KR20040106916A - Miniaturized Keyboard Using Symmetrical Nervous Response of Fingers of Both Hands - Google Patents

Abstract

PURPOSE: A small sized keyboard for one hand is provided to reduce the size of a conventional keyboard for both the hands into the size for one hand while practically maintaining the arrangement of the keys in a conventional keyboard by symmetrically overlapping left hand side keys with right hand side keys of the conventional keyboard. CONSTITUTION: The device comprises general keys and a toggle key(22). The general keys are arranged by symmetrically overlapping left hand side keys with right hand side keys in the conventional keyboard. The toggle key(22), if pushed, enables a user to input vowels and consonants arranged in conventional left hand keys, but if not pushed, to input vowels and consonants arranged in conventional right hand keys.

Description

Miniaturized Keyboard Using Symmetrical Nervous Response of Fingers of Both Hands}

Conventional keyboards are used as the main input means for characters in computers, and each character to be input is assigned a corresponding button, so it is possible to input characters quickly without looking at the seat, but because of the large number of buttons, a large area is required. It is not suitable for use in an environment such as a communication device or a portable keyboard, and there is a small keypad as a character input means other than the existing keyboard, but the number of character buttons is small and each character does not have a corresponding button. Of course, there is a disadvantage of long input time.

Recently, an external keypad made of rubber material, which is rolled up like a newspaper, is used to realize a convenient document working environment in small information devices, etc. There is a downside to dullness.

Therefore, if the keyboard can be miniaturized while being able to input characters relatively quickly like a conventional keyboard, that is, when an input tool having a characteristic between the conventional keyboard and the keypad is enabled, it can be used for portable and small information communication devices. It is more convenient to use.

According to the present invention, a keyboard having a large size can be easily miniaturized using a symmetric neural motion response of both fingers while maintaining a conventional character button arrangement, so that it is possible to easily input a letter with a relatively high speed even with one hand. As well as to enable the input of characters without looking at the keyboard, the purpose is to enable convenient use in a variety of devices in the field of portable and small information and communication.

According to the present invention for achieving the above object, the small keyboard using the symmetrical neuronal motion response of the two-handed fingers of the left and right hand using the phenomenon that the fingers of the right hand and the left hand symmetrically exhibit the same neurological motion response It is characterized in that the miniaturization is possible by removing one part after the keyboard buttons are symmetrically overlapped.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows the appearance of a general conventional keyboard 10. To use this, as shown in FIG. 2, the left side of the keyboard places a finger of the left hand, and the right button puts a finger of the right hand on b. When you press a letter on the line up to e, you use the corresponding finger to enter the letter.

When entering letters, each finger of the left and right hand is symmetrical by the nervous system, so when it is necessary to press the thumb of the left hand, the thumb of the right hand is used, the index finger of the left hand is the index finger of the right hand, and the index finger of the left hand is the right hand. It is easy to press the opposite finger symmetrically, such as the forefinger of. For example, when the index finger of the left hand is pressed, it is easy to move the index finger of the right hand. The simultaneous reaction is difficult and difficult to move instead.

Using this characteristic, as shown in FIG. 3, it is possible to overlap the right side of the keyboard used by the right hand and the left part of the keyboard used by the left hand, and reduce the keyboard in half. By placing the letter button so that the right finger d having the same response can be inputted, the entire character can be input using the symmetry of the letter with only one hand.

4 shows an example of a small right handed English keyboard 20 constructed by the above method, for example, to input PEN, P presses Q / P by the right finger e, and E is the original c on the left side of the left plate. Since it is located in the row, press E / I with the right hand c, and then press the Toggle button (22). Finally, N can enter PEN by pressing B / N with the right finger b, where the Toggle button ( 22) is displayed by changing the character located on the left hand side of the existing keyboard among the two characters displayed on the key button.

Using the above method, as shown in FIG. 5, a small Hangul keyboard 25 can be configured, and the input method of Hangul first indicates an end of a character at the end of one letter composed of initial, neutral, and final characters. By default, the program recognizes the first button pressed on the keyboard as a consonant, the second button as a vowel, and the third button as a consonant to represent the consonant. Toggle (22) is displayed after the vowel button recognized as a vowel in the consonant. In the last case, the consonant comes when it is a final consonant, but when it is double consonant, To be recognized as a possible input of the characters, and described above, it can be summarized as follows:

Consonant: Consonant: Consonant + Consonant + Toggle

Ex) ㄱ ㄴ ... ㅎ (ㄲ ㄸ ㅃ ㅆ ㅉ)

Neutral: Vowel (Diagrams: Vowel + Vowel + Toggle):

Ex) ㅏ ㅑ ... ㅜ ㅣ (ㅘ ㅙ ㅚ ㅝ. ..)

Jongsung: Consonant (Double Consonant: Consonant + Consonant) + End:

Ex) ㄱ ㄴ ... ㅎ (ㄲ ㄳ ㄵ ㄶ ㄺ ㅄ ..)

For example, the 'KIPO' can be entered with the keys ㅌ-ㄱ @ ㅎ ㅓ @ ㅊ ㅇ @. Also, in the case of 'what is the land', the Toggle ㅇ ㅇ @ ㅇ ㅣ @ ㅇ ㅜ You can input with ㅁ 입력 ㄹ @, where @ represents End button 28 and the Shift key is not used.

The flowchart of the operation program for the small English keyboard 20 using the symmetric neural motion response of the two-handed fingers according to the present invention first initializes flags associated with the keyboard as shown in FIG. 6 (S30) and changes in input of the keyboard. Check (S31) to store the scan code of the pressed button (S32).

If the pressed button is not a Toggle key (S33) and is a double-character button (S34), a double-letter flag is set to indicate that the pressed button is a button capable of displaying characters twice (S35). Select the code as a scan code (S36), if not a double-character button, just proceed to the next step.

If the pressed button is the Toggle key (S33), check whether the double character flag is set (S37), and then send the scan code of the Back Space character to remove the transmitted character immediately (S38). The left hand selects a scan code of an inputtable character as a scan code (S39) and resets the double character flag (S40), and then transmits the value of the scan code determined in the above process to an external system (S41).

The flowchart of the operation program for the small Hangul keyboard 25 using the symmetric neural motion response of the two-handed fingers in accordance with the present invention can be configured according to the above-described method as well, by changing the operation mode of both the Korean and English keyboards. The keyboard can be configured to be used by the left hand or the right hand.

As described above, according to the present invention, when the left and right portions of the keyboard are overlapped with each other by using the symmetrical neural response of the fingers of both hands, the keyboard can be miniaturized and the button layout of the existing keyboard is practically maintained. In this state, it is possible to input characters with relatively high speed with only one hand, and it can be used by switching to the right or left hand keyboard, which is convenient for portable and small information communication devices as the input tool for the middle area of the existing keyboard and keypad. It is possible to use.
