Abstract

In position measurement device, a positional data acquirer measures a present position to acquire positional data. A positional data storage sequentially stores the positional data acquired by the positional data acquirer. A determiner determines, on the basis of the positional data sequentially stored by the positional data storage and a predetermined criterion, whether a position of a user at a present time is a position of a location to be recorded. And, a locational information storage stores, if the determiner determines that the position of the user at the present time is the position of the location to be recorded, the positional data of the position as locational information.

Claims

1. A position measurement device comprising:

a positional data acquirer configured to measure a present position to acquire positional data;

a positional data storage configured to sequentially store the positional data acquired by the positional data acquirer;

a determiner configured to determine, on the basis of the positional data sequentially stored by the positional data storage and a predetermined criterion, whether a position of a user at a present time is a position of a location to be recorded; and

a locational information storage configured to store, if the determiner determines that the position of the user at the present time is the position of the location to be recorded, the positional data of the position as locational information.

2. The position measurement device according to claim 1, wherein the determiner determines, on the basis of the positional data sequentially stored by the positional data storage and the predetermined criterion, whether a user stays within a predetermined size of area for over a predetermined time, and determines, if determined that the user stays within the predetermined size of area, that the position of the user at the present time is the position of the location to be recorded.

3. The position measurement device according to claim 2, wherein the determiner determines whether a user stays for over a predetermined time in each of a plurality of areas, each having a different size, wherein the determinations being performed using each of a plurality of predetermined conditions corresponding to each of the plurality of areas.

4. The position measurement device according to claim 1, wherein the determiner determines, if detected a use of a predetermined function of the position measurement device, that the position of the user at the present time is the position of the location to be recorded.

5. The position measurement device according to claim 1, wherein the determiner determines, if detected a use of an external device connected to the position measurement device, that the position of the user at the time of the use is the position of the location to be recorded.

6. The position measurement device according to claim 1, wherein the determiner determines, if detected a use of a predetermined service provided by an external computer system, the position of the user at the time of the use is the position of the location to be recorded.

7. The position measurement device according to claim 1, wherein if detected any one or more uses a use of external device connected to the position measurement device, a use of a predetermined function of the position measurement device, and a use of a predetermined service provided by an external computer system, the determiner determines that the position of the user at the time of the use is the position of the location to be recorded, and

the locational information storage stores, as locational information, history information indicative of the detected use of the predetermined function, the external device or the predetermined service together with positional data at the time of the use.

8. A method for generating locational information comprising:

a measurement step to sequentially store positional data obtained by measuring a present position in a data storage area;

a determination step to determine, on the basis of the positional data sequentially stored in the data storage area, whether a position of a user at a present time is a position of a location to be recorded; and

a locational information step to store, if determined that the position of the user at the present time is the position of the location to be recorded, the positional data of the position as locational information in the data storage area.

9. A computer-readable non-volatile storage medium having stored a program executable by a computer, causing the computer to perform:

a positional data acquisition step to measure a present position to acquire positional data;

a positional data storage step to sequentially store the positional data acquired at the positional data acquisition step;

a determination step to determine, on the basis of the positional data sequentially stored at the positional data storage step, whether a position of a user at a present time is a position of a location to be recorded; and

a locational information step to store, if determined that the position of the user at the present time is the position of the location to be recorded, the positional data of the position as locational information.
