Description

Alphanumeric input method {METHOD FOR INPUTTING WORD / NUMBER}

The present invention relates to a method of inputting a character, and more particularly, to a character input method suitable for inputting Korean, English, and numbers into an information communication terminal such as a portable communication device.

As is well known, in accordance with the spread of information communication terminals such as electronic organizers, portable communication devices, and the like, characters (eg, Korean, English, numbers, etc.) are frequently selected and inputted, and data is transmitted by input. Functions such as SMS (Short Message Service), electronic mail, and the like are provided.

Accordingly, various input methods for inputting characters have been proposed. Among Korean input methods, three keys are assigned to Hangul vowels and Korean consonants are input to assign Korean consonants and vowels by assigning Hangul consonants to a plurality of other keys. The English input method is used, and the English input method uses an English input method of assigning a key corresponding to each English character to a plurality of keys, and inputs the English by combining them. 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0) are assigned to one key, and a number input method of inputting a number is used.

Meanwhile, when the Hangul input method of Patent 10-0458280 (Hangul input method) patented by the present applicant is improved by improving the above-described Hangul input method, as shown in Table 1, the consonant or In the Hangul input method in which one or more vowels are assigned to each other and the Hangul is input by combining the consonants and vowels through the corresponding key, 'ㅣ' is a bell stem and 'ㅡ' is based on the shapes of the Hangul vowels. Named by the horizontal stem, the other shapes of the shape that follows the stem shape have one stem input function or one branch input function on a plurality of keys when naming them as the left branch, right branch, upper branch, or lower branch based on the direction. Or two or more are assigned, 'ㅣ' and 'ㅡ' are inputted through the vertical stem input function and the horizontal stem input function, respectively, and other vowels except 'ㅣ' and 'ㅡ' are inputted by the stem. A method for entering at least a combination of two or more types of input and neungdeul function.

collection Combination Order collection Combination Order ㅏ ㅣ (종), ㅡ (right) ㅐ ㅣ (species), ㅡ (right), (bok) ㅑ ㅣ (species), ㅡ (right), ㅡ (right) ㅒ ㅣ (species), ㅡ (right), ㅡ (right), (bok) ㅓ ㅣ (종), ㅣ (left) ㅔ ㅣ (종), ㅣ (left), (bok) ㅕ ㅣ (종), ㅣ (left), ㅣ (left) ㅖ ㅣ (종), ㅣ (left), ㅣ (left), (bok) ㅗ ㅡ (lateral), ㅡ (up) ㅘ ㅡ (lateral), ㅡ (up), (bok), (bok) ㅛ ㅡ (lateral), ㅡ (up), ㅡ (up) ㅙ ㅡ (lateral), ㅡ (up), (bok), (bok), (bok) TT ㅡ (lateral), ㅣ (bottom) ㅚ ㅡ (lateral), ㅡ (up), (bok) ㅠ ㅡ (lateral), ㅣ (lower), ㅣ (lower) ㅝ ㅡ (lateral), ㅣ (bottom), (bok), (bok) ㅡ ㅡ (lateral) ㅞ ㅡ (lateral), ㅣ (bottom), (bok), (bok), (bok) ㅣ ㅣ (species) ㅟ ㅡ (lateral), ㅣ (bottom), (bottom) ㅢ ㅡ (lateral), (bi)

In this case, when all the vowels are input, the first vowel divided into the vowels is input by combining the stem input key and the branch input key, and the remaining vowels are additionally input using the vowel input key. In Table 1, (horizontal) is horizontal stem input key, (species) is vertical stem input key, (upper) is upper branch input key, (lower) lower branch input key, (left) is left branch input key, (right) ) Denotes four input keys and (bok) denotes a double vowel input key.

In addition, when the above-described Korean Patent Publication No. 2003-0011122 (Korean input method using an initial consonant key) is previously described by improving the Korean input method, the Korean consonant input function or vowel input is input to a plurality of keys. In the Hangul input method in which one or more functions are assigned to each other and the Hangul is input by combining the consonants and vowels through the corresponding keys, the continuous consonants and the initial consonants assigned to the same key among the plurality of keys are sequentially When you want to input by using the first consonant to enter the consonant keys to enter.

Therefore, in the case of inputting a character according to the above-described character input method, at least ten keys must be assigned to each character so that the character can be inputted, and as the information communication terminal such as a portable communication device is miniaturized, the size of the keypad is also reduced. Although it is preferable to reduce the size of the keypad, it is difficult to reduce the size of the keypad because each key constituting the keypad displays a letter assigned to the corresponding key and must have a minimum size to be recognized by the user.

In addition, since most of the conventional character input methods are based on the principle of using a 3 * 4 matrix keypad, the number of keys constituting the keypad cannot be reduced, thus limiting the overall size of the keypad.

Accordingly, the present invention is to solve the above-mentioned problems of the prior art, in the case of the Hangul input in the information communication terminal, the basic consonants as the first and second basic consonant groups, respectively, each of the basic consonant groups first and second When the basic consonants other than the first and second basic consonant groups are classified into small groups, the first and second consonant input keys, the vowel input keys, and the first and second final consonant input keys are combined. The purpose of the present invention is to provide a character input method for inputting Hangul.

In addition, in the case of English input in the information communication terminal, the alphabet is classified into a single group, a left and right combination group, a top and bottom combination group, and a diagonal combination group and assigned to a plurality of keys. It is an object of the present invention to provide a character input method that can input a combination of different keys.

Finally, in the case of numeric input in the telecommunication terminal, the number group is classified into an odd group and an even group, and '0' is assigned to an even group, and assigned to a number when assigning a number to a plurality of keys in pairs of odd and even groups, respectively. It is an object of the present invention to provide a character input method capable of inputting a combination of keys.

In accordance with an aspect of the present invention, there is provided a character input method of allocating at least one or more Korean consonants and vowels to a plurality of keys constituting a keypad, and combining Korean characters through input of corresponding keys. When the remaining consonants except for the predetermined consonants among the basic consonants are classified into the first basic consonant group and the second basic consonant group, and each basic consonant group is further classified into the first small group and the second small group, among the plurality of keys Assign one or more keys to each of the first and second consonant keys for inputting the consonant and the first and second final consonant keys for inputting the final consonant, and the first subgroup is the first and second Input using only one of the first consonant key or the first and second final consonant keys, and the second subgroup is the first, second second consonant key or 1, first it provides a character input method for inputting a combination of the two trailing consonant key.

In another aspect, the present invention provides a character input method for inputting English characters through input of corresponding keys by allocating at least one alphabet to each of a plurality of keys constituting a keypad. At least one of them is assigned and divided into a single group, a left and right combination group, a top and bottom combination group, and a diagonal combination group, and the single group is selected by inputting a single key, and the left and right combination group selects a plurality of adjacent keys in the left and right directions. And input the plurality of vertical combination groups by selecting a plurality of adjacent keys in a vertical direction, and the diagonal combination group selects and inputs a plurality of adjacent keys in a diagonal direction.

Finally, in another aspect to achieve the above object, the present invention is a number input method for inputting a number through the input of the key by assigning a terminal number to each of the plurality of keys constituting the keypad, A number is classified into an odd group and an even group, and '0' is incorporated into the even group, and a plurality of pairs are formed by pairing one number belonging to the odd group and one number belonging to the even group, respectively. Numeric pairs are assigned to different keys constituting the keypad to select a corresponding key to input the assigned pair of numbers, but any number is input by the number of inputs.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

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

The core technical aspect of the present invention is different from the conventional method of inputting a character by providing at least ten or more character input keys of an information communication terminal, and in the case of Korean, the first and second consonant keys and the first and second finalities. The first and second basic consonant groups are assigned to the consonant keys, respectively, and classified into first and second subgroups. The first and second consonant keys and the first and second final consonant keys are combined and inputted. In the case of alphabets, the alphabet is divided into single group, left and right combination group, diagonal combination group and top and bottom combination group and assigned to the keypad.The combination of adjacent single keys according to the assigned single key or each group is entered. Classify the key into an odd group and an even group, assign one number of the odd group and one number of the even group to the plurality of keys in pairs, and combine the assigned keys with one or two or more By inputting, it is possible to easily achieve the purpose of the present invention through such technical means.

2 is a layout diagram of the Hangul alphabet of a keypad suitable for inputting Hangul in an information communication terminal according to the first embodiment of the present invention.

Referring to FIG. 2, the Hangul consonants and vowels are entered into the consonant keys 202 and 204, the vowel keys 206 and 208, and the final consonant keys 210 and 212 in order to input Hangul from the keypad provided in the information communication terminal. To place. Here, the first consonant key is (b, a, c, d, ㅁ) as the first basic consonant group among the basic consonants at 202 and the second basic consonant group (s, ㅎ, ㅇ, ㅂ, ㅈ). Is placed at 204, vowel key is placed at 206 and (-) is placed at 208, and the final consonant key is the same as the first consonant key in the first basic consonant group (b, (A), (c), (d), and (x) are assigned to the reference numeral 210, and (s, s, s, ㅂ, s) as the second basic consonant group at 212.

Here, reference numeral 202 and reference numeral 210 (b, a, c), reference numeral 204 and reference numeral 212 (o, u, u) denote first subgroups, reference numeral 202 and reference numeral 210 (d). , ㅁ), 204 and (12) of 212 are classified into second subgroups, respectively.

Next, a description will be given of a method for inputting Hangul with the keys arranged as described above in the information communication terminal.

First, when inputting a consonant consonant (b, a, c) which is the first subgroup of the first basic consonant group and (b, a, c) of 204 which is the first subgroup of the second basic consonant group ) Is inputted by pressing the arranged key once, twice, and three times, respectively, and the second small group of the first basic consonant group (d, ㅁ) and the second small group of the second basic consonant group Reference numeral 204 (s, ㅎ) is input by pressing another key once or twice after pressing the arranged key.

For example, as shown in Table 2, when the reference numeral 202 (b), which is the first subgroup of the first basic consonant group, is input, the key of the reference numeral 202 is pressed once to enter the first basic consonant group. In the case of inputting 202 (c) of the first small group, the key 202 is pressed three times. In addition, when inputting 202 (iii) which is the 1st small group of a 2nd basic consonant group, the key of 204 is pressed twice, and it inputs.

On the other hand, as shown in Table 2, when the reference numeral 202 (d), which is the second small group of the first basic consonant group, is input, the key of the numeral 202 is pressed once, and the key of the numeral 204 is successively pressed once. In the case of inputting the reference sign 202 (W) which is the second subgroup of the first basic consonant group, the key 202 is pressed once and then the key 204 is pressed twice in succession. In addition, in the case of inputting 204 (s) of the second small group of the second basic consonant group, the key 204 is pressed once, and the key 202 is continuously pressed once to input the second basic group. In the case of inputting (H) arranged at 204 which is the second small group of the consonant group, the key 204 is pressed once and the key 202 is successively pressed twice.

In addition, when naming the basic consonants except the first basic consonant group and the second basic consonant group as the derived consonants, when the derivative consonants are input as consonant consonants, they correspond to the basic consonants classified as the first subgroups in a 1: 1 ratio. After inputting a corresponding basic consonant, a derivative consonant is input by combining another key with the last input key. Here, the derivative consonants mean (ㅋ, ㅌ, ,, ㅅ).

For example, in the case of inputting a consonant consonant (ㅋ), a corresponding basic consonant (a) is input, that is, a key of 202 is pressed twice, and a key of 204 which is different from the key of the last selected 202 is selected. Press once to enter. In addition, in case of inputting the consonant consonant (), the corresponding basic consonant () is inputted, i.e., pressing the key of 204 three times and then pressing the key of 202 different from the one of the last selected reference 204 once. Press to enter.

On the other hand, when entering a consonant among the consonants, for example, (ㄲ, ㄸ, ㅃ, 중에, ㅉ), after inputting the terminal sound constituting the twin consonants, and selects and enters a key different from the last selected key. In other words, if you enter (ㄲ), enter (a), enter (ㄸ), enter (c), enter (ㅃ), enter (ㅂ), enter (ㅆ) If you enter, enter (ㅅ), and if you enter (ㅉ), enter (ㅈ), and then select a different key from the last selected key.

For example, in the case of inputting a double consonant (ㄲ), the user presses the key 202 twice to input the terminal sound (a), and then presses the key 202 different from the key 202, which is the last selected key, twice. In the case of inputting a double consonant (ㅆ), in order to input the terminal sound (S), the key of 204 and the key of 202 are pressed in succession, and then the key of 202 different from the key of the last selected 202 is used. Press once to enter.

In addition, in the case of vowel input, according to the Korean input method of patent 10-0458280 (Korean input method) patented by the present applicant, (ㅣ) is named as a stem stem, and (ㅡ) is called a horizontal stem, and the form is continued from the stem shape. The other shapes of are named left branch, right branch, upper branch, and lower branch based on the direction. In addition, the vowel input method includes a vertical stem input key, a horizontal stem input key, a left input key, a right input key, an upper input key, and a lower input key. Combination, but first enter the stem input key, then the branch input key to enter the vowel.

Herein, the functions of the vertical stem input key, the left branch input key, and the upper branch input key are assigned to the key 206, and the horizontal stem input key, the right branch input key, and the lower branch input key are assigned to the key 208. Assign a function and enter the vowel by pressing the corresponding number of combinations.

For example, as shown in Table 3, in the case of short vowel input using one key, when the key 206 is pressed once, twice, three times or four times, (ㅣ, ㅓ, ㅕ, ㅣ) is sequentially When the key 208 is pressed once, twice, three times, or four times, (-, ㅗ, ㅛ,-) is sequentially input.

In addition, in the case of short vowel input using two keys, when the key of 306 is pressed once and the key of 208 is pressed once and twice, (ㅏ, ㅑ) is sequentially inputted, and the symbol 208 When the key 206 is pressed once and twice in succession after pressing the key once, (TT, ㅠ) is input sequentially.

On the other hand, in the case of inputting the vowel vowels, as shown in Table 4, after separating the vowels into short vowels, the first short vowel is input by the above-mentioned short vowel input method, and the remaining vowels are indicated by reference numeral 206 according to the double vowel input function. The key and key 208 are selectively pressed to enter. Here, a key having a double vowel input function gives a double vowel input function to a key different from the last selected key at the time of inputting the first short vowel constituting the double vowel.

For example, as shown in Table 3, when a double vowel (ㅖ) is input, the short vowel (ㅕ) and the short vowel (ㅣ) are input. That is, after pressing the key 206 three times to input the short vowel, the user inputs the double vowel by pressing the key 208 different from the key of the last selected 206 to input the short vowel. do.

On the other hand, in the case of inputting a double vowel (하므로), when the key 206 is pressed in order to input (ㅣ) while (ㅡ) is input by the horizontal stem input key, the error (TT) is input. In this case, if the key 206 is pressed once, (TT) is pressed twice, (ㅠ) is pressed twice, and (ㅢ) is pressed three times.

In addition, in the case of entering the consonant consonants (b, a, c, d, ㅁ) as the first basic consonant group and the second basic consonant group (ㅅ, ㅎ, ㅇ) And the final consonant are inputted in the same manner as the method of inputting the first consonant by placing the reference numeral 212 at reference numeral 212. As an example, as shown in Table 2, the final consonant is input in a manner of inputting the initial consonant.

On the other hand, in the case of inputting three consonants consecutively (for example, in many cases) by connecting the consonant and the consonant in the Hangul input, the final consonant (b) is the first consonant key (i.e., the drawing). Key 210, and the final consonant (H) is input using the second first consonant key (i.e., key 204), and the initial consonant (o) is the second final consonant. The key is input using a key (i.e., key 212).

For example, in many cases, the first consonant (ㅁ) is inputted by pressing keys 202, 204, and 204 using the first and second first consonant keys, and the vowel (ㅏ) is a bell stem, Press the keys 206 and 208 by using the horizontal stem input key, and the final consonant (b) is input by pressing the key of 210 using the first final consonant key, and the final consonant (ㅎ). Is input by pressing keys 204, 202, 202 using the first and second consonant keys, and (o) is the first consonant by pressing the key 210 with the second final consonant key. , Vowel (-) is inputted by pressing the key 208 using the lateral stem input key, and (b) the final consonant is inputted by pressing the key of 210 using the first final consonant key.

On the other hand, in the above-described first embodiment, second embodiment, and third embodiment has been described as inputting the Hangul, English and numbers, respectively, but selectively inputting the Hangul, English and numbers by using a separate switching key Of course you can.

As described above, the present invention is different from the conventional method of inputting characters by providing at least ten or more character input keys of an information communication terminal, and in the case of Hangul, first and second consonant keys and first and second species The first and second basic consonant groups are assigned to the consonant keys, respectively, and classified into first and second subgroups. The first and second consonant keys and the first and second final consonant keys are combined and inputted. In the case of alphabets, the alphabet is divided into single group, left and right combination group, diagonal combination group and top and bottom combination group and assigned to the keypad.The combination of adjacent single keys according to the assigned single key or each group is entered. Classify the key into an odd group and an even group, assign one number of the odd group and one number of the even group to the plurality of keys in pairs, and combine one or more assigned keys By inputting characters, and with a minimum of key information from the communication terminal, it is possible to effectively input the Hangul, English and number.

Therefore, it is possible to reduce the size of the keypad for inputting characters of the information communication terminal, thereby reducing the size of the information communication terminal.
