Abstract

The object of the present invention is to enable presentation of information on a target object (vehicle) located on a road to a pedestrian at an appropriate time and such that the information includes appropriate information for the pedestrian's statues. A pedestrian device transmits position data of a pedestrian to an in-vehicle device, which determines whether or not the pedestrian approaches a vehicle based on the position data. When determining that the pedestrian approaches the vehicle, the in-vehicle device transmits guidance direction information to the pedestrian device. The pedestrian device performs control based on the guidance direction information so as to guide the pedestrian to look toward the vehicle, and the pedestrian device acquires sight status information of the pedestrian from a wearable terminal and transmits the sight status information to the in-vehicle terminal. Then, the in-vehicle terminal determines whether or not the pedestrian sees the vehicle. When determining that the pedestrian does not see the vehicle, the in-vehicle terminal transmit alert information to the pedestrian terminal, and the pedestrian terminal performs control based on the alert information so as to provide an alert to the pedestrian.

First claim

The invention claimed is:

1. A pedestrian device, comprising:
a communication transceiver configured to communicate with a communication device which transmits information of a target object to be paid attention by a pedestrian; and
a controller,
wherein the controller is configured to cause the communication transceiver to transmit position data of the pedestrian to the communication device;
wherein the communication device is configured to transmit guidance direction information to the communication transceiver when the pedestrian approaches to within a predetermined distance from the target object;
wherein, when the communication transceiver receives the guidance direction information transmitted from the communication device, the controller is configured to
perform control based on the guidance direction information so as to guide the pedestrian to look in a direction toward the target object; and
acquire sight status information on a sight status of the pedestrian, and cause the communication transceiver to transmit the sight status information to the communication device; and

wherein, when the communication device transmits, based on the sight status information, target object information on the target object to the communication transceiver, and then the communication transceiver receives the target object information, the controller performs control so as to present the target object information to the pedestrian.

2. The pedestrian device according to claim 1 , wherein the communication device is an in-vehicle device mounted in a vehicle;
wherein the target object is the vehicle in which the in-vehicle device is mounted;
wherein, when determining that the pedestrian does not see the vehicle, the in-vehicle device transmits alert information to the pedestrian device; and
wherein, when receiving the alert information transmitted from the in-vehicle device, the controller performs control based on the alert information so as to provide an alert to the pedestrian.

3. The pedestrian device according to claim 2 , further comprising a short-range communication transceiver configured to perform short-range communications with a wearable device, wherein the wearable device is configured to be worn on a body of the pedestrian and detect the sight status of the pedestrian; and
wherein the controller is configured to acquire the sight status of the pedestrian from the wearable device.

4. The pedestrian device according to claim 3 , wherein the wearable device is worn by the pedestrian on a head, and measures a head orientation of the pedestrian and a viewer-to-target distance from a viewpoint of the pedestrian to the target object, as the sight status information; and
wherein the controller is configured to transmit the head orientation and the viewer-to-target distance to the in-vehicle device.

5. The pedestrian device according to claim 3 , wherein the wearable device includes a vibrator, a speaker, and a display; and wherein the controller is configured to control at least one selected from the group consisting of the vibrator, the speaker, and the display of the wearable device so as to guide the pedestrian to look in the direction toward the vehicle.

6. The pedestrian device according to claim 3 , wherein the controller is configured to cause a display included in the wearable device to display a virtual vehicle image.

7. The pedestrian device according to claim 1 , wherein the communication device is a roadside device installed on a road;
wherein the target object is an advertisement object;
wherein, when determining that the pedestrian sees the advertisement object, the roadside device transmits advertisement object information on the advertisement object to the pedestrian device; and
wherein, when receiving the advertisement object information transmitted from the roadside device, the controller performs control so as to present the advertisement object information to the pedestrian.

8. The pedestrian device according to claim 1 , wherein the communication device is an in-vehicle device which is mounted in an advertisement vehicle used as an advertisement object;
wherein, when determining that the pedestrian sees the advertisement vehicle, the in-vehicle device transmits advertisement vehicle information on the advertisement vehicle to the pedestrian device; and
wherein, when receiving the advertisement vehicle information transmitted from the in-vehicle device, the controller performs control so as to present the advertisement vehicle information to the pedestrian.

9. The pedestrian device according to claim 7 , further comprising a short-range communication transceiver configured to perform short-range communications with a wearable device, wherein the wearable device is configured to be worn on a body of the pedestrian and detect the sight status of the pedestrian; and
wherein the controller is configured to acquire the sight status of the pedestrian from the wearable device.

10. The pedestrian device according to claim 9 , wherein the wearable device includes a vibrator, a speaker, and a display; and wherein the controller is configured to control at least one selected from the group consisting of the vibrator, the speaker, and the display of the wearable device so as to guide the pedestrian to look in the direction toward the vehicle.

11. A communication device installed near a target object to be paid attention, the target object being located on or around a road, and configured to deliver target object information on a target object to be paid attention by a pedestrian, the communication device comprising:
a communication transceiver configured to communicate with a pedestrian device; and
a controller,
wherein, when the communication transceiver receives position data of the pedestrian transmitted from the pedestrian device, the controller determines whether or not the pedestrian approaches to within a predetermined distance from the target object based on the position data of the pedestrian;
wherein, when determining that the pedestrian approaches to within the predetermined distance from the target object, the controller causes the communication transceiver to transmit guidance direction information to the pedestrian device, such that the pedestrian device uses the guidance direction information to guide the pedestrian to look in a direction toward the target object; and
wherein, when the communication transceiver receives sight status information on a sight status of the pedestrian, the controller determines, based on the sight status information, whether or not the pedestrian sees the target object, and then, based on a determination result, the controller transmits target object information to the pedestrian device.

12. The communication device according to claim 11 , wherein the communication device is an in-vehicle device mounted in a vehicle;
wherein the target object is the vehicle, in which the in-vehicle device is mounted; and
wherein, when determining that the pedestrian does not see the vehicle, the controller causes the communication transceiver to transmit alert information to the pedestrian device, the alert information providing an alert to the pedestrian.

13. The communication device according to claim 12 , wherein, when the pedestrian sees the vehicle, the controller does not cause the communication transceiver to transmit the alert information.

14. The communication device according to claim 12 , wherein the pedestrian device transmits a head orientation of the pedestrian and a viewer-to-target distance from a viewpoint of the pedestrian to the target object, as the sight stat
