Information processing device, control method, and non-transitory computer readable medium for determining user interest based on line-of-sight information
An information processing device according to the present disclosure includes one or more processors and/or circuitry configured to execute first acquisition processing of acquiring line-of-sight information of a user, execute detection processing of detecting an object viewed by the user based on the line-of-sight information, execute second acquisition processing of acquiring, from a storage, reference information for determining a degree of interest of the user with respect to the object, the reference information being predetermined information corresponding to the object, and execute determination processing of determining the degree of interest based on the line-of-sight information and the reference information.
1 . An information processing device comprising
one or more processors and/or circuitry configured to:
execute first acquisition processing of acquiring line-of-sight information of a user;
execute detection processing of detecting an object viewed by the user based on the line-of-sight information;
execute second acquisition processing of acquiring, from a storage, reference information for determining a degree of interest of the user with respect to the object, the reference information being predetermined information corresponding to the object; and
execute determination processing of determining the degree of interest based on the line-of-sight information and the reference information, wherein
the reference information indicates a reference for determining the degree of interest for each of a plurality of areas of the object, and
the degree of interest of whole of the object is determined based on line-of-sight information for each of the plurality of areas and the reference information.
2 . The information processing device according to claim 1 , wherein
in the first acquisition processing, line-of-sight information for a right eye of the user and line-of-sight information for a left eye of the user are acquired, and
in the detection processing, a three-dimensional position of the object is detected based on the line-of-sight information for the right eye of the user and line-of-sight information for the left eye of the user.
3 . The information processing device according to claim 1 , wherein
the one or more processors and/or circuitry further executes a recording processing of recording the degree of interest in a server.
4 . A head mounted display device comprising:
the information processing device according to claim 1 ; and
a display.
5 . The information processing device according to claim 1 , wherein
the reference information includes information on an order in which the plurality of areas are viewed.
6 . The information processing device according to claim 1 , wherein
the reference information includes information on a length of time for viewing each of the plurality of areas.
7 . The information processing device according to claim 1 , wherein
even in a case where the plurality of areas are viewed for a same length of time, an effect on determination of the degree of interest of the whole of the object is changed depending on types of the plurality of areas.
8 . The information processing device according to claim 7 , wherein
the object is an advertisement medium, and
even in a case where the plurality of areas are viewed for a same length of time, the effect on the degree of interest is greater in a case where the user views, among the plurality of areas, an area conforming to an advertisement purpose of the advertisement medium than in a case where the user does not view the area conforming to the advertisement purpose of the advertisement medium.
9 . The information processing device according to claim 1 , wherein
even in a case where any one of the plurality of areas is viewed for a same length of time, an effect on determination of the degree of interest is greater in a case where the user views an image area of an advertisement target than in a case where the user views a text area.
10 . A control method of an information processing device, comprising:
acquiring line-of-sight information of a user;
detecting an object viewed by the user based on the line-of-sight information;
acquiring, from a storage, reference information for determining a degree of interest of the user with respect to the object, the reference information being predetermined information corresponding to the object; and
determining the degree of interest based on the line-of-sight information and the reference information, wherein
the reference information indicates a reference for determining the degree of interest for each of a plurality of areas of the object, and
the degree of interest of whole of the object is determined based on line-of-sight information for each of the plurality of areas and the reference information.
11 . A non-transitory computer readable medium that stores a program, wherein the program causes a computer to execute a control method of an information processing device, the control method comprising:
acquiring line-of-sight information of a user;
detecting an object viewed by the user based on the line-of-sight information;
acquiring, from a storage, reference information for determining a degree of interest of the user with respect to the object, the reference information being predetermined information corresponding to the object; and
determining the degree of interest based on the line-of-sight information and the reference information, wherein
the reference information indicates a reference for determining the degree of interest for each of a plurality of areas of the object, and
the degree of interest of whole of the object is determined based on line-of-sight information for each of the plurality of areas and the reference information.
