The present invention relates to a navigation system, and more particularly, a navigation system having a complex function that enables a user to easily input text through handwriting on a touch screen, set a destination, and rotate the map displayed on the touch screen at various angles. A system and a method of operating the same.

Navigation system (navigation system) is a system that accurately provides the destination information by providing the location information to the moving vehicle in operation. Global positioning system (GPS) using the position information received from the satellite to display the current position and direction of the moving object on the display screen of the navigation system, so if you enter the starting point and destination, the movement route and Displays estimated time required and distance. Therefore, when you visit the cobbled road, you arrive safely to your destination. The navigation system provides various functions such as real-time traffic information, living information, broadcast signal, and vehicle theft notification using wireless communication.

According to the conventional navigation system, when a destination is set by the user, the navigation system searches for the shortest path and the optimum distance to the destination, generates route information, and performs route guidance based on the route information. In this case, the user sets the destination using a keypad and a scroll displayed on a touch screen of the navigation system.

First, when setting a destination using scrolling on the touch screen 10, if a contact is maintained for a predetermined time, a scroll icon A is displayed on the touch screen 10 as shown in FIG. 1A. After that, if the contact is continued in the desired direction, scrolling is performed in the corresponding direction to move to the desired point. When a specific button, for example, a destination button is clicked on the moved point, the corresponding point is set as a destination. In this case, the map may be moved to a desired point by dragging without using scrolling. In the prior art as described above, the user needs to scroll and move to a desired point so that the user who does not have prior knowledge of the area has difficulty in setting a destination.

Next, when setting a destination using a keypad displayed on the touch screen 10, when the user selects a destination setting menu, a keypad as shown in FIG. 1B is displayed on the display screen of the touch screen 10. Then, the user touches the keys of the keypad one by one to input the destination name. In this case, the navigation system searches for a name matching the destination name in a memory (not shown) that stores search data such as a point of interest, an address, and a telephone number. For example, to set 'LG Electronics' as a destination, 'L' and 'G' buttons are sequentially selected on the keypad to input 'LG', and when the 'OK' button is selected, the navigation system selects the memory ( (Not shown), searches for names that match or include "LG." The navigation system selects one of the searched results and sets it as a destination. Then, if the destination set in this way is registered in the memory in the navigation system, when searching for the same destination, one of the pre-registered registration lists may be selected and set as the destination through the search menu as shown in FIG. 1C. This method is cumbersome to input one key of the keypad for each search.

On the other hand, the electronic map display method of the navigation system as described above, as shown in Figure 2a to rotate the map to display the center of the driver to display the map based on the north direction as shown in Figure 2b It is limited to choosing one of the north fixed manners. The user can click and set the compass icon set in the toggle form in one of two ways. In the case where the vehicle is fixed by the user, the map is rotated and displayed according to the driving progress of the vehicle in the state where the host vehicle position (driver's center) B is fixed. In addition, when it is set in the north-facing manner, a map is displayed based on the north direction, and the vehicle icon B is adjusted while being displayed while driving. In the prior art, there is a problem in that the map display method is fixed in two ways, so that the user cannot check the map in a desired direction and thus cannot satisfy the user's desire.

As described above, in the prior art, when the destination is set, it is troublesome to input the destination by touching the keys of the keypad one by one.

In addition, the map displayed on the touch screen is limited to selectively use one of the own vehicle fixing method and the north-type fixing method, and thus cannot be confirmed based on a desired direction, and thus cannot satisfy the user's desire.

Therefore, the present invention is to solve the problems of the prior art as described above, having a complex function that can easily set the destination through the character recognition (handwriting recognition) process by receiving a character written on the touch screen as an input An object of the present invention is to provide a navigation system and a method of operation thereof.

In the present embodiment, an example of setting a destination by receiving a character string written on a touch screen of the navigation system as a destination name will be described.

According to FIG. 3, the navigation system according to the present invention includes a touch screen 100 that receives text through a user's handwriting operation and displays an operation state and a result of the navigation system according to the input. The touch screen 100 also serves to receive a command signal for a general operation of the navigation system.

 The touch screen 100 is input by hand on the screen of the touch screen 100 when the text recognition function is turned on by the operation of the first hot key 102 and the first hot key 102 for the character recognition function on / off It includes a character input window 104 for receiving a character to be. Here, the character recognition function is a function for inputting a character by writing on the touch screen 100 using a user finger or a dedicated pen.

In addition, the touch screen 100 includes a second hot key 106 for turning on / off a rotating scroll function. The rotation scroll function is a function of rotating and displaying a map displayed on the touch screen 100 by a desired rotation amount using a rotation scroll.

Each time the first and second hot keys 102 and 106 of the touch screen 100 are pressed in a toggle form, an on / off state is alternately switched. Here, the first and second hot keys 102 and 106 are described as menu buttons displayed on the touch screen 100, for example, but the first and second hot keys 102 and 106 are the touch screen 100. ) May be provided as a separate button or switch.

The touch screen driver 110 is configured to control the input through the contact on the touch screen 100 and the operation state and the result according to the input. The touch screen driver 110 displays the text input through writing on the text input window 104 on the touch screen 100 as it is, and on the written text received from the text input window 104. The information about the transmission is transmitted to the character recognizer 130 through the control unit 160 to be described later.

In addition, the navigation system according to the present invention includes a character database 120 that stores character data including various character shapes for various characters. For example, the character database 120 stores data for various handwritten characters. A character recognition unit 130 is provided to analyze and recognize a character input through the touch screen with reference to the character data stored in the character database 120. For example, when a character string 'reverse sam' is input through the touch screen 100, the character recognition unit 130 cuts letters one by one ('reverse', 'three') and analyzes the corresponding letter, 'reverse sam'. Recognize it as a string.

In addition, the present invention is provided with a GPS module 140 for receiving location information from a GPS positioning satellite. In addition, an electronic map storage unit 150 for storing an electronic map represented by a numerical value is provided. The electronic map storage unit 150 includes search data such as a point of interest (POI), an address, and a phone number. Here, the search data is data provided to search for a name identical or similar to a character string input through the text input window 104 when setting a destination.

The controller 160 is configured to control the electronic map storage unit 150 to search for a name matching the character string input through the touch screen 100 and set it as a destination. In this case, the controller 160 searches for the name in the search data that matches the input string or includes the string. For example, a name such as 'Yeoksam Station', 'Yeoksam Tax Office', and 'Yeoksam Elementary School' is searched for as a name matching the string in the electronic map storage unit 150 by receiving a string of 'Yeoksam' as an input. When the searched name is one from the electronic map storage unit 150, the controller 160 receives the searched name from the user and sets the searched name as a destination. Alternatively, when there is a plurality of searched names, the controller 160 sets the selected name as a destination when one of them is selected by the user.

The controller 160 calculates a current location based on the location information received from the GPS module 140 and displays the matching location on the electronic map, thereby performing a general road guidance function that accurately leads to a destination. The controller 160 controls to rotate and display the electronic map by the rotation angle when the rotation angle is input through the rotation scroll on the touch screen 100 while the rotation scroll function is operated.

Hereinafter, the operation method of the navigation system with a complex function according to the present invention having the above configuration will be described in detail.

4 is a flowchart illustrating a step-by-step method of operating a navigation system with a complex function according to the present invention. In this embodiment, an operation method according to a destination setting of the navigation system will be described as an example.

If a destination setting menu is selected among various menus displayed on the touch screen 100, the controller 160 checks whether the text recognition function is on (S100). Herein, the controller 160 determines the text recognition function on / off state by checking a state flag value of the first hot key 102. For example, when the state flag value is '1', it is determined that the character recognition function is on, and when the state flag value is '0', it is determined that the character recognition function is off. The first hot key 102 operates in a toggle form, and the on / off state is alternately switched for each operation. If the character recognition function is turned on, the controller 160 displays a text input window 104 having a predetermined size on the touch screen 100 as shown in FIG. 5A.

In the text input window 104 on the touch screen 100, a text is input according to a user's writing operation (S110). In this case, the user may input text by writing in the text input window 104 using a finger or a dedicated pen. The touch screen driver 110 transmits the received text to the character recognition unit 130.

The character recognition unit 130 compares the information on the received character and the character data stored in the character database 120 to analyze the input character (S120). For example, as shown in FIG. 5A, when a name of a destination is written by a finger in the text input window 104, the touch screen driver 110 transmits the input text to the text recognition unit 130. The character recognition unit 130 receiving the input character recognizes the input character as 'LG' with reference to the character database 120. Here, the character recognition may be implemented by various character recognition methods such as a method using a histogram and a method of comparing the corresponding pixel values by dividing into several pixels.

The character recognition unit 130 transmits the recognized character string to the control unit 160. The controller 160 searches for a name matching the recognized character string among search data of the electronic map storage unit 150 and extracts a result matching the recognized character string. In this case, the controller 160 extracts a name (hereinafter, a matching result) that matches the string or includes the string. If there is only one extraction result matching result, the extracted matching result is displayed as shown in FIG. 5B and set as a destination through a confirmation procedure from the user (S132 and S140). In this case, in order to set the matching result as a destination, if the matching result, that is, 'LG electronic' is selected, the destination is set, and when the 'cancel' button is clicked, the character is input again through the touch screen 100. You can search again.

On the other hand, if there are a plurality of matching results extracted in operation 130, the controller 160 displays the extracted matching result list on the touch screen 100 as shown in FIG. 5C (S132 ′). When the user selects one of the matching result lists displayed on the touch screen 100, the controller 160 sets the matching result as a destination. For example, when 'LG electronic' is selected by the user in FIG. 5C, the controller 160 sets the 'LG electronic' as a destination.

When the destination setting is completed, the controller 160 calculates a current location based on the location information provided from the GPS module 140 and generates route information from the calculated current location to the set destination. In addition, the controller 160 starts the road guide based on the generated route information.

Next, a method of rotating the map through the rotating scroll of the navigation system according to the present invention will be described with reference to FIGS. 6 and 7.

6, when the second hot key 106 is operated by the user during the general road guide operation, the controller 160 checks the state flag for the second hot key 106 to turn on the scroll scroll function. Determine (S200). The second hotkey 106 operates in the same toggle format as the first hotkey 104.

The controller 160 waits until there is contact on the touch screen 100 when the rotation scroll function is turned on. In addition, when a touch occurs on the touch screen 100, the controller 160 checks whether the touch continues for a predetermined time (S210). As a result of the check, if the contact is maintained for a predetermined time, the controller 160 displays the rotating scroll icon D as shown in FIG. 7 on the touch screen 100 (S220). Here, the predetermined time is a criterion for recognizing an input signal input through the touch screen 100 as a rotation scroll command.

After the rotation scroll icon D is displayed on the touch screen 100, when the user draws a curve in a desired rotation direction, the controller 160 rotates the map along the drawn curve (S230 and S240). Alternatively, if the rotation command is not input in operation 230, the rotation scroll icon D disappears from the touch screen 100 after a predetermined time elapses.

If the contact on the touch screen 100 is stopped after rotating by a desired amount of rotation, the rotation operation of the map stops and after a predetermined time, the rotation scroll icon D disappears from the touch screen 100.

In operation 210, if the contact is not maintained on the touch screen 100 for a predetermined time, a basic scroll operation is performed. When the user scrolls in the desired direction, the controller 160 moves the map to the scrolled corresponding point.

In the above-described embodiment, the rotation of the map is rotated by a desired amount of rotation using an example of rotation. However, by applying the character recognition function described above, the rotation angle is received on the touch screen 100 as the rotation angle. The map can be rotated.

As described above, in the present invention, the destination name is directly written and input on the touch screen, so that the destination can be set quickly and conveniently, and the map can be rotated freely in a desired direction by using the rotation scroll.

The scope of the present invention is not limited to the above embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the navigation system and its operating method having a complex function according to the present invention as described in detail above, the following effects can be expected.

Characters can be entered quickly and conveniently by writing a destination name using a user's finger or a dedicated pen on the touch screen. In addition, since the input character is recognized and selected from the list of destinations searched through matching with the destination name previously stored in the navigation system, the destination can be easily set.

In addition, since a character can be input by writing a character on the touch screen surface, even a clumsy user can easily use the keypad and navigation system.

In addition, since it is possible to freely rotate the map by simply drawing a curve in a direction in which the user wants to rotate on the touch screen, it is possible to meet the needs of the user who wants to display the map in various ways.
