Abstract

AR glasses includes one or more processors, and at least one of the one or more processors performs: receiving processing of receiving collision prediction information including location information about a dangerous area where a user is predicted to collide with a mobile object and information regarding a trajectory of the mobile object, from an external apparatus; determining processing of deriving a distance between the dangerous area and the user on the basis of the collision prediction information, to determine a danger level corresponding to the distance; generating processing of generating content that prompts danger avoidance depending on the danger level; and display control processing of displaying the content on a display.

Claims (22)

1. AR glasses worn by a user, comprising

one or more processors, wherein

at least one of the one or more processors performs:

receiving collision prediction information including location information about a dangerous area where the user is predicted to collide with a mobile object and information regarding a trajectory of the mobile object, from an external apparatus;

deriving a distance between the dangerous area and the user on the basis of the collision prediction information, to determine a danger level corresponding to the distance and being expressed as a percentage indicating a possibility of collision;

generating content that prompts danger avoidance in accordance with the danger level, wherein the generated content indicates a recommendation of danger avoidance when the danger level is less than a threshold value, and indicates that the mobile object is approaching the user when the danger level is equal to or greater than the threshold value; and

displaying the content on a display.

2. The AR glasses according to claim 1 , wherein the danger level increases as the distance decreases.

3. The AR glasses according to claim 1 , wherein the generated content that strongly reminds the user of a danger and danger avoidance as the danger level becomes higher.

4. The AR glasses according to claim 3 , wherein the generated content indicates moving away from the mobile object when the danger level is equal to or greater than a first threshold value and less than the threshold value, and indicates that the mobile object is approaching the user when the danger level is equal to or greater than the threshold value.

5. A control method performed by a communication apparatus, comprising:

receiving collision prediction information including location information about a dangerous area where a user wearing AR glasses is predicted to collide with a mobile object and information regarding a trajectory of the mobile object, from an external apparatus;

deriving a distance between the dangerous area and the user on the basis of the collision prediction information, to determine a danger level corresponding to the distance and being expressed as a percentage indicating a possibility of collision;

generating content that prompts danger avoidance in accordance with the danger level, wherein the generated content indicates a recommendation of danger avoidance when the danger level is less than a threshold value, and indicates that the mobile object is approaching the user when the danger level is equal to or greater than the threshold value; and

displaying the content on a display of the AR glasses.

6. A communication system comprising: a first apparatus; a second apparatus; and AR glasses, wherein each of the first apparatus, the second apparatus, and the AR glasses includes one or more processors, and at least one of the one or more processors performs:

processing in which the first apparatus detects a mobile object, generates collision prediction information including location information about a dangerous area where a user wearing the AR glasses is predicted to collide with the mobile object and information regarding a trajectory of the mobile object, and transmits the collision prediction information to the second apparatus;

processing in which the second apparatus receives the collision prediction information from the first apparatus, generates AR collision prediction information based on the collision prediction information, and transmits the AR collision prediction information to the AR glasses; and

processing in which the AR glasses receive the AR collision prediction information from the second apparatus, derive a distance between the dangerous area and the user on the basis of the AR collision prediction information, generate content that prompts danger avoidance in accordance with a danger level determined in accordance with the distance, and display the content on a display.

7. The communication system according to claim 6 , wherein processing in which the second apparatus further acquires a user attribute of the user, determines whether or not to transmit the AR collision prediction information to the AR glasses on the basis of the user attribute, and transmits the AR collision prediction information to the AR glasses when it is determined to transmit the AR collision prediction information, is further performed.

8. The communication system according to claim 7 , wherein the user attribute includes at least one of demographic information about the user or information about the user's usage of service provided by a web service.

9. The communication system according to claim 6 , wherein the first apparatus and the second apparatus are MEC servers.
