Abstract

The present invention provides a navigation device that improves the usability. The navigation device includes an evaluation setting unit that generates position information having first evaluation value by setting an evaluation value selected by a user so that the evaluation value corresponds to position information, a position information extraction unit that extracts, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the evaluation value desired by the user, and a display control unit that displays a position information screen having evaluation value on which the position information having the first evaluation value extracted by the position information extraction unit is reflected on a display unit.

Claims

1. A navigation device comprising:

evaluation setting means for generating position information having first evaluation value by setting an evaluation value selected by a user so that the evaluation value corresponds to position information;

position information extraction means for extracting, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the evaluation value desired by the user; and

display control means for displaying a position information screen having evaluation value on which the position information having the first evaluation value extracted by the position information extraction means is reflected on display means.

2. The navigation device according to claim 1, wherein

the evaluation setting means generates the position information having the first evaluation value by setting an itemized evaluation value with respect to a plurality of respective items preset in the position information, and

the position information extraction means extracts, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the itemized evaluation value desired by the user.

3. The navigation device according to claim 2, wherein

the position information extraction means extracts, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the plural itemized evaluation values desired by the user.

4. The navigation device according to claim 2, further comprising

overall evaluation calculation means for calculating the overall evaluation value of the position information having the first evaluation value according to the plural itemized evaluation values set for the position information having the first evaluation value by the evaluation setting means, wherein

the position information extraction means extracts, of the position information having the first evaluation value for which the overall evaluation value is calculated by the overall evaluation calculation means, the position information having the first evaluation value corresponding to the overall evaluation value desired by the user.

5. The navigation device according to claim 1, further comprising

obtaining means for obtaining position information having second evaluation value for which the average value of the evaluation values selected by a plurality of users is set from the outside, wherein

the position information extraction means extracts, of the position information having the second evaluation value, the position information having the second evaluation value of the evaluation value desired by the user.

6. The navigation device according to claim 5, wherein

the position information having the second evaluation value is described in the Rich Site Summary (RSS) in the Extensible Markup Language (XML) format.

7. The navigation device according to claim 1, further comprising

accession route calculation means for calculating the accession route to the destination, wherein

the position information extraction means extracts, of the position information having the first evaluation value, the position information having the first evaluation value which is the evaluation value desired by the user, and is located near the accession route.

8. An evaluation value setting method, comprising:

an evaluation setting step of generating position information having first evaluation value by setting an evaluation value selected by a user so that the evaluation value corresponds to position information using evaluation setting means;

a position information extraction step of extracting, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the evaluation value desired by the user using position information extraction means; and

a display control step of displaying a position information screen having evaluation value on which the position information having the first evaluation value extracted by the position information extraction means is reflected on display means using display control means.

9. The evaluation value setting method according to claim 8, wherein

the evaluation setting step generates the position information having the first evaluation value by setting an itemized evaluation value with respect to a plurality of respective items preset in the position information, and

the position information extraction step extracts, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the itemized evaluation value desired by the user.

10. The evaluation value setting method according to claim 9, wherein

the position information extraction step extracts, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the plural itemized evaluation values desired by the user.

11. The evaluation value setting method according to claim 9, further comprising

an overall evaluation calculation step of calculating the overall evaluation value of the position information having the first evaluation value according to the plural itemized evaluation values set for the position information having the first evaluation value in the evaluation setting step, wherein

the position information extraction step extracts, of the position information having the first evaluation value for which the overall evaluation value is calculated in the overall evaluation calculation step, the position information having the first evaluation value corresponding to the overall evaluation value desired by the user.

12. The evaluation value setting method according to claim 8, further comprising

an obtaining step of obtaining position information having second evaluation value for which the average value of the evaluation values selected by a plurality of users is set from the outside, wherein

the position information extraction step extracts, of the position information having the second evaluation value, the position information having the second evaluation value of the evaluation value desired by the user.

13. The evaluation value setting method according to claim 12, wherein

the position information having the second evaluation value is described in the Rich Site Summary (RSS) in the Extensible Markup Language (XML) format.

14. The evaluation value setting method according to claim 8, further comprising

an accession route calculation step of calculating the accession route to the destination, wherein

the position information extraction step extracts, of the position information having the first evaluation value, the position information having the first evaluation value which is the evaluation value desired by the user, and is located near the accession route.

15. A navigation device comprising:

an evaluation setting unit that generates position information having first evaluation value by setting an evaluation value selected by a user so that the evaluation value corresponds to position information;

a position information extraction unit that extracts, of the position information having the first evaluation value, the position information having the first evaluation value corresponding to the evaluation value desired by the user; and

a display control unit that displays a position information screen having evaluation value on which the position information having the first evaluation value extracted by the position information extraction unit is reflected on a display unit.
