Description

Character input interface using skin type interface and touch screen device implementing the same {METHOD AND TOUCH SCREEN DEVICE FOR IMPLEMENTING CHARACTER INPUTTING INTERFACE USING SKIN TYPE INTERFACE}

The present invention relates to a method of implementing a text input interface using a skin-type interface and a touch screen device implementing the same.

As the spread of devices using a touch screen, such as a smartphone, a tablet computer, an ATM device, and the like, it is frequently required to input characters on the touch screen in daily life. Such a touch screen is directly touched on a keyboard or keypad displayed on the screen to receive characters such as Korean, English, numbers, and special symbols to perform processing according to the purpose.

In general, when looking at an example of a touch screen device such as a smart phone, the keyboard on the touch screen is output when character input is required, and is generally disposed at the bottom of the screen to occupy about half the area of the screen. In this case, the user may directly input the corresponding character by directly touching the keyboard in the screen.

However, the keyboard displayed on the touch screen has a limited size according to the size of the touch screen, unlike other real keyboards, and due to the limitation of touch input due to the characteristics that must be implemented on a flat surface, different character keys may be used for the sense of a finger. There is a problem that cannot be distinguished.

In particular, in the case of a small mobile device such as a smart phone, since a small letter key is touched and input with only one finger or two fingers, a large number of input mistakes are generated and inconvenience of lowering an input speed is greatly generated.

As such, in order to overcome limitations in implementing an input interface of a touch screen device, Korean Patent No. 1021757 shows a curved slide bar having a predetermined length on a screen of a touch screen, and a drag is made along the slide bar. A touch screen interface control device for performing a corresponding control is proposed.

However, the touch screen interface control device performs at least one of a sound-related control or a playback-related control operation of a multimedia file as the slide bar is dragged, and the range of utilization of the touch screen interface control device does not solve a problem when inputting a text. .

An embodiment of the present invention is to provide a character input interface implementation method using a skin-type interface having an extended interface screen utilization in implementing the character input interface of the touch screen device, and a touch screen device implementing the same.

As a technical means for achieving the above-described technical problem, a touch screen device for implementing a character input interface using a skin type interface according to an aspect of the present invention, a skin type interface that is movable on a fixed basic interface screen of the touch screen A display unit for overlapping and outputting a screen; An input detector configured to detect a touch and dragging generated on the touch screen and generate a screen motion input value according to the touch and dragging; The skin type interface screen is controlled to move according to the direction and distance of the dragging based on the screen operation input value, and the pointer object disposed on any one of the skin type interface screen and the basic interface screen according to the movement. A skin type interface controller which determines whether an overlap occurs between an area and a region of a plurality of character keys disposed on the other interface screen on which the pointer object is not disposed; And a selection character input unit for generating an input by selecting a character key corresponding to the overlap when the overlap occurs.

In addition, the method for implementing a character input interface using a skin type interface according to another aspect of the present invention includes: outputting a superimposed basic interface screen and a movable skin type interface screen on a touch screen; Detecting contact and dragging generated on the touch screen; Moving the skin type interface screen according to the direction and distance of the dragging; An area of at least one pointer object disposed on any one of the basic interface screen and the skin type interface screen, and a plurality of character keys disposed on the other interface screen on which the pointer object is not disposed Determining whether an overlap occurs between any one region; And generating an input by selecting a character key corresponding to the generated overlap when the overlap occurs.

According to any one of the problem solving means of the present invention described above, a character key can be input only by dragging after touching the entire or most of the area of the touch screen (that is, the skin type interface screen). This is convenient.

And, according to any one of the problem solving means of the present invention, it is possible to touch the arbitrary area of the touch screen screen without touching the character key to input directly, and then drag to input the corresponding character, thereby making a mistake of wrongly pressing the character key. Can be greatly reduced.

In addition, by placing a plurality of pointer keys for selecting a character key keyboard and a character key on the touch screen, the dragging distance may be minimized to increase the speed and convenience of the input.

At this time, the display unit 130 moves the skin type interface screen or outputs a screen according to data processing generated by the touch screen device 100 under the control of the skin type interface controller 120.

Hereinafter, the basic interface screen and the skin type interface screen output on the touch screen of the touch screen device 100 through the display unit 130 will be described in detail with reference to FIGS. 2 to 6.

The basic interface screen and the skin type interface screen output on the screen of the touch screen device 100 may be implemented as shown in FIG. 2.

2 is an example for describing a touch screen screen according to an embodiment of the present invention.

In detail, as shown in FIG. 2, the fixed basic interface screen P210 and the movable skin type interface screen P220 are overlapped and touched on the touch screen device 100 according to an embodiment of the present invention. Output to the screen screen. For reference, as illustrated in FIG. 2, the transparency of the skin type interface screen P220 may be set so that the basic interface screen P210 may be reflected.

In this case, in FIG. 2, a text input window P211 through which inputted characters are output on the basic interface screen P210 and a plurality of text objects that can be selected by the user (hereinafter, referred to as 'character keys') (P212 and P213). ) Is shown. In addition, in FIG. 2, two pointer objects P221 and P222 for selecting the character keys P212 and P213 may be selected from the skin type interface screen P220 of the skin type interface screen P220 and the basic interface screen P210. It was shown to be configured spaced apart from the center by a predetermined arrangement distance.

In addition, as shown in FIG. 2, the plurality of character keys P212 and P213 configured on the basic interface screen P210 may be arranged in the form of a keyboard, and the keyboard may include at least one letter key group. In FIG. 2, two letter key groups (ie, keyboard shapes) are divided into upper and lower portions P212 and P213 on the basic interface screen, respectively. The arrangement position of the character key keyboard is not limited thereto, and a plurality of character key groups may be disposed to face each other. In this way, the character key keyboard is classified into a plurality of groups and arranged at positions spaced apart from each other, and the pointer objects P221 and P222 and the character keys P212 and 213 are arranged by being spaced apart from each other. The dragging distance of the liver can be narrowed and become constant. That is, efficient dragging may be performed to move the skin type interface screen P220 to select a character key.

In addition, as illustrated in FIG. 2, at least one special key button P223 may be configured on the skin type interface screen P220. In this case, FIG. 2 shows that a special character conversion button, a character attribute conversion button, a shift key button, a backspace key button, a space key button, and an enter key button are configured on the skin type interface screen P220.

In addition, as shown in FIG. 2, the center display object P224 may be configured on the skin type interface screen P220 to identify the center. The midpoint display object P224 allows the user to easily recognize the movement of the skin type interface screen P220 so that dragging is convenient. In addition, the midpoint display object P224 becomes a reference area to return to the basic position after dragging the skin type interface screen P220. In this case, the midpoint display object P224 is positioned in an area where the centers of the basic interface screen P210 and the skin type interface screen P220 overlap with each other when initially set.

Meanwhile, in FIG. 2, character keys P212 and P213 are configured on the basic interface screen P210 according to an embodiment of the present invention, and the character keys P212 and P213 may be selected on the skin type interface screen P220. The pointer objects P221 and P222 may be configured.

However, in the touch screen device 100 according to another exemplary embodiment of the present disclosure, the letter keys P212 and P213 and the pointer objects P221 and P222 may be configured in reverse. Specifically, as shown in (b) of FIG. 3, pointer objects P221 and P222 are configured on the basic interface screen P210, and text keys P212 and P213 are configured on the skin type interface screen P220. It is also possible.

3 is an example for explaining the configuration of a skin-type interface screen according to an embodiment of the present invention.

On the touch screen of the touch screen device 100 according to an embodiment of the present invention, as shown in FIG. 3A, a basic interface including a text input window P211 and a letter key keyboard P212 and P213 is provided. The skin type interface screen P220 including the screen P210, the plurality of pointer objects P221 and P222, the plurality of special key buttons P223, and the midpoint display object P224 may be output.

In addition, on the touch screen of the touch screen device 100, as illustrated in FIG. 3B, a basic interface screen P210 including a plurality of pointer objects P212-1 and P213-1, and a text key The skin type interface screen P220 including the keyboards P221-1 and P222-1, the plurality of special key buttons P223, and the midpoint display object P224 may be output.

On the other hand, the character key keyboard according to an embodiment of the present invention may be set in various types to increase the character input speed of the user and to facilitate the operation.

4 and 5 are views for explaining an example of the character key keyboard according to an embodiment of the present invention.

4 and 5 illustrate that the character key keyboard and the pointer object configured on the basic interface screen or the skin type interface screen are arranged in various forms.

First, as shown in (a) of FIG. 4, two letter key keyboards P251 are respectively arranged in a curve toward the midpoint display object and the pointer object. As such, when the character key keyboard is arranged in a curve, the distance from the pointer object may be constant for each character key, thereby enabling efficient dragging.

In addition, as shown in (b) of FIG. 4, two letter key keyboards may be vertically arranged on both sides of the touch screen. In this case, two pointer objects may be disposed horizontally to be close to the vertical character key keyboard, and special key buttons may be disposed above and below the center display object for the selection speed and convenience of screen movement for the character key keyboard. have.

5 (a) and 5 (b) show that the character key keyboard P252 is a qwerty type.

QWERTY type keyboard means that the key is not arranged in the original order of letters or numbers to increase the input speed of the letter key, but is arranged in order to facilitate user input. In addition, in Fig. 5B, the character key keyboard P253 is subjected to multiple steps to show that the character keys are arranged to have a differential height. In this way, the user can easily generate overlapping with the pointer object for each character key even in the same character key group. That is, a qwerty array can be provided in consideration of the key arrangement of a keyboard familiar with general keyboard usage.

6 is a view for explaining an example of a special button according to an embodiment of the present invention.

As illustrated in FIG. 6, a plurality of special key buttons P223 may be configured at a position spaced apart from the pointer object by a predetermined distance on the skin type interface screen P220.

In this case, the special character conversion button is a button for converting a character key keyboard into special characters such as numbers, figures, and characters, and the character property conversion button is a character attribute (ie, English, Chinese) on the character key keyboard selected as the character. , Hangul, etc.) button to convert and use, the shift key button is a button for selecting any one of two or more characters matched to one character key to expand the number of character keys, the backspace key The button is a button for erasing input characters, the space key button is a button for increasing a space between characters, and the enter key button may be a button for executing a control process on the input characters.

As such, the special key button P223 is configured on the skin-type interface screen P220, since the contact generated on the touch screen is actually generated on the skin-type interface screen P220, so that the special key button P223 may be used to control the character key keyboard. This is because the manipulation of the special key buttons P223 should be possible on the skin type interface screen P220.

For example, as illustrated in FIG. 6, the user may contact the shift key button P223-1 on the skin type interface screen P220 to select the shift key button P223-1. In this case, as shown in FIG. 6, the selected shift key button P223-1 may be changed into an active state and output. For reference, when the character keys P212 and P213 are converted after pressing the shift key button P223-1, and the character keys P212 and P213 are converted only when the shift key buttons P223-1 are pressed. It can be divided into cases.

1, the input detector 110 detects contact and dragging generated on the touch screen to generate a screen operation input value according to the contact and dragging to the skin type interface controller 120. To pass. In practice, the contact and dragging generated on the touch screen are generated on the skinned interface screen P220.

The skin type interface controller 120 controls the skin type interface screen to be moved according to the direction and distance of dragging based on the screen operation input value.

The skin type interface controller 120 may further include an area of at least one pointer object configured on any one of the skin type interface screen or the basic interface screen according to the movement, and the other interface on which the pointer object is not configured. It is determined whether an overlap occurs within a predetermined reference distance between areas of at least one letter key configured on the screen. For reference, the area of the character key may be set above or below the size of the actual character key.

At this time, the skin type interface controller 120 transmits the result of the determination to the selection character input unit 140. For reference, the reference distance may be a distance range preset in the outward direction based on the center of each letter key.

In addition, the skin type interface controller 120 does not generate another contact or dragging or the pointer object within the reference distance until the preset overlapping retention time elapses after the overlap between the at least one pointer object and the character key is generated. If the location is consistent, it may be determined that overlap has occurred.

Meanwhile, the skin type interface controller 120 may control to change the state of the text key in which the overlap occurs to an active state. For reference, in the activated state, the state of the character key is changed to be identified with the general state before the overlapping occurs.

In addition, the skin type interface controller 120 may return the skin type interface screen to a preset default position before the dragging after the selection of the active object. For reference, the basic position may be set to a position where the midpoint display object overlaps the center of the basic interface screen. As such, as the skin type interface screen is returned to its original position after the input of the character key, the speed and the operation of selecting the character key to be input next are convenient. For reference, the skin type interface screen may return to the home position immediately without moving according to the moving trajectory, or may move according to a preset return direction (that is, the moving trajectory) to return to the home position.

The selection character input unit 140 selects a character key corresponding to the overlap and generates an input based on a result of the determination received from the skin type interface controller 120.

In this case, the selection character input unit 140 generates an input by selecting a corresponding character key when a preset operation holding time elapses after at least one of the termination of the contact on the touch screen and the stopping of dragging occurs after the overlap occurs. You can. The selected text input unit 140 may transmit a text value to the display 130 so that the text corresponding to the selected text key is output through the text input window of the basic interface screen.

Hereinafter, a method of inputting a character key using a skin type interface according to an embodiment of the present invention will be described in detail with reference to FIGS. 7 and 8.

7 is an example for describing a character key input process using a skin type interface according to an embodiment of the present invention.

First, as shown in (a) of FIG. 7, in a basic state in which a basic interface screen and a skin type interface screen are overlapped and output on a touch screen, as shown in FIG. When the skin type interface screen is dragged, the upper pointer object of the two pointer objects overlaps with the letter key 'g', and the object P300 is activated. When the contact ends or the dragging ends in the activated state, the letter 'g' is input to the letter input window P211 as shown in FIG.

In addition, when the dragging or touching of the touch screen is terminated, the skinned interface screen is returned to the direction of the arrow (ie, the Y-axis downward), and the pointer object that has overlapped with the letter key 'g' is released.

In this case, although the dragging or contacting is terminated in FIG. 7, the skin type interface screen is returned to its original position. However, the user can directly drag the skin type interface screen in the direction of the arrow (ie, down the y axis) to select the next character key. It is also possible to operate. For example, it is possible to omit step (c) in FIG. 7 and to perform step (d) directly from step (b). That is, the contact and dragging may be performed on the skin type interface screen P220 again before the skin type interface screen P220 is returned to its original position after the dragging or the touch screen is terminated.

In addition, as shown in (d) of FIG. 7, when the skin type interface screen, which has been returned to its original position, is dragged again in the direction of an arrow (that is, upward diagonally right), the upper pointer object of the two pointer objects is the letter key ' Overlapping with h ', the active object is displayed. When the contact or the dragging ends in the activated state, the letter 'h' is input to the letter input window P211 as shown in FIG.

In addition, when the dragging or touching of the touch screen is terminated, the skinned interface screen is returned to the direction of the arrow (that is, downward diagonally left), and the pointer object that has overlapped with the letter key 'h' is released. In this case, when step (c) is omitted in FIG. 7 and is directly performed in step (d) to step (d), the character key 'g' becomes activated after the overlap of the letter key 'g' and is dragged immediately. Is generated and an overlap for the letter key 'h' is generated, and the letter key 'h' may be activated.

In this manner, the character key of the character key keyboard disposed on the upper and lower portions of the touch screen may be selected by dragging the skin type interface screen.

Meanwhile, FIG. 7 illustrates that the pointer object is configured on the skin type interface screen while the character key keyboard is configured on the basic interface screen and the position of the character key is fixed. That is, in FIG. 7, the pointer object moves with the movement of the skin type interface screen, and overlaps with the character keys.

However, as shown in FIG. 8, in the state where the pointer object is configured on the basic interface screen and the pointer object is fixed, the character key keyboard may be configured on the skin type interface screen. At this time, according to FIG. 8, the character key keyboard moves as the skin-type interface screen moves, and overlaps with any one of the pointer objects.

8 is an example for explaining a character key input process using a skin type interface according to another embodiment of the present invention.

First, as shown in (a) of FIG. 8, in a basic state in which the basic interface screen and the skin type interface screen are overlapped and output on the touch screen, as shown in FIG. When the skin type interface screen is dragged, the character key 'g' on the upper character key keyboard and the upper pointer object among the pointer objects are overlapped and the active object P300 is output. . When contact or dragging is terminated in the active state, the letter 'g' is input to the letter input window P211 as shown in FIG.

For reference, the skin type interface controller 120 controls the text key to be converted into an active state. When the text key is configured on the basic interface screen, the skin type interface controller 120 activates the text key on the basic interface screen to the activated state. A control command to change can be sent. In addition, when the text key is configured on the skin type interface screen, the skin type interface controller 120 may transmit a control command to the display 130 to change the text key on the skin type interface to an active state.

When the dragging or touching of the touch screen is terminated, the skin-type interface screen is returned to the direction of the arrow (that is, the Y-axis upward), and the letter key 'g' that overlaps with the upper pointer object is released.

Hereinafter, a method of implementing a character input interface using a skin type interface according to an embodiment of the present invention will be described in detail with reference to FIG. 9.

9 is a flowchart illustrating a method of implementing a character input interface using a skin type interface according to an embodiment of the present invention.

First, a character key interface and a pointer object interface are output on the touch screen (S910).

In this case, the text key interface and the pointer object interface are configured on a basic interface screen and a skin type interface screen that are overlaid on the touch screen, and are configured on different interface screens.

Then, the touch and drag generated on the touch screen is sensed (S920).

In operation S930, the skin type interface is moved according to the drag direction (and distance) based on the detected contact and drag.

 Then, the occurrence of overlap between the point area and the character key area is detected (S940).

Specifically, within a predetermined reference distance between an area of at least one pointer object configured on the skin type interface screen or the basic interface screen and at least one letter key area configured on the other interface screen on which the pointer object is not configured. Determine if overlap occurs.

In this case, the state of the overlapped character key may be controlled to be changed to an activation standby state and output. At this time, in the activation standby state, the character key is changed on the corresponding interface screen to be identified with the general state before the overlap occurs.

Then, the overlapping character key (that is, the overlapping object) is selected as the input character (S950).

Meanwhile, according to an embodiment of the present disclosure, the selection may be performed after a preset operation holding time elapses after at least one of the termination of the contact and the stopping of the dragging occurs after the occurrence of the overlap.

In addition, when implementing the user interface using the skin-type interface according to an embodiment of the present invention, after step S950, the step of returning the skin-type interface screen to the basic position before the dragging may be further performed. For reference, the basic position may be a position where the center of the skin type interface screen overlaps with the center of the basic interface screen.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be.
