A METHOD OF CONTROLLING TERMINAL DISPLAY WITH TWO FINGER}

The present invention relates to a terminal, and more particularly, to an apparatus and method for controlling a screen in a terminal having a document editing function.

Portable terminals are rapidly spreading due to the convenience of portability, and thus service providers (terminal manufacturers) are competitively developing terminals having more special functions to secure a large number of users. For example, a mobile terminal may include a phone book, a game, a scheduler, a short message, the internet, an e-mail, an alarm, and an mp3. Audio Layer-3), digital camera, electronic dictionary, e-book (e-book) and other functions are provided.

Recently, as one of the information providing media replacing the conventional paper book, an electronic book showing a text content by an electronic display method has emerged. The e-book is a method of displaying the text content stored on a display screen after storing the text content in a flash memory or an internal hard disk, and stores a large amount of book content at once and selects the content to be viewed. There is this.

In this case, only a limited area of content may be displayed through the display screen. Therefore, a user interface (UI) for providing page movement or scrolling function may be provided to continuously display the next content of the content. In general, the page down and page up functions using the key input means included in the e-book can be used to move the content of the text content and display it on the screen. You can read the full text.

However, the interface of turning pages through key manipulation is only the most basic form of direction control, and is not designed from the ergonomic point of view for the user's convenience. There is a problem that is inconvenient to switch

In addition, the method of moving the screen by gramming the screen with a finger has a large width for moving the screen, and if the screen is frequently moved, screen control is difficult and inconvenient to use.

Continuous input is when input is continuously applied. In one embodiment according to the present invention, the continuous input is a state in which a state in which a finger is pressed on the screen for a predetermined time or more is maintained. The reference time at which the continuous input is made can be set by the user.

Finger on is when your finger is touching the screen. Finger out is when your finger is off the screen. Finger on and finger out generate respective signals.

The screen control apparatus 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 inputs 21, 22, 23, and 24. The first input 11 is input to pointing means at any point of the display 100. The first input 11 may also consist of 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 also consist of touching the screen with the pointing means.

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

FIG. 1 illustrates a position at which second inputs 21, 22, 23, and 24 are input to the display unit 100 of the device based on the first input 11. 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 100, the controller 101 generates two virtual reference lines 1 and 2 on the display 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 lower left of the input 11 to the upper 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 ease of use of the user. According to a user's setting, the shape of the first reference line and the second reference line may have a curved shape, and an angle formed by each reference line may vary.

The controller 101 generates an input area to which the second inputs 21, 22, 23, and 24 may be applied based on the first reference line 1 and the second reference line 2 (S300). In an embodiment according to the present invention, four input regions 31, 32, 33, and 34 are shown. As shown in FIG. 1, the input area located above the first input 11 becomes a first input area 31 in a section divided by the first reference line 1 and the second reference line 2. 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. In a section partitioned by the first reference line 1 and the second reference line 2, the input area located below the first input 11 becomes the third input area 33. In the section partitioned by the first reference line 1 and the second reference line 2, the input area located to the left of the first input 11 becomes the fourth input area 34.

The display unit 100 receives the second inputs 21, 22, 23, and 24 while the first input 11 is applied (S400). The applied second input is sent to the controller 101. Control of the screen according to the second input occurs according to the relative positions of the second inputs 21, 22, 23, and 24 illustrated in FIG. 1. The control unit 101 determines which input area the position where the second inputs 21, 22, 23, and 24 are input belongs to and the control unit 101 controls the display unit 100 according to the position (S500). . When the position where the second input 21 is applied is the first input area 31, the controller 101 scrolls up the screen. In the same manner, when the position where the second input 22 is applied is the second input area 32, the controller 101 scrolls the screen to the right. When the position where the second input 23 is applied is the third input area 33, the controller 101 scrolls down the screen. When the position where the second input 24 is applied is the fourth input region 34, the controller 101 scrolls the screen to the left.

When the user desires to display the desired screen on the display unit 100, the user ends the control of the screen by terminating the application of the first input 11.

In the control of the screen according to an embodiment of the present disclosure, when the application of the second input is maintained for a predetermined time or more, the controller 101 determines that the second input is applied and terminates every time a predetermined time elapses and the display unit 100 can be controlled.

In the control of the screen according to an embodiment of the present disclosure, when the user attempts to return the screen displayed by the display 100 to the previous state while controlling the display 100, the second inputs 21, 22, 23, After the application of the first input 11 is terminated while applying 24), the effect of the screen control can be canceled by applying the first input again and ending the first input. Also, in another embodiment of the present disclosure, the control operation of the display unit 100 may be canceled by applying an input of dragging the display unit 100 to the first input or the second input.

In another embodiment of the present disclosure, the first input may be performed by operating a button provided in the screen control device. When the button is pressed, it is recognized that the virtual first input is input to the center of the screen, and the first, second, third, and fourth input areas may be generated in the above-described manner.

In another embodiment of the present disclosure, the second input may be made 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 controller 101 obtains the inclination values of the left, right, up, and down of the screen control apparatus, and then controls the screen in the direction in which the difference between the values is greatest based on the reference inclination value.

Also, in another embodiment of the present invention, the second input may be performed by giving a drag input to the display unit 100 by a pointing means such as a finger. When the drag input is applied to the second input while the first input is applied as in the above-described embodiment, the scroll movement of the screen is made larger than the scroll movement of the general screen, or the control unit 101 changes the drag direction. The scroll movement of the screen may be controlled by analyzing the direction having the largest change.
