Description

Character input terminal by recognization of divided drag region, server for downloading application program}

The present invention provides a drag area recognition type text input terminal for splitting a touch screen into a plurality of different drag areas based on each button, and generating and displaying characters by analyzing drag patterns formed along the divided drag areas. It relates to a server for providing a downloadable application used for.

In general, various devices including smart phones, computing guides installed in public places, and various keyboards include character input devices.

These various text input devices display text by receiving a command from a user for SMS and messenger use or information search. For this, a touch screen is typically used.

The touch screen receives characters by using a method such as detecting a movement by a sensor even if the touch screen is not directly contacted by using a hand or a touch pen. Of course, it also receives a command for selecting various additional functions in addition to the text.

Meanwhile, when a character is input through a touch screen, a consonant and a vowel must be selected. In this case, a technique of pressing a consonant button and then dragging the consonant button in a specific pattern to select a plurality of different vowels is provided.

For example, in Korean Patent Application No. 2007-0018984, as shown in FIG. 1, a vowel corresponding to the length can be selected by analyzing lengths dragged in a specific direction based on a button.

However, this method is difficult for the user to drag exactly as long as the length. That is, the vowel 'l', 'ㅏ' and 'ㅑ' should be dragged in the same direction, but with different lengths.

Therefore, if the length of the drag is a little long or short, the wrong vowel is not selected or not selected at all, and it is cumbersome and takes a long time since the drag attempt is made several times for inputting a vowel.

In addition, even if the drag is mastered by using the smart phone for a long time, there is still the above difficulty in the shaking space such as inside the vehicle.

In addition, there is a problem that does not provide an ergonomic drag environment suitable for the user's hand. For example, when holding a smart phone and dragging it with a thumb, it is comfortable and natural to have a slightly curved body structure, but conventionally, there is a problem of recognizing only a straight drag.

The reason for recognizing only straight drag is to set an imaginary reference line made of straight lines on the screen touch, and recognize the input only when dragging is performed along the reference line.

As another example, in Korean Patent Application No. 2010-0057172, as shown in FIG. 2, the user drags in a specific direction based on a button, and at this time, different vowels can be selected according to the number of times of repeated dragging.

However, this method is time-consuming and cumbersome because the user has to drag several times. In other words, to input the vowel 'ㅐ', 4 drags are required. Moreover, if the drag is wrong, you have to cancel it and drag it four times from the beginning.

You can also enter a vowel by dragging diagonally from the corner of the button, but this must be done exactly along the baseline set radially around the button. Therefore, if the deviation from the diagonal reference line there is a problem that the drag is not made or other vowels are selected.

As another example, in Korean Patent Application No. 2010-0091431, as shown in FIG. 3, when a drag is changed to various patterns, a specific vowel can be selected according to the pattern.

Therefore, in order to input 'ㅐ', dragging in the direction of 'ㄱ', thus improving convenience to some extent than other character input methods described above.

However, such a method also does not provide an ergonomic drag environment because it recognizes only a linear drag, or still has the same problem as having to drag a plurality of times in the same direction.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problem, and it is intended to provide a drag area recognition type text input terminal and a downloadable application program used for implementing the vowel that can easily and easily reduce the selection error. .

In addition, the present invention can select the vowel by analyzing the drag in the curve direction according to the characteristics of the human body structure as well as the linear drag, drag area recognition type character input terminal for easy mastery of character input and downloads used in the implementation We want to provide a server to provide possible applications.

To this end, the drag area recognition type character input terminal according to the present invention includes a drag area divider for dividing a range of a predetermined width centered on a button displayed on a screen of a touch screen into a plurality of areas; A drag analyzer configured to analyze a drag of a user along the drag area; And a character generation unit receiving the drag analysis result to generate and display a character.

In this case, the drag area dividing unit divides the drag area around the selected button among the buttons displayed on the screen of the touch screen, and the character generation unit is configured to the consonant assigned to the selected button and the pattern analyzed by the drag analyzing unit. It is desirable to combine the corresponding vowels to generate characters.

The drag region dividing unit divides the inside and the outside of the button into different drag regions (first region division), and divides the outside of the button into different drag regions with extension lines extending from each side of the button. 2 area division).

The apparatus may further include a touch point comparator configured to compare the point at which the button is touched with the center point of the button, wherein the drag area divider is configured to touch the touched point when the point at which the button is touched does not coincide with the center point of the button. Preferably, the drag area is divided based on a virtual button serving as a center point.

In addition, it is preferable that the extension line used for dividing the second area is set so that the width formed by two extension lines parallel to each other becomes wider as the distance from the button increases.

The drag area dividing unit may divide the third area by dividing the corner area of the button into different drag areas.

The drag area dividing unit may divide the drag area by using a diagonal diagonal line as a boundary line of each corner of the button.

In addition, the drag analysis unit may distinguish between the case where the drag starts at each corner of the button and the case where the drag does not start at each corner of each button, and analyzes with a different command according to each of the divided cases. Do.

On the other hand, the server of the present invention is characterized in that when the drag area recognition type character input terminal downloads the downloadable application program in the terminal, and implements the downloadable application program.

Hereinafter, a drag area recognition type text input terminal and a server for providing a downloadable application program used for implementing the same will be described in detail with reference to the accompanying drawings.

However, hereinafter, a smart phone as an example of a text input terminal will be described. However, the present invention can be applied to any terminal requiring character input, including an electronic guide board or various touch keyboards installed in public places.

First, as shown in FIG. 4, the smart phone provides a touch screen for text input. Since a plurality of character input buttons, that is, a keypad, are displayed on the touch screen, a desired character is input. This provides various services such as SMS, MMS, mobile messenger and information search.

The touch screen receives characters by using a hand or a touch pen, or by using a method of detecting a movement even when the touch is not directly made. When the touch screen is used in a non-contact manner, a method of detecting a movement using a sensor is mainly used.

Meanwhile, the present invention is characterized by dividing a range A of a predetermined width around the button B into a plurality of drag regions as shown in FIGS. 5 to 6.

When divided into a plurality of drag regions, each of the drag regions having a predetermined width can be monitored to analyze the pattern of the drag. This is because the touch panel only has to pass through each drag area, and there is no particular limitation on the movement within the drag area.

As described above, the present invention divides the touch screen into a plurality of different drag regions on the basis of each button B, analyzes drag patterns formed along the divided drag regions, and generates and displays characters.

Therefore, the selection of each vowel is convenient and easy, and can greatly reduce the selection error. It also accurately analyzes straight lines as well as dragging curves, allowing you to select vowels and master text input without spending a long time.

On the other hand, in the prior art, there is no concept of a drag area divided into a plurality, as in the present invention. Therefore, there is a difficulty in dragging correctly while following a reference line set in a straight line or a diagonal direction. In addition, in order to avoid this problem, a complicated method such as dividing the command according to the number of drags has to be used.

The drag area is divided 11 (hereinafter, referred to as 'first area partition') into different drag areas between the inside and the outside of the button B based on the button B displayed on the keypad as shown in FIG. 5. In addition, it is divided 12 (hereinafter referred to as 'second area division') into different drag regions based on an extension line extending from each side constituting the button B.

Preferably, the drag area may set a range A of a predetermined width around the button B. FIG. In this effective range A, the first area division 11 divides the two drag areas. In addition, the outside of the button B is divided into eight drag regions by the second region division 12. Therefore, as described in detail below, the user can easily input various drag patterns and the terminal accurately analyzes them.

As another example, the position of the drag area may be changed as shown in FIG. 6. This is because when the user does not touch the center point of the button B, it is necessary to reset the drag area around the touch point T_P that is actually touched. Therefore, the user may just drag as usual.

As shown in FIG. 5, when the drag area D is touched to be slightly shifted from the center point of the button B, it is inconvenient if the drag area is still set based on the center point of the button B. FIG. Thus, as shown in FIG. 6, the first region 11 and the second region 12 are reset based on the touch point T_P. That is, it is reset centering on the virtual button B '.

In particular, the second area segment 12 'is changed such that the width between two horizontal extension lines parallel to each other becomes wider as the distance from the virtual button B' is increased. Thus, a relatively wide drag area is provided to suit the characteristics of the human body, which is relatively difficult to move left and right of the finger.

However, in addition to the horizontal extension lines, the width between the vertical extension lines may be set to be wider. In addition, the manner in which the extension line is changed can be further diversified and subdivided according to the characteristics of the human body in addition to being wider. In addition, even when the center point of the button B is correctly touched as shown in FIG. 5, the width of the vertical or horizontal extension lines may be set to be wider.

As another example, in the drag area, the drag area is divided 13 (hereinafter, referred to as 'third area division') around each corner of FIG. 7 and the button B. FIG.

As an example, the edge of the button B is taken as an intersection, and the drag area is divided into an intersection diagonal line 13a centered at the intersection. This creates four drag zones. In FIG. 7, since the upper right corner of the button B is dragged, the drag area is divided based on the corner.

As described above, when the drag area generated by the third area segmentation 13 is used, a variety of commands may be input by distinguishing the case where the drag starts from the corner and the case where the drag area is not.

Hereinafter, the drag area recognition type character input terminal of the present invention for inputting characters by dividing the drag area and analyzing various patterns dragged along the drag area will be described.

As shown in FIG. 8, the drag area recognition type text input terminal according to the present invention includes a touch screen T_S, a drag area divider 10, a drag analysis unit 20, a mapping table 21, a character generator 30, The touch point comparison unit 40 and the keypad information memory 41 are included.

The touch screen T_S is used to input characters in various terminals such as a smart phone. For example, the keypad shown in FIG. 4 is provided through a screen of the touch screen T_S.

The touch screen T_S receives a command through a finger or a touch pen (including a stylus pen). Input methods include various methods such as a method of directly touching the surface of the touch screen T_S and a non-contact method of detecting a movement by a sensor.

The drag area dividing unit 10 divides a range A of a predetermined width around the button B of the touch screen T_S into a plurality of areas. This divides the drag area.

In the present invention, the drag area can be divided freely and variously as long as a plurality of vowels can be input. However, dividing the drag area as shown in FIGS. 5 to 6 may input the vowel more intuitively from the user's point of view.

As described above, the drag region dividing unit 10 performs the first region dividing 11, the second region dividing 12, and the third region dividing 13.

As shown in FIG. 5, the first area division 11 divides the inside and the outside of the button B into different drag areas, and the second area division 12 divides the outside of the button B, but the respective portions of the button B are divided. The extension lines extend from the sides into different drag regions.

Since the button B is usually formed in a quadrangular shape, the inside and the outside of the button B can be distinguished from each other, and the extension line extends left and right and up and down for each side of the button B, respectively. This provides two drag zones separated by inside and outside and eight drag zones separated by outside by extension lines.

In addition, as shown in FIG. 6, the third area segmentation 13 divides each corner portion of the button B into different drag regions with a center point. Preferably, the drag area is divided by a crossing diagonal line 13a having each corner of the button B as an intersection. This provides four drag zones.

In this case, the drag analysis unit 20 distinguishes the case where the drag starts at each corner of the button (B) and the case where the drag does not start at each corner of each button (B), and each of the cases according to the divided cases By analyzing different commands, you get a wider variety of commands. An example of using the button B will be described later.

On the other hand, the drag analysis unit 20 analyzes the user's drag along the drag area, and transmits the analysis result to the character generator 30. In this case, the drag analysis unit 20 may check the collection corresponding to the analysis result by referring to the mapping table 21 and transmit a result to the character generator 30.

The character generator 30 receives a drag analysis result from the drag analyzer 20 to generate and display a character. The character generator 30 may be used as it is basically mounted on the smart phone.

According to such a configuration, the drag region dividing unit 10 divides the drag region around the selected button B, and the character generator 30 divides the consonant and the drag analyzing unit 20 assigned to the selected button B. The syllables are completed by summing the vowels corresponding to the patterns (i.e., dragging) analyzed by).

The touch point comparison unit 40 compares a point where the user actually touches the button B with a finger and the center point of the touched button B. FIG. The position, arrangement, size and center point of each button B refer to the keypad information memory 41 as an example, and the final comparison result is transmitted to the drag area dividing unit 10.

As shown in FIG. 6, when the touch point T_P touching the button B and the center point of the button B do not coincide with each other, the drag area dividing unit 10 includes an imaginary button having the touch point T_P as the center point. B ') to reset the drag area. That is, the position of the drag area is changed so that the touched point is the center point.

At this time, it is preferable that the extension line used for the second area division 12 is set so that the width formed by the two extension lines parallel to each other becomes wider as the distance from the button B increases.

Hereinafter, a server for providing a downloadable application program according to the present invention will be described.

The drag area recognition type character input terminal according to the present invention as described above may be implemented programmatically except for the touch screen T_S, the mapping table 21 and the keypad information memory 41.

That is, the drag area divider 10, the drag analyzer 20, the character generator 30, and the touch point comparator 40 may be installed in the corresponding terminal by executing the program and applied to the smart phone. In this case, it is implemented by downloading and installing an application (also called an "app" or "app").

Accordingly, the server of the present invention is characterized in that when the drag area recognition type character input terminal of the present invention downloads and implements an application program, the server provides the downloadable application program.

Hereinafter, a character input method using a drag area recognition type character input terminal will be described.

As shown in FIG. 9, first, an input is waited for input of a character through a touch screen T_S (S10).

Next, it is checked whether the consonant button B is selected while waiting for input (S20). When a specific button B is touched among the plurality of buttons B provided through the keypad, the controller recognizes that the consonant is input.

Next, if the consonant button (B) is selected, it is determined whether to release (S30). When the release is made, a character consisting of only consonants is generated (S90) and the input is terminated. In recent years, the conversation using only the consonant consonants of each character is useful at this time.

Most preferably, the release method is automatically released when the button B is released. However, after the touch of the button (B), there is no drag during the set waiting time, or a method of releasing by pressing a separate release button may be used.

Next, if there is no release, the vowel to be combined with the consonants of the selected button B is input, and the drag region division S40 is performed to complete the syllable. The drag area divides a range A of a predetermined width around the button B into a plurality of areas, which has been described above.

Next, when the user sets the area variable execution S50, area variable is executed, and the drag area is changed accordingly. That is, as shown in FIG. 6, the point where the button B is touched and the center point of the button B are compared, and when they do not coincide with each other, the drag area is reset around the touched point.

Next, when the drag area is finished, the user analyzes the pattern of the drag performed continuously while pressing the button B (S70).

According to the present invention, since the drag is made along the drag area having a predetermined width, it is easy to use and easy to use from the user's point of view, thereby enabling accurate input even in a shaking car. In addition, the terminal can accurately analyze the drag pattern.

Next, it is detected whether there is an additional drag (S80). If you have additional drags, add the collection by repeating the steps above. The additional drag will be described in detail below with reference to FIG. 10F.

On the other hand, if there is no additional drag, a character is generated (S90). Character generation is to receive the analysis result of the drag analysis step (S70) from the character generation unit 30 to generate and display the character.

The following describes some representative examples of the method for inputting characters according to the present invention.

However, it will be apparent that there are a large number of drag patterns that can input characters through the drag area, and there is no particular limitation on the drag patterns applicable to the present invention.

First, as shown in FIG. 10A, when inputting 'ga', 'ger', 'high', and 'sphere', the button 'B' is selected to select consonants. Then, dragging outward from the inside of the button B while maintaining the touch, the vowels are combined to complete the syllables.

For example, when dragging to the outside of the button B through the right side inside the button B, 'ㅏ' is input. Similarly, when dragging to the outside through the left side, 'ㅓ' is input, and dragging to the outside through the upper side. 'ㅗ' is inputted, and 'TT' is inputted when dragged outward through the lower side.

In this case, the present invention is divided (ie, divided into first regions) into respective different drag regions having a predetermined width. Therefore, not only the drag along the straight line direction as shown in the left side of FIG. 10A, but also the drag along the straight, diagonal and curved directions as shown in the right side of FIG. 10A.

In other words, as indicated by three arrows in the right drawing of FIG. 10A, dragging to the upper portion to input 'high', tilting slightly to the left from the upper portion, and dragging to the right slightly All that is taken is taken as 'ㅗ'. Therefore, it is very convenient from the user's point of view and inputs characters without mistakes.

Next, as shown in FIG. 10B, when inputting 'Ga', 'Off', 'Kyo', 'Gyu', touch the button (B) with 'a' to select consonants. After that, when the touch is kept moving from the inside of the button B to the outside, and then dragged back into the interior, the vowels are combined to complete the syllables.

Compared to FIG. 10A, the stroke of the vowel is added by going out from the inside of the button B and coming back in, and dragging the right side, the left side, the top side, and the bottom side of the button B respectively indicates' ㅑ ',' ㅕ ',' ㅛ ',' ㅠ 'are combined with consonants.

In this case, the present invention recognizes that not only the straight line is dragged along the direction as shown in the left figure of FIG. 10B, but also the dragged along the curved direction as shown in the right figure of FIG. 10B.

When entering text, hold your smartphone with four fingers and palms except your thumb and drag with your thumb. Curved movements are more convenient and natural than linear movements.

Therefore, according to the present invention, such a curved drag can be used, and a curved drag can be correctly input to process text input.

Next, as shown in Figure 10c 'dog', 'crab', 'and', 'guo' when input, touch the button (B) with 'a' to select consonants. Thereafter, in the state of holding the touch, the button B moves outward. In addition, the direction is changed outside the button B (second area division).

The vowel selected according to the direction from the inside of the button B to the outside is the same as in FIG. 10A. Further, when the direction is changed from the outside of the button B to the right area, 'ㅏ' is added and the left side from the outside of the button B is left. 'ㅓ' is added when the direction is changed to the area, and 'ㅣ' is added when the direction is changed from the outside of the button B to the lower area.

For example, in order to input 'and', 'ㅗ' is added by dragging outward from the inside of the 'B' button B to the outside, and the direction is changed from the outside of the button B to the right area. Add 'ㅏ'.

At this time, the present invention, as shown in the left and right drawings of FIG. 10C, respectively, as well as a straight drag as well as a curved drag can be input, thereby enabling convenient character input.

Next, as shown in FIG. 10D, when inputting 'he', 'system', 'rug', and 'arch', a button B with 'a' is selected to select a consonant. Afterwards, the vowels are combined to complete the syllables by dragging while maintaining the touch.

10D is the same method as the combination of FIGS. 10A, 10B, and 10C described above, and thus a detailed description thereof will be omitted.

Next, FIGS. 10E and 10F divide a drag region (third region division) based on each corner of the button B, and select different collections and additional functions according to the user's dragging.

FIG. 10E illustrates a case where the drag does not start at the corner of the button B, and FIG. 10F illustrates a case where the drag starts at the corner of the button B. FIG.

If it does not start at the corner of the button (B) as shown in Figure 10e is used to add a vowel to the consonants of the button (B) currently touched as an example.

For example, in the case of inputting 'he' and 'gi', the consonant is selected by touching a button B having 'a'. Thereafter, the direction is changed after passing through the corner portion of the button B while keeping the touch. If you move horizontally to the right after passing through the corner, 'ㅡ' is combined, and if you move vertically downward after passing through the corner, 'l' is combined.

On the other hand, starting from the corner of the button (B) as shown in FIG. 10F, for example, it is used to combine vowels with previously selected consonants or to select additional functions such as changing between Korean and English keys.

For example, if the drag moves horizontally to the right, starting at the corner part, 'ㅡ' is additionally combined to a specific selected bar, and if the drag starts vertically to the bottom side, 'l' is additionally combined. .

In addition, when the drag is moved vertically upward starting from the corner portion, an additional function of changing the keypad from the Korean key to the English key is executed. In the case of the English key, since several alphabets are provided in one button B, the English key is input again by dragging.

For example, one button B has three alphabets, such as 'abc'. At this time, simply touching the button B selects the 'b' in the center, and touches the button B to the left. Dragging selects 'a' on the left, while dragging right selects 'c' on the right.

As described above, the present invention divides the drag area so that various functions can be correctly and conveniently input.

The specific embodiments of the present invention have been described above. It is to be understood, however, that the scope and spirit of the present invention is not limited to these specific embodiments, and that various modifications and changes may be made without departing from the spirit of the present invention. If you have, you will understand.

Therefore, it should be understood that the above-described embodiments are provided so that those skilled in the art can fully understand the scope of the present invention. Therefore, it should be understood that the embodiments are to be considered in all respects as illustrative and not restrictive, The invention is only defined by the scope of the claims.
