Abstract

Provided is an information processing device comprising: a processing unit that dynamically sets an area in a portion of the surroundings of a first terminal including the position of the first terminal on the basis of a state of a moving body mounting the first terminal and the position of the first terminal and determines entry of a second terminal into or approach of the second terminal to the area; and a communication unit that transmits, to the second terminal, a signal for causing the second terminal to issue an alarm in response to the entry or the approach.

First claim

The invention claimed is:

1 . An information processing apparatus comprising:
a processor that dynamically sets an area somewhere around a first terminal including a position of the first terminal based on a state of a mobile object on which the first terminal is mounted and the position of the first terminal and that determines entry or approach of a second terminal to the area; and a communicator that transmits, to the second terminal, a signal for causing the second terminal to output an alarm for the entry or the approach, wherein the state of the mobile object is a state of movement of the mobile object, wherein the processor sets the area such that a part of the area corresponding to a travel direction of the mobile object becomes larger than a part of the area opposite the part corresponding to the travel direction of the mobile object across the mobile object, and wherein a size of a part of the area opposite the part corresponding to the travel direction of the mobile object across the mobile object being greater than zero.

2 . The information processing apparatus according to claim 1 ,
wherein, when the mobile object is traveling forward, the processor sets the area including a first part ahead of the mobile object and a second part, which is smaller than the first part, behind the mobile object, and wherein, when the mobile object is traveling backward, the processor sets the area including a third part behind the mobile object and a fourth part, which is smaller than the third part, ahead of the mobile object.

3 . The information processing apparatus according to claim 1 ,
wherein, when the mobile object is turning, the processor sets the area such that a part of the area inside the turn becomes larger than a part of the area outside the turn.

4 . The information processing apparatus according to claim 1 ,
wherein the state of the mobile object is a state of movement of a movable part that is included in the mobile object and that moves without accompanying movement of the mobile object.

5 . The information processing apparatus according to claim 4 ,
wherein, when a tip of the movable part is rotating, the processor sets the area such that a part of the area inside the rotation becomes larger than a part of the area outside the rotation.

6 . The information processing apparatus according to claim 5 ,
wherein the processor adjusts size of the area in accordance with at least one of rotation speed and/or reach of the tip of the movable part.

7 . The information processing apparatus according to claim 6 ,
wherein, when the movable part is moving while the mobile object is moving, the processor sets the area such that the area becomes larger than when the movable part is moving while the mobile object is stationary.

8 . An information processing apparatus comprising:
a processor that dynamically sets an area somewhere around a first terminal including a position of the first terminal based on a state of a mobile object on which the first terminal is mounted and the position of the first terminal and that determines entry or approach of a second terminal to the area; and a communicator that transmits, to the second terminal, a signal for causing the second terminal to output an alarm for the entry or the approach, wherein the communicator transmits a signal for causing the second terminal that has not been determined to be entering the area before the state of the mobile object changed but that is determined to be entering the area as a result of the change in the state of the mobile object to output an alarm different from an alarm for the second terminal that has been determined to be entering the area before and after the change in the state of the mobile object.

9 . The information processing apparatus according to claim 1 ,
wherein the communicator receives, from the second terminal, a position of the second terminal determined based on Real-Time Kinematic (RTK) processing.

10 . The information processing apparatus according to claim 1 ,
wherein the processor determines a position of the second terminal based on RTK processing.

11 . The information processing apparatus according to claim 1 ,
wherein the communicator transmits, to the first terminal, a signal for causing the first terminal to output an alarm for the entry or the approach.

12 . An information processing method performed by an information processing apparatus, the information processing method comprising:
dynamically setting an area somewhere around a first terminal including a position of the first terminal based on a state of a mobile object on which the first terminal is mounted and the position of the first terminal; determining entry or approach of a second terminal to the area; and transmitting, to the second terminal, a signal for causing the second terminal to output an alarm for the entry or the approach, wherein the state of the mobile object is a state of movement of the mobile object, wherein the area is set such that a part of the area corresponding to a travel direction of the mobile object becomes larger than a part of the area opposite the part corresponding to the travel direction of the mobile object across the mobile object, and wherein a size of a part of the area opposite the part corresponding to the travel direction of the mobile object across the mobile object being greater than zero.

13 . An alarm system, comprising:
a first terminal; and a second terminal, wherein the alarm system dynamically sets an area somewhere around the first terminal including a position of the first terminal based on a state of a mobile object on which the first terminal is mounted and the position of the first terminal, wherein the alarm system determines entry or approach of the second terminal to the area, wherein the alarm system performs at least one of processing for transmitting, to the first terminal, a first signal for causing the first terminal to output a first alarm and processing for transmitting, to the second terminal, a second signal for causing the second terminal to output a second alarm, wherein the first terminal outputs the alarm in accordance with the first signal, wherein the second terminal outputs the alarm in accordance with the second signal, wherein the state of the mobile object is a state of movement of the mobile object, wherein the alarm system sets the area such that a part of the area corresponding to a travel direction of the mobile object becomes larger than a part of the area opposite the part corresponding to the travel direction of the mobile object across the mobile object, and wherein a size of a part of the area opposite the part corresponding to the travel direction of the mobile object across the mobile object being greater than zero.

14 . An information processing method performed by an information processing apparatus, the information processing method comprising:
dynamically setting an area somewhere around a first terminal including a position of the first terminal based on a state of a mobile object on which the first terminal is mounted and the position of the first terminal; determining entry or approach of a second terminal to the area; and transmitting, to the second terminal, a signal for causing the second terminal to output an alarm for the entry or the approach, wherein the communicator transmits a signal for causing the second terminal that has not been determined to be entering the area before the state of the mobile object changed but that is determined to be entering the area as a result of the change in the state of the
