounted device to illuminate an illumination area that at least substantially encompasses the user's pupil when the user is looking at the display;
- detecting, utilizing a light detector, light reflected from the illumination area;
- determining a voltage based on the detected light;
- controlling a display to turn-on the display based on the determined voltage.
