Abstract
This disclosure describes a head-mounted display with a display assembly configured to display content to most or all of a user's field of view. The display assembly can be configured to display content in far-peripheral regions of the user's field of view differently than content upon which a user can focus. For example, spatial resolution, color resolution, refresh rate and intensity (i.e. brightness) can be adjusted to save resources and/or to bring attention to virtual content positioned within a far-peripheral region. In some embodiments, these changes can save processing resources without detracting from the user's overall experience.
Claims17
A wearable display device, comprising:
- a frame including an attachment member configured to secure the wearable display device to a head of a user;
- and
- a display assembly coupled to the frame, the display assembly comprising:
- a main display comprising one or more optical waveguides configured to project an angular representation of virtual content onto an eye of the user, wherein the main display has a first resolution, and wherein the main display is sized to at least partially cover a field of regard of the eye of the user;
- and
- a peripheral display that borders and surrounds the main display and that has a second resolution that is lower than the first resolution, wherein the peripheral display includes a screen-based display that is configured to generate a spatial representation of the virtual content, and wherein the screen-based display of the peripheral display is in physical contact with the one or more optical waveguides of the main display.
A head-mounted display device, comprising:
- a frame including an attachment member configured to secure the head-mounted display device to a head of a user;
- and
- a display assembly coupled to the frame and configured to output virtual content toward an eye of the user, the display assembly comprising:
- a first region having a first resolution, the first region comprising one or more optical waveguides configured to project an angular representation of the virtual content onto the eye of the user, wherein the first region is sized to at least partially cover a field of regard of the eye of the user;
- a second region that at least partially borders and surrounds the first region and having a second resolution lower than the first resolution, wherein the second region includes a screen-based display that is configured to generate a spatial representation of the virtual content;
- and
- a transition region between the first region and the second region having a variable resolution that is higher on a first side of the transition region adjacent to the first region than a second side of the transition region adjacent the second region, wherein the transition region is in physical contact with each of the first region and the second region.
A wearable display device, comprising:
- a frame;
- a projector coupled to the frame;
- and
- a display assembly, comprising:
- a main display coupled to the frame and comprising one or more optical waveguides configured to project an angular representation of virtual content onto an eye of a user, wherein the main display has a first resolution, and wherein the main display is sized to at least partially cover a field of regard of the eye of the user, and
- a peripheral display that at least partially borders and surrounds the main display and that has a second resolution that is lower than the first resolution, wherein the peripheral display includes a screen-based display that is configured to output a spatial representation of the virtual content, wherein the screen-based display of the peripheral display is in physical contact with the one or more optical waveguides of the main display.
