US 11,906,732 B2 · Head-mounted display systems with power saving functionality

Abstract

Head-mounted display systems with power saving functionality are disclosed. The systems can include a frame configured to be supported on the head of the user. The systems can also include a head-mounted display disposed on the frame, one or more sensors, and processing electronics in communication with the display and the one or more sensors. In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame is in a certain position (e.g., upside-down or on top of the head of the user). In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame has been stationary for at least a threshold period of time.

Dependent claims

A display system, comprising:

a frame configured to be supported on a head of a user;
a display disposed on the frame, the display configured to project light into an eye of the user to display augmented reality image content to a vision field of the user;
one or more sensors comprising an inward-facing imaging system configured to sense one or more facial features of the user;
and
processing electronics in communication with the display and the one or more sensors, the processing electronics configured to:
determine whether the frame has been removed from the head of the user by analyzing images received from the inward-facing imaging system to identify one or more periocular features of the user, wherein the frame has been removed from the head of the user if the one or more periocular features are identified in a first one of the images and not identified in a second one of the images;
and
cause the display system to reduce power of one or more components of the display system based at least in part on the determination that the frame has been removed from the head of the user.

A display system, comprising:

a frame configured to be supported on a head of the user;
a display disposed on the frame, the display configured to project light into an eye of the user to display augmented reality image content to a vision field of the user;
one or more pressure sensors configured to sense pressure exerted by a portion of the user's head on the frame;
and
processing electronics in communication with the display and the one or more pressure sensors, the processing electronics configured to:
analyze sensed pressures via the one or more pressure sensors to indicate whether the frame has been removed from the user's head, wherein the frame has been removed from the user's head if a first one of the sensed pressures indicates contact with the user's head and a second one of sensed pressures does not indicate contact with the user's head;
and
cause the display system to reduce power of one or more components of the display system based at least in part on the determination that the frame has been removed from the user's head.
