Information processing device, display control method, a program, and an information storage medium

1. An information processing device comprising:

a positioning unit configured to sequentially calculate a position of the information processing device;

a position storing unit configured to store a plurality of positions including at least one position of at least one other information processing device;

a storing unit configured to store the position calculated by the positioning unit into the position storing unit; and

a display unit configured to display a plurality of information items indicating all or a part of the positions stored in the position storing unit in a unidirectional order that the positions are calculated, and control a distance between adjacent information items based on a distance between the positions indicated by the adjacent information items, wherein

at least one of the information items indicates at least one position of the information processing device and at least another of the information items indicates at least one position of the at least one other information processing device.

2. The information processing device according to claim 1 , wherein when the distance between the positions indicated by the adjacent information items is less than a predetermined minimum distance, the display unit sets the distance between the adjacent information items to the predetermined minimum distance.

3. The information processing device according to claim 1 , wherein when the distance between the positions indicated by the adjacent information items is equal to or greater than a predetermined maximum distance, the display unit sets the distance between the adjacent information items to the predetermined maximum distance.

4. The information processing device according to claim 1 , wherein the display unit controls the distance between the adjacent information items depending on whether or not positioning times of the positions indicated by the adjacent information items sandwich a predetermined time.

5. The information processing device according to claim 1 , wherein the display unit displays a display position of each of the information items such that the display position is staggered with respect to a direction in which the information items are arranged, according to a positioning time of each of the information items.

6. The information processing device according to claim 1 ,

wherein the storing unit stores the position calculated by the positioning unit together with a calculating date/time of the position into the position storing unit, and

wherein the display unit displays the calculating date/time of the position together with information indicating the position.

7. The information processing device according to claim 1 , wherein the information item is a letter string.

8. The information processing device according to claim 7 , wherein the information item is a letter string that indicates a name of all or a part of the plurality of positions stored in the position storing unit.

9. A display control method comprising:

sequentially calculating a position of an information processing device;

storing into the storing unit a plurality of positions including the position calculated by the positioning unit and including at least one position of at least one other information processing device; and

displaying a plurality of information items indicating all or a part of the positions stored in the position storing unit in a unidirectional order that the positions are calculated, and controlling a distance between adjacent information items based on a distance between the positions indicated by the adjacent information items, wherein

at least one of the information items indicates at least one position of the information processing device and at least another of the information items indicates at least one position of the at least one other information processing device.

10. A computer operating under the control of a computer program to execute the steps of:

sequentially calculating a position of an information processing device;

storing into the position storing unit a plurality of positions including the position calculated by the positioning unit and including at least one position of at least one other information processing device; and

displaying a plurality of information items indicating all or a part of the positions stored in the position storing unit in a unidirectional order that the positions are calculated, and controlling a distance between adjacent information items based on a distance between the positions indicated by the adjacent information items, wherein

at least one of the information items indicates at least one position of the information processing device and at least another of the information items indicates at least one position of the at least one other information processing device.

11. A non-transitory, computer-readable storage medium containing a program, which when executed by a computer cause the computer to carry out the steps of:

sequentially calculating a position of an information processing device;

storing into the position storing unit a plurality of positions including the position calculated by the positioning unit and including at least one position of at least one other information processing device; and

displaying a plurality of information items indicating all or a part of the positions stored in the position storing unit in a unidirectional order that the positions are calculated, and controlling a distance between adjacent information items based on a distance between the positions indicated by the adjacent information items, wherein

at least one of the information items indicates at least one position of the information processing device and at least another of the information items indicates at least one position of the at least one other information processing device.
