Abstract

Information is provided by a voice taking users into account. An information providing system provides information using a voice. A position direction acquisition unit acquires position information indicating a position of a user, and sight direction information indicating a sight direction that is a direction that a face of the user faces. A storage unit stores, in advance, object position information indicating respective positions of a plurality of objects that may be viewed by the user, and explanation information for explaining each of the objects. An estimation unit estimates the object being viewed by the user based on the position information and the sight direction information of the user, and the object position information. An information output unit outputs the explanation information of the estimated object using the voice.

First claim

1 . An information providing system that provides information using a voice comprising:
a position direction acquisition unit that acquires position information indicating a position of a user, and sight direction information indicating a sight direction that is a direction that a face of the user faces; a storage unit that stores, in advance, object position information indicating respective positions of a plurality of objects that may be viewed by the user, and explanation information for explaining each of the plurality of objects; an estimation unit that estimates the object being viewed by the user based on the position information and the sight direction information of the user, and the object position information; and an information output unit that outputs the explanation information of the estimated object using the voice.

2 . The information providing system according to claim 1 , wherein
the voice is output from a voice output device worn on a head of the user, the storage unit stores, in advance, information indicating a virtual position of a sound source associated with each of the objects, and the information output unit outputs a voice obtained by performing stereophonic processing on the voice indicating the explanation information according to the virtual position of the sound source seen from a current position of the user.

3 . The information providing system according to claim 1 , wherein
the storage unit stores setting information of a visual field in which a range that can be seen by eye of the user is set in advance, and the estimation unit estimates the object being viewed by the user within the range of the visual field set in advance.

4 . The information providing system according to claim 1 , wherein, when the estimation unit detects that a predetermined time has passed after the object being viewed by the user changes, the information output unit stops outputting the voice for the explanation information of the object that the user has lastly viewed.

5 . The information providing system according to claim 1 , further comprising:
mobile terminals carried by a plurality of the users; and at least one server, wherein each of the mobile terminals includes the position direction acquisition unit, the storage unit, the estimation unit, and the information output unit, the estimation unit supplies, to the server, visibility data including information for identifying the object estimated to be viewed by the user, information indicating a date and a time of the estimation, and information for identifying the user, and the server includes:
a data accumulation unit that accumulates the visibility data supplied from the estimation unit, and
a statistical data generation unit that generates, per object, statistical data indicating a distribution of attributes of the users from attribute data indicating the attributes of the users, and the visibility data, and outputs the statistical data.

6 . A method of providing information using a voice by a computer carried by a user, the method comprising:
acquiring, by the computer, position information indicating a position of a user, and sight direction information indicating a sight direction that is a direction that a face of the user faces; estimating, by the computer, the object being viewed by the user based on the position information and the sight direction information of the user, and object position information set in advance for each of a plurality of objects that may be viewed by the user; and outputting, by the computer, explanation information of the estimated object using the voice.

7 . A program executed by a computer carried by a user, the program causing the computer to implement:
a function of acquiring position information indicating a position of a user, and sight direction information indicating a sight direction that is a direction that a face of the user faces; a function of estimating the object being viewed by the user based on the position information and the sight direction information of the user, and object position information set in advance for each of a plurality of objects that may be viewed by the user; and a function of outputting explanation information of the estimated object using the voice.
