Abstract

A navigation system and method for providing turn-by-turn instructions for guiding a user along a route. The navigation system includes a global positioning system (GPS) receiving module for determining position information of the navigation system, a display unit for displaying information to guide a user along a route, a storage unit for storing map information, and a controller for processing the position information and the map information in order to concurrently provide a next turn-by-turn instruction and one or more subsequent turn-by-turn instructions to the user via the display unit.

Claims

1. A navigation system comprising:

a global positioning system (GPS) receiving module for determining position information of the navigation system;

a display unit for displaying information to guide a user along a route;

a storage unit for storing map information; and

a controller for processing the position information and the map information in order to concurrently provide a next turn-by-turn instruction and one or more subsequent turn-by-turn instructions to the user via the display unit.

2. The navigation system of claim 1, wherein the next turn-by-turn instruction is displayed in a first window and the one or more subsequent turn-by-turn instructions are displayed in a second window in response to an input provided by the user.

3. The navigation system of claim 1, further comprising a wireless communication module for receiving traffic information, wherein the one or more subsequent turn-by-turn instructions are determined based on the traffic information.

4. The navigation system of claim 1, wherein the one or more subsequent turn-by-turn instructions are each associated with a corresponding detour command for determining a detour route avoiding the corresponding subsequent turn-by-turn instruction and for determining one or more subsequent detour turn-by-turn instructions based on the detour route.

5. The navigation system of claim 4, wherein the user initiates the detour command, and wherein the controller determines the detour route and the one or more subsequent detour turn-by-turn instructions based on the detour route.

6. The navigation system of claim 5, wherein the controller replaces the route with the detour route.

7. The navigation system of claim 5, wherein the controller displays the one or more subsequent detour turn-by-turn instructions in a third window.

8. The navigation system of claim 5, wherein the detour command is initiated by a touch input from the user on the display.

9. The navigation system of claim 5, further comprising a voice recognition module, wherein the respective detour command is initiated via the voice recognition module.

10. The navigation system of claim 6, wherein the controller updates the one or more subsequent turn-by-turn instructions based on the detour route.

11. The navigation system of claim 1, wherein a number of the one or more subsequent turn-by-turn instructions is determined based on a magnification of the display or a distance of the route.

12. The navigation system of claim 1, wherein the next turn-by-turn instruction and the one or more subsequent turn-by-turn instructions each comprises a location and a proceeding direction.

13. A method for guiding a user along a route, the method comprising:

determining a current position of a user; and

concurrently providing the user with a next turn-by-turn instruction and one or more subsequent turn-by-turn instructions in list form.

14. The method of claim 13, wherein the next turn-by-turn instruction is displayed in a first window, and wherein the one or more subsequent turn-by-turn instructions are displayed in a second window in response to an input by the user.

15. The method of claim 13, wherein the one or more subsequent turn-by-turn instructions are each associated with a corresponding detour command for determining a detour route avoiding the corresponding subsequent turn-by-turn instruction.

16. The method of claim 13, further comprising:

detecting a detour command associated with at least one of the one or more subsequent turn-by-turn instructions;

determining a detour route avoiding the at least one of the subsequent turn-by-turn instructions; and

replacing the route with the detour route.

17. The method of claim 16, further comprising:

determining one or more subsequent detour turn-by-turn instructions; and

displaying the one or more subsequent detour turn-by-turn instructions.

18. The method of claim 13, wherein the next turn-by-turn instruction and the one or more subsequent turn-by-turn instructions each include a location and a proceeding direction.

19. The method of claim 16, wherein the detour command is detected via a touch input.

20. The method of claim 16, wherein the detour command is detected via a voice input.

21. The method of claim 16, wherein the number of the one or more subsequent turn-by-turn instructions is determined depending on a magnification of a display or a distance of the route.

22. A method for providing a next turn-by-turn instruction and one or more subsequent turn-by-turn instructions for guiding a user along a route, the method comprising:

detecting a turn-by-turn list command,

determining the next turn-by-turn instruction and the one or more subsequent turn-by-turn instructions for the route;

generating a turn-by-turn list using the one or more subsequent turn-by-turn instructions; and

displaying the next turn-by-turn instruction concurrently with the turn-by-turn list.

23. The method of claim 22, further comprising:

measuring an elapsed time after displaying the next turn-by-turn instruction and the turn-by-turn list;

determining whether the elapsed time is greater than a predetermined value; and

no longer displaying the turn-by-turn list if the elapsed time is greater than the predetermined value.

24. The method of claim 22, further comprising:

detecting a touch input; and

no longer displaying the turn-by-turn list upon detecting the touch input.

25. The method of claim 22, further comprising:

detecting a detour command associated with at least one of the one or more subsequent turn-by-turn instructions;

determining a detour route avoiding the at least one subsequent turn-by-turn instruction;

generating one or more subsequent detour turn-by-turn instructions; and

replacing the displayed one or more subsequent turn-by-turn instructions with the one or more subsequent detour turn-by-turn instructions.

26. The method of claim 25, further comprising.

measuring an elapsed time after displaying the next turn-by-turn instruction and the one or more subsequent detour turn-by-turn instructions;

determining whether the elapsed time is greater than a predetermined value; and

no longer displaying the one or more subsequent detour turn-by-turn instructions if the elapsed time is greater than the predetermined value.

27. The method of claims 25, further comprising:

detecting a touch input; and

no longer displaying the one or more subsequent detour turn-by-turn instructions upon detecting the touch input.
