A screen control device according to an embodiment of the present invention includes a control unit 101 and a display unit 100. The display unit 100 receives the first input 11 and the second input 21, 22, 23, and 24. The first input 11 is input to an arbitrary point of the display unit 100 using a pointing means. The first input 11 may be made by touching the screen with a pointing means. The second inputs 21, 22, 23, and 24 are input at positions spaced apart from the first input 11. The second input 11 may be performed by touching the screen with a pointing device.

Hereinafter, a screen control method in an embodiment according to the present invention will be described. Screen control in one embodiment according to the present invention is performed on the second inputs 21, 22, 23, and 24 when the second inputs 21, 22, 23, and 24 are applied while the first input 11 is being applied. Accordingly, the control unit 101 controls the display unit 100, and when the application of the first input 11 ends, the control unit 101 ends control of the display unit 100. Alternatively, when application of the first input 11 ends after the application of the second inputs 21, 22, 23, and 24 ends, the control unit 101 ends control of the display unit 100.

Figure 1 shows the position where the second inputs 21, 22, 23, and 24 are input to the display unit 100 of the device based on the first input 11. Figure 2 is a flowchart of an embodiment of a screen control method according to the present invention. First, the first input 11 is applied to the display unit 100 (S100). When the first input 11 is applied to the display unit 100, the control unit 101 creates two virtual reference lines 1 and 2 in the display unit 100 based on the first input 11 (S200) ). As shown in FIG. 1, the first reference line 1 is an imaginary line drawn from the upper left of the first input 11 to the lower right of the first input 11, and the second reference line 2 is the first It is an imaginary line drawn from the bottom left of the input 11 to the top right of the first input 12. The first reference line 1 and the second reference line 2 may be displayed on the display unit 100 for user convenience. Depending on the user's settings, the shape of the first and second reference lines may have a curved shape, and the angle formed by each reference line may vary.

The control unit 101 creates an input area to which the second inputs 21, 22, 23, and 24 can be applied based on the first and second reference lines 1 and 2 (S300). In one embodiment according to the present invention, four input areas (31, 32, 33, and 34) appear. As shown in FIG. 1, the input area located above the first input 11 in the section divided by the first reference line 1 and the second reference line 2 becomes the first input area 31. In the same way, the input area located to the right of the first input 11 in the section divided by the first reference line 1 and the second reference line 2 becomes the second input area 32. The input area located below the first input 11 in the section divided by the first reference line 1 and the second reference line 2 becomes the third input area 33. The input area located to the left of the first input 11 in the section divided by the first reference line 1 and the second reference line 2 becomes the fourth input area 34.

While the first input 11 is applied, the display unit 100 receives the second inputs 21, 22, 23, and 24 (S400). The applied second input is transmitted to the control unit 101. Screen control according to the second input occurs according to the relative positions of the second inputs 21, 22, 23, and 24 shown in FIG. 1. The control unit 101 determines which input area the positions where the second inputs 21, 22, 23, and 24 are input belong to, and controls the display unit 100 according to the positions (S500). . When the location where the second input 21 is applied is the first input area 31, the control unit 101 scrolls the screen upward. In the same way, when the location where the second input 22 is applied is the second input area 32, the control unit 101 scrolls the screen to the right. When the location where the second input 23 is applied is the third input area 33, the control unit 101 scrolls the screen down. When the location where the second input 24 is applied is the fourth input area 34, the control unit 101 scrolls the screen to the left.

When the desired screen appears on the display unit 100, the user completes screen control by terminating the application of the first input 11.

In screen control according to an embodiment of the present invention, when the application of the second input is maintained for more than a certain period of time, the control unit 101 determines that the second input is applied and ends whenever the certain time elapses, and the display unit (100) can be controlled.

In screen control according to an embodiment of the present invention, when the user wants to return the screen displayed by the display unit 100 to the previous control while controlling the display unit 100, the user uses the second input (21, 22, 23, After terminating the application of the first input 11 while applying 24), the effect of the screen control can be canceled by applying the first input again and terminating the first input. Additionally, in another embodiment of the present invention, cancellation of the control operation of the display unit 100 may be accomplished by applying an input for dragging the display unit 100 to the first or second input.

In another embodiment of the present invention, the first input may be made by manipulating a button provided on the screen control device. When the button is pressed, it is recognized that the first virtual input is input in the center of the screen, and the first, second, third, and fourth input areas can be created in the above-described manner.

In another embodiment of the present invention, the second input may be achieved by tilting the screen control device. The user may apply the second input by tilting the screen control device while the first input is being applied. The control unit 101 may obtain the left, right, top, and bottom tilt values of the screen control device and then control the screen in the direction in which the difference in values is greatest based on the reference tilt value.

Additionally, in another embodiment of the present invention, the second input may be performed by giving a drag input to the display unit 100 using a pointing device such as a finger. As in the above-described embodiment, if a drag input is applied as a second input while the first input is being applied, the screen is scrolled with a larger width than the general screen scroll movement, or the control unit 101 changes the drag direction. By analyzing it, you can control the scrolling movement of the screen in the direction with the greatest change.
