KR20040059502A - The keyboard for both one hand and two hands - Google Patents

Abstract

PURPOSE: A one/two hands keyboard is provided to make the one/two hands keyboard at a lower manufacturing cost while maintaining a shape of the current keyboard, make a user perform input with one hand by installing an extended input key to the current computer set, and reduce key strokes. CONSTITUTION: An additional alphabet key set is added to a numeric keypad. Another key set except alphabets is arranged to the numeric keypad and is selectively used by a character input mode toggle key(3), which is a number lock key. The numeric keypad is changed to a numeric input mode or a character input mode depending on the closing/opening of the number lock key.

Description

The keyboard for both one hand and two hands}

The present invention relates to a computer keyboard, and in particular, can be used as a one-handed keyboard while following the structure of a general keyboard. As a conventional invention, about 10-2001-0018637 (a one-hand keyboard, a key recognition method and a Hangul key recognition method on the keyboard, April 09, 2001) is disclosed, and a conventional keyboard is divided in half. It consists of two keyboards, each of which has a half keyboard that allows you to enter characters from the other half keyboard, so you can use the entire keyboard for both hands or the half keyboard for one hand, depending on the situation.

Since the keyboard does not follow a conventional generalized keyboard, a lot of manufacturing costs are required, and a conventional keyboard cannot be used as it is, so that only a person who purchases a new keyboard can be used, and the present invention aims to improve this.

1 is a general computer keyboard.

In order to achieve the object of the present invention, the calculator keypad 1 provided on the right side of the keyboard is used as a one-handed keypad part. This is because a separate direction dedicated key (2) is formed next to the calculator keypad (1), and the calculator keypad (1) is rarely used as a direction key, so when the number fixing key (3) is released, the character is converted to the direction key. To switch to the key. Thus, when the numeric fixing key 3 is locked, it operates as a calculator key as in the prior art, and when the numeric fixing key 3 is released, characters can be input in the same way as inputting characters on a small keyboard of a mobile phone.

This usually includes a one-handed key input processing unit in an input program program (hereinafter referred to as an input unit) that processes character input in a computer, and the key inputs of the one-handed keypad unit inputted while the numeric fixing key 3 is released are the one-handed key input processing. It is sufficient to have the additional processing process the character input according to each key input. Since the one-handed key input processing unit processes texts is already generalized in a mobile phone, a detailed description thereof will be omitted.

In addition, in order to be able to use the one-handed keyboard according to the present invention without replacing the hardware in the existing computer, it is possible by installing an extended input device including a step of processing a one-handed key input. Since the technology of the extended input device is already generalized, such as the second foreign language input, the detailed description thereof will be omitted. If you want to install and use only this typewriter, it is more convenient to use it by covering the keys with engraved letters arranged on each key.

Hereinafter, the character arrangement of the one-hand keypad unit will be described with reference to the drawings.

2 is an exemplary view of a one-hand keypad unit according to the present invention.

As can be seen in the figure, the numeric fixing key 3 and the enter key 7 have the same input value even when the one-handed key is input. Next, the 0 key 5 becomes a space key, and in the case of a person who inputs with his right hand, it is conveniently located with a thumb. Then, the dot (.) Key 6 is inputted as a dot when pressed once, a comma when pressed twice, and an apostrophe when pressed three times. This is to make it easier to input the punctuation and frequently used symbols directly in English spells when entering with one hand without having to move a lot of hands.

If you first describe the array,

Figure 3 is an illustration of an English arrangement according to the present invention.

Since 26 letters are arranged in 13 keys except for the numeric fixing key 3, the space key 5, the dot key 6, and the enter key 7, two alphabets can be arranged in each key. In the example of FIG. 3, the main principle is to arrange the alphabets one by one in alphabetical order one by one. As an exception, the alphabetical order is used so that T or R, which is one of the most frequently used characters, is input by one key input. You can see some modifications.

If the characters to be entered in succession are arranged on the same key, the character to be input is determined by using the right arrow key 4 before inputting the next character, and the next character is input.

The advantage of this arrangement is that all vowels are entered in one stroke, and are arranged in alphabetical order so that even first-time users can easily find the keys they want to enter.

The following is an explanation of Hangul array.

The Hangul arrangement shown in the example of FIG. 4A is an example of using the remaining 14 keys except for the numeric fixing key 3, the space key 5, and the enter key 7 as the Hangul input keys.

The basic consonants of Hangul consonants 10 consonants, excluding ??, ??, ??, ??, are arranged on each of the 10 keys. Then arrange the vowels, ??, ??, ??, ??, respectively, after their basic characters: ??, ??, ??, ??. And the horns ??, ,, ,, ,, ?? are arranged after the basic 자리, 그, ,, ,, ,, ??. If there are both vowels and horns after the basics such as ??, ??, ??, ??, they should be arranged in the order of basic-vowel-horn. That is, in the example of FIG. 2, ?? is pressed once, ?? is pressed twice, ?? is pressed three times, ?? is input.

The vowel arrays are the default vowels: ??, ,, ,, ,, ,, ,, ,, ,, ?? The four most frequently used vowels, ??, ??, ??, ??, are arranged in front of each of the remaining four keys after the consonants, and the next most frequently used ??, ?? ??Wow ?? Arrange behind. The postscript characters ??, ??, ??, ?? are arranged after their basic characters ??, ??, ??, ??. For example, pressing the ?? key once enters ??, twice pressing ??, and entering the ?? three times ??.

The compound consonants or compound consonants are combined by pressing the letters in sequence.

A feature of the arrangement of each key is that the vowel key is placed in the center so that the hand is moved as little as possible during character input.

4B is an example in which the Hangul alphabet is arranged in 13 keys so that the dot key 6 can be used in the Hangul mode. The consonants are arranged in 10 like the arrangement of FIG. 4A, and the vowels are arranged in 3 keys instead. Vowel array is a very efficient array for inputting vowels with only 3 keys. In detail, the vowel key with (??, ??) is arranged, the negative with (??, ??) is arranged. The vowel key and (??, ??) are divided into an array of neutral vowel keys. The input rules are the basic characters ??, ??, ??, ??, ??, ?? as consonant inputs. According to the order, the first letter is pressed once, the last letter is pressed twice, and the compound string is entered in sequence. The leading vowels ??, ??, ??, ?? are entered in alphabetical order. For example, ?? is ?? + ??, ?? is ?? + ??, ?? is ?? + ??, ?? is ?? + ??.

The advantage of this arrangement is that it is easy to input punctuation marks such as dots and commas, and the vowel and voice vowels are not combined together according to the Hangul vowel rules. Matching vowels, or matching neutral vowels, like ??, ??, ??, ??, ?? As with positive + neutral or negative + neutral, it means that your finger moves as short as possible when you enter a vowel.

As can be seen from the above description, the present invention has the effect of being able to manufacture a two-handed and one-handed keyboard at a low cost while maintaining the conventional keyboard shape, and by installing only an extended input device in the existing computer set, the one-handed keypad There is an effect that allows you to use, an effect of having fewer input strokes, and an effect of easily finding a key to be pressed.
