Abstract

An information processing apparatus according to the present disclosure includes: an acquisition unit that acquires a character string whose part of speech is to be estimated; and a generation unit that generates part-of-speech estimation information for estimating a part of speech of the character string based on a byte sequence obtained by converting the character string.

First claim

The invention claimed is:

1. An information processing apparatus comprising:
a control unit configured to
acquire line-of-sight information indicating a gaze point of a user and object information indicating a plurality of objects; and
select one object from the plurality of objects based on a positional relation between the gaze point of the user and the plurality of objects, wherein the control unit is further configured to
acquire the object information indicating boundaries of the plurality of objects, and
select a point on a boundary closest to the gaze point of the user in a boundary of the one object.

2. The information processing apparatus according to claim 1 , wherein
the control unit is further configured to select the one object, which is an object closest to the gaze point of the user.

3. The information processing apparatus according to claim 1 , wherein
the control unit is further configured to select a plurality of points on the boundary of the one object in accordance with movement of the gaze point of the user.

4. The information processing apparatus according to claim 3 , wherein
the control unit is further configured to generate an area having a boundary indicated by a line connecting the plurality of points in an order that the plurality of points was selected.

5. The information processing apparatus according to claim 4 , wherein
the control unit is further configured to change the area by changing a position of one of the plurality of points.

6. The information processing apparatus according to claim 4 , wherein
the control unit is further configured to change the area by adding a new point to the plurality of points.

7. The information processing apparatus according to claim 1 , wherein
the control unit is further configured to acquire the object information indicating the boundaries of the plurality of objects detected from an image.

8. The information processing apparatus according to claim 7 , wherein
the control unit is further configured to acquire the object information indicating the boundaries of the plurality of objects detected from each of a plurality of images.

9. An information processing method to be executed by an information processing apparatus, the method comprising:
acquiring line-of-sight information indicating a gaze point of a user, and object information indicating a plurality of objects and boundaries of the plurality of objects;
selecting one object from the plurality of objects based on a positional relation between the gaze point of the user and the plurality of objects; and
selecting a point on a boundary closest to the gaze point of the user in a boundary of the one object.

10. An information processing apparatus comprising:
control unit configured to
acquire line-of-sight information indicating a gaze point of a user and area information indicating a plurality of areas based on arrangement of objects; and
select one area from the plurality of areas based on a positional relation between the gaze point of the user and the plurality of areas, wherein

the control unit is further configured to
acquire the area information indicating the plurality of areas based on boundaries of the objects, and
select the one area corresponding to one of the objects that has a boundary in which the gaze point of the user is located.

11. The information processing apparatus according to claim 10 , wherein
the control unit is further configured to select the one area, which is an area where the gaze point of the user is located, from the plurality of areas.

12. The information processing apparatus according to claim 10 , wherein
the control unit is further configured to select the one area as an area to be processed in relation to editing.

13. The information processing apparatus according to claim 12 , wherein
the control unit is further configured to generate a mesh that divides the one area into a plurality of partial areas.

14. The information processing apparatus according to claim 13 , wherein
the control unit is further configured to generate the mesh that divides the one area into the plurality of partial areas each having a rectangular shape.

15. The information processing apparatus according to claim 13 , wherein
the control unit is further configured to acquire designation information indicating designation of the user for the plurality of partial areas, and select a partial area designated by the user from the plurality of partial areas.

16. The information processing apparatus according to claim 15 , wherein
the control unit is further configured to acquire the designation information indicating designation given by a line of sight of the user for the plurality of partial areas, and select a partial area designated by the user based on the line of sight of the user.

17. The information processing apparatus according to claim 15 , wherein
the control unit is further configured to acquire the designation information indicating designation of a range in the one area given by a line of sight of the user, and select a partial area located in the range from the plurality of partial areas.
