Information display device and information display method
A vehicle state determining unit ( 1 ) for determining a state of a vehicle, a display data output unit ( 7 ) for outputting display data for displaying information indicating the state of the vehicle determined by the vehicle state determining unit ( 1 ), and an information displaying unit ( 10 ) for determining display time of the information from the state of the vehicle determined by the vehicle state determining unit ( 1 ) and displaying the information to the outside of the vehicle in accordance with the display data output from the display data output unit ( 7 ) during the display time, in which the information displaying unit ( 10 ) is configured to switch a display method of the information in accordance with the display time. Thus, a degree of information transmission may be increased.
1. An information display device, comprising:
a processor; and
a memory storing instructions which, when executed by the processor, causes the processor to:
determine a state of a vehicle including a traveling direction of the vehicle and a speed of the vehicle;
output display data for displaying information indicating the determined state of the vehicle;
determine a target to which the information is presented; and
determine display time period of the information from the determined state of the vehicle and the determined target to which the information is presented, and display the information to an outside of the vehicle in accordance with the output display data during the display time,
wherein the processor selects a projection surface of the information in accordance with the determined display time period.
2. The information display device according to claim 1 ,
wherein the processor further
detects a relative state between a user's vehicle and the target to which the information is presented,
wherein the processor corrects the display time using the detected relative state.
3. The information display device according to claim 1 ,
wherein the processor determines the relative state between the user's vehicle and the target to which the information is presented as the state of the vehicle.
4. An information display device, comprising:
a processor; and
a memory storing instructions which, when executed by the processor, causes the processor to:
determine a state of a vehicle including a traveling direction of the vehicle and a speed of the vehicle;
output display data for displaying information indicating the determined state of the vehicle; and
determine a display time period of the information from the determined state of the vehicle and display the information to an outside of the vehicle in accordance with the output display data during the determined display time period,
wherein the processor displays the information indicating the state of the vehicle on a projection surface by irradiating the projection surface outside the vehicle with light in accordance with the output display data and
select at least one of the projection surface and a type of the light irradiated to the projection surface in accordance with the determined display time period.
5. The information display device according to claim 1 ,
wherein the processor further:
monitors a situation around the vehicle and controlling display of the information in accordance with a monitoring result of the situation.
6. The information display device according to claim 1 ,
wherein the processor further:
processes the output display data in accordance with the state of the vehicle,
wherein the processor displays the information to the outside of the vehicle in accordance with the processed display data.
7. An information display method, comprising:
determining, by a vehicle state determining unit, a state of a vehicle including a traveling direction of the vehicle and a speed of the vehicle;
outputting, by a display data output unit, display data for displaying information indicating the state of the vehicle determined by the vehicle state determining unit;
determining, by a presentation target determining unit, a target to which the information is presented;
determining, by an information displaying unit, a display time period of the information from the state of the vehicle determined by the vehicle state determining unit and the presentation target determined by the presentation target determining unit, and
displaying, by the information displaying unit, the information to an outside of the vehicle in accordance with the display data output from the display data output unit during the determined display time period; and
selecting, by the information displaying unit, a projection surface of the information in accordance with the determined display time period.
8. An information display method, comprising:
determining, by a vehicle state determining unit, a state of a vehicle including a traveling direction of the vehicle and a speed of the vehicle;
outputting, by a display data output unit, display data for displaying information indicating the state of the vehicle determined by the vehicle state determining unit;
determining, by an information displaying unit, a display time period of the information from the state of the vehicle determined by the vehicle state determining unit and
displaying, by the information displaying unit, the information to an outside of the vehicle in accordance with the display data output from the display data output unit during the determined display time period;
displaying, by a light irradiation unit included in the information displaying unit, information indicating the state of the vehicle on a projection surface by irradiating the projection surface outside the vehicle with light in accordance with the display data output from the display data output unit; and
selecting, by the light irradiation unit, at least one of the projection surface and a type of the light irradiated to the projection surface in accordance with the determined display time period.
