Abstract

An information processing device includes: a detector information acquiring unit to acquire detector information relating to a position of a detector; a display control unit to cause a display device capable of varying contents to be displayed according to display directions to perform display of different contents or display at a different timing, for each display direction; a display direction acquiring unit to acquire a display direction in which display is recognizable from the position where the detector is installed based on contents or a timing of display by the display device as detected by the detector; and an associating unit to associate the acquired detector information and the acquired display direction with each other.

Claims

1. A system comprising:

a display device configured to vary contents to be displayed according to display directions;

an information processing device configured to control the display device; and

a detector installed at a predetermined location where display by the display device is viewable,

wherein the display device performs display of different contents or display at a different timing, for each display direction, and

a processor of the information processing executes;

accepting an input of detector information relating to a position of the detector;

determining a display direction in which display is recognizable from the position where the detector is installed based on contents or a timing of display by the display device as detected by the detector; and

recording information which indicates a relationship between the detector information acquired with respect to the predetermined location and the display direction specified by using the detector related to the detector information on a table.

2. The system according to claim 1, wherein

the processor acquires detector information relating to the position of the detector installed in a range from which display by the display device is viewable.

3. The system according to claim 1, wherein

the detector information includes information that is acquired using a sensor capable of recognizing an object and that indicates a direction of the detector from the sensor.

4. The system according to claim 1, wherein

the processor performs display control based on display control information that is prepared in advance and that indicates a relationship between the display direction and display contents or a display timing, and

the processor acquires the display direction in which display is recognizable from the position where the detector is installed based on the display contents or the display timing by referring to the display control information.

5. The system according to claim 1, wherein

the information processing device is

a calibration device for calibrating the display direction of a directional input/output device including the display device and a position information acquiring unit that acquires position information of an object within a range from which the display device is viewable.

6. A method in which a system comprising:

a processor;

a memory device;

a display device; and

a detector, the display device configured to vary display contents according to display directions, the processor of an information processing device configured to control the display device, and the detector installed at a predetermined location where display by the display device is viewable, wherein the display device performs display of different contents or display at a different timing, for each display direction, executes the steps of;

accepting, by the processor, an input of detector information that is information relating to a position of the detector;

determining, by the processor, a display direction in which display is recognizable from the position where the detector is installed based on contents or a timing of display by the display device as detected by the detector; and

recording, by the processor, information which indicates a relationship between the detector information acquired with respect to the predetermined location and the display direction specified by using the detector related to the detector information on a table.

7. A non-transitory computer-readable medium recorded with a program for causing a system comprising:

a processor;

a memory device;

a display device; and

a detector, the display device configured to vary display contents according to display directions, the processor of an information processing device configured to control the display device, and the detector installed at a predetermined location where display by the display device is viewable, wherein the display device performs display of different contents or display at a different timing, for each display direction, to execute the steps of;

accepting, by the processor, an input of detector information that is information relating to a position of the detector;

determining, by the processor, a display direction in which display is recognizable from the position where the detector is installed based on contents or a timing of display by the display device as detected by the detector; and

recording, by the processor, information which indicates a relationship between the detector information acquired with respect to the predetermined location and the display direction specified by using the detector related to the detector information on a table.
