Gaze detecting heads-up display systems

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.

What is claimed is: 
     
         1 . 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; and 
 a light detector for detecting light reflected from the pupil of the eye of the user 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.
