Abstract: Provided is a communication apparatus including: a target specification unit for specifying a position of a target at risk of approaching a moving body; and a communication unit for transmitting, based on the target position specified by the target specification unit, warning information including positional information of an external terminal to output a warning; a program causing a computer to function as: a target specification unit for specifying a position of a target at risk of approaching a moving body; and a communication unit for transmitting, based on the target position specified by the target specification unit, warning information including positional information of an external terminal to output a warning; and a communication method including: specifying a position of a target at risk of approaching a moving body; and transmitting, based on the specified target position, warning information including positional information of an external terminal to output a warning.

Abstract: A communication device includes a target locating unit configured to locate a position of a target having a risk of approaching a moving body. The communication device includes a transmission unit configured to transmit request information including positional information of an external terminal, for which the positional information is requested, based on the position of the target located by the target locating unit. The communication device includes a reception unit configured to receive response information with respect to the request information. The transmission unit is configured to transmit warning information based on the positional information of the external terminal included in the response information.

Abstract: A display device 10 of a vehicle includes a first display section 15, a second display section 16, a steering switch 11, a vehicle speed sensor 12, and a control device 17. The first display section 15 displays at least a map. The second display section 16 displays information for operating a display content of the first display section 15. The steering switch 11 receives an operation input of an operator of the vehicle 1. The vehicle speed sensor 12 detects speed of the vehicle. The control device 17 displays information of an operation state of the steering switch 11 on the second display section 16 when the vehicle speed which is detected by the vehicle speed sensor 12 is larger than a threshold value.
