Abstract

A navigation system having a destination selection input mechanism that can be readily and rapidly used by an inexperienced user. The display (103) and user input (102) are physically configured and controllably intercoupled to support the conveyance of an impression to the inexperienced user that the information displayed can be selectively altered one field at a time in a precessing manner through appropriate use of the input unit (102). In one embodiment, selection of information for one field as pertains to a particular desired location destination will limit the information values that can be selected for remaining unselected information fields.

Claims

1. In a navigation system for use with a moving object, wherein the navigation system includes stored potential destination location information, an improvement wherein:

A) information for each potential destination location is comprised of a plurality of information fields; and

B) the navigation system further includes means for specifying desired destination information in conjunction with a user, comprising;

i) display means for displaying information;

ii) first input means responsive to the user for receiving user input and for causing the display means to display selected information regarding one of the information fields;

iii) second input means responsive to the user for subsequently receiving different user input and for causing the display means to subsequently display selected information regarding a different one of the information fields;

iv) control means responsive to both the first and second input means, for limiting information that can be selected for display on the display means by the second input means from a first set of information item stored within the navigation system to a smaller second set of information items contained within the first set of information items as a function, at least in part, of information selected by the first input means.

2. The improvement of claim 1 wherein the display means has display areas that are segregated from one another and that are each reserved for displaying information from a preselected information field only.

3. The improvement of claim 2 wherein the first input means includes a user operable switch that is positioned substantially proximal to the segregated display area that corresponds to the information field preassociated with the first input means.

4. The improvement of claim 3 wherein the second input means includes a user operable switch that is positioned substantially proximal to the segregated display area that corresponds to the information field preassociated with the second input means.

5. The improvement of claim 1 wherein the information fields each include discrete elements of a potential destination location address.

6. The improvement of claim 5 wherein the control means limits selection of subsequent discrete address elements as a function, at least in part, of previously selected discrete address elements, such that selected discrete address elements cannot be combined to thereby yield a nonexistent potential destination location.

7. The improvement of claim 5 wherein at least one of the discrete elements comprises a telephone number.

8. The improvement of claim 5 wherein at least one of the discrete elements comprises a zip-code.

9. The improvement of claim 5 wherein at least one of the discrete elements comprises a landmark identifier.

10. The improvement of claim 5 wherein at least one of the discrete elements comprises street intersection information.

11. The improvement of claim 5 wherein at least one of the discrete elements comprises a user entered alias.

12. The improvement of claim 5 wherein at least one of the discrete elements comprises an alias for the potential destination location.

13. A method of selecting a destination in a computer based navigation system, wherein the navigation system includes a stored first set of information items including potential destination location information, and location information for each potential destination is comprised of a plurality of information fields;

the method comprising the steps of;

A) displaying on a display at least some of the information fields;

B) selecting a specific information value from the first set of information items for one information field;

C) in the computer, automatically limiting, for at least one other information field, information values that can be subsequently selected from the first set of information items to a smaller second set of information items contained within the first set of information items as a function, at least in part, of the specific information value so selected;

D) selecting a specific non-limited information value for the at least one other information field.

14. The method of claim 13 wherein the step of displaying at least some of the information fields includes the step of display different information fields in display areas segregated from one another.

15. The method of claim 13 wherein at least some of the information fields include information that comprises discrete elements of a potential destination address.

16. The method of claim 15 wherein the step of limiting includes the step of limiting, for at least one other information field that comprises a discrete element of a potential destination address, other discrete elements that can be subsequently selected as a function, at least in part, of a previously selected discrete element of a potential destination address, such that selected discrete address elements cannot be combined to thereby yield a nonexistent potential destination location.
