Abstract

There is provided a mechanism to help a user to notice by guiding the user. An information processor including a guidance controller that causes a projection device to project, in a space in which a user is located, guidance information for guiding the user to a guidance location, on the basis of environment information regarding the space and user information indicating a position and a line of sight of the user.

First claim

The invention claimed is:

1. An information processor comprising
a guidance controller configured to cause a projection device to project, in a space in which a user is located, guidance information for guiding the user to a guidance location, based on environment information regarding the space and user information indicating a position and a line of sight of the user,
wherein the guidance controller causes the projection device to project the guidance information in a plurality of projection locations sequentially, and
wherein the guidance controller is implemented via at least one processor.

2. The information processor according to claim 1 , wherein the guidance controller switches a method of guiding the user based on the environment information or the user information.

3. The information processor according to claim 2 , wherein the guidance controller determines a projection route of the guidance information between the plurality of projection locations based on the environment information or the user information.

4. The information processor according to claim 3 , wherein the guidance controller determines the projection route so as to avoid a region that does not meet criteria for visibility of the guidance information among regions included in the space.

5. The information processor according to claim 3 , wherein the guidance controller determines the projection route based on information regarding an illuminance or a color of the region included in the space.

6. The information processor according to claim 3 , wherein the guidance controller changes between the plurality of projection locations of the guidance information in stages by tracking the user's line of sight.

7. The information processor according to claim 3 , wherein the guidance controller changes between the plurality of projection locations of the guidance information in stages by tracking the position of the user.

8. The information processor according to claim 3 , wherein:
the projection device includes a movable portion capable of changing a projection direction; and
the guidance controller changes a projection location of the guidance information by changing the projection direction of the projection device.

9. The information processor according to claim 2 , wherein the guidance controller determines what device the guidance controller shall cause to output the guidance information, based on the environment information or the user information.

10. The information processor according to claim 9 , wherein the guidance controller causes an audio output device to output a sound such that the sound comes to the user from a direction of a projection location of the guidance information.

11. The information processor according to claim 2 , wherein the guidance information includes information indicating an action to be performed by the user for guidance.

12. The information processor according to claim 11 , wherein the guidance controller determines an action to be performed by the user, based on the environment information or the user information.

13. The information processor according to claim 1 , wherein the guidance information includes information indicating a degree of urgency.

14. The information processor according to claim 1 , wherein the guidance information includes information indicating a guidance direction.

15. The information processor according to claim 1 , wherein the guidance information includes information indicating a state of the guidance location in a representation in which a part of a shield is transparent.

16. The information processor according to claim 1 further comprising:
a setting unit configured to set the guidance location,
wherein the setting unit sets in advance the guidance location corresponding to a predetermined trigger, and
wherein the setting unit is implemented via at least one processor.

17. The information processor according to claim 1 further comprising:
a setting unit configured to set the guidance location,
wherein the setting unit sets, as the guidance location, a location corresponding to notification information generated for the user, and
wherein the setting unit is implemented via at least one processor.

18. The information processor according to claim 1 , wherein the environment information includes information indicating a shape of an object forming the space.

19. An information processing method comprising:
causing a projection device to project, in a space in which a user is located, guidance information for guiding the user to a guidance location, based on environment information regarding the space and user information indicating a position and a line of sight of the user,
wherein the guidance information is projected in a plurality of projection locations sequentially.

20. A non-transitory computer-readable storage medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
causing a projection device to project, in a space in which a user is located, guidance information for guiding the user to a guidance location, based on environment information regarding the space and user information indicating a position and a line of sight of the user,
wherein the guidance information is projected in a plurality of projection locations sequentially.
