Abstract

An information processing device includes a communication unit that performs wireless communication using a specific band with another information processing device; and an estimation unit that estimates a position of the another information processing device on the basis of information regarding a beam used at the time of the wireless communication.

Claims

1. An information processing device comprising:

a communication unit that performs wireless communication using a specific band with another information processing device; and

an estimation unit that estimates a position of the another information processing device on the basis of information regarding a beam used at the time of the wireless communication.

2. The information processing device according to claim 1,

wherein the information regarding the beam includes angle information for specifying at least one of a transmission direction of a transmitted beam used at the time of the wireless communication and a reception direction of a received beam used at the time of the wireless communication, and

wherein the estimation unit calculates a direction of the another information processing device in a case based on a position of the information processing device on the basis of the angle information to estimate the position of the another information processing device.

3. The information processing device according to claim 2, wherein the estimation unit calculates reliability regarding the calculated direction of the another information processing device on the basis of the angle information.

4. The information processing device according to claim 1,

wherein the information regarding the beam includes received signal intensity at the time of the wireless communication, and

wherein the estimation unit calculates a distance between the information processing device and the another information processing device on the basis of the received signal intensity to estimate the position of the another information processing device.

5. The information processing device according to claim 1, further comprising a control unit that displays display information for specifying the estimated position of the another information processing device on a display portion.

6. The information processing device according to claim 5, wherein the control unit displays information regarding a location at which the another information processing device is installed and the display information which are associated with each other.

7. The information processing device according to claim 5, wherein the control unit displays the display information so as to overlap an image generated by an imaging unit.

8. The information processing device according to claim 5, wherein the control unit displays at least one of a mark indicating a direction of the another information processing device in a case based on a position of the information processing device and a mark indicating a distance between the information processing device and the another information processing device, as the display information, on the display portion.

9. The information processing device according to claim 5,

wherein the estimation unit calculates reliability regarding the calculated direction of the another information processing device on the basis of the angle information, and

wherein the control unit changes a display mode of the display information on the basis of the calculated reliability.

10. The information processing device according to claim 1, further comprising a control unit that records communication state information in which the estimated position of the another information processing device and information regarding a state of wireless communication performed with the another information processing device are associated with each other.

11. The information processing device according to claim 1, further comprising a control unit that displays the estimated position of the another information processing device and information regarding a state of wireless communication performed with the another information processing device which are associated with each other.

12. The information processing device according to claim 1, further comprising a control unit that transmits information regarding the estimated position of the another information processing device to the another information processing device.

13. The information processing device according to claim 12, further comprising a positional information acquisition unit that acquires positional information regarding a position of the information processing device,

wherein the control unit calculates positional information regarding a position of the another information processing device on the basis of the acquired positional information and the estimated position of the another information processing device, and transmits the calculated positional information to the another information processing device.

14. The information processing device according to claim 1,

wherein the specific band is a high-frequency band, and

wherein the communication unit performs wireless communication using the high-frequency band with the another information processing device.

15. An information processing method comprising:

a communication procedure of performing wireless communication using a specific band with another information processing device; and

an estimation procedure of estimating a position of the another information processing device on the basis of information regarding a beam used at the time of the wireless communication.

16. A program causing a computer to execute:

a communication procedure of performing wireless communication using a specific band with another information processing device; and

an estimation procedure of estimating a position of the another information processing device on the basis of information regarding a beam used at the time of the wireless communication.
