Abstract

A navigation apparatus which accepts an operation of an operation button displayed on a display part, the navigation apparatus including: a vehicle operation detector detecting a vehicle operation when the vehicle travels; a driver characteristics learning mechanism learning driver characteristics of a driver based on the driver operation information; and a display manner changing mechanism changing a display manner of the operation button according to a learning result of the driver characteristics learning mechanism.

Claims

1. A navigation apparatus which accepts an operation of an operation button displayed on a display part, said navigation apparatus comprising:

vehicle operation detecting means for detecting a vehicle operation;

vehicle operation obtaining means for obtaining driver operation information based on the vehicle operation which the vehicle operation detecting means detects;

driver characteristics learning means for learning driver characteristics of a driver based on the driver operation information; and

display manner changing means for changing a display manner of the operation button according to a learning result of the driver characteristics learning means.

2. The navigation apparatus claimed in claim 1, further comprising:

vehicle circumstance detecting means for detecting a vehicle circumstance at the time of traveling; and

circumstance information obtaining means for obtaining vehicle circumstance information based on the vehicle circumstance which the vehicle circumstance detecting means detects, wherein

the driver learning means learns the driver characteristics of the driver based on the driver operation information in a predetermined vehicle circumstance.

3. The navigation apparatus claimed in claim 1, wherein in the case of plural operation buttons being displayed,

the display manner changing means displays, based on the learning result, the operation buttons in such a manner that the operation buttons whose number is less than the number of the operation buttons in an initial setting displayed at the time of traveling is displayed in a selectable manner.

4. The navigation apparatus claimed in claim 1, wherein in the case of plural operation buttons being displayed,

the display manner changing means displays, based on the learning result, the operation buttons in such a manner that the operation button, which is not selectable by a passenger, among the operation buttons in an initial setting displayed at the time of traveling is displayed in less tone than the operation button which is selectable.

5. The navigation apparatus claimed in claim 1, wherein in the case of plural operation buttons being displayed,

the display manner changing means displays, based on the learning result, the operation buttons in such a manner that the operation buttons whose number is more than the number of the operation buttons in an initial setting displayed at the time of traveling is displayed in a selectable manner.

6. The navigation apparatus claimed in claim 3, wherein the driver characteristics learning means learns a degree of momentary lapses of attention or a degree of haste of the driver,

the display manner changing means displays in such a manner that the greater the degree of momentary lapses of attention or the degree of haste becomes, the less number of the operation buttons is displayed in a selectable manner.

8. The navigation apparatus claimed in claim 1, wherein the vehicle operation for driving a vehicle is a vehicle operation of accelerating, decelerating or steering, or a vehicle operation at the time of traveling required in terms of statute or safety.

9. The navigation apparatus claimed in claim 1, wherein

the vehicle operation detecting means detects an operation of the operation button, and

the vehicle operation obtaining means obtains the driver operation information based on the operation of the operation button which the vehicle operation detecting means detects.

10. The navigation apparatus claimed in claim 9, wherein the driver characteristics learning means learns the driver characteristics of the driver by converting a frequency of the operation of the operation button into numbers.

7. An operation part display method for a navigation apparatus which accepts an operation of an operation button displayed on a display part, said navigation apparatus comprising:

a step in which vehicle operation detecting means detects a vehicle operation;

a step in which vehicle operation obtaining means obtains driver operation information based on the vehicle operation which the vehicle operation detecting means detects;

a step in which driver characteristics learning means learns driver characteristics of a driver based on the driver operation information; and

a step in which display manner changing means changes a display manner of the operation button according to a learning result of the driver characteristics learning means.
