SYSTEMS, DEVICES, AND METHODS FOR WEARABLE HEADS-UP DISPLAYS WITH HETEROGENEOUS DISPLAY QUALITY
First Claim
1. A wearable heads-up display comprising:
- a support structure that in use is worn on a head of a user;
a projector carried by the support structure;
a processor communicatively coupled to the projector; and
a non-transitory processor-readable storage medium communicatively coupled to the processor, wherein the non-transitory processor-readable storage medium stores processor-executable virtual content control instructions that, when executed by the processor, cause the wearable heads-up display to;
determine a region of interest in a field of view of the user;
project virtual content with a first quality level with respect to a first display parameter in the region of interest; and
project virtual content with a second quality level with respect to the first display parameter outside of the region of interest, wherein the first quality level is higher than the second quality level.

Abstract
Systems, devices, and methods are described for wearable heads-up displays (“WHUDs”) that provide virtual content with heterogeneous display quality. The WHUDs display virtual content with relatively high quality in a region of interest of the user'"'"'s field of view (“FOV”) and with relatively lower quality in regions of the user'"'"'s FOV that are outside of the region of interest. The region of interest may align with a foveal region of the user'"'"'s FOV at which the user'"'"'s visual acuity is maximal. By limiting display quality for peripheral regions of the virtual content at which the typical user is not able to focus, graphical processing power and/or WHUD battery power are conserved. As a result, a smaller battery and/or smaller other components may be used and the form factor of the WHUD may be reduced. A sensor may be employed to determine the region of interest in the user'"'"'s FOV.

12. A method of operating a wearable heads-up display to display virtual content with non-uniform quality, the wearable heads-up display including a projector and the method comprising:
-
determining a region of interest in a field of view of a user of the wearable heads-up display; projecting, by the projector, virtual content with a first quality level with respect to a first display parameter in the region of interest of the field of view of the user; and projecting, by the projector, virtual content with a second quality level with respect to the first display parameter in regions of the field of view of the user that are outside of the region of interest, wherein the first quality level is higher than the second quality level. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
