Abstract

Systems, devices, and techniques are provided for operating a display and/or an illumination source based upon the direction of a user'"'"'s gaze and/or a desired illumination level in a monitored area. One or more elements may be controlled with sensor input and application lighting preferences. For example, when a user receives a video call, light may be activated to illuminate their face. When the user is looking at the display, the display will be at the brightness necessary for the lighting conditions. When the user looks away from the screen, the screen may dim further and the lighting elements for the desk can brighten. Similarly, embodiments may adjust the lighting in a monitored location based upon lighting levels identified in other areas.

Claims

1. A system comprising:

a display;

an illumination source;

a gaze direction sensor; and

at least one controller in communication with the display and the illumination source, the controller configured to control each of the display and the illumination source based upon a signal received from the gaze direction sensor.

2. The system of claim 1, wherein the at least one controller is configured to control the display at a different rate of change than the illumination source.

3. The system of claim 1, wherein each of the display and the illumination source is configured to change state at a different rate, in response to an instruction from the controller.

4. The system of claim 1, wherein the illumination source comprises an organic light emitting device.

5. The system of claim 1, further comprising a first electronic device and a second electronic device, wherein the first electronic device comprises the display and the gaze direction sensor, and the second electronic device comprises the illumination source and the controller.

6. The system of claim 1, wherein the display, the illumination source, the gaze direction sensor, and the controller are disposed in a single physical device.

7. The system of claim 1, wherein each of the display, the illumination source, the gaze direction sensor, and the controller is a physically separate device.

8. The system of claim 1, wherein the at least one controller is in wireless communication with at least one selected from the group of:

the display, the illumination device, and the gaze direction sensor.

9. The system of claim 1, further comprising a general-purpose computer and a lamp, wherein the general-purpose computer comprises the display and the gaze direction sensor, and the lamp comprises the illumination source.

10. The system of claim 1, further comprising a second illumination device controllable by the at least one controller.

11. The system of claim 1, further comprising a mobile second computing device, configured to determine a gaze of a user, and wherein the at least one controller is further configured to control the illumination source in response to a second signal from the second computing device.

12. The system of claim 1, wherein the gaze direction sensor comprises a camera.

13. The system of claim 1, wherein the illumination source is color-tunable, and wherein the controller is configured to control the color of light emitted by the illumination source in response to the signal.

14. The system of claim 1, wherein the at least one controller is configured to control the color temperature of a white point of the display in response to the signal.

15. A system comprising:

a display;

a color-tunable illumination source;

a gaze direction sensor; and

at least one controller in communication with the display and the illumination source, the controller configured to control a color of light emitted by the illumination source based upon a signal received from the gaze direction sensor.

16. A system comprising:

a display;

an illumination source;

a gaze direction sensor; and

at least one controller in communication with the display and the illumination source, the controller configured to control a color temperature of a white point of the display based upon a signal received from the gaze direction sensor.
