Description

[0001] SCREEN CONTROL METHOD, TERMINAL, AND RECORDING MEDIUM [0002]

The present invention relates to a screen control technique.

Nowadays, terminals such as a smart phone, a tablet, a tablet, and a display that uses a screen touch as an input rather than a physical button operation are widely used.

Such a terminal employs a screen control technique for enlarging or reducing the screen displayed on the screen.

Conventional screen control techniques for screen enlargement and reduction include a pinch-to-zoom technique for enlarging or reducing the screen in such a manner as to widen or narrow the finger spacing by touching the screen with two fingers, And a technique of enlarging or reducing the screen by drawing a circle in a clockwise or counterclockwise direction by touching the screen with a finger.

FIG. 1 is a view showing a conventional screen control technique of a pinch zoom system.

Referring to FIG. 1 (a), when the user touches the screen with two fingers to spread the finger interval, the terminal recognizes that the "distance" between the two touches T1, T2 is distant. Accordingly, the terminal enlarges the screen according to the distances between the two touches (T1, T2) (D? D ', D <D').

Referring to FIG. 1 (b), when the user touches the screen with two fingers to narrow the finger interval, the terminal recognizes that the "distance" between the two touches T1 and T2 approaches. Accordingly, the terminal reduces the screen in accordance with the distance between the two touches T1 and T2 (D? D ', D> D').

In the case of the screen control technology of the pinch zoom method as shown in FIG. 1, in order to enlarge or reduce the screen, the user has to widen the finger interval to some extent so that the area covered by two fingers There is no disadvantage. This causes the user to feel inconvenience in viewing the screen.

FIG. 2 is a diagram showing a conventional screen control technique of a rotating system.

Referring to FIG. 2A, when a user touches a screen portion with a single finger and draws a circle in a clockwise direction, the terminal enlarges the screen when the rotation direction of one touch T1 is recognized as a clockwise direction .

Referring to FIG. 2B, when the user touches the screen with one finger and draws a circle in the counterclockwise direction, if the terminal recognizes that the rotation direction of one touch T1 is counterclockwise, .

In the case of the screen control technology of the rotation type as shown in FIG. 2, as compared with the conventional screen control technology of the pinch-to-zoom type shown in FIG. 1, although the screen enlargement / reduction is possible with only one touch, , The screen blinding problem of the conventional pinch-to-zoom type screen control technology may still occur due to the finger rotation radius. When the touch rotation for enlarging or reducing the screen is performed, the movement of the touch point moves the screen Or the like, the screen is not enlarged or reduced, and a malfunction occurs in which the screen is moved or handed over to another screen.

In such a background, the present invention enables an accurate and convenient enlargement / reduction of a screen without causing a large obstacle to be hidden by a finger or the like on the screen during a screen enlargement / reduction operation, And to provide a screen control technique using a new touch operation.

In one aspect, the present invention provides a display device including: a screen portion on which a screen is displayed; And a control unit for performing one of a screen zooming process for enlarging or reducing the screen and a screen moving process for moving the screen depending on whether the fixed touch is detected while the moving touch is being detected on the screen To the terminal.

In another aspect, the present invention provides a method of controlling a screen of a terminal, comprising: displaying a screen on a screen; And performing a screen zooming process for enlarging or reducing a screen in accordance with whether or not a fixed touch is detected while a moving touch is being detected on the screen or performing a screen moving process for moving a screen, &Lt; / RTI &gt;

According to another aspect of the present invention, there is provided a recording medium on which a program for executing a screen control method is recorded. The recording medium includes a function of displaying a screen on a screen, a function of detecting a fixed touch The present invention provides a computer-readable recording medium storing a program that implements a function of performing a screen zooming process for enlarging or reducing a screen and a screen moving process for moving a screen as a screen control process.

3 is a block diagram of a terminal 300 capable of screen control according to an embodiment of the present invention.

Referring to FIG. 3, a terminal 300 capable of controlling a screen according to an embodiment of the present invention includes a screen 310 on which a screen is displayed, A control unit 320 that performs one of the "screen zooming process" for screen enlargement or reduction and the "screen moving process"

Meanwhile, the terminal 300 capable of controlling the screen according to an embodiment of the present invention may further include a touch IC 330 for detecting whether or not a fixed touch and a moving touch are generated.

The "screen" described in the present specification means an object or data displayed on the screen unit 310 and may include, for example, a picture, an image, a moving picture, a web page, a DMB (Digital Multimedia Broadcasting) .

The "moving touch " (mT) described in the present specification is one touch event, and is a drag touch event in which the touch point moves in contact with the screen unit 320. [

The "fixed touch" (fT) described herein is a single touch event, which may be a touch event that presses one point on the screen 320 or a touch event whose touch point movement is restricted within a certain range.

The control unit 320 determines the type of the screen control process according to whether a fixed touch, which is another touch, is detected while the moving touch is being detected on the screen unit 310, and performs the type of the screen control process.

That is, when the fixed touch, which is another touch, is detected while the moving touch is being detected on the display unit 310, the control unit 320 performs a "screen zoom process" , And if the fixed touch is detected while the moving touch is being detected on the screen unit 310, the screen control process of the "screen moving process" can be performed.

More specifically, when the control unit 320 detects a fixed touch as another touch while the moving touch is being detected on the screen unit 310 and performs the screen zooming process as a screen control process, The screen is enlarged when the moving direction of the touch is a predetermined first direction and the screen is reduced when the moving direction of the moving touch is the predetermined second direction.

In other words, when the control unit 320 detects a fixed touch as another touch while the moving touch is being detected on the display unit 310 and performs the screen zooming process as a screen control process, The screen enlargement process is performed in the case of the predetermined first direction and the screen shrinking process is performed when the moving direction of the moving touch is the predetermined second direction.

The first direction and the second direction described in this specification are different directions, and the meaning may be changed depending on whether the screen control process is a screen zoom process or a screen movement process.

In the case of the screen zooming process, the first direction refers to the moving direction of the moving touch for screen enlargement, and the second direction refers to the moving direction of the moving touch for screen contraction.

For example, the first direction may be the upward direction (?) And the second direction may be the downward direction (?).

In another example, the first direction may be the right direction (?) And the second direction may be the left direction (?).

In another example, the first direction may be the left direction (?) And the second direction may be the right direction (?).

On the other hand, the first direction and the second direction may be determined depending on whether the screen mode is the landscape mode or the portrait mode.

In the case of the screen control process, the first direction and the second direction refer to the direction of moving or turning the screen.

On the other hand, when the control unit 320 detects a fixed touch as another touch while the moving touch is being detected on the screen unit 310 and performs the screen zooming process as a screen control process, It is possible to control the screen to be enlarged more as the movement length in one direction is longer and to control the screen to be less enlarged as the movement length in the first direction with respect to the movement touch is shorter. That is, the enlargement ratio can be changed according to the length of the moving distance in the first direction with respect to the moving touch.

In the case of screen reduction, the controller 320 detects a fixed touch, which is another touch while the moving touch is being detected on the screen 310. When the screen zooming process is performed as a screen control process, The screen can be controlled to be further reduced as the movement length in the second direction is longer, and the screen can be controlled to be smaller as the movement length in the second direction with respect to the movement touch is shorter. That is, the reduction ratio may vary depending on the length of the movement in the second direction with respect to the moving touch.

When the screen zooming process is performed as a screen control process, the control unit 320 determines whether the distance between the moving touch and the fixed touch is close to the moving distance, Accordingly, one of the screen enlargement process and the screen reduction process can be determined as the screen zoom process.

Therefore, the screen control according to the embodiment of the present invention is different from the screen control of the conventional pinch-to-zoom method.

That is, in the conventional pinch zoom zoom type screen control, the screen is enlarged only when the distance between the two touches is increased. However, in the embodiment of the present invention, Enlarge is possible.

In the conventional pinch zoom zoom type screen control, the screen is reduced only when the distance between the two touches is reduced. However, in the embodiment of the present invention, Screen reduction is possible.

On the other hand, when the control unit 320 does not detect a fixed touch that is another touch while the moving touch is being detected on the screen unit 310 and performs the screen moving process as a screen control process, When the moving direction of the moving touch is the second direction different from the first direction, the screen is moved in the second direction or the opposite direction To move to or away from the display.

On the other hand, each of the fixed touch and the moving touch can be detected in the entire area of the screen unit 310.

Alternatively, the fixed touch may be sensed in a first area of the screen unit 310, and the moving touch may be sensed in a second area of the screen unit 310.

For the convenience of the user, the first area where the fixed touch is sensed and the second area where the movement touch is sensed may be different depending on whether the use mode is the right-handed mode or the left-handed mode.

For example, when the use mode is the right-handed mode, the first area in which the fixed touch is detected is the left border area, and the second area in which the moving touch is detected may be the right border area.

When the use mode is the left-handed mode, the first area in which the fixed touch is sensed is the right edge area, and the second area in which the moving touch is sensed may be the left edge area.

Hereinafter, screen control according to the embodiment of the present invention described above will be exemplarily described with reference to Figs. 4 to 10, 11A and 11B.

4 and 5 are diagrams illustrating screen control according to an embodiment of the present invention. 4 is a view showing a screen zoom (screen enlargement, screen reduction) control. 5 is a diagram showing a screen movement control.

Referring to FIG. 4, for example, when a photo screen is displayed on the screen unit 310, a touch operation necessary for enlarging or reducing the photo screen is performed.

First, a touch operation by the user and a screen zoom process (screen enlargement process) for screen enlargement will be described with reference to FIG.

To enlarge the screen, the user touches the screen 310 with the finger of the right hand while touching the screen 310 with the finger of the left hand (the first direction for enlarging the screen) and drags the finger.

Accordingly, the terminal 300 senses the fixed touch (fT) by the finger of the left hand and senses the moving touch (mT1) in the first direction (the upward direction) by the finger of the right hand.

The terminal 300 performs a screen enlargement process for screen enlargement control during the screen zoom control because the fixed touch fT is being sensed while the movement touch mT1 in the first direction (upward direction) is sensed.

As a result, the picture screen displayed on the screen unit 310 is enlarged.

Meanwhile, the terminal 300 has a long movement length L1 of the movement touch mT1 in the first direction (upper direction) according to the length of the screen unit 310 in which the user drags the screen unit 310 in the first direction The enlargement ratio varies according to the shortness.

That is, the terminal 300 has a long movement length L1 of the movement touch mT1 in the first direction (upward direction) according to the length in which the user drags the screen unit 310 in the first direction (upward direction) The enlargement ratio is increased so as to be further expanded.

Next, a touch operation by the user and a screen zoom process (screen reduction process) for screen reduction will be described with reference to FIG.

In order to reduce the screen, the user touches the screen 310 with the finger of the right hand while dragging the screen 310 downward (the second direction for screen reduction) while pressing the screen 310 with the finger of the left hand.

Accordingly, the terminal 300 senses the fixed touch fT by the finger of the left hand and senses the moving touch mT2 in the second direction (downward) by the finger of the right hand.

The terminal 300 performs a screen reduction process for screen reduction control during the screen zoom control because the fixed touch fT is being sensed while the movement touch mT2 in the second direction (downward direction) is sensed.

Accordingly, the picture screen displayed on the screen unit 310 is reduced.

Meanwhile, the terminal 300 has a long movement length L2 of the movement touch mT2 in the second direction (downward direction) according to the length in which the user drags the screen unit 310 in the second direction (downward direction) The shortening reduces the reduction ratio.

That is, when the user moves the screen unit 310 in the second direction (downward direction), the movement length L2 of the movement touch mT2 in the second direction (downward direction) Increase the reduction ratio so that the number is more reduced.

Next, with reference to FIG. 5, a screen movement process during the screen control process and a touch operation of the user for the screen movement process will be described.

Referring to FIG. 5, in a state that a photo screen is displayed on the screen unit 310, a necessary touch operation is performed to move the photo screen to the side or to view the next or previous photo screen.

First, for screen movement other than screen enlargement, the user does not press the screen portion 310 with the finger of the left hand. That is, the terminal 300 prevents the fixed touch fT from being detected.

First, the movement of the screen in accordance with the moving touch to the upper direction (which may be the left or right direction as the first direction) will be described with reference to FIG.

The user touches and drags the screen 310 with the finger of his right hand in the upward direction (which may be the first direction, the left direction, the right direction, or the like).

Accordingly, the terminal 300 senses only the moving touch mT1 in the first direction (upper direction) by the finger of the right hand.

The terminal 300 does not perform the screen zoom control because the fixed touch fT is not detected while the moving touch mT1 in the first direction A screen movement process for screen movement control in the opposite direction (downward direction) of one direction is performed.

Accordingly, the picture screen displayed on the screen unit 310 moves on the screen. In the example of FIG. 5, the photograph screen moves up in the upward direction on the screen unit 310 according to the upward movement mT1, and a portion that is not seen from the bottom portion is displayed on the screen unit 310 do.

Next, the screen movement in accordance with the moving touch to the downward direction (which may be the right or left direction as the second direction) will be described with reference to FIG.

The user touches and drags the screen 310 with the finger of his right hand in the downward direction (which may be the right or left direction as the second direction).

Accordingly, the terminal 300 senses only the moving touch mT2 in the second direction (downward direction) by the finger of the right hand.

Since the fixed touch fT is not detected while the movement touch mT2 is detected in the second direction (downward direction), the terminal 300 does not perform the screen zoom control, And performs a screen movement process for controlling the screen movement in the opposite direction (upward direction) of the two directions.

Accordingly, the picture screen displayed on the screen unit 310 moves on the screen. In the example of FIG. 5, the photograph screen moves downward from the screen unit 310 in a downward direction according to the downward movement touch mT2, and a portion that is not seen from the top moves on the screen unit 310 do.

FIG. 6 is a diagram illustrating two touch sensing areas for a screen zoom process according to an exemplary embodiment of the present invention. Referring to FIG.

As described above, in order to perform the screen zooming process according to the embodiment of the present invention, two kinds of touches (fixed touch (fT), moving touch (mT)) are required.

6A, two kinds of touches (the fixed touch fT and the moving touch mT) can be detected in the entire area Aall of the screen part 310. [

6B, the two touches (the fixed touch fT and the moving touch mT) can be sensed in different areas of the screen unit 310. In addition, as shown in FIG.

Referring to FIG. 6B, for example, the fixed touch fT may be sensed in the left border area Aleft, and the moving touch mT may be sensed in the right border area Aright.

The detection position of the fixed touch fT and the movable touch mT is different only from the position at which the user sets the fixed touch fT and the movable touch mT, May be the entire area.

Otherwise, in some cases, the detectable area of each of the fixed touch fT and the movable touch mT may be limited to the left border area Aleft and the right border area Aright, respectively.

FIGS. 7 and 8 are exemplary views of a screen enlargement process and its touch operation during a screen zoom process according to an embodiment of the present invention.

FIG. 7 is an exemplary view in which a user touch is performed to enlarge the screen so that the distance between the fixed touch fT and the moving touch mT is increased.

7, in order to enlarge the screen, the user holds the screen 310 in the upward direction (first direction) with the finger of the right hand while pressing one point of the screen 310 with the finger of the left hand Drag.

Accordingly, the terminal 300 senses the moving touch (mT) by the finger of the right hand while sensing the fixed touch (fT) by the finger of the left hand. Accordingly, the screen zoom control is performed during the screen control.

The terminal 300 senses the movement touch mT by the finger of the right hand and detects the movement touch mT in the first direction (e.g., upward direction) in which the movement direction is predetermined. Therefore, Thereby performing enlargement control.

On the other hand, in order to enlarge the screen, the user drags the screen portion 310 in the first direction (for example, the upper direction) with the finger of the right hand while pressing one point of the screen portion 310 with the finger of the left hand The distance between the fixed touch fT and the moving touch mT is shifted from Dshort to Dlong due to the position of the fixed touch fT and the initial position of the movement touch mT and the movement direction of the movement touch mT (Dshort → Dlong, Dshort <Dlong).

FIG. 8 is an exemplary view in which a user touch is performed to enlarge a screen so that the distance between the fixed touch fT and the moving touch mT is approached.

Referring to FIG. 8, in order to enlarge the screen, the user drags the screen 310 with the finger of the right hand while holding one point of the screen 310 with the finger of the left hand.

Accordingly, the terminal 300 senses the moving touch (mT) by the finger of the right hand while sensing the fixed touch (fT) by the finger of the left hand. Accordingly, the screen zoom control is performed during the screen control.

The terminal 300 senses the movement touch mT by the finger of the right hand and detects the movement touch mT in the first direction (e.g., upward direction) in which the movement direction is predetermined. Therefore, Thereby performing enlargement control.

On the other hand, in order to enlarge the screen, the user drags the screen portion 310 in the first direction (for example, the upper direction) with the finger of the right hand while pressing one point of the screen portion 310 with the finger of the left hand The distance between the fixed touch fT and the moving touch mT is close to Dshort from Dlong due to the position of the fixed touch fT and the initial position of the movement touch mT and the movement direction of the movement touch mT (Dlong → Dshort, Dlong> Dshort).

This is different from the conventional method in which the distance between the two moving touches is increased in the screen enlargement of the conventional pinch zoom method.

The reason for this is that, in the case of the screen control of the conventional pinch zoom method, it is determined whether to enlarge or reduce the screen in accordance with a distance change in distance (finger interval) between two moving touches. It is determined whether the screen is enlarged or reduced only by the moving direction of one moving touch while one fixed touch is detected, regardless of a distance change between the one fixed touch and the one moving touch.

FIG. 9 and FIG. 10 are exemplary views of a screen reduction process and a touch operation of the screen zoom process according to an exemplary embodiment of the present invention.

FIG. 9 is an exemplary view in which a user touch is performed to reduce the screen so that the distance between the fixed touch fT and the moving touch mT is approximated.

9, in order to reduce the screen, the user holds the screen 310 in the downward direction (second direction) with the finger of the right hand in a state of pressing one point of the screen 310 with the finger of the left hand Drag.

Accordingly, the terminal 300 senses the moving touch (mT) by the finger of the right hand while sensing the fixed touch (fT) by the finger of the left hand. Accordingly, the screen zoom control is performed during the screen control.

The terminal 300 senses the movement touch mT by the finger of the right hand and detects the movement touch mT in the second direction (e.g., downward direction) in which the movement direction is predetermined. Therefore, Reduction control.

On the other hand, in order to reduce the screen, the user drags the screen portion 310 in the second direction (e.g., downward) with the finger of the right hand while pressing one point of the screen portion 310 with the finger of the left hand The distance between the fixed touch fT and the moving touch mT is close to Dshort from Dlong due to the position of the fixed touch fT and the initial position of the movement touch mT and the movement direction of the movement touch mT (Dlong → Dshort, Dlong> Dshort).

10 is an exemplary view in which a user touch is performed for reducing the screen so that the distance between the fixed touch fT and the moving touch mT is increased.

10, in order to reduce the screen, the user holds the screen 310 in the downward direction (second direction) with the finger of the right hand in a state of pressing one point of the screen 310 with the finger of the left hand Drag.

Accordingly, the terminal 300 senses the moving touch (mT) by the finger of the right hand while sensing the fixed touch (fT) by the finger of the left hand. Accordingly, the screen zoom control is performed during the screen control.

The terminal 300 senses the moving touch mT by the finger of the right hand and detects the moving touch mT in the second direction (e.g. downward direction) .

On the other hand, in order to enlarge the screen, the user drags the screen portion 310 in the second direction (e.g., downward direction) with the finger of the right hand while pressing one point of the screen portion 310 with the finger of the left hand The distance between the fixed touch fT and the moving touch mT is shifted from Dshort to Dlong due to the position of the fixed touch fT and the initial position of the movement touch mT and the movement direction of the movement touch mT (Dshort → Dlong, Dshort <Dlong).

This is different from the conventional approach in which the distance between the two moving touches is reduced in the screen reduction of the pinch zoom system.

The reason for this is that, in the case of the screen control of the conventional pinch zoom method, it is determined whether to enlarge or reduce the screen in accordance with a distance change in distance (finger interval) between two moving touches. It is determined whether the screen is enlarged or reduced only by the moving direction of one moving touch while one fixed touch is detected, regardless of a distance change between the one fixed touch and the one moving touch.

FIGS. 11A and 11B are diagrams showing that a screen movement process and a screen zoom process are continuously performed during a screen control process according to an embodiment of the present invention.

11A and 11B illustrate a case in which the user views the A picture (screen) through the screen unit 310, passes the B picture to the next B picture, enlarges and reduces the B picture, ((A) to (h)).

When the user wants to view the next B picture screen in a state that the A picture screen is displayed on the screen unit 310, as shown in (a) of FIG. 11, It is only necessary to perform a touch operation of dragging the touch panel 310 in the upward direction. Here, the drag of the user is the moving touch (mT).

Thus, as shown in FIG. 11A (b), the next photographic screen (B photographic screen) on the A photographic screen is displayed on the screen portion 310.

Then, as shown in Fig. 11A, (b), the user views the B picture screen and enlarges the B picture. As shown in (c) of Fig. 11, (E.g., the upper direction) with the finger of the right hand (e.g., the thumb) in a state in which the screen 310 is pressed with the thumb . Here, pressing the screen 310 with a finger of the left hand (e.g., a thumb) is a fixed touch fT and moving the screen 310 with a finger (e.g., a thumb) of the right hand in a predetermined first direction : Upward direction) is the moving touch (mT).

Thus, as shown in (d) of Fig. 11A, the finger of the right hand (e.g., the thumb) is moved by the enlargement ratio corresponding to the length in which the screen portion 310 is dragged in the first direction B The picture screen is enlarged.

On the other hand, when the enlarged B picture screen is to be reduced again as shown in (d) of Fig. 11A, the user can use the left hand finger (e.g., thumb) A touch operation of dragging the screen portion 310 in a predetermined second direction (e.g., downward direction) with a finger (e.g., a thumb) of the right hand may be performed. Here, pressing the screen 310 with a finger (e.g., a thumb) of the left hand is a fixed touch fT and moving the screen 310 to a predetermined second direction (e.g., : Downward direction) is the moving touch (mT).

Thus, as shown in (f) of FIG. 11B, the finger (e.g., a thumb) of the right hand is moved by the reduction ratio corresponding to the length in which the screen portion 310 is dragged in the second direction B The picture screen is displayed in a reduced size.

11B, when the user wishes to view the next picture screen (C picture screen) on the B picture screen, the user uses the finger of the right hand (e.g., thumb) Only the touching operation of dragging in the upward direction can be performed. Here, the drag of the user is the moving touch (mT).

Thus, as shown in (h) of FIG. 11B, the next picture screen (C picture screen) on the B picture screen is displayed on the screen unit 310. [
