On the other hand, an arrow or finger graphic for pointing a specific object or selecting a menu in the display unit 151 is referred to as a pointer or a cursor. However, in the case of a pointer, it often means a finger or a stylus pen for a touch operation or the like. Therefore, in the present specification, the graphic displayed on the display unit 151 is referred to as a cursor to clearly distinguish the two, and a physical means capable of performing touch, proximity touch, and gesture such as a finger or a stylus pen is referred to as a pointer. It is called.

3 is a front view of an embodiment of a vehicle-mounted terminal to which the present invention is applied.

As shown in FIG. 3, the vehicle-mounted terminal to which the present invention is applied is embedded in a vehicle, as well as a fixed vehicle-mounted terminal that provides a navigation screen and a multimedia playback screen, and separately attached to the vehicle to provide a navigation screen and a multimedia playback screen. It includes a fixed vehicle mounting terminal to provide.

Such a vehicle-mounted terminal also includes a touch screen to provide various interfaces according to a touch method, and provides all functions of the mobile terminal.

Hereinafter, the touch input processing apparatus according to the present invention provides a touch user interface in which various functions are performed through different touch input patterns. More specifically, when a specific function is being performed, the touch input processing apparatus recognizes a case where a single touch input is detected through a touch screen and when a multi-touch input is detected, recognizes a different command and recognizes the corresponding touch input. It is possible to perform the operation according to.

As an example of operations according to different touch inputs, a form in which the touch user interface according to the present embodiment is applied to scrolling of a menu composed of a plurality of pages will be described with reference to FIGS. 4 to 6.

4 shows an example of a play list structure composed of a plurality of pages in a music reproduction application.

Referring to FIG. 4, the play list 300 includes 13 pages 301 to 313 in total, and each page is disposed adjacent to each other in the horizontal direction. For example, one page 301 is located on the left side of the two pages 302, and three pages 303 are located on the right side. At this time, it is assumed that bookmarks are set on pages 1 and 12, and one page corresponds to the full screen size of the touch screen 151.

In the menu configuration as illustrated in FIG. 4, page switching according to a general touch input will be described with reference to FIG. 5.

5 illustrates an example in which a page is scrolled according to a single touch input in the touch input processing apparatus according to the present invention.

First, when two pages 302 are displayed on the touch screen as shown in (a) of FIG. 5, the user is located at the top of the page in order to change the currently displayed page to the next page (ie, three pages). The page move button 420 may be selected as a touch input through the pointer 430. Accordingly, as shown in FIG. 5C, three pages 303 are displayed on the touch screen.

Instead of touching the move button, as shown in (b) of FIG. 5, the pointer 430 having one touch point (in this case, the user's finger) is dragged to the left in contact with a point on a page displayed on the touch screen. As a method of releasing the contact state, three pages 303 may be displayed as shown in FIG. 5C.

Hereinafter, for convenience, a touch input for releasing the contact state after moving in one direction while the pointer is in contact with the touch screen is referred to as a “flicking touch”.

Of course, when moving to the previous page, the user may select the previous page move button 410 or apply a flicking touch input in the right direction.

Since the page moving method described above with reference to FIG. 5 is scrolled by one page with one touch input, in order to move to a specific page, for example, a favorite page, the current page and the page on which the bookmark is set are touched apart. There is an inconvenience of having to perform the input. In order to solve this problem, in the present embodiment, when the flicking input through the multi-touch is applied in an arbitrary direction, the favorite page closest to the corresponding direction may be immediately displayed. This will be described with reference to FIG.

6 illustrates an example in which a page is scrolled according to a multi-touch input in the touch input processing apparatus according to the present invention.

In FIG. 6, it is assumed that a menu configuration as shown in FIG. 4 is applied.

First, in a state in which two pages 302 are displayed as shown in FIG. 6A, the user flicks left or bottom with multi-touch using two or more pointers (here, two fingers 510 and 520). Touch input can be applied.

Accordingly, as shown in (b) of FIG. 6, page 12 (312), which is a favorite page set on the right side of page 2 (302), is displayed. At this time, when the flicking touch input is applied in the right direction or the upper direction again by multi-touch as shown in (c) of FIG. 6, the favorite-set page located on the left side of the page 1212 312 as shown in FIG. 1 page 301 may be displayed.

Hereinafter, a method of setting a bookmark page that can be directly moved through multi-touch will be described with reference to FIG. 7.

First, referring to FIG. 7A, a bookmark may be set on at least some of a plurality of pages provided by a corresponding application according to a predetermined command input through the user input unit 130 and / or the touch screen 151. A menu screen may be displayed. The user may select a box corresponding to a page for which a bookmark is to be set to make a check state, or select a box that has already been checked to release the bookmark setting.

Meanwhile, when a multi-touch input is detected, instead of moving to a page where a parameter is set in advance, a predetermined number of pages may be scrolled. For example, if the preset number of pages is 5, the pages are scrolled to correspond to the flicking direction by one page in general flicking, but when the multi-touch flicking is input, the pages are scrolled to correspond to the flicking direction by five pages. It may be scrolled. In detail, if multi-touch flicking is input from page 1 to left, page 6 may be immediately displayed. When the multi-touch input corresponds to the above operation, the setting menu for setting the scroll unit may be configured as shown in FIG. 7B.

Referring to FIG. 7B, the user may select one of the check boxes corresponding to the number of pages 2, 5, and 10 prepared in advance, or set a desired number through manual input. Manual input may be performed through the virtual keypad 151b of FIG. 2 or the like.

Meanwhile, according to another exemplary embodiment of the present invention, a separate function may be performed instead of changing the performance unit / degree of the same function according to different types of touch inputs. This will be described with reference to FIG. 8.

8 illustrates an example in which different functions are performed according to different touch inputs in the touch input processing apparatus according to the present invention.

First, referring to FIG. 8A, a route guidance function is executed on the touch screen 151 of the mobile terminal to display a map of the vicinity and a current location 701 thereof. At this time, when the user inputs the flicking touch to the right through the pointer 710 having one contact point, the map may scroll to the right as shown in FIG. Of course, when the flicking touch is input to the left, the map will scroll to the left, and the map to which the flicking touch is input downward will be scrolled downward.

In contrast, when the user inputs multi-touch flicking in the right direction by simultaneously using the two pointers 710 and 720 as shown in FIG. 8C, the magnification of the map may be reduced as shown in FIG. 8D. have. Conversely, if multi-touch flicking is input in the left direction, the magnification of the map may be enlarged.

The page configuration shown in FIGS. 4 to 8, the number of pages, the type of application / list, the direction of the drag touch, and the setting screen are exemplary, and the present invention is not limited thereto. It may be applied to the flicking touch input of the vertical direction or the diagonal direction).

On the other hand, it is assumed that all the above-described touch input is input in a straight line toward one direction. By the way, when the mobile terminal is implemented in the form of a vehicle navigation, it is generally operated by the driver, it is generally disposed in the center of the vehicle rather than the front of the seat. Therefore, when the user performs a touch operation, it is not easy to apply a touch input in the horizontal or vertical direction of the touch screen precisely in the structure of the human body. In order to solve this problem, another embodiment of the present invention proposes to learn a user's touch pattern and apply it to the recognition of the user's touch input. This will be described with reference to FIG. 8.

9 illustrates an example of a touch pattern learning and recognition correction process in the touch input processing device according to the present invention.

When the driver's seat is located on the left side of the vehicle and the navigation device is located in the center of the vehicle, the navigation device is located on the right side of the driver relatively. In this case, even if the touch input is applied in parallel according to the structure of the human body or the user's habit, the trajectory of the touch through the actual pointer 800 becomes similar to that of FIG. 9A. In addition, the vertical touch input also has a form similar to that of FIG. 9B.

Accordingly, the controller 180 may receive a touch input in a horizontal / vertical direction through a predetermined setting menu in advance or store and average the touch pattern of the user cumulatively while performing a general operation. The touch pattern information of the user as shown in c) may be generated. Thereafter, when the touch input is detected on the touch screen, the controller 180 may recognize the command intended by the user more accurately than the stored touch pattern even though the touch input is not exactly horizontal or vertical.

10 is a flowchart illustrating a touch input processing method according to the present invention.

First, the touch detector detects a user's single flickering touch and multi-flicking touch on the touch screen (901).

Thereafter, the controller determines the type of touch (902).

As a result of the determination 902, if the single flicking touch input is performed, the function processor controls the function processor to perform a first function corresponding to the single flicking touch in the application (903).

As a result of the determination 902, if the multi-flicking touch input is performed, the function processor controls the function processor to perform a second function corresponding to the multi-flicking touch in the application (904).

Meanwhile, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily deduced by a computer programmer in the field. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention. The recording medium may include any type of computer readable recording medium.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
