Abstract

A navigation system includes a touch screen for receiving a touch input and displaying a navigation map, mode-switching means for issuing a mode-switching command to switch the navigation system into an input mode, a memory for storing a database, and a controller to recognize a handwriting input or a gesture input to acquire an input information, search the database for a facility information corresponding to the input information, and show facilities represented by the facility information in the navigation map.

Claims

1. A navigation system, comprising:

a controller;

a touch screen coupled to the controller, for receiving a touch input and displaying a navigation map;

a memory coupled to the controller, for storing a database; and

mode-switching means for issuing a mode-switching command to switch the navigation system into a handwriting input mode;

wherein the controller acquires an input information by recognizing a handwriting input conducted on the touch screen in the handwriting input mode, searches the database for a facility information corresponding to the input information, and shows facilities represented by the facility information in the navigation map.

2. The navigation system of claim 1, wherein the mode-switching means comprises a virtual graphical button displayed on the touch screen, for receiving a touch to issue the mode-switching command.

3. The navigation system of claim 1, wherein the mode-switching means comprises a gesture pre-defined to issue the mode-switching command.

4. The navigation system of claim 3, wherein the gesture comprises a multi-finger touch.

5. The navigation system of claim 1, wherein the controller compares the input information with a list to determine a category of the facilities corresponding to the input information.

6. The navigation system of claim 1, wherein the touch screen comprises a capacitive touch panel.

7. The navigation system of claim 1, wherein the touch screen comprises a resistive touch panel.

8. The navigation system of claim 1, wherein the touch screen comprises an ultrasonic touch panel.

9. The navigation system of claim 1, wherein the touch screen comprises an infrared touch panel.

10. A navigation system, comprising:

a controller;

a touch screen coupled to the controller, for receiving a touch input and displaying a navigation map;

a memory coupled to the controller, for storing a database; and

mode-switching means for issuing a mode-switching command to switch the navigation system into a gesture input mode;

wherein the controller acquires an input information by recognizing a gesture input conducted on the touch screen in the gesture input mode, searches the database for a facility information corresponding to the input information, and shows facilities represented by the facility information in the navigation map.

11. The navigation system of claim 10, wherein the mode-switching means comprises a virtual graphical button displayed on the touch screen, for receiving a touch to issue the mode-switching command.

12. The navigation system of claim 10, wherein the mode-switching means comprises a gesture pre-defined to issue the mode-switching command.

13. The navigation system of claim 12, wherein the gesture comprises a multi-finger touch.

14. The navigation system of claim 10, wherein the controller compares the input information with a list to determine a category of the facilities corresponding to the input information.

15. The navigation system of claim 10, wherein the touch screen comprises a capacitive touch panel.

16. The navigation system of claim 10, wherein the touch screen comprises a resistive touch panel.

17. The navigation system of claim 10, wherein the touch screen comprises an ultrasonic touch panel.

18. The navigation system of claim 10, wherein the touch screen comprises an infrared touch panel.

19. A control method for a navigation system including a touch screen for receiving a touch input and displaying a navigation map, the control method comprising the steps of:

responsive to a mode-switching command, switching the navigation system into a handwriting input mode;

in the handwriting input mode, recognizing a handwriting input conducted on the touch screen to acquire an input information;

searching a database for a facility information corresponding to the input information; and

showing facilities represented by the facility information in a navigation map.

20. The control method of claim 19, further comprising the step of comparing the input information with a list to determine a category of the facilities corresponding to the input information.

21. The control method of claim 19, further comprising the steps of:

indicating locations of the facilities in the navigation map; and

prompting related information of the facilities on the touch screen.

22. A control method for a navigation system including a touch screen for receiving a touch input and displaying a navigation map, the control method comprising the steps of:

responsive to a mode-switching command, switching the navigation system into a gesture input mode;

in the gesture input mode, recognizing a gesture input conducted on the touch screen to acquire an input information;

searching a database for a facility information corresponding to the input information; and

showing facilities represented by the facility information in the navigation map.

23. The control method of claim 22, further comprising the step of comparing the input information with a list to determine a category of the facilities corresponding to the input information.

24. The control method of claim 22, further comprising the steps of:

indicating locations of the facilities in the navigation map; and

prompting related information of the facilities on the touch screen.
