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.

First claim

1 - 17 . (canceled)

18 . A luminaire comprising:
a communication module configured to receive a signal from an external device, the signal indicating a direction of a gaze of a user; an illumination source; and a controller configured to control the illumination source based upon the signal.

19 . The luminaire of claim 18 , further comprising a sensor configured to determine the gaze of the user.

20 . The luminaire of claim 18 , wherein the illumination source comprises an organic light emitting device.

21 . The luminaire of claim 18 , wherein the external device is a mobile computing device.

22 . The luminaire of claim 18 , wherein the controller is further configured to control the illumination source based upon a second signal received from a second external device.

23 . The luminaire of claim 18 , wherein the communication module is in wireless communication with the external device.

24 . The luminaire of claim 18 , 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.

25 . The luminaire of claim 18 , wherein the illumination source comprises a plurality of illumination sources.

26 . The luminaire of claim 18 , wherein the illumination source is transparent, flexible, or both transparent and flexible.

27 . A device comprising:
a gaze direction sensor configured to determine a gaze direction of a user; and a controller configured to control an external illumination source based upon the gaze direction; wherein the external illumination source is physically separate from the device.

28 . The device of claim 27 , wherein the device is a portable computing device.

29 . The device of claim 27 , wherein the gaze direction sensor comprises a camera.

30 . The device of claim 27 further comprising a wireless communication module configured to provide a control signal from the controller to the external illumination source.

31 . The device of claim 27 , wherein the external illumination source comprises a plurality of illumination sources.

32 - 40 . (canceled)

41 . A system comprising:
a local illumination source; a general room illumination source; a light sensor configured to measure a level of illumination in a region; and a controller configured to receive a signal from the light sensor, and to control at least one of the local illumination source and the general room illumination source based upon the signal, to produce a selected illumination level in the region.

42 . The system of claim 41 , wherein the light sensor is physically separate from the local illumination source and from the general room illumination source.

43 . The system of claim 41 , wherein the light sensor consists essentially of a solar cell, a wireless transmitter, and circuitry configured to provide a level of detected illumination via the wireless transmitter.

44 . The system of claim 41 , wherein the controller is configured to adjust the general room illumination source such that, when the local illumination source is on, the general illumination source is operated at a level that is not more than 50% of the illumination intensity at which it is operated when the local illumination source is off.

45 . The system of claim 41 , wherein the controller is configured to adjust the general room illumination source such that, when the local illumination source is on, the energy consumption of the overall system is less than 50% of the energy consumption of the overall system compared to when the local illumination source is off.

46 . The system of claim 41 , wherein the controller is configured to adjust the general room illumination source such that, when the local illumination source is on, the energy consumption of the overall system is less than 30% of the energy consumption of the overall system compared to when the local illumination source is off.
