Abstract

An information display apparatus, including a nonvolatile database memory 14 that stores map data, a display unit 16, a user state detection unit 31 that detects a kind of user movement state indicative of a current user movement state from among a plurality of kinds of user movement states, a display setting unit 32 that sets a display form of the map data to be displayed by the display unit based on the user movement state detected by the user state detection unit, and a display control unit 33 that controls a display of the map data by the display unit in the display form set by the display setting unit.

Claims

1. An information display apparatus, comprising:

a storage unit that stores map data;

a display unit;

a user state detection unit that detects a user movement state indicative of a current user movement state;

a display setting unit that sets a display form of the map data to be displayed by the display unit based on the user movement state detected by the user state detection unit; and

a display control unit that controls a display of the map data by the display unit in the display form set by the display setting unit.

2. An information display apparatus as set forth in claim 1, further comprising an acceleration sensor, wherein

the user state detection unit calculates a vibration frequency on the basis of an output from the acceleration sensor, and detects a kind of user movement state indicative of a current user movement state based on the vibration frequency in a vertical direction.

3. An information display apparatus as set forth in claim 1, further comprising an acceleration sensor, wherein

the user state detection unit detects a kind of user movement state indicative of a current user movement state based on an amplitude on the basis of an output from the acceleration sensor.

4. An information display apparatus as set forth in claim 1, wherein

the display setting unit sets a scale of a map to be displayed under control of the display control unit, based on a detection result detected by the user state detection unit.

5. An information display apparatus as set forth in claim 1, wherein

the display setting unit sets character size in a map to be displayed under control of the display control unit, based on a detection result of the user state detection unit.

6. An information display apparatus as set forth in claim 1, wherein

the display control unit executes control of displaying the map on a display unit illuminated by a backlight, and

the display setting unit sets a lighting condition of the backlight based on a detection result of the user state detection unit.

7. An information display apparatus as set forth in claim 1, further comprising a location information acquiring unit that acquires location information indicative of a current location of the information display apparatus, wherein

the display setting unit sets a display form of a map including a current location specified by the location information acquired by the location information acquiring unit.

8. An information display method of an information display apparatus that displays map data stored in a storage unit on a display unit, the method comprising:

a user state detection step of detecting a user movement state indicative of a current user movement state;

a display setting step of setting a display form of the map data to be displayed by the display unit based on the user movement state detected in the user state detection step; and

a display control step of controlling a display of the map data by the display unit in the display form set in the display setting step.

9. A storage medium having stored therein a program causing a computer that controls an information display apparatus that displays map data stored in a storage unit on a display unit to implement:

a user state detection function that detects a kind of user movement state indicative of a current user movement state;

a display setting function that sets a display form of the map data to be displayed by the display unit based on the user movement state detected by the user state detection function; and

a display control function that controls a display of the map data by the display unit in the display form set by the display setting function.
