Information processing apparatus, information processing method, program, and mobile object
This technology relates to an information processing apparatus for accurately notifying a mobile object of a position of a moving body nearby, and to an information processing method, a program, and a mobile object for use with the information processing apparatus. The information processing apparatus includes a moving body detection section that detects the moving body near the mobile object on the basis of information input from sensors, and a sound output control section that shifts the position of a sound image of a notification sound giving notification of the position of the moving body in keeping with a detected position thereof in motion. This technology can be applied to apparatuses, systems, or vehicles that provide driver assistance for preventing collision or contact with the moving body, for example.

wherein the sound output control section performs control to determine whether the moving body has a set priority of highest priority or of a priority lower than the highest priority, and if the set priority is the highest priority, output the notification sound, and if the set priority is the priority lower than the highest priority, not output the notification sound.
2. The information processing apparatus according to claim 1 , further comprising:
a motion prediction section configured to predict motion of the moving body, wherein the sound output control section shifts the position of the sound image of the notification sound on a basis of a predicted position of the moving body.
3. The information processing apparatus according to claim 2 , wherein,
from a time the position of the sound image of the notification sound is set on a basis of a first detected position of the moving body until the position of the sound image of the notification sound is set on a basis of a second detected position of the moving body subsequent to the first detected position, the sound output control section sets the position of the sound image of the notification sound in accordance with the predicted position of the moving body.
4. The information processing apparatus according to claim 2 , wherein
the motion prediction section further predicts the motion of the mobile object, and
the sound output control section shifts the position of the sound image of the notification sound on a basis of the predicted position of the moving body relative to the predicted position of the mobile object.
5. The information processing apparatus according to claim 1 , wherein
the sound output control section controls volume of the notification sound on a basis of a distance between the mobile object and the moving body.
6. The information processing apparatus according to claim 1 , wherein
the sound output control section changes a type of the notification sound depending on a type of the moving body.
7. The information processing apparatus according to claim 6 , wherein
in a case where there are a plurality of moving bodies of the same type near the mobile object, the sound output control section changes the type of the notification sound for each of the moving bodies.
8. The information processing apparatus according to claim 1 , further comprising:
a priority setting section configured to set the priority for the moving body, wherein the sound output control section controls the output of the notification sound regarding each of a plurality of moving bodies on a basis of the priority thereof.
9. The information processing apparatus according to claim 8 , wherein
the sound output control section performs control to preferentially output the notification sound regarding the moving body having a high priority.
10. The information processing apparatus according to claim 8 , wherein
the sound output control section controls the volume of the notification sound on a basis of the priority.
11. The information processing apparatus according to claim 8 , wherein
the priority setting section sets the priority for each moving body on a basis of a risk level at which the moving body can contact or collide with the mobile object.
12. The information processing apparatus according to claim 1 , wherein
the sound output control section performs control to output the notification sound regarding the moving body that comes into a predetermined range of vicinity of the mobile object.
13. The information processing apparatus according to claim 1 , wherein
the sound output control section controls an up-down-direction position of the sound image of the notification sound on a basis of an up-down-direction position of the moving body in reference to a plane on which the moving body exists.
14. The information processing apparatus according to claim 13 , wherein
the sound output control section controls the up-down-direction position of the sound image of the notification sound by controlling output of sounds from a plurality of speakers arranged at different heights in the mobile object.
15. The information processing apparatus according to claim 1 , wherein
the sound output control section controls output of sounds from a plurality of speakers arranged in the mobile object in a manner surrounding a driver of the mobile object.
16. The information processing apparatus according to claim 1 , wherein
the sound output control section shifts the position of the sound image of the notification sound in keeping with the detected position of the moving body in motion relative to the mobile object.
17. An information processing method comprising:
detecting a moving body near a mobile object on a basis of information input from sensors;
shifting a position of a sound image of a notification sound giving notification of a position of the moving body in keeping with a detected position of the moving body in motion; and
performing control to determine whether the moving body has a set priority of highest priority or of a priority lower than the highest priority, and if the set priority is the highest priority, output the notification sound, and if the set priority is the priority lower than the highest priority, not output the notification sound.
18. At least one non-transitory computer-readable storage medium storing processor-executable instructions that, when executed by at least one processor, cause the at least one processor to perform a method comprising:
detecting a moving body near a mobile object on a basis of information input from sensors;
shifting a position of a sound image of a notification sound giving notification of a position of the moving body in keeping with a detected position of the moving body in motion; and
performing control to determine whether the moving body has a set priority of highest priority or of a priority lower than the highest priority, and if the set priority is the highest priority, output the notification sound, and if the set priority is the priority lower than the highest priority, not output the notification sound.
19. A mobile object comprising:
sensors configured to be arranged in the mobile object to detect peripheral status thereof;
a moving body detection section configured to detect a moving body nearby on a basis of information input from the sensors; and
a sound output control section configured to shift a position of a sound image of a notification sound giving notification of a position of the moving body in keeping with a detected position of the moving body in motion,
wherein the sound output control section performs control to determine whether the moving body has a set priority of highest priority or of a priority lower than the highest priority, and if the set priority is the highest priority, output the notification sound, and if the set priority is the priority lower than the highest priority, not output the notification sound.
