Communication device

A wireless communication terminal comprising:

• a position information obtainment unit configured to estimate terminal position information which is position information of the wireless communication terminal, using an internal sensor;
• a peripheral apparatus information storage unit configured to store, as unique information corresponding to a peripheral apparatus registered beforehand, at least an apparatus ID, position information, and an identifier of the peripheral apparatus, the identifier indicating whether or not the peripheral apparatus supports optical communication for modulating information as a light emitting pattern and transmitting the modulated information;
• an imaging device that obtains light generated by the peripheral apparatus modulating the information as the light emitting pattern;
• an optical communication information obtainment unit configured to decode the information from the light emitting pattern of the light obtained by the imaging device;
• a server cooperative communication unit configured to notify the apparatus ID obtained by the optical communication information obtainment unit and state information which is information indicating a state of the apparatus to a server via a network, and obtain user presentation information from the server, the user presentation information being at least one of screen information, sound information, an application, a script, a URL, and link information to another server that correspond to the state information;
• and
• a peripheral apparatus limiting unit configured to select a peripheral apparatus capable of the optical communication based on a current position of the wireless communication terminal, from the terminal position information and the peripheral apparatus information,
• wherein the optical communication information obtainment unit is configured to complement the information received by the optical communication, using information corresponding to the selected peripheral apparatus.
