Description

Keyboard input unit of information equipment {A keypad of an informational terminal}

The present invention relates to a keyboard input unit of an information device, and more particularly, to generate one or more signals according to a position pressed by a single button so that various characters including special characters can be input by one push. It relates to a keyboard input unit.

A general telephone is equipped with a numeric keypad consisting of a total of 12 buttons with numbers 0 to 9 and special symbols '*' and '#' engraved on each button. The numeric keypad input unit is essentially installed in not only a general telephone but also a mobile phone, a PDA, a TV remote control, and the like, and a slightly modified numeric keypad input unit is mounted on the right side of the computer keyboard.

Each button of the numeric keypad input unit mounted on a mobile phone or PDA has a number of alphabetic characters written on it so that each character can be entered by pressing the button as well as the corresponding number. Many types of information devices including computers also need to be miniaturized in order to develop small portable devices. Therefore, input devices of information devices that input information by hand are digital keyboards of mobile phones or PDAs. It will be developed or in a similar form. In the future, when home networking technology is developed to enable two-way broadcasting service through a TV, a numeric keypad input unit capable of inputting English characters as a tool for viewers to input desired information will be essentially mounted on the TV remote controller.

However, through these numeric keyboard input units, many kinds of special symbols that can be input on a computer keyboard cannot be conveniently input. Also, it is inconvenient to input English letters or Korean characters, and the input time is also difficult. This takes a lot. In order to enter Korean or English on a mobile phone, it is necessary to press a button many times. 1 illustrates a configuration of a mobile phone keyboard input unit which is widely used in Korea. In order to input a Korean alphabet or an English character in such a keyboard input unit, it is inconvenient to press a specific button several times. For example, 6634882199210 should be pressed to enter the Korean word patent office. To press 'ㅌ', 'ㅎ' and 'ㅊ', press the 6 button, the 8 button, and the 9 button twice. In addition, in order to input consonants such as 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', and 'ㅉ', the 4 button, the 6 button, the 7 button, the 8 button, and the 9 button must be pressed three times. For example, to enter "Thippipopo", you need to press 666166617772377723. The same hard work should be done when entering English words. For example, to enter "korea", you must press the number button 5566677332, such as pressing the 5 button twice to enter 'k' and the 6 button three times to 'o'. As described above, even when a short word is input, it is inconvenient to press a plurality of buttons, and when the amount of information to be input increases, it can be realized that it is very inconvenient to press a button many times. Therefore, the numeric keyboard input unit is a very uncomfortable alphabetic and Korean alphabet input method for users familiar with the existing computer keyboard. In addition, these characters cannot directly enter special characters.

The present invention has been made in order to solve the above problems, the purpose of the present invention is to be able to input a variety of characters with a single press, but the basic type of the currently used numeric keypad input unit is capable of fast and accurate character input A numerical keyboard input unit of a device is proposed.

Another object of the present invention is to propose a numeric keyboard input unit having the same function as a computer keyboard in an information device.

In addition, in the method of positioning the special character of the present invention, the left, bottom, right part of the 3-way or 4-way button type special characters ~ '! @ $% ^-+ = | ＼? /,. ; : () {} [] <> Is located.

In the present invention, as a preferred embodiment, the button includes any one or more of the keys Shift, Control, Alt, Symbol, Caps Lock, Esc, Space.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 2 is an embodiment of a button according to the present invention, Figure 2 (a) shows a 4-Way button 100 of the present invention and Figure 2 (b) shows a 3-Way button 200 of the present invention It is shown. In the button of FIG. 1, which is a conventional button, one signal may be input to one button. In the present invention, one button is divided into three or four small buttons to input three or four signals as one button. As an example of implementing this, there is a 'T' shaped button as shown in FIG. 2 (a), and four pressing positions indicated by circles are separated in one button. This is called the 4-Way button, and pressing different positions generates different signals. Figure 2 (b) is also a 'T' shaped button, one button is separated into three pressing positions circled (called the 3-Way button), when pressing different positions to each other Another signal is generated.

These two 'T' buttons are buttons corresponding to the existing buttons as shown in the number 4 button of FIG. In the 'T' button of FIG. 2 (a), pressing the center portion 110 of the button generates a number '4' signal, and pressing the left portion 120 generates the English letter 'G' or the Korean alphabet 'a' signal. When pressing the lower portion 140, the letter 'H' or the Hangul alphabet key 'ㅋ' signal is generated, and pressing the right portion 130 generates the letter 'I' or the Hangul alphabetic 'ㄲ' signal. Compared with the existing button, in the new button, you only need to press the button once to generate an alphabetic or Korean alphabet signal, but in the existing button, press the button twice to generate the English letter 'H' or the Korean alphabet key 'ㅋ' signal. You need to press the button three times to generate the English letter 'I' or the Korean alphabet 'ㄲ' signal.

The 'T' button of FIG. 2 (b) is basically the same as the 'T' button of FIG. 2 (a), but there is no central push position, and the right part 220, the left part 230, and the lower part 240 It is possible to generate a signal of the number '4' at any of the three positions marked with. Otherwise, the same signal as that of the 'T' button in Fig. 2A is generated. If the time required for the alphabet and the Korean alphabet is different from the time required for the alphabet, it is easy to distinguish whether to process it as a numeric signal or to process it as an English alphabet or the Korean alphabet when the button is pressed.

Figure 3 is an embodiment of a button according to the present invention, Figure 3 (a) is a + 4-way button 300, Figure 3 (b) is a rhombus 4-way button 400, Figure 3 (c) Is a clover-shaped 4-way button 500, and FIG. 3 (d) shows a rectangular 4-way button 600. As shown in FIG. In the present invention, since the +, rhombus, clover, and rectangular 4-way buttons can be operated in the same way as the T-shape, the description will be omitted and only the method of using the 'T' 4-way button will be described below. . In addition, in the present invention, the operation of the 3-way button may be omitted by slightly modifying the operation of the 4-way button.

In the button according to the present invention, the pressing position is preferably such that a protrusion (not shown) is formed in the vertical direction on the plane. This has the advantage of being clearly distinguished from the pressing position of another adjacent button and also distinguishing from the pressing position of the same button.

The following describes how to input English characters.

If the 'T' button as described above is configured as a number keypad of the phone to input only English letters as shown in FIG. In this keyboard, the letters 'A', 'B', 'C' are connected to the number '1' button. It does not cause confusion for the user. In order to input a space, a space key (indicated by Spc: 760) corresponding to a space bar of a computer keyboard is located at the right side of the # button to facilitate input of a space. This keyboard also allows the '*' button 700 to use the Shift key (indicated by Sft: 720) and Caps Lock key (indicated by Cap: 740), which are special keys used in the existing computer keyboard input unit. Add a new key (marked as Sym: 730). These three buttons can be combined with other buttons to generate more signals. For example, as in the computer keyboard, the English key enters lowercase letters of the alphabet, but if you press the Sft button and enter the English key, the uppercase letters of the alphabet are entered, and the Cap is used to enter only uppercase letters of the alphabet as the toggle key. Sym is used to enter special characters or symbols other than English, Korean, and numbers, which will be explained later. Therefore, in the new keyboard input unit, to generate an English letter signal, the user only needs to press a button once, as in a conventional computer keyboard, and alphabets and small letters can be easily input as in a computer keyboard.

If you configure a number keyboard to input only English letters with the + character button as described above, as shown in Figure 5 (a), if you configure a keyboard to input only English letters with a rhombus button, as shown in Figure 5 (b), only the English letter with a clover-shaped button If the number keypad to be input is configured as shown in Fig. 5 (c), when configuring the number keypad of the telephone to input only English letters with a square button is shown in Fig. 5 (d).

In this new numeric input unit, there may be an inconvenience in that the user presses the letter 'Z' and the part pressing the 'A' close to each other, thereby making the wrong press, as shown in FIGS. 6 (a) and 6 (b). This can be eliminated by avoiding button columns or rows on the same line. That is, since the positions of the buttons which generate the English letters are distributed evenly to the keyboard input unit, an error of pressing the wrong button can be reduced. In FIG. 6 (a) and (b), the columns or rows are arranged side by side, but the columns and the rows are alternately arranged within the scope of the present invention.

The following describes how to input special characters.

There are 32 special characters that can be input in the computer keyboard input method.

Table 1

Special characters (symbols) ~ `! @ # $% ^ *-_ + = | \? / "',.:; () {} [] <>

Among these special characters, the remaining 30 special characters except '*' and '#' in the existing number buttons are distributed to the left, bottom, and top buttons in the number buttons from 0 to 9 as shown in FIG. 7. To input special characters except '*' and '#', press Sym button at the right of '*' button.

Next, a method of displaying the Hangul alphabet on the buttons of the numeric keypad input unit according to the present invention will be described. 8 is an embodiment in which the Hangul alphabet according to the present invention is arranged in the keyboard input unit.

This keyboard input unit adds "Korean / English" button to select Korean alphabet and English letters on the bottom of the '#' button so that Korean alphabet and English letters can be selected and input like the computer keyboard. You can select Korean letters and English letters without typing. This button is a toggle button so that Korean and English can be selected alternately each time the button is pressed.

The alphabet of Hangul by Hangul spelling (No. 88-1) is set to twenty-four as shown in Table 2.

TABLE 2

Jamo Consonants (14) Vowels (10) ㄱ ㄴ ㄷ ㄹㅁ ㅂ ㅋㅋㅋ ㅋㅋㅋ ㅏ ㅑ ㅓ ㅕㅗ ㅛ ㅜ ㅠ ㅡ ㅣ

In addition, the sound that cannot be written by the above letter is written in combination of two or more letters, and the kinds thereof are shown in Table 3.

TABLE 3

Consonants (5) Vowels (11) ㄲ ㄸ ㅃ ㅆ ㅉ ㅐ ㅒ ㅔ ㅖ ㅘ ㅙ ㅚ ㅝ ㅞ ㅚ ㅢ

Fourteen consonants and five consonants (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) out of the twenty-four Korean alphabet are shown in Table 4. The left, bottom, and right buttons of the numbers 4, 5, 6, 7, 8, 9, 0 buttons Connect to

Table 4

Number button location left Down Right side One 2 3 4 A Lol ㄲ 5 N D M 6 C ㅌ ㄸ 7 ㅂ ㅍ ㅃ 8 S ㅎ ㅆ 9 ㅈ H ㅃ 0 ㅇ

The reason for this arrangement is according to the following principles.

(1) Match the order of numbers and the order of Hangul alphabet generally.

(2) The voiced sounds (b, ㄹ, ㅁ, ㅇ) are collected in one place.

(3) It should be arranged considering the frequency of consonants.

(4) Audible or old sounds (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) should be placed in the same position.

(5) Organic or harsh sounds (ㅋ, ㅌ,,) should be placed in the same position.

According to this principle, the most frequent consonants used as initial consonants, 'ㅇ', are placed below the number 0 button, which is the most visible and easy to press. Next, the three consonants of the voiced sound except 'ㅇ' ㄴ ㄹㅁ are placed on the left, bottom, and right of the number 5 button, respectively. In addition, considering the physical-phonetic characteristics of the following Korean consonants [Lef Conchevich, Specialty of Korean Characters as Seen from the World Characters, Special Speech of the Korean Language (Hansol Lee Hyun-bok's Retirement Retirement Paper), pp.255-270, 2000] , The rhyme made by overlapping the basic character and the basic character with one stroke and the double character of the basic character are connected to the same number button, the basic character to the left button, the organic to the bottom button, and the horn to the right button. Connect In addition, the basic notes ㄱㄷ ㅂㅅㅈ are placed on the numbers 4, 6, 7, 8, and 9 in order. Finally, the consonant, which is not yet positioned, is placed at the bottom of the number 8 button. 9 schematically illustrates the arrangement of the Hangul consonants.

The vowels in the Hangul alphabet are connected to buttons 1, 2, and 3. The vowels of the Hangul alphabet are three basic characters (·, ㅡ, ㅣ) devised on the basis of Samjae theory, each modeled after Cheonjiin (天地 人), and all other vowels are made by combining these basic characters. . In order to place the vowel of the Hangul alphabet on the button, 'ㅣ' is connected to the number 1 and 'ㅡ' is connected to the number 3. Here, the corresponding vowel signal is issued even if the left, bottom, and right buttons of the buttons 1 and 3 are pressed. Next, to reduce the number of button presses rather than using the celestial vowel '·' alone, the vowel '·' and '‥' created by overlapping the vowel twice are left and right of the button of the number '2'. To. For other vowels, the vowels 'ㅣ', 'ㅡ' and '·', '‥' are combined to create the vowels as shown in Table 5.

Combination Completed Collection '·' + 'ㅣ' ㅓ '‥' + 'ㅣ' ㅕ 'ㅣ' + '·' ㅏ 'ㅣ' + '‥' ㅑ '·' + 'ㅡ' ㅗ '‥' + 'ㅡ' ㅛ 'ㅡ' + '·' TT 'ㅡ' + '‥' ㅠ

The double vowels 'ㅐ', 'ㅒ', 'ㅔ', 'ㅖ', etc. are made by combining the completed vowels with the vowels 'ㅣ' and 'ㅡ'. 10 illustrates a numeric keypad input unit which can be used by combining the alphabet and the Hangul alphabet described above. By repositioning the keyboard input unit that can use both the Korean alphabet and the English, the columns or rows of the keyboard input unit may not be on the same line in order to easily input each button without mistake. 11 illustrates an example in which both columns and rows are alternately arranged.

As described above, a numeric keyboard input unit capable of inputting all numbers, alphabetical characters, symbols, and Korean alphabets according to the present invention can be configured. An embodiment thereof is illustrated in FIG. 12.

As described above, the keyboard input unit of the information apparatus according to the present invention provides an effect of enabling a quick and accurate character input so that various types of characters can be input with a single press while using the numeric keypad input unit currently used as a basic type.

In addition, the keyboard input unit of the information device according to the present invention provides an effect of inputting various special characters having the same functions as those of a computer keyboard even in the keyboard input of a mobile communication terminal, a TV remote control including a mobile phone and the like.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the embodiments described, but should be defined by equivalents of the utility model registration claims as well as the utility model registration claims described below.
