Electronic device with a display for low light conditions
Operating an outward-facing display device for low light conditions may include receiving information indicative of ambient lighting conditions for the display device's environment; in accordance with a determination that the ambient lighting conditions do not satisfy a brightness criterion, determining a set of pixels in the outward-facing display device corresponding to an area of interest in the environment; and driving the set of pixels at a particular brightness to improve lighting in the area of interest.
1 . A method, comprising:
receiving, by a head-mounted device, information indicative of ambient lighting conditions in a physical environment, wherein the head-mounted device comprises a plurality of outward-facing illuminators directed toward the physical environment and a user-tracking sensor; and
in accordance with a determination that the ambient lighting conditions in the physical environment fail satisfy a brightness criterion:
determining an area of interest in the physical environment in accordance with sensor data from the user-tracking sensor,
identifying a first outward-facing illuminator of the plurality of outward-facing illuminators corresponding to the area of interest, and
activating the first outward-facing illuminator to illuminate the area of interest.
2 . The method of claim 1 , further comprising:
determining a target light color corresponding to the area of interest in the physical environment; and
activating the first outward-facing illuminator to illuminate in accordance with the target light color.
3 . The method of claim 1 , wherein the user-tracking sensor comprises a gaze tracking sensor, and wherein the area of interest is determined based on a direction of the gaze.
4 . The method of claim 1 , wherein the area of interest corresponds to an input region of the physical environment, wherein the input region comprises a gesture-based user interface.
5 . The method of claim 1 , wherein receiving the information indicative of the ambient lighting conditions comprises capturing, by an outward-facing camera, an image of the physical environment.
6 . The method of claim 5 , wherein the outward-facing camera is arranged facing in a same direction as one or more of the plurality of outward-facing illuminators.
7 . A non-transitory computer readable medium comprising computer readable code executable by one or more processors to:
receive, by a head-mounted device, information indicative of ambient lighting conditions in a physical environment, wherein the head-mounted device comprises a plurality of outward-facing illuminators directed toward the physical environment and a user-tracking sensor; and
in accordance with a determination that the ambient lighting conditions in the physical environment fail satisfy a brightness criterion:
determine an area of interest in the physical environment in accordance with sensor data from the user-tracking sensor,
identify a first outward-facing illuminator of the plurality of outward-facing illuminators corresponding to the area of interest, and
activate the first outward-facing illuminator to illuminate the area of interest.
8 . The non-transitory computer readable medium of claim 7 , further comprising computer readable code to:
determine a target light color corresponding to the area of interest in the physical environment; and
activate the first outward-facing illuminator to illuminate in accordance with the target light color.
9 . The non-transitory computer readable medium of claim 7 , wherein the user-tracking sensor comprises a gaze tracking sensor, and wherein the area of interest is determined based on a direction of the gaze.
10 . The non-transitory computer readable medium of claim 7 , wherein the area of interest corresponds to an input region of the physical environment, wherein the input region comprises a gesture-based user interface.
11 . The non-transitory computer readable medium of claim 7 , wherein the computer readable code to receive the information indicative of the ambient lighting conditions comprises computer readable code to cause an outward-facing camera to capture an image of the physical environment.
12 . The non-transitory computer readable medium of claim 11 , wherein the outward-facing camera is arranged facing in a same direction as one or more of the plurality of outward-facing illuminators.
13 . A system comprising:
one or more processors; and
one or more computer readable media comprising computer readable code executable by the one or more processors to:
receive, by a head-mounted device, information indicative of ambient lighting conditions in a physical environment, wherein the head-mounted device comprises an plurality of outward-facing illuminators directed toward the physical environment and a user-tracking sensor; and
in accordance with a determination that the ambient lighting conditions in the physical environment fail satisfy a brightness criterion:
determine an area of interest in the physical environment in accordance with sensor data from the user-tracking sensor,
identify a first outward-facing illuminator of the plurality of outward-facing illuminators corresponding to the area of interest, and
activate the first outward-facing illuminator to illuminate the area of interest.
14 . The system of claim 13 , further comprising computer readable code to:
determine a target light color corresponding to the area of interest in the physical environment; and
activate the first outward-facing illuminator to illuminate in accordance with the target light color.
15 . The system of claim 13 , wherein the user-tracking sensor comprises a gaze tracking sensor, and wherein the area of interest is determined based on a direction of the gaze.
16 . The system of claim 13 , wherein the area of interest corresponds to an input region of the physical environment, wherein the input region comprises a gesture-based user interface.
17 . The system of claim 13 , wherein the computer readable code to receive the information indicative of the ambient lighting conditions comprises computer readable code to cause an outward-facing camera to capture an image of the physical environment.
