Abstract

In a vehicle-mounted display system, a spare attentiveness level deriving part derives a spare attentiveness level that is a parameter determined according to a state of a driver of a vehicle at a present moment and a risk level deriving part derives a risk level that is a parameter determined according to a risk level of an accident at the present moment. Then a display continuously displays a driving state mark that is a reference graphic, determined according to the spare attentiveness level and the risk level, while the driver is driving the vehicle. Therefore, the driver can continuously understand the own state and the risk level of an accident at the present moment.

Claims

1. A display control apparatus that controls a display apparatus for providing information to a driver of a vehicle while the driver is driving the vehicle, the display control apparatus comprising a controller that:

(i) derives a first parameter according to a state of the driver at a present moment;

(ii) derives a second parameter according to a risk level of an accident at the present moment; and

(iii) causes a reference graphic, determined according to the first parameter and the second parameter, to be continuously displayed on the display apparatus while the driver is driving the vehicle.

2. The display control apparatus according to claim 1, wherein

the reference graphic represents a relative relationship between the first parameter and the second parameter.

3. The display control apparatus according to claim 2, wherein

the reference graphic represents the relative relationship between the first parameter and the second parameter with color.

4. The display control apparatus according to claim 2, wherein

the reference graphic represents the relative relationship between the first parameter and the second parameter by a ratio of areas.

5. The display control apparatus according to claim 1, wherein

the controller derives the first parameter based on a difference between (a) a load acceptable capacity that represents a load acceptable by the driver at the present moment and (b) a present load exerted on the driver at the present moment.

6. The display control apparatus according to claim 5, wherein

the reference graphic represents the load acceptable capacity along with a relative relationship between the first parameter and the second parameter.

7. The display control apparatus according to claim 6, wherein

the reference graphic represents the load acceptable capacity by controlling a size of an outer edge of the reference graphic.

8. The display control apparatus according to claim 5, wherein

the controller derives the present load based on a determination as to whether or not a content provided to the driver matches a taste of the driver.

9. A display system that provides information to a driver of a vehicle while the driver is driving the vehicle, the display system comprising:

a controller that;

(i) derives a first parameter according to a state of the driver at a present moment; and

(ii) derives a second parameter according to a risk level of an accident at the present moment; and

a display that continuously displays a reference graphic, determined according to the first parameter and the second parameter, while the driver is driving the vehicle.

10. An information providing method that provides information to a driver of a vehicle while the driver is driving the vehicle, the information providing method comprising the steps of:

(a) deriving a first parameter according to a state of the driver at a present moment;

(b) deriving a second parameter according to a risk level of an accident at the present moment; and

(c) causing a reference graphic, determined according to the first parameter and the second parameter, to be continuously displayed on a display apparatus while the driver is driving the vehicle.

11. A non-transitory computer-readable recording medium that stores a program to be executed by a computer for providing information to a driver of a vehicle while the driver is driving the vehicle, the program causing the computer to execute the steps of:

(a) deriving a first parameter according to a state of the driver at a present moment;

(b) deriving a second parameter according to a risk level of an accident at the present moment; and

(c) causing a reference graphic, determined according to the first parameter and the second parameter, to be continuously displayed on a display apparatus while the driver is driving the vehicle.
