change an appearance of the first display object based on the output of the attracting region and the determination of the non-gazing state.

2. The information processing device according to claim 1 , wherein the display control unit is further configured to gradually change the appearance of the first display object every time the gazing state is changed to the non-gazing state.

3. The information processing device according to claim 1 , wherein the display control unit is further configured to gradually increase, based on an elapse of a specific time, an amount of the change in the appearance of the first display object.

4. The information processing device according to claim 1 , wherein the output of the attracting region includes one of display of an attracting object at the position spaced apart from the first display object or increase in visual attraction of a region spaced apart from the first display object.

5. The information processing device according to claim 1 , further comprising a sound control unit configured to output sound information having a sound image localized at the position spaced apart from the first display object, wherein

the display control unit is further configured to change the appearance of the first display object based on the determination of the non-gazing state for the first display object, and

the change in the appearance of the first display object is subsequent to the output of the sound information.

6. The information processing device according to claim 1 , wherein the determining unit is further configured to determine the one of the gazing state or the non-gazing state of the first user for the first display object, based on one of the line of sight of the first user, an orientation of a face of the first user, or an orientation of a head of the first user.

7. The information processing device according to claim 1 , wherein the change in the appearance of the first display object is difficult to be recognized by the first user.

8. The information processing device according to claim 7 , wherein

the display control unit is further configured to change an appearance of a second display object of a plurality of display objects associated with the second real space,

the first display object has a visual attraction lower than that of the second display object,

the change in the appearance of the second display object is subsequent to the change in the appearance of the first display object, and

the plurality of display objects includes the first display object.

9. The information processing device according to claim 7 , wherein

the display control unit is further configured to change an appearance of a second display object of a plurality of display objects associated with the second real space,

a spatial distance of the first display object from a gaze point of the first user is longer than a spatial distance of the second display object from the gaze point,

the change in the appearance of the second display object is subsequent to the change in the appearance of the first display object, and

the plurality of display objects includes the first display object.

10. The information processing device according to claim 7 , wherein

the first display object corresponds to a second user present in the second real space, and

the display control unit is further configured to change an appearance of a part of the second user different from a face of the second user.

11. The information processing device according to claim 7 , wherein

the first display object is different from a second user present in the second real space, and

the display control unit is further configured to change the appearance of the first display object that is at an end of an angle of view displayed by the display device.

12. The information processing device according to claim 1 , wherein the display control unit is further configured to control an amount of the change based on whether the first display object looks familiar to the first user.

13. The information processing device according to claim 1 , wherein the first display object is a real object imaged in the second real space.

14. The information processing device according to claim 1 , wherein the display control unit is further configured to adjust an amount of the change in the appearance of the first display object based on sensitivity of the first user to change.

15. The information processing device according to claim 13 , wherein in a case where an appearance of the real object is in a state deviated from a given trend, the display control unit is further configured to change the appearance of the first display object such that the changed appearance fulfills the given trend.

16. An information processing method performed by a processor, the information processing method comprising:

determining one of a gazing state or a non-gazing state of a user present in a first real space, for a display object displayed by a display device of the user,

wherein the display object is associated with a second real space different from the first real space;

controlling output of an attracting region at a position spaced apart from the display object, to attract a line of sight of the user to the attracting region; and

changing an appearance of the display object based on the output of the attracting region and the determination of the non-gazing state.

17. A non-transitory computer-readable medium having stored thereon computer-executable instructions, which when executed by a processor, cause the processor to execute operations, the operations comprising:

determining one of a gazing state or a non-gazing state of a user present in a first real space, for a display object displayed by a display device of the user,

wherein the display object is associated with a second real space different from the first real space;

controlling output of an attracting region at a position spaced apart from the display object, to attract a line of sight of the user to the attracting region; and

changing an appearance of the display object based on the output of the attracting region and the determination of the non-gazing state.

18. An information processing device, comprising:

a determining unit configured to determine one of a gazing state or a non-gazing state of a user present in a first real space, for a display object displayed by a display device of the user,

wherein the display object is associated with a second real space different from the first real space;

a sound control unit configured to output sound information having a sound image localized at a position spaced apart from the display object; and

a display control unit configured to change an appearance of the display object based the determination of the non-gazing state for the display object,

wherein the change in the appearance of the display object is subsequent to the output of the sound information.
