The present invention relates to a mobile communication terminal equipped with a control stick function and a method for performing the application thereof, and in particular, by using a main body as a control stick in a clamshell-type mobile communication terminal coupled by a two-axis hinge, it is possible to control an application including a game. The present invention relates to a mobile communication terminal and a method for executing an application with the mobile communication terminal.

In recent years, mobile communication terminals are supporting a miniaturization and high performance of components according to the development of technology, and thus, a variety of multimedia functions have been kept away from simple telephone calls.

These multimedia functions are especially well developed in terms of sound and graphics, which means that decoding digital sources such as mp3 format and output them through high-performance loudspeakers or decoding photo or video files and outputting them through high-resolution displays is possible. Yes.

On the other hand, with the development of the sound and graphics performance, it is possible to perform a variety of high-specific applications, in particular games, accompanied by technology to control the application more dynamically with a mobile communication terminal.

In particular, in order to escape the simplicity of the conventional basic operation method of operating an application by pressing a designated key button on the keypad, a representative interface is provided with a control stick in a mobile communication terminal to enable more dynamic and precise control. As shown in FIGS. 1 and 2, the rod-type control sticks 20 and 20 ′ are simply installed in the mobile communication terminal 10 to move the control sticks 20 and 20 ′ with respect to the mobile communication terminal 10. It was designed to operate applications such as games.

However, since the control stick must protrude vertically from the parent mobile terminal due to its characteristics, when the control stick is installed integrally with the mobile communication terminal, the mobile terminal becomes very difficult to carry, and is separated from the mobile communication terminal (FIG. 1). If folded (FIG. 2) to be stored or stored, the configuration becomes very complicated or a risk of loss occurs.

Therefore, in recent years, the product has been suggested to minimize the length of the control stick enough to hold the finger, but there is an example that did not have a sufficient effect in that the role can be played only if the length is large enough to hold the control stick.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to operate the main body as a control stick for a folder in a mobile communication terminal having a two-axis hinge, without affecting the original configuration of the mobile communication terminal. The present invention is to provide a mobile communication terminal that enables the operation of the game and the terminal, and another object of the present invention is to provide a method for performing an application to the mobile communication terminal.

A hot key is provided at the opposite end coupled to the biaxial hinge in the main body, and is preferably used as an input means when controlling the terminal by spatially rotating the main body in a state where the folder is fixed.

Another method according to the present invention for performing an application to the mobile communication terminal made as described above comprises the steps of: launching the application; Fixing the folder portion; While rotating the main body while looking at the display of the folder part, the sensor includes a process of controlling the application by recognizing the space rotated position.

When the sensor is a geomagnetic sensor, the method may further include setting the geomagnetism state detected by the geomagnetic sensor as a reference state after fixing the folder unit to the reference position.

In the process of controlling the application, the geomagnetic state detected at the position where the main body is rotated is compared with the reference state to calculate a change in azimuth to recognize the space rotated position of the main body.

Hereinafter, an embodiment of a mobile communication terminal equipped with a control stick function according to the present invention will be described in detail with reference to the accompanying drawings.

As illustrated in FIG. 3, the mobile communication terminal according to the present invention is implemented in a folder type mobile communication terminal 100 in which a folder unit 200 and a main body unit 300 are combined by a two-axis hinge 400.

The folder type mobile communication terminal 100 typically includes a folder unit 200 having a large display 210 on one side thereof, and a body unit 300 having a keypad 310 for inputting letters / numbers / menus. While being coupled by a hinge, the folder part 200 is normally stored and carried by folding the main body part 300, and while the folder part 200 is rotated and opened with respect to the main body part 300, the keypad 310 is viewed while viewing the display 210. ) To use the terminal function or make a phone call.

The biaxial hinge 400 combines the folder 200 and the main body 300 on two hinge axes orthogonal to each other so that the folder 200 and the main body 300 rotate in three dimensions in space. The surface on which the display 210 of the folder unit 200 is provided may be folded toward the main body 300 or may be folded to be exposed to the outside to output a video or the like through the display 210.

In this case, in particular, the two-axis hinge 400 applied to the mobile communication terminal 100 according to the present invention has a hinge axis in the state in which the folder part 200 and the main body part 300 are perpendicular to the display 210 of the folder part 200. The two hinges 410 and 420 which are parallel to each other and are orthogonal to each other are preferably formed.

This biaxial hinge is known in the art and there are various forms, the present embodiment has taken the hinge structure shown in Figure 3 as a representative example.

That is, referring to FIG. 4, the hinge axes of the first hinge 410 and the second hinge 420 that are orthogonal when an arbitrary rectangular coordinate axis is assumed in the plane occupied by the display 210 provided in the folder unit 200. By constructing the X and Y axes, the main body 300 can be rotated with respect to the folder part 200 in the Y and X axis directions, respectively. As a result, the main body 300 is rotated as will be described later. When in the reference position perpendicular to the folder portion 200, the main body portion 300 rotates freely in the front / rear, left / right and their combined directions by the biaxial hinge 400, and functions as a control stick. Will be performed.

In the folder type mobile communication terminal 100 coupled by the two-axis hinge 400, the folder 200 is rotated to be opened by an angle of 90 degrees with respect to the main body 300, and then the folder 200 And move the main body 300 back, front, left, and right while keeping it fixed at an arbitrary position, the sensor recognizes the movement of the main body 300 and sends information to a control unit (not shown) implemented by MSM (Mobile Station Modem). The main body unit 300 serves as a control stick by applying the control unit and controlling the mobile communication terminal 100 by reflecting this.

In this case, the sensor may be, for example, a geomagnetic sensor provided in the main body.

Referring to FIG. 5, the geomagnetic sensor 500 detects a terrestrial magnetic field of the earth so that the geomagnetic sensor 500 is positioned with respect to the earth magnetic field, that is, the horizontal angle of the geomagnetic sensor 500 with respect to the magnetic north. By continuously outputting data for (α) and vertical angle (β), it is possible to know the relative position change of the changed position from the reference position in comparison with the data for the horizontal angle and the vertical angle at any reference position. Magneto Resistive (MI), Magnet Inductive (MI), Flux Gate, etc. are available.

When the geomagnetic sensor 500 is provided in the main body 300, the position change is recognized as the main body 300 rotates in the directions of the front, rear, left and right with respect to the fixed folder 200, and the information is applied to the controller. This is to control the terminal according to the rotation of the main body 300.

At this time, the geomagnetic sensor 500 is provided at the end of the opposite side coupled to the biaxial hinge 400 in the main body 300, the largest position of the main body 300, the axis of the biaxial hinge 400 It is desirable to detect changes and allow more precise control.

As described above, a method of performing an application using the control stick function in the mobile communication terminal 100 equipped with the geomagnetic sensor 500 is as follows.

In this case, the application refers to all functions that are built in the mobile communication terminal and performed according to a user's needs, and in particular, a game function that requires control by the user is exemplified below.

First, the user enters a predetermined menu and launches a desired game.

The launched game may be controlled by manipulating the keypad 310 provided in the main body 300, but when selected to control using the control stick function according to the present invention, the main body 300 functions as a control stick by an initialization operation. Is required to input data for the horizontal and vertical angles at the reference position at which the relative position is to be determined.

Therefore, the folder unit 200 is fixed at an arbitrary position by placing the display unit 210 on the floor with the display 210 facing the user, and the main body unit 300 is a folder 200 as a reference position through a separate menu. By detecting and storing the geomagnetism in the vertical position, the game is ready for control.

Afterwards, when the game is executed, the geomagnetic sensor 500 recognizes the positional change of the main body 300 to control the game by simply rotating the main body 300 back and forth, right and left with respect to the fixed folder unit 200. It will be possible to play the game while looking at the display 210.

On the other hand, the launching of the game does not necessarily need to be performed before the initialization operation as described above, and the game may be launched after the initialization operation unless the position of the folder unit 200 is changed.

Another example of a sensor for detecting a movement of the main body may be a rotation detection sensor provided in the two-axis hinge.

The rotation sensor detects the degree of rotation of the two hinges 410 and 420 forming the two-axis hinge 400, respectively, and recognizes the degree of rotation of the main body 300 based on the folder part 200. Specifically, the main body 300 is the folder 200 by the hinge axes of the two hinges 410 and 420 constituting the X-axis and the Y-axis, respectively, in the plane occupied by the display 210 provided in the folder 200 as in the past. By detecting the degree of rotation in the Y-axis direction and the X-axis direction, respectively, and calculates the degree of rotation on the XY axis by the coordinates on the basis of the state that the main body 300 is perpendicular to the folder portion 200 It is to recognize the degree of rotation by the front / rear, left / right and a combination thereof for the folder unit 200 of the main body 300.

At this time, the individual rotation detection sensor for detecting the degree of rotation provided on each hinge also has a variety of known technologies, as a representative example of the resistance value according to the rotation of the folder as shown in Republic of Korea Utility Model No. 0357900 shown in FIG. Using this variable variable resistor 600, a technique for detecting the degree of rotation of the current value or the voltage value according to the change in the resistance value may be applied. In this case, the known technology may be applied to the two-axis hinge according to the present invention. Since the application is obvious to those skilled in the art, the description is omitted.

And the information recognized by the rotation detection sensor is applied to the control unit, the terminal is controlled in accordance with the rotation of the main body, such as when the geomagnetic sensor is installed.

On the other hand, the method of performing an application, especially a game, in a mobile communication terminal equipped with a rotation sensor and implementing a control stick function is basically the same as when an electric geomagnetic sensor is provided, but each time a geomagnetism is detected to detect a geomagnetism state. Instead of eliminating the process of setting the reference state, the degree of rotation of the biaxial hinge 400 in the state in which the main body 300 is perpendicular to the folder part 200 is referred to as the reference coordinate (0,0 on the XY axis). It should be set in advance to recognize it as).

Therefore, in order to play the game, the game is first launched, and the display 210 faces the user to fix the position by holding the folder 200 in his hand, and then the main body with respect to the folder 200. By rotating the unit 300, the game can be controlled by controlling the game.

On the other hand, in the mobile communication terminal equipped with a control stick function according to the present invention, one or a plurality of hotkeys 700 are provided at opposite ends coupled to the two-axis hinge 400 of the main body 300, and the main body 300 When the gripping by hand allows the user to comfortably press the hotkey 700 with the thumb, it can be used for input of a signal required for control like a shooting key of a joystick.

It is also possible to provide a hot key on any side of the folder unit 200, so that the user can input another signal by pressing the hot key while holding and supporting the folder unit by hand.

According to the mobile communication terminal with a control stick function according to the present invention as described above and an application execution method thereof, the control stick function can be implemented without affecting the appearance of the mobile communication terminal, thereby improving design and convenience at the same time. At the same time, there is a unique effect that allows a user to dynamically control an application such as a game.
