Then, the grip sensor can recognize the touch input of the user of the first part 232 and the second part, and can sense the recognized position of the touch input. Accordingly, the control unit 180 can determine the type of the touch input of the user holding the body 230 of the stylus pen 200.

The stylus pen 200 may include a short range communication module (not shown) for transmitting a signal to the mobile terminal 100. The wireless communication module includes a button pressing signal generated by the button 220, a sensor for sensing a pressure applied to the pen tip 210, and a signal or a slope generated by a sensor for sensing a current flowing through the conductive material of the pen tip 210. [ And transmits the digital data generated by the detection sensor to the mobile terminal 100.

The transmitted signal may be received by the wireless communication unit 110 of the mobile terminal 100. Since the signal transmission to the mobile terminal 100 of the stylus pen 200 is generally performed while the mobile terminal 100 is in use, the distance between the mobile terminal 100 and the stylus pen 200 is not far away, ) Can be used.

Next, a method of controlling the mobile terminal 100 using the stylus pen 200 will be described with reference to FIG.

4 is a flowchart of a method of controlling a mobile terminal 100 according to an embodiment of the present invention. As shown in the figure, the controller 180 recognizes the touch input of the stylus pen 200 (S410). The control unit 180 can recognize a touch input by the body 230 of the stylus pen 200 recognized on the touch screen 151. [

For example, when the body 230 of the stylus pen 200 is formed as a cylinder, the body 230 of the stylus pen 200 may be touched to the touch screen 151 in a line shape.

Next, the short-range communication unit 114 receives the tilt signal of the stylus pen 200 from the stylus pen 200 (S420). The tilt signal may include a value for the tilt of the stylus pen 200 sensed by the tilt sensor of the stylus pen 200.

Then, the controller 180 determines the shape of the area touched on the touch screen 151 and the tilt of the stylus pen 200 from the tilt signal (S430).

First, the control unit 180 can determine the type of the area touched by the touch screen 151. [ For example, when one point of the touch screen 151 is touched by the pen tip 210 of the stylus pen 200, the controller 180 can determine the shape of the touched area as a point. When the touch screen 151 is touched by the body 230 of the stylus pen 200, the controller 180 may determine the shape of the touched area as a line.

The control unit 180 can determine the slope of the touch region determined as a line. Also, the controller 180 may determine whether the inclination of the stylus pen 200 is within a predetermined inclination range through the inclination of the stylus pen 200 sensed by the inclination sensor.

Accordingly, the controller 180 compares the tilt of the stylus pen 200 with the inclination of the touch area determined by the tilt sensor and compares the inclination of the touch area determined by the line with a touch of the stylus pen 200 .

For example, the controller 180 can determine the inclination of the stylus pen 200 in the area direction of the touch screen 151. In addition, when the stylus pen 200 is inclined on the touch screen 151, the controller 180 can determine the inclination of the stylus pen 200 on the same plane as the touch screen 151.

The controller 180 performs a predetermined function according to the determined shape and slope of the touch area (S440). For example, when it is determined that the shape of the area touched on the touch screen 151 is a line inclined to a predetermined tilt range, the controller 180 may display a plurality of objects for performing a predetermined function corresponding to the touched area have.

When the screen displayed on the touch screen 151 is aligned in the a-axis direction, if the touch input of the stylus pen 200 is determined to be inclined within 5 degrees from the b-axis, the control unit 180 displays a plurality of objects .

Next, a method of performing a predetermined function of the mobile terminal 100 using the stylus pen 200 will be described with reference to FIGS. 5 to 7. FIG.

As another example, the control unit 180 may display a new memo add object, a memo file open object, and a current memo save object in the index area 510 displayed when the memo contact application program is being executed.

That is, when the touch input by the stylus pen 200 is recognized and the shape of the area touched on the touch screen 151 is determined to be a line inclined within a predetermined tilt range, the controller 180 controls the touch screen 151 It is possible to display the index area 510 in which different combinations of objects are set according to the displayed screen or the application program to be executed.

In addition, each object may be represented as an object of the same type in the index area 510. The order of the objects displayed in the index area 510 may be changed and displayed according to the frequency with which the objects displayed in the index area 510 are selected.

Next, as shown in Fig. 5C, when the touch input to the object 512 for executing the memo application is recognized, the control unit 180 can execute the memo application and display the execution screen .

Alternatively, when the touch input to the object 518 for setting the object to be displayed in the index area 510 is recognized, the controller 180 may display a list of application programs that can be displayed in the index area 510. The list of application programs can be displayed as a list of objects corresponding to each application program.

For example, when the user touches one of the displayed application programs, the controller 180 may display the object corresponding to the selected application program in the index area 510.

Alternatively, if one of the selected application programs is touched and dragged to an object displayed in the index area 510, the control unit 180 displays the object corresponding to the touched application program as an object displayed in the index area 510 Can be replaced and displayed.

Alternatively, when the user touches an object displayed in the index area 510 and drags it out of the index area 510, the controller 180 can delete the object touched in the index area 510 and display the deleted object.

As another example, as shown in Fig. 5 (d), the control unit 180 may display a list of application programs in the plurality of arrays 530, respectively.

An object selection area 534 for placing an application program to be displayed in the index area 510 and an object for inserting an object corresponding to the application program located in the object selection area into the index area 510 are arranged at the lower end of each array 530, (536) may be displayed.

The application programs displayed in each array 530 can be moved up and down in the array 530 and can be located in the object selection area through up and down movement.

When the stylus pen 200 is moved so that the object displayed in the index area 510 and the array 530 are positioned on the same line and the object insertion object 536 is touched, An object of the application program located in the object selection area 534 of the array 530 in which the array 530 is located can be replaced with the object displayed in the index area 510 and displayed.

5D, a contact object is displayed in the object selection area 534a of the first array 530a and a Bluetooth object is displayed in the object selection area 534b of the second array 530b. The activated object may be displayed, and the brightness setting object may be displayed in the object selection area 534c of the third array 530c.

At this time, the user places the stylus pen 200 at the bottom of the objects 536a, 536b, and 536c inserted in the index area 510, and when the object is selected, the control unit 180 displays the message application program 514, , An object for executing the subway application program 516 and an object 518 for setting an object to be displayed in the index area 510 can be changed into a contact object, a Bluetooth enabled object, and a brightness setting object, respectively.

6 is an exemplary diagram illustrating a mobile terminal 100 according to another exemplary embodiment of the present invention performing a predetermined function according to a touch input using the stylus pen 200. Referring to FIG. As shown in FIG. 6A, the controller 180 may display the object 600 on the touch screen 151. It is assumed that the object 600 is due to drawing input through the stylus pen 200.

In addition, the body 230 of the stylus pen 200 can be touched in the form of a line on the left side of the touch screen 151. The control unit 180 can determine the slope of the touch region determined as a line. Also, the controller 180 may determine whether the inclination of the stylus pen 200 is within a predetermined inclination range through the inclination of the stylus pen 200 sensed by the inclination sensor.

Accordingly, the controller 180 compares the tilt of the stylus pen 200 with the inclination of the touch area determined by the tilt sensor and compares the inclination of the touch area determined by the line with a touch of the stylus pen 200 .

6 (b), if the touch input of the stylus pen 200 is determined to be a gradient within 5 degrees from the a-axis and is dragged to the right side of the touch screen 151 while maintaining the inclination, The control unit 180 can delete the object 600 displayed on the locus touched by the stylus pen 200. [

6 (c), when the object is displayed on the touch screen 151 and the tilt of the touched area is changed while the stylus pen 200 is touched, The visual effect of the object 600 displayed on the locus touched by the pen 200 can be changed.

6 (d), when the body 230 of the stylus pen 200 is tilted from the a axis to the inclination of the c axis in a touched state, the controller 180 controls the stylus pen 200 The brightness of the object 600 displayed on the locus touched by the user can be reduced to a predetermined level.

When the stylus pen 200 is tilted at a slope of c from the a axis in a state where the body 230 of the stylus pen 200 is touched, the control unit 180 controls the stylus pen 200 by the stylus pen 200 The brightness of the object 600 displayed on the touched trajectory can be reduced to a predetermined level.

That is, the controller 180 can perform a predetermined function according to a change in the tilt of the touched area when the body 230 of the stylus pen 200 is touched.

FIG. 7 is an exemplary diagram illustrating a mobile terminal 100 according to another embodiment of the present invention performing a predetermined function according to a touch input using the stylus pen 200. Referring to FIG. As shown in FIG. 7 (a), the control unit 180 can display the object 700 on the touch screen 151. It is assumed that the object 700 is due to drawing input through the stylus pen 200.

7 (b), the body 230 of the stylus pen 200 can be touched to the touch screen 151 in the form of a line. The control unit 180 may determine the shape of the area touched by the touch screen 151 as a line.

The control unit 180 can determine the slope of the touch region determined as a line. Also, the controller 180 may determine whether the inclination of the stylus pen 200 is within a predetermined inclination range through the inclination of the stylus pen 200 sensed by the inclination sensor.

Accordingly, the controller 180 compares the tilt of the stylus pen 200 with the inclination of the touch area determined by the tilt sensor and compares the inclination of the touch area determined by the line with a touch of the stylus pen 200 .

At this time, if the area touched by the stylus pen 200 is determined as a line, the controller 180 may divide the object 700 displayed in the area where the line is positioned with respect to the line.

The control unit 180 may divide the object 700 such that the slope of the reference line dividing the object 700 is equal to the slope of the area touched by the stylus pen 200. [

In addition, the controller 180 may display the divided objects 700a and 700b at a distance 710 corresponding to the width of the area to be touched.

7 (c), when the stylus pen 200 is moved up and down with the touch screen 151 being touched, the controller 180 moves the stylus pen 200 up and down It is possible to display two objects 700a and 700b separated by one distance apart.

Next, with reference to FIG. 8, a method of changing the shape of the object displayed on the touch screen 151 according to the position where the stylus pen 200 is held will be described.

First, when the control unit 180 recognizes the touch trajectory by the stylus pen 200, it can display an object corresponding to the touch trajectory. The control unit 180 can display the touch trajectory according to the drawing mode when the touch trajectory is recognized. At this time, the touch input by the stylus pen 200 includes a touch input by the pen tip 210 of the stylus pen 200.

For example, when the control unit 180 is in the pen mode, the recognized touch trajectory can be displayed as a trajectory drawn by the pen. As another example, when the brush mode is selected, the control unit 180 displays the recognized touch trajectory in a trajectory drawn by the brush, and in the charcoal mode, displays the recognized touch trajectory in a trajectory drawn by charcoal.

As another example, the controller 180 may display a pointer on the touch screen 151 according to the recognized touch input when the pointer mode is selected.

FIG. 8 is an exemplary diagram for changing the visual effect of an object displayed according to a position where the mobile terminal 100 grasps the stylus pen 200 according to an embodiment of the present invention.

The user can hold the body 230 of the stylus pen 200 in various forms by hand. Then, the grip sensor senses the position where the stylus pen 200 is held, and accordingly, the controller 180 can change the visual effect of the object by the touch input of the stylus pen 200.

For example, as shown in Fig. 8 (a), when the first part 232 is detected, stopped, and restrained with the thumb as if holding a general pen, and the second part 234 is held with the palm of the hand, A touch may be input to three areas of the first part 232 and a touch may be input to one area of the second part 234. [

Then, the controller 180 recognizes the touch input sensed by the grip sensor and can change the drawing mode to the pen mode. When the mode is changed to the pen mode, the control unit 180 displays the locus touched by the stylus pen as a trail 810 drawn with a pen, and displays an indicator 812 indicating the current pen mode on the touch screen 151 .

8 (b), when the touch input is detected in five areas of the body 230 of the stylus pen 200, the controller 180 recognizes the touch input sensed by the grip sensor, You can change the drawing mode to the brush mode.

When the control unit 180 changes to the brush mode, the locus touched by the stylus pen is displayed as a trace 820 drawn by the brush, and an indicator 822 indicating that the brush mode is currently displayed is displayed on the touch screen 151 Can

8 (c), when the touch input is detected only in the first portion 232, the controller 180 recognizes the touch input sensed by the grip sensor and can change the drawing mode to the charcoal mode have.

When the control unit 180 changes to the charcoal mode, the locus touched by the stylus pen is displayed as a locus 830 drawn in charcoal, and an indicator 832 indicating that the charcoal mode is currently displayed is displayed on the touch screen 151 Can

8 (d), when the touch input is sensed only in the second portion 234, the controller 180 recognizes the touch input sensed by the grip sensor and sets the drawing mode to the pointer mode Can be changed.

When the controller 180 is changed to the pointer mode, the control unit 180 may display a point to be touched by the stylus pen with a pointer 840 and display an indicator 842 on the touch screen 151 indicating that the pointer mode is the current pointer mode

Accordingly, the mobile terminal 100 can display the object to be displayed on the touch screen 151 differently according to the touch input, according to the shape in which the stylus pen 200 is held.

9, the visual effect of the object displayed on the touch screen 151 by the touch input of the pen tip 210 of the stylus pen 200 can be detected by touching the touch screen 151 with the pen tip 210. [ The following describes how to change stepwise according to time.

9 is a diagram illustrating an example in which the visual effect of an object displayed corresponding to a touch input is changed according to a time when the mobile terminal 100 is touched by the stylus pen 200 according to an embodiment of the present invention. 9A, the controller 180 may display the object 900a corresponding to the trajectory touched by the stylus pen 200 on the touch screen 151. In this case,

The control unit 180 can change the visual effect of the object 900a corresponding to the touched trajectory when the time touched by the stylus pen 200 increases.

9B, the thickness of the locus 900b of the touch input displayed on the touch screen 151 according to the time that the stylus pen 200 is touched on the touch screen 151 It can be thickened. The control unit 180 can display the thickness of the locus 900a by 0.5 mm when the stylus pen 200 is first touched to the touch screen 151 to display the locus.

If the stylus pen 200 is touched by the touch screen 151 to display the trajectory corresponding to the first section, the controller 180 increases the thickness of the trajectory to 1 mm and displays the result 900b.

The control unit 180 may increase the thickness of the trajectory by 2 mm when the stylus pen 200 is touched by the touch screen 151 to display the trajectory in the second period. That is, the control unit 180 can gradually increase the thickness of the locus as the stylus pen 200 is touched on the touch screen 151 to display the locus.

However, the time when the stylus pen 200 is touched on the touch screen 151 to display the trajectory and the visual effect of the trajectory to be changed corresponding thereto are not limited to the thickness change.

Next, a method of releasing the visual effect of the object 900b according to the touch input to the visual effect canceling object displayed on the touch screen 151 will be described.

As shown in FIG. 9C, the controller 180 may display an object 910 for releasing the visual effect in one area of the touch screen 151. The control unit 180 can release the visual effect when the user touches the visual effect release object 910 with the stylus pen 200 or recognizes an input to drag two points on the object 910. [

In addition, the control unit 180 may increase the degree of visual effect cancellation according to the number of times or time that the visual effect cancellation object 910 is touched or dragged.

For example, when the stylus pen 200 is touched on the touch screen 151 and the thickness of the trajectory displayed is 2 mm, the control unit 180 sets the thickness of the trajectory to 1 mm , And the thickness of the trajectory can be reduced to 0.5 mm by inputting the visual effect release object twice by touch dragging.

9 (d), when the stylus pen 200 further includes an acceleration sensor, the acceleration sensor can sense the acceleration and the rotational direction of the stylus pen 200 when the stylus pen 200 is rotated . Then, the signal including the sensed acceleration and the direction of the rotational motion may be transmitted to the short range communication unit 114 of the mobile terminal 100.

The control unit 180 recognizes the gesture for rotating the stylus pen 200 and can gradually release the visual effect of the object 900b according to the number of rotations or the angle of the stylus pen 200. [

Next, with reference to FIG. 10, a method for changing a visual effect of an object through an input for pressing a button 220 provided on one side of the stylus pen 200 will be described.

10 is an exemplary diagram illustrating a mobile terminal 100 according to an exemplary embodiment of the present invention receiving a button pressing signal from the stylus pen 200 and performing a predetermined function according to a button pressing signal. As shown in FIG. 10 (a), the controller 180 can display the text 1000 on the touch screen 151.

At this time, the locus by the touch input can be displayed on the touch screen 151 as a highlighter. The controller 180 may display an indicator 1020 on the touch screen 151 indicating the highlight pen mode.

Then, the user can press the button 220 of the stylus pen 200 while being touched to the text portion for highlighting the pen tip 210 of the stylus pen 200. Then, the short-range communication unit 114 receives a button press signal of the stylus pen 200. [

Then, as shown in FIG. 10 (b), the control unit 180 can highlight the whole row 1002 of the touched text when the button press signal is received.

10 (c), the control unit 180 can display an execution screen of the memo application program. Text 1010 can be displayed in the memo application program.

At this time, the locus by the touch input can be displayed on the touch screen 151 with a pen. The controller 180 may display an indicator 1020 on the touch screen 151 indicating the pen mode.

Then, the user can press the button 220 of the stylus pen 200 with the pen tip 210 of the stylus pen 200 being touched on the execution screen of the memo application program. Then, the short-range communication unit 114 receives the button 220 signal of the stylus pen 200.

Then, as shown in FIG. 10 (d), the controller 180 can generate a new memo 1030 when the button press signal is signaled.

That is, the function performed when the button press signal is received may be set differently according to the screen displayed on the mobile terminal 100. Also, depending on the drawing mode, the function performed when the button press signal is received can be set differently.

Even in the same drawing mode, the function performed by the controller 180 when the button press signal is received can be changed according to the application program currently being displayed and executed.

Also, even when the same application program is being executed, the function performed by the control unit 180 when the button pressing signal is received according to the drawing mode can be changed.

A camera (not shown) is mounted on the stylus pen 200, and the camera recognizes light transmitted through a lens provided in the camera and converts the light into digital data. The camera may be integrated with the pen tip 210 located at one end of the stylus pen 200 or may be located at the other end opposite to the pen tip 210.

When the button 220 of the stylus pen 200 is pressed, the camera recognizes light transmitted through the lens. 3, the button 220 may be positioned on the side surface of the stylus pen 200. When the camera 220 is integrated with the pen tip 210, the button 220 may be positioned on the side of the stylus pen 200, The button 220 can be pushed in such a manner that the other end is pressed.

The stylus pen 200 may include a wireless communication module that transmits a signal to the mobile terminal 100. The wireless communication module transmits the image photographed by the camera to the mobile terminal 100. The transmitted color information may be received by the wireless communication unit 110 of the mobile terminal 100. Since the image captured by the camera of the stylus pen 200 is transmitted to the mobile terminal 100 during the use of the mobile terminal 100 in general, the distance between the mobile terminal 100 and the stylus pen 200 is not distant The short range communication module 114 can be used.

Hereinafter, a method of photographing an image with the stylus pen 200 and using the stylus pen 200 on the touch screen 151 of the mobile terminal 100 will be described with reference to FIGS. 11 to 12. FIG. Figs. 11 to 12 are views illustrating screens of the touch screen 151 for outputting and using photographed images of the stylus pen 200 according to an embodiment of the present invention.

As shown in Fig. 11 (a), the user can press the button 220 and approach the camera of the stylus pen 200 to the surrounding object 1110 (in the drawing, the fabric). The pen tip 210 of the stylus pen 200 is positioned adjacent to the fabric 1110 in proximity to the fabric 1110. The pen tip 210 of the stylus pen 200, Can be photographed and converted into digital information.

The image is transmitted to the mobile terminal 100 through the wireless communication module of the stylus pen 200 and the wireless communication unit 110 of the mobile terminal 100 and is output to the touch screen 151 through the pop- .

An image palette 1104 may be provided so as to insert the photographed image 1106 in the closed curve area displayed on the touch screen 151 by photographing the fabric 1110 while the drawing function or the memo function is executed. A photographed image 1106 may be added to the palette 1104.

The operation to be added to the pallet 1104 may be set to be automatically performed after a predetermined time, or may be added by moving a popup window displaying a color to the pallet 1104.

The control unit 180 may insert the photographed image 1106 added to the pallet 1104 into the pattern image 1108 in the closed curve area 1102 displayed in the touch screen 151 as shown in FIG. In particular, when a picture is drawn, a pattern of objects in the vicinity can be directly used on the screen of the touch screen 151, so that various pattern images can be utilized.

12 (a), when the pattern image 1200 is drawn on the touch screen 151 by the user, the pattern image displayed on the touch screen 151 is photographed by the camera, and the control unit 180 May add the photographed pattern image to the pallet 1202. [ Alternatively, the pattern image 1204 may be added to the palette 1202 via an input that touches the pattern image 1200 displayed on the touch screen 151.

12 (b), the pattern image 1204 added in Fig. 12 (a) can be inserted into the closed curve area 1210 displayed on the touch screen 151 by the user.

Next, with reference to FIG. 13, a method of turning off the backlight unit of the touch screen 151 or reducing the light amount according to the position where the stylus pen 200 contacts the mobile terminal 100 will be described.

FIG. 13 is an exemplary diagram for stopping the driving of the backlight unit of the touch screen 151 of the mobile terminal 100 using the stylus pen 200 according to an embodiment of the present invention. The body 230 of the stylus pen 200 may contact the touch screen 151 to terminate the driving of the backlight unit of the touch screen 151 as shown in FIG.

For example, when the user uses the mobile terminal 100 with the stylus pen 200, when the stylus pen 200 is placed on the touch screen 151, the controller 180 controls the touch input of the stylus pen 200 The driving of the backlight unit can be terminated. At this time, the control unit 180 can reduce the light amount of the backlight unit step by step as time elapses after the user places the stylus pen 200 on the touch screen 151. When the predetermined time has elapsed, The controller 180 can terminate the driving of the backlight unit.

Thereafter, when the stylus pen 200 is separated from the touch screen 151, the control unit 180 can drive the backlight unit again.

13 (b), when the stylus pen 200 further includes a magnetic substance, the stylus pen 200 may include a magnetic body and a sensor for sensing magnetism on one side of the mobile terminal 100, And may be constrained to a side surface of the mobile terminal 100 by a magnetic force. The mobile terminal 100 can sense the magnetism of the magnetic body of the stylus pen 200 and terminate the driving of the backlight unit.

Thereafter, when the stylus pen 200 is separated from the mobile terminal 100 and is no longer able to sense the magnetism, the controller 180 can drive the backlight unit again.

In addition, the control unit 180 can change the mobile terminal 100 to the lock mode upon termination of driving the backlight unit.

Meanwhile, the pen tip 210 of the stylus pen 200 may include a photoelectric element. The control unit 180 can emit the photoelectric element with the color of the object displayed corresponding to the locus of the touch input. At this time, the photoelectric device may be integrated with the pen tip 210.

For example, when the trajectory of the touch input input by the user is displayed in red, the control unit 180 transmits a signal for causing the photoelectric element of the stylus pen 200 to emit red light to the local communication unit 114 via the stylus pen 200 ). In this case, the photoelectric elements provided on the pen tip 210 of the stylus pen 200 emit red light and can emit light with the same color as the trajectory of the touch input.

As another example, when the thickness of the trajectory of the touch input input by the user is 0.5 mm, the controller 180 emits the blue color of the photoelectric element and emits the green color of the photoelectric element in the case of 1 mm.
