Description

Hangul input device for information and communication equipment {HANGUL INPUT DEVICE FOR INFO-COMMUNICATIONS APPARATUS}

The present invention relates to a Hangul input device, and more particularly, to a Hangul input device of an information communication device to generate and input a Hangul code through a simplified key operation in an information communication device such as a telephone.

As is known, each phoneme is divided into a consonant, a consonant, and a consonant, and has a letter system that forms one syllable while being arranged two-dimensionally by combining a consonant with a consonant or consonant, a consonant, and a consonant. In other words, unlike English, where a single word is composed of only a phoneme and a space due to the two-dimensional arrangement of syllables, different characters are generated according to the arrangement of positions as well as the order of consonants and vowels. Accordingly, in implementing such an information communication device capable of inputting Hangul, various types of Hangul input methods and devices may be proposed according to an internal algorithm design method.

Recently, with the rapid development of information communication devices, miniaturization and multifunctionalization of various personal information terminals including general landline phones and mobile phones have been implemented, and one of the typical additional functions provided in such information communication devices is the Hangul input function. That is, in the conventional general mobile phone or some landline phones, one or more consonants and vowels of the Hangul are placed on each numeric key, which is usually provided, and then correspondingly according to the number of times and the operation time of each key. Korean consonants and vowels are inputted and the input consonants and vowels are combined based on a predetermined algorithm to complete the character.

Accordingly, in the conventional general information communication device, a Hangul input for generating a code corresponding to a consonant and a vowel of a Hangul according to an input key signal, and combining each generated consonant / vowel code based on a predetermined algorithm. The device will be embedded in the form of a processor or module.

Hangul input device or method for applying to such information and communication equipment has been developed and applied by a number of companies, the most representative method is the so-called 'Cheonjiin vowel input method' applied to mobile phones produced by Samsung Electronics. This cheonjiin vowel input method, as shown in Figure 1a, extracts the basic morphemes of each vowel of the Hangul and place them on the three buttons 'ㅡ', '·', 'ㅣ' and input all vowels through their permutations This is how to make it possible. And, as shown in the figure, 14 consonants and 14 consonants of consonants are arranged in each of the numeric keys of the telephone, and is configured to selectively input a flat sound or a sound in response to the number of times of operation of the key. According to such a vowel input method, the average number of key manipulations for inputting a single character is 3.89 times.

Another conventional Hangul input method may be a so-called 'Naratgle 2000' applied by LG Electronics Co., Ltd. to a mobile phone. As shown in FIG. 1B, six consonants among Korean consonants are configured as basic consonants, and the remaining consonants are configured to be input by a combination of a function button for assigning a role and a disease. The vowel is composed of six vowels of 'ㅏ / ㅓ', 'ㅗ / TT', 'ㅡ' and 'ㅣ' as the basic vowels, and the rest of the vowels are inputted by a combination of function buttons assigned the role of catching. have. According to the naragle 2000, the average number of key operations for inputting a single character is 3.45 times.

In another conventional Hangul input method, there is a so-called 'Sejongeul' Hangul code generation method, as shown in Figure 1c, each key button by arranging consonants and vowels on each key button to operate each key button once By inputting consonants or vowels, it is configured to input the 'end' button every time the input of a letter.

In addition to each of these methods, various Hangul input methods have been developed and applied.

However. In each of the conventional Hangul input method, there is a problem that the input time is long because a lot of key manipulation process is still required. Referring to each method described above as an example, first, in the case of the 'Cheonjiin vowel input method' illustrated in FIG. 1A, it is impossible to continuously input a specific character. For example, when entering the word 'country', theoretically enter '4', '3', '2', '4', '4', '1' and '2'. In this case, the word actually entered becomes 'guka' rather than 'country'. To prevent this, '4', '3', '2', and '4' must be input, and then '4', '1' and '2' must be input after a predetermined time. Therefore, there is a problem in that the input time becomes longer.

In addition, in the case of naraggle having a ruler / vowel arrangement structure as shown in FIG. 1B, the number of key manipulations is relatively reduced but the lack of consistency of the ruler / vowel arrangement is not easy to find the ruler / vowel on the keypad during initial use. Therefore, the user experiences many inconveniences until they are used to it. In addition, the long fingering distance in the process of inputting the actual Hangul, there is also a problem that the convenience is reduced.

In the case of 'Sejong' shown in FIG. 1C, as described above, since the 'end' button must be input every time each letter is input, the number of cumbersome key manipulations increases, and the input time also increases. There is a problem.

Accordingly, an object of the present invention is to provide a Hangul input device of an information and communication device that can shorten the Hangul input time as much as possible through a more simplified key operation. .

Each constituent means of the Hangul input device illustrated in FIG. 2 is built in a general information communication device such as a general telephone or a mobile phone, rather than configured as an independent separate constituent means. It is desirable to configure to share.

Referring to the drawings, the functions of the respective constituent means will be described. The keypad 10 is a key input means provided in an information communication device equipped with a Hangul input device according to the present invention, for example, a general telephone or a mobile telephone. Typically, a plurality of function keys, numeric keys, etc. are configured to generate a predetermined key signal corresponding to the user's operation.

The key signal processing unit 20 is a means for processing key signals generated from the keypad 10. The key signal processing unit 20 determines a key signal generated from each key and generates consonant and vowel code values of Korean characters corresponding thereto. Transfer to 30.

In addition, the autometer 30 combines each code value generated by the key signal processor 20 to generate a corresponding Hangul code and transmits it to the controller 40.

The controller 40 is a means for controlling the overall operations and functions of the Hangul input device according to the present invention. In particular, the controller 40 receives a Hangul code generated from the above-described autometer 30 and stores a Hangul font corresponding thereto. Read from the display 50 is displayed via the display unit 60 to be described later.

The font storage unit 50 stores a Korean font corresponding to each Hangul code value in advance, and the display unit 60 is a means for receiving and displaying a Korean font generated by the controller 40 as described above. It consists of LCD.

On the other hand, Figure 3 is a view showing a key arrangement form of the above-described keypad 10 according to the present invention, in the present invention, as shown in the same drawing, three basic figures extracted by separating the form of the vowel '-', Place a vowel key consisting of '·' and 'ㅣ', and then place the Korean consonants consistently and consistently on each of the other key buttons, and the rest of the consonants (ㅊ, ㅋ, ㅌ,, ㅎ) Place it between the keys.

The consonants arranged between the two keys in this way mean consonants generated when two adjacent keys are operated simultaneously, that is, when they are duplicated. For example, if the user wants to input 'ㄱ' by manipulating the keypad 10, the user will operate the 'ㄱ' key but wants to input 'ㅋ' existing between the 'ㄱ' and 'ㄴ' keys. In this case, while pressing 'b' while pressing 'b', the Hangul input device according to the present invention recognizes this as a key signal for 'ㅋ'. Likewise, if you want to input 'ㅎ', it is possible to press the 'ㅅ' key and 'ㅇ' key simultaneously.

And, each vowel key is configured such that the vowel is completed by a combination of left / right, up / down, similar to the 'Cheonjiin vowel input method' described above, the consonant ㄲ, ㄸ. ㅃ, ㅆ, and ㅉ are configured to be input by operating each of the consonant keys a, c, ㅂ,, and ㅈ twice in succession.

Table 1 shows consonants and vowels input in correspondence with each key button and the number of operations of the keypad 10.

Key button Input consonants (number of inputs) Key button Input bar 1 time Episode 2 long A A ㄲ One ㅣ + ㆍ ㅏ A + b Lol Lol ㅣ + ㆍ + ㆍ ㅑ N N N 2 ㆍ + ㅣ ㅓ ㄴ + ㄷ ㅌ ㅌ ㆍ + ㆍ + ㅣ ㅕ C C ㄸ 3 ㆍ + ㅗ D D D 4 ㆍ + ㆍ + ㅡ ㅛ M M M 5 ㅡ + ㆍ TT ㅁ + ㅂ ㅍ ㅍ ㅡ + ㆍ + ㆍ ㅠ ㅂ ㅂ ㅃ 6 ㅡ ㅡ S S ㅆ 7 ㅣ ㅣ ㅅ + ㅇ ㅎ ㅎ ㅇ ㅇ ㅇ 8 ㅇ + H H ㅈ ㅈ ㅉ 9

The Hangul input method according to the present invention will be described in detail with reference to specific examples.

If the user wants to enter the word 'coupon', the user inputs 'ㄱ' and 'ㄴ' at the same time (duplicate), and then enters 'ㅡ' followed by '·', and then 'ㅁ' and 'ㅂ' At the same time, followed by '·', 'ㅡ', and 'b'. That is, 'ㅋ' and 'ㄷ' of the 'coupon' can be enabled by simultaneously inputting 'ㄱ' + 'ㄴ' and 'ㅁ' + 'ㅂ', respectively.

According to the key arrangement and the Hangul input method in the Hangul input device according to the present invention, it is possible to further simplify the number of key operations compared to the conventional Hangul input method, thereby minimizing the overall input time.

In comparison with the conventional Korean input method described above, in the 'Cheonjiin vowel input method' illustrated in FIG. 1A, when a specific word, for example, a 'country' is inputted, each of the corresponding keys is continuously input. Contrary to the intention, it is entered as 'guka'. Therefore, while entering a 'country' after a predetermined time after entering 'country', in the present invention 'country', that is, 'b', 'a', '·', 'a', 'a' Since ',' | 'and' · 'can be input continuously, the input time can be shortened by that amount.

In addition, when compared with the naragle 2000 shown in Figure 1b described above, the Hangul input device according to the present invention is the first because the key arrangement of the keypad 10 is consistently sequentially arranged as shown in FIG. There is an advantage that the user can easily input Hangul.

In addition, when compared with the 'sejongal' shown in Figure 1c described above, there is an advantage that can reduce the inconvenience and the number of key operations due to the operation of the 'end' button.

First, in a state in which a user switches an overall operation mode of an information communication device equipped with a Hangul code generating device according to the present invention, for example, a general telephone or a mobile phone, to a message writing mode for Korean input (step S301), a keypad ( When each key included in 10) is operated to input a corresponding key signal (step S303), the key signal processing unit 20 based on the key signal generated from the keypad 10 corresponds to the ruler / vowel corresponding thereto. A code value is generated (step S305), and this is provided to the autometer 30. Then, the autometer 30 combines the provided character / vowel codes from the key signal processing unit 20 (step S307) to generate a corresponding Hangul code (step S309).

Subsequently, the controller 30 receives the Hangul code generated from the autometer 30, reads the Hangul font corresponding to it from the font storage unit 50, and provides the Hangul font to the display unit 60. As a result, the Hangul characters corresponding to the key signal input by the user are displayed on the display unit 60 (step S311).
