Abstract

A visible light communication method includes: obtaining a first ID identifying an area in which a receiver is present; obtaining a second ID by the receiver through visible light communication; and obtaining information corresponding to a third ID which is a combination of the first ID and the second ID. For example, in the obtaining of a first ID, the first ID may be obtained by referring to a table showing correspondence between the first ID and location information obtained by the receiver and indicating a location of the receiver.

Claims

1. A visible light communication method comprising:

obtaining a first ID identifying an area in which a receiver is present;

obtaining a second ID by the receiver through visible light communication in the identified area; and

obtaining, by the receiver, information corresponding to a third ID which is a combination of the first ID and the second ID.

2. The visible light communication method according to claim 1,

wherein in the obtaining of a first ID, the first ID is obtained by referring to a table showing correspondence between the first ID and location information obtained by the receiver and indicating a location of the receiver.

3. The visible light communication method according to claim 2,

wherein the location information is information indicating the location of the receiver identified by a Global Positioning System (GPS) installed on the receiver.

4. The visible light communication method according to claim 2,

wherein the location information is information indicating a wireless LAN access point accessible by the receiver.

5. The visible light communication method according to claim 2,

wherein the location information is information obtained by the receiver and indicating a store in which the receiver is present.

11. The visible light communication method according to claim 1, further comprising:

performing processing of receiving a request to distribute information from a requester;

distributing, as the information corresponding to the third ID, the information subject to the request from the requester; and

performing information processing for charging the requester according to the distribution of the information.

12. An identification signal which is generated by the visible light communication method according to claim 1 and comprises the first ID and the second ID.

14. A non-transitory computer-readable recording medium having recorded thereon a program for causing a computer to execute the visible light communication method according to claim 1.

6. A visible light communication method comprising:

obtaining a first ID indicating an orientation of a receiver;

obtaining a second ID by the receiver through visible light communication; and

obtaining, by the receiver, information corresponding to a third ID which is a combination of the first ID and the second ID.

7. The visible light communication method according to claim 6,

wherein the receiver includes a first camera and a second camera, and

in the obtaining of a second ID, one of the first camera and the second camera is selected according to the orientation of the receiver and used to obtain the second ID.

8. The visible light communication method according to claim 6,

wherein in the obtaining of a first ID, the first ID that indicates a tilt of the receiver is obtained.

9. The visible light communication method according to claim 8,

wherein in the obtaining of a first ID, the first ID is obtained by referring to a table showing correspondence between the tilt of the receiver and the first ID.

10. A visible light communication method comprising:

obtaining a first ID indicating a user attribute of a receiver;

obtaining a second ID by the receiver through visible light communication; and

obtaining, by the receiver, information corresponding to a third ID which is a combination of the first ID and the second ID.

13. A receiver which receives a signal through visible light communication, the receiver comprising:

a first ID obtaining unit configured to obtain a first ID identifying an area in which the receiver is present;

a second ID unit configured to obtain a second ID through the visible light communication in the identified area; and

an information obtaining unit configured to obtain information corresponding to a third ID which is a combination of the first ID and the second ID.
