Text input device and method using a virtual button of the touch screen or touchpad {Inputting Method And Appartus of Character Using Virtual Button on Touch Screen or Touch Pad}

The present invention relates to a text input device and a method using a virtual button of the touch screen or touch pad, and more particularly, to input a character by touching or dragging a plurality of buttons specified in the area of the touch screen or touch pad. The present invention relates to a text input device using a virtual button of a touch screen or a touch pad and a method thereof.

First, the touch screen according to the present invention is a concept including a general touch screen for input by pressing with a finger and a tablet (Tablet) for pressing or writing with a stylus pen. In addition, the touchpad is a plate-type input device commonly used to act as a mouse in a notebook computer. In general, a touch pad may be input by a finger, but may also be input by a pen or other tool.

In general, various methods are used for text input when the size of the terminal is small, such as a PDA or a mobile phone, and the number of keys of the keypad for data input is small.

In particular, in the case of the PDA, since the size of the display is configured as large as possible within the limited size of the PDA itself, most of the PDA implements data input using a touch screen method using a stylus pen or a finger.

For example, in the case of a mobile terminal including a touch screen PDA, a character in a keyboard shape is displayed on a display in order to input a character, and the character is touched by a finger, a stylus pen, or another tool. The method is widely used. There are also a number of methods called "handwriting recognition", which are input methods that use software to write letters directly into the space designated by a finger, stylus pen, or other tool. In addition, a method called "graffiti" is used for English input, in which a character, a finger, a stylus pen, or other tool, is dragged along a specific path to be input.

On the other hand, the applicant filed on April 25, 2002, the application number 10-2002-0022611 filed "character input system for a mobile terminal and a mobile terminal using the same" has a display and a key module consisting of five keys on the bottom or top A method of inputting a character corresponding thereto by arranging and inputting the key module in combination is introduced.

However, experiments have shown that in the case of inputting characters in the above manner, it takes longer to press different keys separately than to input by dragging keys between touch keys or touch pads. .

Especially for mobile phones, PDAs, tablet computers and kiosks that provide touch screens or touchpads, users who already hold the stylus pen to use other functions than text input can use the stylus pen again for text input. Inserting and pressing an external key module with a finger was considered a hassle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to combine characters in a preset button in a device such as a mobile phone, a PDA, a tablet computer, and the like, which can input data using a touch pad or a touch screen. As you type, touch a finger, stylus pen, or other tool on a virtual button that appears on the display, or a designated area on the external touchpad, apart from your finger-clicking buttons on the external key module to combine the corresponding characters.

 (Example)

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the present invention described above in more detail.

As shown in Figs. 1 and 2, the character input device according to the present invention comprises a button area display unit 28 on which a plurality of button areas 21 to 25 are displayed and a character display unit 29 on which characters to be input are displayed. Display 20 divided display, touch screen 10 capable of continuous coordinate input through touch or drag with coordinate input means, a memory that stores characters corresponding to a combination of button codes output by a plurality of preset button areas (35) A button code made by touching any one area twice from the plurality of preset button areas 21 to 25 of the touch screen 10 corresponding to the plurality of button codes or by touching each of the two areas once Extract the character corresponding to the two combinations from the memory 35 to generate the character and display it on the character display unit 29 of the display, or any From the button area, drag point is moved from the button area to the other button area by dragging to determine the location of the end point where the coordinate input ends, and extracts two button codes corresponding to the coordinate area where the start point and the end point are located. The controller 30 is configured to extract a character corresponding to the character from the memory 35 to generate the character and to display the character on the character display unit 29 of the display.

The plurality of button regions include a center button region 25 disposed at the center, an upper button region 21 disposed above the center button region 25, and a right button disposed at the right side of the center button region 25. An area 22, a lower button area 23 disposed below the center button area 25, and a left button area 24 disposed on the left side of the center button area 25 are formed.

In addition, the T button 26 used as a toggle button, and the enter button 27 that plays the same role as the enter key of the computer keyboard when writing a sentence may be further configured.

Although the T button 26 is illustrated as only one button in FIGS. 2 and 3, in some cases, the T button 26 may be configured as a plurality of buttons.

That is, since the input characters system can input Korean, English, Chinese Pinyin, special characters, symbol letters, numbers, etc. using the button areas 21 to 25, the T button 26 is only one button. To configure this function, toggle between Korean-> special characters and symbol characters-> numbers-> English or Chinese Pinyin, and the current input mode uses a partial area of a predetermined position of the character display unit 29. Mark it.

When one T button 26 is used in the above-described manner, there is a problem of increasing the number of toggles. In some cases, two or three toggle buttons are arranged, and each toggle button has one to three input modes. Can be used by setting.

The buttons including the plurality of button areas as described above may be displayed on the fixed area of the display 20 by the control unit 30 as described above. However, in some cases, the character display unit 29 may be an opaque or semi-transparent layer. It can also be overlaid inside. In this case, when the buttons including the plurality of button regions are presented opaquely, the character display unit 29 is hidden, so that the character display unit may be moved by dragging the position at any time. It can be placed anywhere on the display as it is exposed.

When coordinate data corresponding to each of the button areas configured as described above are input through the touch screen 10, the control unit 30 sets a predetermined center button code, an upper button code, a right button code, a lower button code, and a left button. Generate the button code.

The controller 30 generating each button code in the same manner as described above combines the button codes generated by the touch made in the touch screen 10 in two units, and outputs Korean or English corresponding to Table 1, When the drag is made, the start point and the end point code of the drag are determined by generating the start point code and the end point button code, and a Korean or English character corresponding to the combination of the two codes is output. Enter the same key twice, such as "ㅛ", "ㅑ", "ㅠ", "ㅕ" in Korean, "M", "B", "W", "E", and a space. In the case of combinations, dragging is not possible, so input is done by touching twice.

At this time, if the time spent in the button area corresponding to the second touch or the terminal button code corresponding to the "ㄱ", "ㄷ", "ㅂ", "ㅅ", and "ㅈ" in the Hangul input is greater than or equal to a preset time, The above-mentioned characters originally converted to "ㄲ", "ㄸ", "ㅃ", "ㅆ" and "ㅉ" respectively.

In the English input, if the time remaining in the button area corresponding to the second touch or endpoint button code corresponding to the "T" and "U" is more than a preset time, the above-mentioned sentence is displayed as "Y" and "V", respectively. Convert. However, for Chinese Pinyin input, instead of "V" Prints "

In addition, since the plurality of keys 51 implemented on the keypad 52 illustrated in FIG. 2 play the same role as the plurality of button areas 21 to 27 implemented through the touch screen 10, The same input can be made by directly clicking a plurality of keys 51 on the keypad 52 with the fingers without having to display the button areas 21 to 27 on the display 20.

1 and 2, the touch screen 10 is superimposed on the display 20 by coordinate input means, and a keypad 52 having a plurality of existing keys 51 is provided. Although the case using the PDA 50 has been described as an example, as shown in FIG. 3, the touch pad 57 is used as the coordinate input means and the apparatus 55 with the display 20 is used. It may also be implemented through the button region 56 included on the touch pad 57.

Since the button region 56 is implemented on the touch pad 57, a plurality of buttons including the plurality of button regions 21 to 27 as shown in FIG. 2 are printed or configured, or the touch pad 57 It may be formed by irregularities on the surface of the) or may be displayed in a plurality of colors.

The above process will be described in detail with reference to FIGS. 5 to 7.

In the following description, for the sake of convenience, the touch screen is exemplified. However, the character input is performed in the same manner in the touch pad.

In order to set the button area on the touch screen 10, a plurality of preset button areas 21 to 25 are displayed on the display 20 to which the touch screen 10 is attached (S 1).

At this time, a plurality of button codes are set for the plurality of button areas 21 to 25, respectively (S2). That is, when touching or dragging on the touch screen 10 while viewing the plurality of button areas 21 to 25 displayed on the display 20, the button codes of the up / down / left / right / center of each button area are displayed. It is generated by the controller 30.

In addition, the memory 35 should include a character corresponding to each combination of the button codes.

Waiting for input in the state set as described above (S 3), and when input is started through the touch screen 10 (S 4), the button code of the region where the first touch is made is extracted and extracted. It is determined by the time point button code S_Key (S 5).

At this time, the control unit 30 starts the timer operation using the timer function (S 10).

Then, it is checked whether the touch is in a drag state or a touch off state (S6), and if it is determined that the drag state is input, the button code changed during the drag, that is, the middle button code M_Key, is input (S6). 7).

At this time, if the middle button code M_Key corresponds to the left button code generated by the left area button 24 and the time spent in the area is longer than a predetermined time (for example, 500 ms or more; S 12), The delete function is activated from the cursor position to delete one character from the back (S 14), and the timer is initialized (S 15).

If the point of time button code (S_Key) and the middle button code (M_Key) are different from each other by dragging, it is determined that the button area is changed to initialize the timer count (S 9) and check whether the mouse is dragged again (S 6), and the drag state. If it is determined that the time button code (S_Key) and the middle button code (M_Key) is the same (S 8) to check again whether the drag (S 6).

As a result of checking whether the drag is performed (S6), when it is determined that the drag is completed and the touch is off, the button code at the drag end position is recognized as the end button code E_Key (S20).

At this time, if the start button code (S_Key) and the end button code (E_Key) are the same, "1" is added to the button count to check whether the button count is "2". If the last button count is "2" or if the start button code S_Key and the end button code E_Key are different from each other (S21), and two button counts are generated (S24), the start button code (S_Key) And a character corresponding to the combination of and the end button code E_Key are extracted from the memory 35 and displayed on the character display unit 29 of the display 20 (S 25).

If the input time of the endpoint button code E_Key is greater than or equal to the preset time during the second touch or drag, the original character is converted into another character as previously set (S 25).

That is, in the case of "a", the first touch or viewpoint button code S_Key and the second touch or endpoint button code E_Key are combined into "1" and "2", respectively, and the second touch or the endpoint button If the input time of the code E_Key is more than the preset time, the original "a" character is converted into "ㄲ".

When the output of the character is terminated in the same manner as described above, to proceed to the input standby mode (S 3) step for the input of the next character.

In addition to the Korean and English as described above, the character data includes symbol characters or special characters such as periods, commas, and the like.

In order to input such a symbol character or a special character, the present invention extracts two phonemes that can represent at least each symbol from the Hangul name of each symbol character or special character, and generates two phonemes for each symbol as in the Korean mode. Processed by input in a manner. Of course, this process only works while switching the input mode to special character / symbol character mode.

The Korean names for each symbol and the two phonemes extracted are shown in Table 2.

Finish (dot) ㅁ ㅁ (ㅁ) , Comma ㅅ (ㅋ) M ! feeling N A ? question M ㅇ # Sharp (well) S ㅁ (ㅁ) % percent ㅍ S ^ Hats ㅎ (ㅅ) ㅌ (ㄱ) & AND ㅇ C * star ㅂ (ㅅ) ㄹ (ㅌ) @ Att ㅇ (ㄱ) ㅌ | Orel ㅇ (ㅁ) ㅇ (ㄷ) To Tilda (wave) ㅌ (ㅁ) C (a) ; semicolon S Lol : colon Lol D - Hyphen ㅎ ㅍ - Dash C S _ Under bar ㅇ ㅂ Of Slash S D ′ Quot (quotation) ㅋ (ㄷ) ㅌ (ㅇ)

In Table 2, "first input character" and "second input character" mean "." In the case of the ". (Finish)" symbol and thus represent "ㅁ" and "ㅊ". Extracted as a character, it means to input "ㅁ" and "ㅊ" in the same manner as in the Korean mode.

In the above description, a method of inputting a symbol character using Korean characters has been described. However, even when using an alphabet character, a predetermined character may be assigned to each symbol character and the symbol character may be input through input of the alphabet character. In this case, the first input character is designated as the first character of the symbol name, the second input character is designated as the second character of the symbol name, or selected by selecting a main consonant among the characters following it. For example, the symbol ". (Finish)" is "period" in English, so it is implemented by entering p and e (or r) in special character / symbol character mode.

The English names for each symbol and the two phonemes extracted are shown in Table 3.

On the other hand, in the above description, with the input of Hangul, English, special characters / symbols characters Although the Chinese pinyin inputtable using the ruler has been described, a button composed of the button areas 21 to 25 and 21a to 24a as shown in Fig. 4 should be used for numeric input.

That is, since the original button area is composed of five of the upper / right / lower / left / center button areas 21 to 25, it is not suitable for inputting the numbers 0 to 9. Therefore, in order to input the numbers 0 to 9 smoothly, four button areas are additionally arranged between the upper, right, lower, and left button areas 21 to 24, and the numbers are arranged as shown in FIG.

In the case of arranging numbers as described above, 1, 3, 5, and 7 are disposed in the upper / right / lower / left button regions 21 to 24, respectively, between the upper button region 21 and the right button region 22. 2 buttons 21a are disposed therein, 4 buttons 22a are disposed between the right button region 22 and the lower button region 23, and 6 buttons are disposed between the lower button region 23 and the left button region 24. The buttons 23a are arranged, 8 buttons 24a are arranged between the left button area 24 and the upper button area 21, and 0 and 9 are arranged in the center button area 25.

In the case of the center button area 25, the numbers 0 and 9 are arranged together, but since the number 0 has a higher frequency of use than the number 9, it acts as the number 0 for a touch within a preset time and exceeds the preset time. Is to act as the number 9.

In addition, although numbers are shown in each button area in FIG. 4, in some cases, the user may memorize the numbers arranged at the corresponding positions without displaying anything.

The present invention made as described above is capable of inputting characters with minimal time and effort in a device having a difficult keyboard configuration such as a mobile phone, a PDA, a tablet computer, a kiosk, etc. Provide usability.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the technical field to which the present invention pertains without departing from the spirit of the present invention.
