Abstract

Aspects of the disclosure relate to a light source based location and operation system. A computing device may detect an encoded light signal containing an identifier from a light source at a location. The encoded light signal can be decoded to obtain the identifier, and a request for information based on the identifier can be transmitted in response to decoding the identifier. Information associated with the identifier may be received in response to the request for information including location information corresponding to the location of the light source. The location information may be used to provide additional information to the user or enable a user to control devices based on the location information.

First claim

I claim:

1. A method comprising:
detecting, by a computing device at a location, an encoded light signal from a light source at the location, wherein the encoded light signal indicates the location;
transmitting, by the computing device, a request for a list of content consumption devices at the location indicated by the encoded light signal;
receiving, by the computing device, the list of content consumption devices;
transmitting, by the computing device, a selection of a content consumption device from the list of content consumption devices; and
controlling, by the computing device, a selected content consumption device from the list of content consumption devices.

2. The method of claim 1 , further comprising detecting, by the computing device at the location, the encoded light signal from a plurality of light sources at the location.

3. The method of claim 2 , wherein the detecting, by the computing device at the location, the encoded light signal from the plurality of light sources at the location comprises detecting the encoded light signal from one or more display devices.

4. The method of claim 3 , wherein the detecting the encoded light signal from the plurality of light sources comprises detecting the encoded light signal from at least part of a backlight of the one or more display devices.

5. The method of claim 1 , further comprising:
decoding the encoded light signal to obtain an identifier associated with the light source at the location; and
registering the identifier in a database, wherein the database comprises information associated with the light source.

6. The method of claim 1 , wherein the controlling, by the computing device, the selected content consumption device is in response to:
transmitting, by the computing device and to a second computing device remote from the computing device, a connection request to establish a communication channel between the computing device and the selected content consumption device.

7. The method of claim 6 , wherein the connection request comprises an identifier of the selected content consumption device.

8. The method of claim 2 , further comprising configuring the plurality of light sources to emit light signals having a same identifier encoded therein.

9. A method comprising:
receiving, by a first computing device and from a second computing device, information comprising an identifier of a light source whose light was detected by the second computing device;
determining, by the first computing device and based on the identifier of the light source, a location of the light source;
in response to the determining the location of the light source,
transmitting, by the first computing device and to the second computing device, a list of one or more content consumption devices at the location of the light source;
receiving, by the first computing device and from the second computing device, a selection of a selected content consumption device from the list of one or more content consumption devices; and
in response to the receiving the selection, establishing, by the first computing device, a communication channel between the selected content consumption device and the second computing device.

10. The method of claim 9 , wherein the determining the location of the light source further comprises determining that the light source is a display device.

11. The method of claim 9 , wherein the transmitting the list of one or more content consumption devices at the location of the light source is based on:
determining, by the first computing device, a usage history associated with one or more content consumption devices at the location of the light source.

12. The method of claim 9 , further comprising:
receiving, by the first computing device and from a third computing device, an indication that the third computing device has detected light from the light source, and in response, adding, by the first computing device, the third computing device to the list of one or more content consumption devices at the location of the light source.

13. A method comprising:
detecting, by a computing device at a location, an encoded light signal from a light source at the location, wherein the encoded light signal indicates the location;
transmitting, by the computing device, a request for a list of controllable devices at the location indicated by the encoded light signal;
receiving, by the computing device, the list of controllable devices;
selecting, by the computing device, a controllable device from the list of controllable devices to control based on a determination of a usage history; and
controlling, by the computing device, the selected controllable device from the list of controllable devices.

14. The method of claim 13 , further comprising detecting, by the computing device at the location, the encoded light signal from a plurality of light sources at the location.

15. The method of claim 14 , wherein the detecting, by the computing device at the location, the encoded light signal from the plurality of the light sources at the location comprises detecting the encoded light signal from one or more display devices.

16. The method of claim 15 , further comprising detecting, by the computing device at the location, the encoded light signal from the plurality of the light sources, wherein the plurality of the light sources comprise at least part of a backlight of the one or more display devices.

17. The method of claim 13 , further comprising:
in response to the selecting the controllable device, transmitting, by the computing device to a second computing device remote from the computing device, a connection request to establish a communication channel between the computing device and the selected controllable device.

18. The method of claim 17 , wherein the connection request comprises an identifier of the selected controllable device.

19. The method of claim 13 , wherein the determination of the usage history further comprises determining, by the computing device, a default controllable device.

20. The method of claim 13 , wherein the determination of the usage history is further based on a determination of viewing times of the controllable devices.
