Abstract

The present invention relates to an input device of a computer, and more particularly to an input device of a mobile device.
The input device for a mobile device has a disadvantage in that the key board needs to be watched for input because the key board is small because it should be miniaturized.
In order to eliminate such inconveniences, a small number of keyboards suitable for the number of fingers is provided to provide an input device that can be conveniently input using intuition.
To this end, in the case of English, a specific rule for the capitalization of the uppercase letters of the alphabet is found, decomposed and recombined.
In the case of the Korean keyboard, the consonants are composed of a combination of the broken down rule and the rule, like the alphabet, and the vowels are composed of three types: “ㅏ, ㅓ”, “ㅗ, TT”, and “ㅡ, ㅣ”. Are assigned to one key and then combined.
Therefore, in the case of using the input device according to the present invention, accurate characters can be input without losing sight to the terminal, and since the number of keys is small, it can be installed at any position of the mobile device and furthermore, the input device attached to a car handle or a glove. Can be implemented.

Description

Keyboard for five fingers {keyboard for five fingers}

It relates to an input terminal of a computer mobile and other electronic devices.

QWERTY keyboard or 2 beol Hangul keyboard is the standard keyboard of the computer, and in mobile devices, keyboards using numeric keys or miniature QWERTY or Hangul 2 beol keyboard are used as standard keyboards.

In mobile devices with a touch screen, several types of keyboards can be simultaneously implemented by software. However, since a key button is small due to the characteristics of a mobile device that emphasizes portability, input by one finger is based.

The keyboard that can be input by one hand is developed and distributed by several companies. Among them, the keyboard which drastically reduced the number of keys is a 4-key keyboard released as a kee4 product from citta.com.

In the case of Hangul keyboard, the syllable structure of the Hangul is divided into the primary neutral finality, and in particular, the vowel is used as the neutral, so the boundary between the initial and the neutral of one syllable is based on the vowel, but in the case of two consecutive syllables Since the consonants of both the syllable and the next syllable are consonants, it is necessary to distinguish consecutive consonants.

In the case of vowels, the so-called 'Cheonji factor' or 'Naratgle' is developed by inputting with a small number of keys. In addition, the combination of vertical strokes and horizontal strokes is used to complete the phoneme. In Naragle, short vowels are placed on several keys, and the double vowels or middle vowels are completed through the stroke additional function keys and continuous input.

Recently, various functions are provided through touch input in mobile devices, and even handwriting recognition is implemented, but in any case, there is a disadvantage in that the input must be performed by visually confirming the position of the key. Has reduced the number of keys, but still has a burdensome size for mobile use, and the four-key keyboard named kee4 has reduced the number of keys clearly, but the combination of keys is not intuitive and it is inconvenient to memorize key values separately. Therefore, by supplementing this, we want to provide a keyboard that anyone can easily input with intuitive key configuration while matching keys and fingers through five keyboards.

With only five keys (additional conversion keys such as Korean and English, uppercase and lowercase letters), you can enter several characters including Korean alphabet, English alphabet and special symbols using five fingers. -), Vertical stroke (|), human stroke (ㅅ) and original stroke (ㅇ), three types of “ㅏ, ㅓ” series, “ㅗ, TT” series, and “ㅡ, ㅣ” series that do not overlap Assign them to one key and combine them.

In the case of English keyboard, each letter is completed by combining horizontal stroke {-}, vertical stroke {|}, semicircle {{}, vstroke {v}, but the combination of half stroke and vstroke is rotated freely. It is implemented by additionally equipped with a function key to distinguish the alphabet.

While using a mobile device, the touch screen can be used as a device that can be input as a keyboard attached to the rear or side of the mobile without allocating a space for a character keyboard on a touch screen or installing a physical keyboard in a predetermined space.

In addition, it can be used as a blind keyboard that can be input without seeing it, or it can be used as an input tool by attaching it to the keyboard glove of a computer to be worn, as well as being attached to a steering wheel to input text while driving, and to carry it while carrying it in a pocket. In addition, it can be used as an input tool attached to an external device such as an earphone.

Description of the embodiment through Figure 1 for the Hangul keyboard.

A simple structure keyboard having a function key + four keys. The 0 key 101 is a function key, the first key 102 has a horizontal stroke ('-'), and the second key 103 has a vertical stroke ('ㅣ'). The third key 104 is composed of an original stroke ('ㅇ'), and the fourth key 105 is composed of a human stroke.

The position of each stroke can be arranged in a convenient position, which can be configured by changing the position of the horizontal stroke and the vertical stroke, but the key values (ㅡ, ㅣ, ㅇ, ㅅ) are fixed and the values of each stroke are arranged as they are in the consonant. In the case of successive syllables, when the last and last characters appear consecutively, the function keys (101) are inputted to distinguish the phonemes. The vowel is input while the 'ㅅ' key is pressed. The first key (ㅏㅓ) is' ㅏ, ㅑ, ㅓ, ㅕ, ', the second key is' ㅗ, ㅛ, TT, ㅠ' and the third key is selected by counting the number of times the 'ㅡ, ㅣ, ㅢ' was pressed. Combine to complete.

Function key can be used as both space key and function key.In this case, press the space key once to separate the phonemes, and press twice to enter one space. I can do it in a state.

All vowels are assumed to be entered while pressing the (g) key, and x3 means three consecutive presses. . A (ㅏ) x 1 ㅑ (ㅏ) x 2 ㅓ (ㅏ) x 3 ㅕ (ㅏ) x 4 ㅗ (ㅗ) x 1 ㅛ (ㅗ) x 2 ㅜ (ㅗ) x 3 ㅠ (ㅗ) x 4 ㅡ (ㅡ) x 1 ㅣ (ㅡ) x 2 ㅢ (ㅡ) x 3 ㅐ (ㅏ) x 1 + (ㅡ) x 2 In the case of double vowels, keep pressing without releasing function key (105) ㅔ (ㅏ) x 3 + (ㅡ) x 2 ㅒ (ㅏ) x 2 + (ㅡ) x 2 ㅖ (ㅏ) x 4 + (ㅡ) x 2 ㅟ (ㅗ) x (ㅡ) x 2 ㅚ (ㅗ) x 1 + (ㅡ) x 2 ㅝ (ㅗ) x 3 + (ㅏ) x 2 ㅘ (ㅗ) x 1 + (ㅏ) x 1

In the case of vowels, while pressing “ㅅ” in the [Fig. 1] key, tapping “ㅡ” once, “ㅏ”, tapping twice, “ㅑ”, tapping three times, “ㅓ”, tapping four times, “ㅕ” And press “ㅣ” key once while pressing “ㅅ”, print “ㅗ” when tapping twice, “ㅛ” when tapping twice, “TT” when tapping three times, “ㅠ” when tapping four times, and press “ㅅ” If you tap “ㅇ” once in the state, “ㅡ” will be printed twice. “ㅣ” will be printed. If you tap three times, “ㅢ” will be displayed.

In the case of double vowels, the above key combinations can be combined together. For example, to output “를”, you can combine the “ㅣ” key once by tapping the “ㅡ” key once and the “ㅇ” key twice. .

In the case of vowel, you can input the combination of the existing developed technology Cheonji-factor keyboard while pressing the 'ㅅ' keyboard. In this case, unlike the assignment of a separate keyboard from the consonant in the keyboard, 'vo' After the assignment, the strokes pressed while the function key is pressed are combined and assigned to the vowel value, so the vowel and the consonant have the same keyboard.

If you look at the structure of Hangul, it is a neutrino jongseong, which is a vowel, and if you capture a situation where a certain key value is entered while the 'ㅅ' keyboard is pressed, the vowel input is confirmed.

In the case of consonants, it is difficult to check which consonants are when the finality is input and subsequent consonants are inputted consecutively. In order to distinguish it, input of a delimiter (confirmation key) is required, which can be distinguished by a function key (combination of space).

That is, the completion of one consonant input is regarded as a consonant input when the subsequent input value is a vowel, and the consonant is distinguished by a function key when the consonant and the consonant are followed. When three consonants separated by function keys are input consecutively, the first two consonants are recognized as the final consonants of the final consonants, and the subsequent consonants are the first consonants of the later syllables.

In the case of double consonants, the value continuously pressed is classified as pressing the function key while releasing the last key and then releasing the last key, or if there is a certain time delay while pressing the last key, it is recognized as a twin consonant.

When the key event is confirmed, the key input is recognized as completed when the key is pressed and released. Therefore, when the vowel is input, the input sequence of all the keys entered while pressing the 'ㅅ' key is 's' When the key is turned off, it is completed as a vowel, and in the case of a pair of consonants, the key input is not terminated when the last key of the input key is pressed, and the pair is released when the last key is turned off after the function key is pressed simultaneously. Consonants are entered or a pair of consonants are input after a certain time. Since the above-described key value input method is input through a computer or the like, the key value input method is implemented using a storage device or a computing device such as a computer. In order to perform operation by receiving key value from the device, the device driver is installed in the computer in advance, and the program includes a database that can map a certain key value array and the ASCII code or Unicode value corresponding to the array. Consecutive key value input is divided into a group of key values through a certain operation. This is called a unit array, and this unit array is compared with the key value array in the database and returned as ASCII code or Unicode. Or to generate an English alphabet. In the present invention, a key In order to separate and recognize the array of s, the following three methods are used in combination, and these values are calculated to generate Unicode for key values. The first method is to generate Unicode for consonants. When the combination of four stroke keys is entered in order, the input data is stored in sequence, and when the function keys are tapped off, the combination of the stroke keys input through the operation unit is divided into a unit array for coding into one Unicode. After that, it finds a value that matches the value of [Table 1] previously stored in the database and temporarily stores the Unicode of the consonant. The second method is to generate the Unicode of the double consonant. Tap the function key (101) and turn off the last key when the last key combination of a, “c”, “ㅂ”, “ㅅ”, and “ㅈ” keys is not off. This function temporarily stores the Unicode corresponding to the consonants “ㄲ”, ”ㄸ”, ”ㅃ”, ”ㅆ”, ”ㅉ”. The third method uses the function keys to generate Unicode for the vowels. If you press 105 key and just release it to use the phoneme of “ㅅ”, you can tap 101 key while pressing 105 key. Unicode is generated, but when 105 key is pressed and tapping combination of 102, 103,104 key and 105 key is off, the combination of 102,103,104 key input while 105 key is pressed is stored as the value shown in [Table 2]. The unicode values of the vowel values corresponding to the same combination are temporarily stored in comparison with the database values. As described above, the input of Hangul syllables is completed by the combination rule of the bolbe type keyboard according to the order of the Unicode values of the temporarily stored consonants.

In the keyboard according to the present invention, it is possible to perform a character input by using a function key up to enter key, number, direction key and alphabet as well as special characters.

In Korean mode or English mode, the key value of special characters, numbers, and function keys is input while maintaining the same. The mode selection switch can be configured separately.

An embodiment of a 5-key keyboard for English input can be seen through FIG.

Space and function keys 201 are 'a', horizontal stroke key 202 is 'b', vertical stroke key 203 is 'c', semi-stroke key 204 is 'd' and v stroke key 205 ) Is assigned a key value as 'e', and the composition of the combination for each alphabet is created based on the contents of FIG. 3 and is shown in Table 2 below.

-K and P are assumed to have two vertical strokes (K, P).
Or, if the stroke is in the middle of the first vertical stroke, enter the vertical stroke twice. (B, E, F, H, KP, R,)
-Radial symmetric characters like O and X add one more stroke to distinguish from other alphabets. The tail of Q is either horizontal or vertical, and the tail of R is also vertical or horizontal.

Combination of the above is made by disassembling the capital letters of the English alphabet and can be judged intuitively based on the shape and stroke order of strokes without any memorization process.

Special characters can also be entered using the function keys. This is done by pressing a certain key value while pressing the function key.

The above special codes are assigned to horizontal stroke keys for horizontal stroke keys, vertical stroke keys for vertical stroke keys, curved stroke letters to semi-circle stroke keys, and curved keys to v stroke keys to enhance intuition. , Del, Backspace and Arrow keys are created with a combination of all key presses.

101 (Function key): Used to input phonemes, special character keys and function keys.
102 (first key): A key for inputting a horizontal stroke among consonant elements of a consonant as a horizontal stroke, and corresponds to a horizontal stroke of the vowel.
In addition, when the fourth key, which is the second function key F, is pressed once, it is recognized as a horizontal stroke of the vowel and combined with another stroke to form a consonant combination element.
103 (Second key): When input independently, it is recognized as a consonant's vertical stroke element, but when it is pressed while the function key (F) is pressed, it is recognized as a vertical stroke of the vowel and used as an element of vowel combination. .
104 (third key): It is recognized as the consonant 'ㅇ' key, but when the function key (F) is pressed, it is recognized as a vertical or horizontal break (·) of the vowel.
105 (4th key): If there is a simple tapping input, it is recognized as 'ㅅ' of consonant, but it is functioned as a function key (F).
201 <a>: Function and space keys used to separate letters, enter spaces, and enter other control keys.
202 <b>: As the stroke key, it is used as the stroke of A, E, F, G, H, L, T, Z and the tail stroke of Q.
203 <c>: Vertical stroke key, widely used for B, D, E, F, G, H, I, J, K, L, M, N, P, R, T, U, Y, K, P In the alphabet after K, such as, R, if it intersects with other line segments in the middle of the vertical stroke, input one vertical stroke twice to form one vertical stroke.
204 <d>: As a semi-circle key, wherever there is a round in B, C, D, G, J, O, P, Q, R, S, U, enter this key regardless of the position of the semicircle opening. A complete circle looks like a semicircle of two overlapping, but for the distinction between 'O' and 'S', 'O' is entered more once in a feeling that it is a more complete circle.
205 <d>: This is the stroke key, whether A or K, M, N, V, W, X, Y, or Z, regardless of opening direction or symmetry. In the case of M, N, and Z, the v stroke is input after the vertical stroke or the horizontal stroke is input.
