Abstract

An information processing apparatus that detects a first location of the information processing apparatus; receives information representing a target location from a target information processing apparatus; detects a target direction from the first location toward the target location; detects an orientation of a casing of the information processing apparatus; calculates an angular difference between the target direction and the orientation of the casing; determines a perceptual strength of each of a plurality of active elements disposed in different locations on or within the casing based on the angular difference; and controls each of the plurality of active elements based on the perceptual strengths.

Claims

1. An information processing apparatus comprising:

a casing;

a location detecting unit that detects a first location of the information processing apparatus;

a communication interface that receives information representing a target location from a target information processing apparatus;

a processor that detects a target direction from the first location toward the target location;

a detector that detects an orientation of the casing;

a perceptual active unit including a plurality of active elements disposed in different locations on or within the casing, wherein

the processor calculates an angular difference between the target direction and the orientation of the casing, determines a perceptual strength of each of the plurality of active elements based on the angular difference, and controls each of the plurality of active elements based on the perceptual strengths.

2. The information processing apparatus of claim 1, wherein

the location detecting unit continuously updates the first location of the information processing apparatus by detecting the position of the information processing apparatus at first predetermined time intervals.

3. The information processing apparatus of claim 2, wherein

the processor continuously updates the target direction based on the continuously updated first location of the information processing apparatus by the location detecting unit.

4. The information processing apparatus of claim 3, wherein

the detector continuously updates the orientation of the casing by detecting the orientation of the casing at second predetermined time intervals.

5. The information processing apparatus of claim 4, wherein

the processor continuously updates the angular difference between the target direction and the orientation of the casing based on the continuously updated orientation of the casing detected by the detector.

6. The information processing apparatus of claim 5, wherein

the processor continuously determines the perceptual strength of each of the plurality of active elements based on the updated angular difference, and controls each of the plurality of active elements based on the perceptual strengths.

7. The information processing apparatus of claim 1, wherein

the processor controls the communication interface to transmit the first location of the information processing apparatus to the target information processing apparatus.

8. The information processing apparatus of claim 2, wherein

the processor controls the communication interface to transmit the continuously updated the first location of the information processing apparatus to the target information processing apparatus.

9. The information processing apparatus of claim 1, wherein

the processor calculates a distance from the first information processing apparatus to the target information processing apparatus based on the first location information and the target location.

10. The information processing apparatus of claim 9, further comprising:

a display, wherein

the processor controls the display to display a numeric value representing the calculated distance.

11. The information processing apparatus of claim 1, further comprising:

a display, wherein

the processor controls the display to display a graphic indicator representing the target direction.

12. The information processing apparatus of claim 11, wherein

the graphic indicator is an arrow pointing in the target direction.

13. The information processing apparatus of claim 12, wherein

the processor calculates a distance from the first information processing apparatus to the target information processing apparatus based on the first location information and the target location, and controls a length of the arrow displayed on the display based on the calculated distance.

14. The information processing apparatus of claim 1, wherein

the plurality of active elements are at least one of vibration elements, heating elements, contraction elements, and electrical stimulation elements.

15. The information processing apparatus of claim 1, wherein

the perceptual active element includes at least three active elements disposed in different locations on or within the casing.

16. The information processing apparatus of claim 9, wherein

the plurality of active elements are vibration elements, and the processor controls the plurality of active elements to be active only when the calculated distance is greater than a predetermined threshold.

17. The information processing apparatus of claim 9, wherein

the plurality of active elements are vibration elements, and the processor controls the plurality of active elements by changing a vibration frequency of each of the plurality of active elements based on the calculated distance.

18. An information processing method performed by an information processing apparatus, the method comprising:

detecting a first location of the information processing apparatus;

receiving information representing a target location from a target information processing apparatus;

detecting a target direction from the first location toward the target location;

detecting an orientation of a casing of the information processing apparatus;

calculating an angular difference between the target direction and the orientation of the casing;

determining a perceptual strength of each of a plurality of active elements disposed in different locations on or within the casing based on the angular difference; and

controlling each of the plurality of active elements based on the perceptual strengths.

19. A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing apparatus, cause the information processing apparatus to perform a method comprising:

detecting a first location of the information processing apparatus;

receiving information representing a target location from a target information processing apparatus;

detecting a target direction from the first location toward the target location;

detecting an orientation of a casing of the information processing apparatus;

calculating an angular difference between the target direction and the orientation of the casing;

determining a perceptual strength of each of a plurality of active elements disposed in different locations on or within the casing based on the angular difference; and

controlling each of the plurality of active elements based on the perceptual strengths.
