Abstract

A navigation system includes a database of a plurality of roads, a position determining system, an input device, and a route determination system. A CPU samples user inputs and a counter keeps track of the number of occurrences of those user inputs which achieve a particular user desired result. The CPU identifies the user inputs which achieve a particular result and stores such inputs within a user input database maintained in a storage device. The CPU continues to store the user inputs which achieve a desired user result until a predetermined number of “N” occurrences is reached. After reaching the “N” number of occurrences, it has become apparent that this is not an infrequent inefficient input by the user. The CPU will then display a suggestion screen which provides a predetermined suggested input tailored to the prior inefficient user inputs.

Claims

1. A vehicle navigation system comprising:

a database including a plurality of roads;

a user input device for selecting a desired destination relative to said database of roads;

a CPU for sampling a plurality of user inputs to said user input device which achieve a result, said CPU determining an efficiency of said plurality of user inputs in relation to said result; and

a display for displaying a predetermined suggested input to achieve said result if said efficiency is below a predetermined efficiency.

2. A vehicle navigation system as recited in claim 1, wherein said result includes a particular vehicle navigation system feature activation.

3. A vehicle navigation system as recited in claim 1, wherein said result includes a symbol selection.

4. A vehicle navigation system as recited in claim 1, wherein said predetermined efficiency is stored within said database in relation to said result.

5. A vehicle navigation system as recited in claim 1, further includes a counter, said efficiency including said counter being increased in relation to said plurality of user inputs and said result, said display displaying said predetermined suggested input if said counter exceeds a predetermined quantity.

6. A vehicle navigation system as recited in claim 1, further includes a timer, said efficiency including said timer being increased in relation to a continued series of said plurality of user inputs.

7. A vehicle navigation system as recited in claim 1, wherein said predetermined suggested input is stored as a table within said database.

8. A vehicle navigation system as recited in claim 7, wherein said predetermined suggested input includes a plurality of suggested inputs, said plurality of suggested inputs being less than said plurality of user inputs.

9. A vehicle navigation system as recited in claim 7, wherein said predetermined suggested input includes a single suggested input that replaces said plurality of user inputs.

10. A vehicle navigation system as recited in claim 1, further comprising an audio speaker, said CPU generating an audio predetermined suggested input in association with said display displaying said predetermined suggested input.

11. A vehicle navigation system as recited in claim 1, wherein said display displays an instructional text in association with said predetermined suggested input.

12. A vehicle navigation system as recited in claim 11, wherein said predetermined suggested input is associated to a category of information request displayed on said display during which said timer exceeds said predetermined time period.

13. A vehicle navigation system as recited in claim 11, wherein said timer is predetermined time period is included in calculating a user efficiency.

14. A vehicle navigation system comprising:

a database including a plurality of roads;

a user input device for selecting a desired destination relative to said database of roads;

a CPU for recognizing a user input to said user input device; and

a display for displaying a predetermined suggested input if a timer exceeds a predetermined time period during which no user inputs are recognized by said CPU.

15. A method for instructing a navigation system user including the steps of:

(a) sampling a plurality of user inputs which achieve a result;

(b) determining an efficiency of said plurality of user inputs in relation to said result; and

(c) displaying a predetermined suggested input to achieve said result if said efficiency determined in said step (b) is below a predetermined efficiency.

16. A vehicle navigation system as recited in claim 15, wherein said predetermined suggested input includes a plurality of suggested inputs.

17. A vehicle navigation system as recited in claim 15, wherein said predetermined suggested input includes a single suggested input that replaces said plurality of user inputs.

18. The method of claim 15 wherein said step (b) includes counting each of said plurality of user inputs.

19. The method of claim 15 wherein said efficiency is related to a quantity of said plurality user inputs.

20. The method of claim 19 wherein said counting is reinitiated if said plurality of user inputs is equivalent to said suggested input.

21. The method of claim 20 wherein said efficiency is related to a predetermined quantity of a user set.

22. The method of claim 15 wherein said efficiency is related to a time period during which a continued series of said plurality of user inputs is entered.

23. The method of claim 22 wherein said predetermined efficiency is related to said time period.

24. The method of claim 15 wherein said predetermined efficiency is related to said suggested input.

25. The method of claim 15 wherein said step (b) includes defining each of said plurality of user inputs which achieve said result as a single user set.

26. The method of claim 25 wherein said step (b) includes counting each user set.
