Abstract

In a location identifying method, the sight of users of mobile communication terminals is estimated by calculating directions of the users based on position information of the mobile communication terminals, and the location where the lines of sight of the users are concentrated is identified based on the estimated sight. By identifying a location where the lines of sight of the users of the mobile communication terminals are concentrated, it is possible to identify an installation location where high advertising effectiveness can be achieved. Moreover, since only acquisition of the position information of the mobile communication terminals is needed, it is possible to efficiently identify an installation location of an advertisement, etc. Therefore, it is possible to efficiently identify an installation location of an advertisement or a billboard where high advertising effectiveness can be achieved.

Claims

1. A location identifying method for obtaining position information of mobile communication terminals and identifying a location where lines of sight of users having the mobile communication terminals are concentrated, the location identifying method comprising:

a direction calculating step of, by a direction calculating unit, calculating directions of the users of the mobile communication terminals based on the position information of the mobile communication terminals;

a sight estimating step of, by a sight estimating unit, estimating the sight of the users based on the directions of the users of the mobile communication terminals calculated in the direction calculating step; and

a location identifying step of, by a location identifying unit, identifying a location where the lines of sight of the users are concentrated based on multiplicity of the sight of the users estimated in the sight estimating step with a predetermined boundary.

2. The location identifying method according to claim 1, wherein the location identifying step weights a location where the lines of sight are concentrated based on attribute information of the users.

3. The location identifying method according to claim 1, wherein the sight estimating step corrects the sight based on the attribute information of the users.

4. The location identifying method according to claim 1, wherein the direction calculating step corrects the directions of the users of the mobile communication terminals in accordance with traveling conditions of the users.

5. The location identifying method according to claim 1, wherein the sight estimating step corrects the sight based on traveling velocity of the mobile communication terminals.

6. The location identifying method according to claim 1, wherein the location identifying step identifies a location where the lines of sight of the users are concentrated by counting how many times the sight of the users crosses with side faces of a building divided in a given length.

7. The location identifying method according to claim 1, wherein the location identifying step identifies a location where the lines of sight of the users are concentrated by counting how many times the sight of the users crosses with side faces of the building divided based on vertices at which the sight of the users and the building cross.

8. A location identifying device that obtains position information of mobile communication terminals and identifies a location where lines of sight of users having mobile communication terminals are concentrated, the location identifying device comprising:

a direction calculating unit calculating directions of the users of the mobile communication terminals based on the position information of the mobile communication terminals;

a sight estimating unit estimating the sight of the users based on directions of the users of the mobile communication terminals calculated by the direction calculating means; and

a location identifying unit identifying a location where the lines of sight of the users are concentrated based on multiplicity of the sight of the users estimated by the sight estimating means with a predetermined boundary.
