Abstract
An augmented reality display system can include a partially transparent eyepiece, an ambient light sensor, and an image input device. The image input device can include a light source and a spatial light modulator. The system can also include a controller that determines that no virtual content is being displayed to the user and compares the ambient light to display light to determine if a light source shutoff criterion is satisfied. If the light source shutoff criterion is satisfied, the controller can turn off the light source.
Claims28
An augmented reality display system comprising:
- an eyepiece display configured to be worn by a user, the eyepiece display being at least partially transparent so as to transmit ambient light toward the eye of the user;
- an ambient light sensor configured to detect the ambient light;
- an image input device capable of inputting virtual content into the eyepiece display, the image input device comprising a light source and a spatial light modulator illuminated by the light source;
- and
- a controller,
- wherein the eyepiece display is configured to emit display light, and
- wherein the controller is configured to:
- determine that no virtual content is being displayed to the user;
- compare the ambient light to the display light to determine if a light source shutoff criterion is satisfied, and
- turn off the light source if the light source shutoff criterion is satisfied.
