Navigation system and control method thereof
First Claim
Patent Images
1. A navigation system, comprising:
- a controller;
a touch screen coupled to the controller, for receiving a touch input and displaying a navigation map in a first mode;
a memory device coupled to the controller, for storing a database containing a user reconfigurable set of symbols; and
mode-switching mechanism for issuing a mode-switching command to selectively switch the navigation system from the first mode into a second mode defining a handwriting input mode;
wherein the controller acquires input information by recognizing a handwriting input conducted on the touch screen corresponding with at least one of said reconfigurable set of symbols in the handwriting input mode, and searches the database responsive to a selective input symbol handwritten on said touch screen for a facility information corresponding to the input information, and displays facilities represented by the facility information in the navigation map in the first mode.

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.

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 from a first mode into a second mode defining 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 containing a user reconfigurable set of symbols for a facility information corresponding with at least one of said reconfigurable set of symbols to the input information; and showing facilities represented by the facility information in a navigation map in the first mode. - View Dependent Claims (20, 21)

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 from a first mode into a second mode defining 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 containing a user reconfigurable set of symbols for a facility information corresponding with at least one of said reconfigurable set of symbols to the input information; and showing facilities represented by the facility information in the navigation map in the first mode. - View Dependent Claims (23, 24)
