Description

Keyboard for small-sized electronic machines and method for inputting characters by using the same}

The present invention relates to a keyboard for a small electronic device and a character input method using the same. More particularly, the letter is rearranged to a specific rule in each key of the basic reduced keyboard in the form of a 4 × 3 matrix, and a collection or A small electromagnetic field that provides convenience of character input and further improves the character input speed by placing a key (center point key) having a subsequent consonant input function and inputting a character by a combination of the center key or the key of the futa key. The present invention relates to a keyboard and a character input method using the same.

Today, the use of various kinds of small electronic devices, such as mobile phones, PDAs, smart phones, web pads, handheld PCs, etc., is changing slowly, and miniature keyboards are usually used for such small electronic devices.

As the demand for miniaturized keyboards adopted in small electronic devices increases with the increase in the use of small electronic devices, various types of text input methods have been developed. have. Among these, the multiple stroke method is adopted as a basic input method in most languages in the world despite the inconvenience of having a large number of input strokes.

The multi-tapping method is commonly called a multi-tab method, which presses the same button once, twice, three times, ... consecutively so that different characters are outputted according to the number of pressing times. For example, when the English alphabet is input in such a multi-taking manner, the PQRS disposed on the button 7 of the reduced keyboard as shown in FIG. 1 may be different depending on the electronic device manufacturer. If you press the button 7 once, P is input, twice is to enter Q, three times to enter R, and four times to enter S. In other words, if you press button 7 repeatedly, PQRSPQ ... is used to continuously cycle the alphabet.

However, if you want to enter a format in which two different alphabets arranged on button 7 are consecutive (for example, RS), you need to press button 7 four times, and the two letters are not separated by four presses. Occurs. Here, two methods are used to solve the problem, one of which is to input the first letter and then artificially move the cursor to separate the two different letters, and the other is about two seconds after entering the first letter. Wait for a while and when the cursor moves automatically, enter the second letter.

If the number of alphabets is small like English, up to four alphabets are placed on the same button (for example, buttons 7 and 9), so you can bear some strokes to input the characters. In the case of Japanese characters such as Japanese hiragana, when 10 letters are placed on the same button, it is difficult to bear the number of strokes required. If you accidentally press the same button consecutively and miss the target character, you may have to go back one round and return to the target character. In this way, the multi-hit method requires that the characters placed on the same button are not automatically separated, so that the cursor must be operated artificially, and when there are many letters placed on the button, the number of strokes required for input is too large. However, there are a number of problems that currently do not apply universally to all languages.

Meanwhile, the T9 method is a method of inputting a target word by pressing a button on which the corresponding alphabet is placed once from the first letter to the last letter of the word, and this method causes the result value to overlap. If the list is duplicated after pressing the button only once, select the desired word from the duplicate list. If the button has a large number of alphabets arranged in the button, the number of cases that appear in the combination of characters will appear. As a result, the actual input efficiency is lowered. In addition, since Korean and Japanese are not fixed at the end part and the rear part is changed in various forms, the number of the many cases cannot be accommodated, and there is a problem in that the mother language cannot be applied.

In addition, the English keyboard that is currently employed in the miniature keyboard has a lot of time until the user is mastered in the use, since the 26 alphabets are simply arranged in each number button several times without any specific rule, and the input method is inefficient. Then, it is inconvenient to write a word or a sentence.

The present invention has been made in view of the above-mentioned matters, and it is possible to rearrange the characters on each key of the basic reduced keyboard in the 4 × 3 matrix format by a specific rule, and to perform the vowel or undisplayed subsequent consonant input function at approximately the center of the keyboard.

In addition, by allowing characters to be input by the combination of the key of the center point key or the key of the key, the user can be speeded up the character input and provide convenience in use.

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

2 is a view showing a character arrangement state of a keyboard for a small electronic device according to a first embodiment of the present invention.

Referring to FIG. 2, the keyboard for a small electronic device according to the first embodiment of the present invention is a 9-key basic keyboard, and as shown, 12 keys for inputting numbers, letters, and special symbols are 4 × 3. It has a determinant array.

The first key 201 is positioned in the first row and the first column, and the numbers '1', the English alphabets 'Q', and 'Z' are arranged in the horizontal order.

The second key 202 is positioned in the first row and the second column, and the numbers '2', the English alphabet 'B', and the 'C' are arranged in the transverse order at the top, and the English alphabet 'A' is disposed at the bottom. .

The third key 203 is located in the first row and the third column, and the numbers '3', the English alphabet 'D', and the 'F' are arranged in the transverse order at the top, and the English alphabet 'E' is disposed at the bottom. .

The fourth key 204 is located in the first row of the second row, and the numbers '4', the English alphabets 'G', 'H', and 'J' are arranged side by side at the top, and the English alphabet 'I' is It is placed at the bottom.

The fifth key 205 is located in the second row and the second column. The fifth key 205 serves as a center point key and inputs the number '5' and the English alphabet vowels A, E, I, O, U, and Y. Special symbols '+', the English alphabet 'K', and 'L' are arranged in this order in order.

The sixth key 206 is located in the second row and the third column, and the numbers '6', the English alphabet 'M', and the 'N' are arranged in the transverse order at the top, and the English alphabet 'O' is disposed at the bottom. .

The seventh key 207 is positioned in the first row of the third row, and the numerals '7', the English alphabets 'P', and 'R' are arranged in the transverse order.

The eighth key 208 is located in the second row of the third row, and the numbers '8', the English alphabets 'S', 'T', and 'V' are arranged in the transverse order at the top, and the English alphabet 'U' It is placed at the bottom.

The ninth key 209 is located in the third row and the third column, and the numbers '9', the English alphabet 'W', and the 'X' are arranged in the transverse order at the top, and the English alphabet 'Y' is disposed at the bottom. .

The tenth key 210 is positioned in the fourth row and the first column, and a special symbol '*' (asterisk) for a specific function is disposed.

The eleventh key 211 is located in the fourth row and the second column, and a number '0' (zero) is arranged.

The twelfth key 212 is located in the fourth row and the third column, and a special symbol '#' (sharp) is disposed for a specific function.

Here, the special symbol '+' having the vowel input function is arranged on the fifth key 205 because the fifth key 205 is located approximately at the center of the key arrangement structure of the keyboard. This is to consider the movement of the finger when inputting a vowel in the creation of a word or a sentence by key input, and to increase the input efficiency.

The character input method using a keyboard for a small electronic device having a 4 × 3 deterministic arrangement of 12 keys of the first key 201 to the twelfth key 212 as described above is the first key 201 to ninth. In order to input the English alphabet consonants arranged in the key 209, the second key 202, the third key 203, the second key 202, the third key 203, Input the English alphabet vowels (A, E, I, O, U, Y) arranged in the fourth key 204, the sixth key 206, the eighth key 208, and the ninth key 209, respectively. In order to do so, the fifth key 205 serving as a center point key is inputted by first hitting the first key, followed by the corresponding key having the vowel to be input. Here, the above input method will be described in detail.

That is, the English alphabet consonants arranged respectively with the numbers from the first key 201 to the ninth key 209 are input by sequentially increasing each key on which the corresponding consonants are arranged, and the vowels are the fifth key 205. ) (Hereinafter referred to as 'center key') is input by first hitting the corresponding key where each vowel is placed after 1 stroke. That is, in inputting a vowel, each vowel (A, E, I, O) arranged under the consonant group of six keys (202, 203, 204, 206, 208, 209) after one stroke of the 'center point (+) key' (fifth key) 205 is entered. , U, Y) is entered by typing the key where the desired vowel is placed.

This is represented by a combination of key numbers that include the 'center (+) key' (fifth key) in front (for convenience, a combination of Arabic numerals placed on each key), 52 = A, 53 = E, 54 = Expressed as I, 56 = O, 58 = U, 59 = Y, enter each vowel with a combination of these keys.

In the case of inputting the consonants, in the case of the fourth key 204, 'G' is inputted when the first stroke is hit, 'H' is hit when the second stroke is hit, and 'J' is hit when the third stroke is hit. Here, if the fourth key 204 is battered once more (that is, four batters), the first 'G' is input again. When the vowel 'I' in the fourth key 204 is to be input, first, the 'center point (+) key' (fifth key) 205 is hit one, and the fourth key 204 is one hit. If this is expressed as input form of key only, it becomes "5 + 4 = I". At this time, if the fourth key 204 is hit once again after hitting the fourth key 204, the consonant 'G' is input.

According to the above principle, if you want to input the English word "today", "8th key (208) double hit + center point (+) key (205) 1 stroke + 6th key (206) 1 stroke + 3rd key (203) 1 stroke + center point (+) key 205 1 stroke + second key 202 1 stroke + center point (+) key 205 1 stroke + ninth key 209 1 stroke ". If you express this more easily using only the Arabic numerals of each key, you get "88 + 56 + 3 + 52 + 59 = today".

On the other hand, in the character arrangement of the nine-key basic type keyboard shown in Fig. 2 as described above, the eight-key type is provided by placing <Q> and <Z> of the English alphabet consonant <QZ> arranged on the first key 201 on different keys, respectively. You can also configure the keyboard. That is, <Q> of the English alphabet consonants <QZ> of the first key 201 is rearranged in alphabetical order <PQR> to the seventh key 207, and <Z> to <WXZ> in the ninth key 209. 8-key keyboard can also be configured. Such an 8-key type keyboard structure and various character arrangement (array) structures described below can all be included in the technical spirit of the keyboard for a small electronic device of the present invention and are not contrary to the object and structure of the present invention.

In addition, in the arrangement and input of characters for any key of the keyboard, three characters including special characters and symbols are arranged in the upper row and the lower row of keys, respectively, and the characters arranged in the upper row are input by sequential increments. In addition, the characters arranged in the lower row may be configured to be input by sequential increment (ie, a combination of keys including the fifth key) after the stroke of the center point key (fifth key). For example, in the character arrangement of the first key 201, three characters (for example, the English alphabet "Q", "Z") and a special character and a sign are included in the upper row of the first key 201. Three characters "QZ?" Consisting of the "?" (Question mark) are placed, and three characters (for example, ", (comma)", ". (Period)", "! ) And three characters consisting of ",.!"), And the characters arranged in the upper column are sequentially incremented (that is, Q = 1, Z = 11,? = 111, where 1 is one stroke of the first key, 11 is double batter of the first key, 111 is triple batter of the first key), and letters arranged in the lower row are sequentially displaced after the first stroke of the center point key (fifth key). A combination of key numbers including 5 keys before, for example, 51 = "," (comma), 511 = "." (Period), 5111 = "?" (Question mark)]. By constructing such an input system, up to six plural characters (including special characters and symbols) can be arranged on one key if necessary.

Here, in inputting the non-displayed consonants or vowels, the futa (addition) of the fifth key 305 within a set time is valid until the last consonant or vowels of the undisplayed consonants or vowels are inputted (displayed). Do not recursively input (display) undisplayed consonants or vowels. The explanation will be explained further above.

In other words, when the first key 301 is described as an example, immediately after hitting the first key 301, if the "center point (+) key" (fifth key) 305 is hit (1), the English alphabet lowercase "q" is input. When this is expressed in the form of an expression, "P" + "+" = "q". At this time, if you hit the "center (+) key" (fifth key) 305 again (in the end, the first key 301 is one stroke, and then the fifth key 305 is a double batter), The English alphabet "r" is input. That is, "q" + "+" = r (= P + +), which is represented by the numeric number of the key, 1 = P, 15 = q, 155 = r.

On the other hand, in the seven-key reduced keyboard of the second embodiment as described above, consonants and vowels are rearranged to the respective keys of the first key 301 to the sixth key 306, that is, the first key 301: 1 < Pqr , Bcd, Jkl>, 2nd key 302: 2 <Ae, Mn>, 3rd key 303: 3 <Stv, Fgh, Xz>, 4th key 304: 4 <Iy>, 5th The key 305: 5 <+> and the sixth key 306: 6 <Ouw> may be rearranged to form a six-key keyboard having the same input method (principle) as the seven-key keyboard. Similarly, the arrangement of consonants and vowels is determined by the first key 301: 1 <Pqr, Bcd, Jkl>, the second key 302: 2 <Aei, Mn>, and the third key 303: 3 <Stv, Fgh , Xyz>, fifth key 305: 5 <+>, sixth key 306: 6 <Ouw>, and a five-key keyboard may be configured, and the arrangement of consonants and vowels may be arranged in the first key 301. : 1 <Pqr, Bcd, Jkl>, 2nd key (302): 2 <Aei, Mn, Ouw>, 3rd key (303): 3 <Stv, Fgh, Xyz>, 5th key (305): 5 It is also possible to configure a four-key keyboard with <+>.

Furthermore, the arrangement of consonants and vowels is determined by the first key 301: 1 <Pqr, Bcd, Jkl, Mn), the second key 302: 2 <+ AEI>, and the third key 303: 3 < You can also configure a three-key keyboard with Stv, Fgh, Ouw, Xyz>. However, in the 3-key keyboard, the display characters are entered as sequential blows, and the first subsequent letter after the sequential blows is the <center point (+) key> (here, the second key 302 serves as the center point key). Input as a futa (additional value), and the second subsequent letter is input as a <center point (+) key> stroke. Therefore, assuming that each other basic waiting time is < > for convenience of explanation, a key combination of < Pqr > of the first key 301 of the three-key keyboard is 1 & 12 & 21.
