Description

Korean input method using a limited number of key means and a computer input device {a method for inputting the Korean letters with limited number of key means, and a input unit in a computer}

The present invention relates to a method for inputting Hangul using a limited number of key means, and another invention relates to an input device of a computer equipped with a limited number of key means to a mouse.

There are a number of ways in which Korean characters can be input using a limited number of key means, such as a small number of key buttons. Looking at this by type, the first method is to implement all the letters of the Hangul, namely, terminal consonants, double consonants, Bokja consonants, short vowels, and the vowels assigned to each key means. In this method, almost all Hangul is implemented, but as many as 10 letters are assigned to one key means, the number of touches of the key means is complicated, and the key means for terminating a character must be touched every letter.

In the second method, only some of the Hangul characters are assigned to the key means, but the unassigned characters are implemented by a combination of the key means. This method is useful because the input method is similar to that of a conventional keyboard, but special key means are required to implement all Hangul characters.

The third method is to find a string that can be expressed from input characters by databaseting the string of Korean characters. This method is possible to input Hangul with relatively few touches of key means. It is not suitable as a general Hangul input method because it cannot input strings that are not in the database and requires additional devices such as memory.

However, each of these input methods is implemented by a unique method, which is different from the standard English input method. The Korean input method and the English input method should be similar to the user's convenience, and the production of a program for the implementation becomes easy.

Meanwhile, a keyboard and a mouse are the most typical input devices of a conventional computer. A mouse is used to operate a screen and a keyboard is used to input characters. However, when entering a user ID (ID) or a simple search word on the Internet, it is inconvenient to use the mouse and keyboard alternately.

An object of the present invention is to provide a Hangul input method that is compatible with the English input method and easy to learn while implementing all possible Hangul using a limited number of key means.

Yet another object of the present invention is to provide an input device of a computer which can mount a limited number of key means to a mouse device and perform screen manipulation and text input as one device.

1: key, 6: mouse button,

11, 12, 15: key means for functioning as a switch key means, 16: shift key,

21: mouse cover, 22: position sensing means, 23: control means, 24: transmission means

As described above, all Korean characters and letters should be implemented using a limited number of key means, and should be compatible with the English input method. A brief description of the standard English input method is to assign a character set consisting of up to 26 alphanumeric characters to nine key means. When the same key means is touched continuously, the characters in the character set of the key means are toggled, and are finally input when the other key means is touched. For example, in the case of a key means for inputting ABC, A is displayed at one touch, B is displayed at a second touch, and C is displayed at a third touch. Then, when another key means is touched, the character at that time is inputted decisively. Then, when it is necessary to repeatedly input the same character as in AA, after inputting A, the key means for inputting a space character is confirmed, and then the second A is input.

In summary, about three letters are assigned to one key means, and when one key means is touched, a character is temporarily inputted, and is finally input when a key means different from the key means is touched. No separate keying aid is required except when the same character is repeated. Therefore, Hangul is also preferably implemented by this principle.

Figure 1 shows a set of characters assigned to the key means for implementing the Hangul input method according to an embodiment of the present invention. Character set (ㄱ, ㄲ, ㅋ), (ㄴ, ㄹ), (ㄴ, ㄸ, 하여) based on 음, ㅓ, ㅜ, ,, ㅡ, ㅣ as 한글, ㅓ, 자, ㅡ, ㅣ among 51 Korean characters ), (ㅁ, ㅇ), (ㅂ, ㅃ, ㅍ), (ㅅ, ㅆ, ㅎ), (ㅈ, ㅉ, ㅊ), (ㅏ, ㅓ), (ㅗ, ㅜ, ㅡ), (ㅣ) They are classified and assigned to ten key means, respectively. There are further key means for inputting an undefined purpose and a space character. The method of inputting the basic character is the same as the English input method in the case of a key means assigned a character set including a plurality of characters. For example, in the case of the key means for inputting (ㄱ, ㄲ, ㅋ), ㄱ will be displayed for one touch, ㄲ will be displayed for two touches, and ㅋ will be displayed for three touches. Becomes a again. Then, when another key means is touched, the character at that time is inputted decisively. However, in case of character set (ㅣ), only one character is assigned, so it does not need to be entered in toggle mode.

Unassigned characters are implemented as a combination of base characters. First consonants that are not assigned are the consonants 복, ㄳ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ. To input the Bok consonants without the aid of a separate key means, the consonants a, s, b, and b which constitute the Bok consonants must be assigned to different key means. That is, in the case of ㄻ and ㅁ is in one key means, after entering ㄹ and then touching again, it toggles to ㅁ, so it is not possible to enter ㄻ without the help of a separate key means. On the other hand, the character set of the Hangul consonants is ah ㄱ, ㄲ, ㅋ, 음 ㅇ, ㅎ According to the characteristics of the consonants are generally arranged in the same key means, so that the user is easy to learn.

Also, unassigned vowels include ㅑ, ㅐ, ㅒ, ㅕ, ㅔ, ㅠ, ㅛ, ㅚ, ㅙ, ㅚ, 각각, ㅞ, ㅟ, ㅢ. Each component letter is assigned to a different key.

Character to be combined Construction Character to be combined Construction Character to be combined Construction ㅑ ㅣ, ㅏ ㅛ ㅣ, ㅗ ㅝ TT, ㅓ ㅐ ㅏ, ㅣ ㅠ ㅣ, ㅜ ㅞ ㅜ, ㅓ, ㅣ ㅒ ㅣ, ㅏ, ㅣ ㅘ ㅗ, ㅏ ㅟ TT, ㅣ ㅕ ㅣ, ㅓ ㅙ ㅗ, ㅏ, ㅣ ㅢ ㅡ, ㅣ ㅔ ㅓ, ㅣ ㅚ ㅗ, ㅣ ㅖ ㅣ, ㅓ, ㅣ

However, considering the typos of users,, is a combination of ㅏ, ㅣ, ㅣ, ㅕ is a combination of ㅓ, ㅣ, ㅣ, ㅛ is a combination of ㅗ, ㅣ, ㅣ, ㅠ is TT, ㅣ, ㅣ In combination, it is preferable that ㅒ is a combination of ㅏ, ㅣ, ㅣ, ㅣ and ㅖ is also possible with a combination of ㅓ, ㅣ, ㅣ, ㅣ. The appearance | is repeated, but it is recognized as a different character even if it is input again because | and | are combined.

On the other hand, unlike in English, Hangul automata is required for the combination of letters and the formation of letters because the initial, neutral, and Jongsung must form a single letter. (Details of the Hangul Automata is already known technology, so description is omitted here.) The letters can be formed by the Hangul automata, and no separate key means is required between the letters. However, when characters in the same set are continuously inputted, for example, in the case of "quickly", enter the "r" character of "red" and then touch the space character key means to terminate the character "red" A new letter "L" is formed by typing 'ㄹ "As described above, the same method is used in the English input method.

On the other hand, the character set can be implemented in various forms under the conditions that meet the principle. It is also possible to change the input order of the characters in the character set, to change the position of the key means, in the case of consonants, to change the mutual character set, or to form the character set with ㅁ, ㅇ. Vowel diagrams (ㅏ, ㅓ), (ㅗ, ㅜ), (ㅣ, ㅡ, ㅢ) or (ㅏ, ㅑ, ㅐ, ㅒ) as shown in Figure 2 (ㅓ. ㅕ, ㅔ, ㅖ). You can also use, (ㅗ, TT, ㅛ, ㅠ), (ㅣ, ㅡ, ㅢ). The latter uses eleven key means, but it is easier for the user to learn because the combination of vowels is simple and all the characters entered on a conventional keyboard are assigned.

However, in order to use the present invention as a more complete input means, it should be able to input English letters, numbers, and special characters, which is shown in another embodiment of the present invention described later. However, in order to input characters using the existing word processor according to the present invention, a separate input window is input before the characters are input in the word processor, or inputted in units of characters, or after receiving basic characters or some combination characters. The code can be converted and transmitted properly when it is input decisively so that it can be used in an existing word processor. However, it would be more desirable for a word processor or character input device to include the present invention.

3 and 4 are a perspective view and an exploded front view of the input device of the computer according to another embodiment of the invention, respectively.

The input device is a mouse device having a kind of keyboard function, the mouse base plate 20; A mouse cover 21 attached to the mouse bottom plate 20; A position detecting means 22 mounted on the bottom plate 20 for detecting a movement of the mouse; A mouse button 6 attached to the mouse cover and capable of generating a signal when touched, and a limited number of key means 1; A control means (23) mounted inside the mouse for detecting the position information of the position detecting means (24) and the touch signal of the mouse button (6) and each key means (1); It comprises a transmission means 24 for connecting the control means 23 and the computer to transmit the code generated by the control means 23 to the computer. A typical mouse functions to move the mouse cursor in correspondence with the mouse cursor of the computer monitor and to notify the computer when the user touches a button. As is known, there are a ball mouse and a light mouse according to the position detecting means 22.

A typical mouse has a size enough to be held by a user. Only two or three buttons are provided at the front end of the upper surface of the mouse cover, and no device is attached to the other parts. Here, 12 key means 1 are arranged in 4 rows and 3 columns, and each key means 1 is finger-widthd so that the user can type with one hand, that is, the user can type with the index finger, middle finger, and ring finger. It is about thickness. In addition, since most of the user's middle finger is longer than the other fingers, the middle key means 1 is placed slightly upstream of the front end. In addition, there are two and one key means 11, 12, and 15, which are smaller than the key means 1, in the space before and after the key means 1 in the middle row, respectively, for switching the mode of the apparatus. Used. There are three key means 16 mounted on the left and right sides of the mouse cover 21 so as to be able to touch them with the thumb and the little finger, respectively, which are used as the shift key, the control key, and the alt key. , When touched simultaneously with the key means 1 performs a special function.

The key means (1) can be implemented by a mechanical or membrane method using a rubber cap like the key means of a conventional keyboard, it may be implemented by a micro switch like a button of a mouse. Since the mouse must move, it is preferable to use a lighter microswitch. In addition, the key means 1 is touched when the mouse is grabbed to move. To prevent this, the key means 1 may be implemented with a touch pad, or the cover of the key means 1 may be separately provided. An electrical signal is generated when the key means 1 is touched, which is transmitted to the control means 23.

The control means 23 is implemented by an electronic circuit called a controller. In general, the controller of the mouse codes the position information of the position detection means and the signal of the mouse button, and the controller of the keyboard distinguishes the touched key means by using signals transmitted from a plurality of key means, codes them, and transmits the transmission means. Send the code to the computer body through The control means 23 of the present apparatus may be provided with a mouse controller and a keyboard controller, respectively. However, since the control means 23 has a substantially similar structure, it is more preferable to extend one of them. The transmission means 24 may also be connected to the computer via a cable or wirelessly.

On the other hand, to implement various functions of the keyboard, there are several modes. In order to switch between these modes, the present embodiment has separate key means (11, 12, 15), but can also be implemented in the form of a Korean-English switching window of the window. Switching key means (11, 12, 15) is a mouse / key switch key means 11 for switching between the switch key mouse mode and the keyboard mode above the middle row of the key means 1, and switching between the character input mode and the function mode. For the door / machine switch key means 12 is provided, the Korean / English / male switch key means 15 for switching between the Hangul mode, English mode, number mode is provided. Each of the switching key means 11, 12, 15 switches the mode of the corresponding switching key means 11, 12, 15 each time it touches. The above-described control means may store the state in its own memory and convert the code according to each state and transmit the code to the computer, or notify the computer body of the state so that the computer body manages it.

The mouse mode is implemented when the hemp / key switch key means 11 instructs the mouse mode, in which the key means 1 does not perform any function. On the other hand, the keyboard mode is implemented when the hemp / key switching key means 11 instructs the keyboard mode, in which case the position detecting means 22 of the mouse does not function. In addition, a key mouse mode in which the position detecting means of the keyboard and the mouse function simultaneously can be provided as necessary. In the keyboard mode, there are a character input mode and a function mode which are switched by the door / machine switching key means 12.

5 is a plan view of a computer input apparatus according to another embodiment of the present invention, showing the operation of the key means in the character input mode. In the character input mode, there are Korean mode for inputting Korean, English mode for inputting English, numeric mode for inputting numbers, and special characters for inputting Korean characters which are switched by the Korean / English / Male conversion key means (15). There may be a mode for. There may be various implementation methods for the character input method. The illustrated embodiment is in accordance with the Hangul input method and the standard English input method and the numeric input method according to the above-described embodiment of the present invention. In the Korean mode and the English mode, Korean and English are implemented as described above. In English mode, the * key means at the bottom of the left column switches between uppercase and lowercase English letters. In the numeric mode, the assigned number is input whenever touched in the same way as a normal keyboard. And * key means to select special characters. Although not shown, various special characters are assigned to each key means 1, and when the key means 1 is touched, the assigned special characters are input.

6 is a plan view of a computer input device according to another embodiment of the present invention, showing the operation of the key means in the function mode. The function mode is implemented when the ma / key switch key means 11 instructs the keyboard mode and the door / machine switch key means 12 instructs the function mode. The computer keyboard has a number of function keys, such as arrow keys, PgUp keys, PgDn keys, home keys, End keys, and Tab keys. These may be implemented by assigning them as shown in the figure or by other means. If necessary, the other function keys may also be implemented by switching using the Korean / English / Korean switching key means 15 or the like in a sub mode. .

On the other hand, the button 6 of the mouse to perform the functions of the enter (Enter) key and the backspace (Backspace) key in the keyboard mode, respectively. The three key means 16 provided on the left and right sides of the mouse cover 21 and used as a shift key, a control key, and the alt key, respectively, are used as a means for inputting a second or third character during character input or a program. Used as a shortcut.

As such, although there is a limited number of key means 1, it becomes an input device capable of performing almost any role of the keyboard. Therefore, it is possible to replace the existing keyboard, even if the development of the voice recognition technology to eliminate the need for a keyboard, it will be more useful at this time because an input device for correcting the error is necessary.

Therefore, the present invention can input all the Hangul in almost the same way as the English input method, it is easy for the user to learn and simplify the production of a program for its implementation.

Yet another invention is capable of screen manipulation and text entry with a single device. In particular, it allows you to do most of your computer work with one hand.
