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.
Claims17
A visible light communication method, comprising:
- obtaining location information, by a receiver, indicating a location of the receiver;
- obtaining a first ID, by the receiver, identifying an area in which a receiver is present by referring to a table in a first server showing correspondence between the first ID and the location information;
- obtaining a second ID, by the receiver, through visible light communication with a light source in the identified area by the first ID;
- generating a third ID, by the receiver, by combining the first ID and the second ID;
- and
- obtaining, by the receiver, information from a second server using the third ID.
A visible light communication method, comprising:
- obtaining a first ID, from a sensor included in a receiver, indicating a physical orientation of the receiver;
- obtaining a second ID by the receiver through visible light communication with a light source;
- generating a third ID, by the receiver, by combining the first ID and the second ID;
- and
- obtaining, by the receiver, information from a server using the third ID.
A visible light communication method, comprising:
- obtaining a first ID indicating a user attribute previously stored in a receiver;
- obtaining a second ID by the receiver through visible light communication with a light source;
- generating a third ID, by the receiver, by combining the first ID and the second ID;
- and
- obtaining, by the receiver, information from a server using the third ID.
A receiver which receives a signal through visible light communication, the receiver comprising:
- a location information obtainer configured to obtain location information indicating a location of the receiver;
- a first ID obtainer configured to obtain a first ID identifying an area in which the receiver is present by referring to a table in a first server showing correspondence between the first ID and the location information;
- a second ID obtainer configured to obtain a second ID through the visible light communication in the identified area;
- a third ID generator configured to generate a third ID by combining the first ID and the second ID;
- and
- an information obtainer configured to obtain information from a second server using the third ID.
