Abstract
A head-mounted display system includes a near-eye display configured to present images to a user's eye, one or more side shields that are configured to fill gaps between the user's face and peripheries of the near-eye display and are dimmable using an electrical control signal, and a controller configured to control dimming of the near-eye display and/or the one or more side shields based at least in part on the luminance and/or spectrum of ambient light, without causing a noticeable change of perceived brightness and/or color temperature by the user's eye.
Claims20
A head-mounted display system comprising:
- a near-eye display configured to present images to a user's eye;
- one or more side shields configured to fill gaps between the user's face and peripheries of the near-eye display, wherein the one or more side shields are at least partially transparent to visible light and are dimmable using an electrical control signal;
- and
- a controller configured to control dimming of the near-eye display and the one or more side shields.
A processor-implemented method comprising:
- obtaining a luminance and/or a spectrum of ambient light of a head-mounted display (HMD) system using one or more ambient light sensors;
- gradually dimming a near-eye display of the HMD system without causing a noticeable change of perceived brightness by a user's eye;
- and
- based at least in part on the luminance and/or the spectrum of the ambient light of the HMD system, changing a transmissivity of one or more side shields that are dimmable and are configured to fill gaps between the user's face and peripheries of the near-eye display.
