Abstract

A portable terminal sends to a second server sound contents request information comprising a tag ID corresponding to light received from an illumination device, the light-receiving position on the light-receiving surface, and the area ratio of the light-receiving range to the light-receiving surface in order to acquire sound contents. The second server 700 combines individual sound contents corresponding to the tag ID in the sound contents request information, first basic sound contents corresponding to the light-receiving position, and second basic sound contents corresponding to the area ratio. Then, the second server creates sound contents for giving information about the object present at the location where the illumination device emitting the light corresponding to the tag ID is installed and the direction and distance of the object when seen from the portable terminal and sends the sound contents to the portable terminal.

First claim

What is claimed is:

1. A terminal device in an information provision system including a transmission device, the terminal device, and a server system providing information-to-provide to the terminal device, the terminal device comprising:
a light receiver comprising a light-receiving surface comprising multiple light-receiving elements two-dimensionally arrayed;
a controller which functions as:
an identification information acquirer demodulating light transmitted from the transmission device and received by the light receiver to acquire identification information; and
a light-receiving condition acquirer acquiring at least one of (i) position information indicating a position of the light-receiving surface where the light is received and (ii) range information indicating a range of the light-receiving surface over which the light is received, when the light receiver receives the light from the transmission device; and

a transmitter transmitting the identification information acquired by the identification information acquirer and the at least one of the position information and the range information acquired by the light-receiving condition acquirer to the server system.

2. The terminal device according to claim 1 , wherein the controller further functions as:
a content acquirer acquiring content information corresponding to the identification information acquired by the identification information acquirer; and
a determiner determining whether the content information contains specific information, and
wherein the transmitter transmits the content information acquired by the content acquirer and the at least one of the position information and the range information acquired by the acquirer to the server system when the determiner determines that the content information contains the specific information.

3. The terminal device according to claim 2 , wherein:
the content information is information for defining a location of the server system on a network,
the specific information is information for nullifying the information for defining the location by adding a character string to the information for defining the location, and
the transmitter deletes the character string added to the information for defining the location to make the information for defining the location usable by the terminal device.

4. The terminal device according to claim 1 , further comprising:
a receiver receiving the information-to-provide from the server;
wherein the controller further controls an output of the terminal device based on the information-to-provide received by the receiver.

5. The terminal device according to claim 4 , wherein the information-to-provide comprises sound information, and the controller controls the terminal device to output sound based on the sound information received by the receiver.

6. An information provision method of a terminal device in an information provision system including a transmission device, the terminal device, and a server system providing information-to-provide to the terminal device, the method comprising:
a light reception step of receiving light from the transmission device with a light receiver comprising a light-receiving surface comprising multiple light-receiving elements two-dimensionally arrayed;
an identification information acquisition step of demodulating the light received in the light reception step to acquire identification information;
a light-receiving condition acquisition step of acquiring at least one of (i) position information indicating a position of the light-receiving surface where the light is received and (ii) range information indicating a range of the light-receiving surface over which the light is received, when the light is received from the transmission device by the light receiver in the light reception step;
a transmission step of transmitting the identification information acquired in the identification information acquisition step and the at least one of the position information and the range information acquired in the light-receiving condition acquisition step to the server system;
a reception step of receiving the information-to-provide transmitted by the server system in response to the transmitting of the identification information and the at least one of the position information and the range information in the transmission step; and
an output step in which the terminal device outputs sound based on the information-to-provide received in the reception step.

7. A non-transitory computer-readable recording medium having a program recorded thereon for controlling a computer of a terminal device in an information provision system, the information provision system including a transmission device, the terminal device, and a server system providing information-to-provide to the terminal device, and the program being executable to control the computer to function as:
an identification information acquirer demodulating light transmitted from the transmission device and received by a light receiver comprising a light-receiving surface comprising multiple light-receiving elements two-dimensionally arrayed to acquire identification information;
a light-receiving condition acquirer acquiring at least one of (i) position information indicating a position of the light-receiving surface where the light is received and (ii) range information indicating a range of the light-receiving surface over which the light is received, when the light receiver receives the light from the transmission device;
a transmitter transmitting the identification information acquired by the identification information acquirer and the at least one of the position information and the range information acquired by the light-receiving condition acquirer to the server system;
a receiver receiving the information-to-provide transmitted by the server system in response to the transmitting of the identification information and the at least one of the position information and the range information by the transmitter; and
an output controller controlling the terminal device to output sound based on the information-to-provide received by the receiver.
