Description

How to enter multiple characters {inputting system of multiplex letter}

With the rapid development of electric and electronic technology, various kinds of electronic devices such as CDMA, PCS, TDMA, GSM, AMPS, IMT-2000, etc., have various types of mobile phones and PDAs, pagers, small game machines, remote controllers, cameras, appliances, etc. It is miniaturized and advanced. However, as the function of miniaturization is improved and the desire to express texts on electronic devices has increased, the necessity of inputting texts on these electronic devices has been increasing. In response to this, various methods (devices) for inputting Korean characters using a limited button (key pad) have been developed.

Electronic devices with liquid crystals, such as electronic notebooks and PDAs, have keyboard functions, pen-based functions, and computer keyboards and screens that can be directly touched.

In mobile phones and mobile terminals, a method of inputting text data into a small number of dial buttons (keys) of about 10 to 12 is mainstream.

The small appliances mentioned above are simple to use as input means by assigning and marking a single character data on a key, but most of the characters of various languages are not so many. The electronic devices mentioned above are miniaturized and the characters are input by pressing a small button several times to find and enter the necessary words, which is inefficient in terms of their input efficiency.

As a method of inputting a character into the above-mentioned home appliances, a multi-tap method is the basic and most commonly used as a method of inputting a character with a key arrangement and a character arrangement. The multi-tap method is inconvenient to use because it assigns and arranges a large number of character sets on a small number of keys in a superimposed manner. It was developed in a way to overcome this disadvantage is a character input method by a single tap (Single-tap). The special feature of this method is that a character is entered in one tap (key press). The biggest difference between the multi-tap and the single-tap method is that the single-tap method has a dictionary of the vocabulary (word) of the language in advance and the combination of the input character series is searched in the word dictionary, and if the matching vocabulary is in the dictionary, the vocabulary is automatically output Is based on an algorithm.

As already pointed out, a small number of keys and a small keypad are obliged to place multiple characters on a few keys, so the multi-tap method is the most basic way to access a character in the environment. It has the disadvantage of having a large number of key inputs and a large number of incorrect inputs during input. On the other hand, the single-tap method can reduce the number of keystrokes, but the system needs to be pre-configured, and the number of new items to be registered in the vocabulary dictionary will increase due to the increase in the use of new vocabulary and abbreviations of users. It is physically impossible to register in advance all vocabulary required in the information and communication environment such as homepage address. If the vocabulary is not registered in advance, the multi-tap method must be used inevitably, so the single tap method of one key per character has a limitation, and the combination of the number of characters entered and the dictionary based on the number of combination characters Another disadvantage is that the load on the system is high.

The object of the present invention is to improve the shortcomings or shortcomings of the multi-tap method and the single-tap method as described above, by dividing the characters into representative characters in a small keypad having a small number of keys, and marking the characters on the keypad. The purpose of this is to make it easy for the user to input the characters by grouping them into vowels, foreign words, special characters, and other user definitions by using the arrow keys.

1 is a flow chart of the Hangul consonants according to the present invention.

2 is a layout view of the direction key and the input unit according to the present invention.

Figure 3 is a detailed description of the direction key and the input unit according to the present invention.

In order to achieve the above object, a key feature of the present invention is to input a plurality of characters with a keypad having a number of about 12 keys, which can input the representative character key (1) and the up, down, left, right and the center designed in the present invention. It consists of a directional key 2.

1 shows a Korean representative character for each number.

Currently, Hangul input method is based on the 'Cheonjiin' input method, and the consonants and vowels are arranged on the key to input. The Cheonjiin method displays the characters representing Cheonjiin on the number plate and displays the rest of the consonants. It is marked on the number.

However, the order is different from Hangul's consonant order and arranged in the order of high frequency. However, the present invention is marked on the numbers in the Hangul consonant order.

2 illustrates a state in which the representative character key 1 and the directional key 2 are configured. The position of the directional key 2 can be configured to suit the shape of the electronic device in the upper, lower, left and right of the representative character key (1). This may be what it looks like, but it may also be what is displayed on the screen.

3 is divided into the directional key (2) and the Korean alphabet by the representative character key (1) is marked for each key.

[Table 1] below shows the letter group represented by 'ㄱ' to illustrate the present invention, [Table 2] represents the letter group represented by 'b', and [Table 3] represents 'c'. A group of characters is indicated.

The letters 'ㄱ', 'ㄴ', 'ㄷ', were given from left to right a to k on the basis of '·' in the stars and random coordinates from 1 to 0 from top to bottom. These arbitrary coordinates are for explaining the present invention.

In order to show the features of the present invention will be described by taking the above [Table 1] as an example. It shows that "ㄱ" is grouped by the representative character. The vowel part is based on the vowel order of Hangeul, based on cloth (·), ji (ㅡ), and phosphorus (ㅣ). '왼쪽', 'ㅑ', 'ㅐ', 'ㅒ' to the left, and 'ㅣ', 'ㅓ', 'ㅕ', 'ㅔ', 'ㅖ' to the right. 'ㅡ', 'TT', 'ㅠ' are displayed and 'ㅗ', 'ㅛ' at the top, and the vowels '음', 'ㅞ', 'ㅟ', 'ㅢ', 'ㅚ', 'ㅘ', 'ㅙ', and vowels such as 'ㅡ' and '모여' can't represent the vowel vowel in Hangul. This is common for Korean input.

The special characters can be input by the user or the producer according to the characteristics in any table of a1 ~ e5 on the upper left side, and can record the special characters according to the characteristics of each representative character. For example, 'ㄱ' is' parentheses', 'b' is' weather ',' c 'is a shape,' ㄹ 'is' Roman', 'ㅁ' is' shape ',' ㅂ 'is' box', ' ㅅ 'is' math', 'ㅇ' is' image ',' ㅈ 'is' terrain', 'ㅊ' is' physical ',' ㅋ 'is' Car', 't' is' table ', 'ㅎ' can be divided into 'arrow', 'ㅌ' and 'other', etc. to characterize special characters. This can be changed by the user or the producer.

The upper right portion f1 to k5 of [Table 1] is a foreign language part, and a user or a producer can insert upper and lower case letters of English and Japanese and other languages. And the rest of the space is free to insert special characters and foreign words according to the user's convenience.

As described above in the form of a table, all or a part of the table is displayed on the LCD screen or the display unit to visually express movement of the direction key.

In order to explain the character input method according to the present invention, for example, let's say the word "director ☆", to enter the first 'ㄱ', the representative character key (1) of the representative character key (1) marked [Table 1] Press key to display 'ㄱ' on the screen. Next, to input 'ㅏ', once the left button 8 of the directional key 2 of FIG. 4 is pressed once, the 'key' corresponding to g6 of 'a' of the representative character group described in [Table 1] is input. If you press the left button once more, it becomes h1, so 'ga' is inputted, and you have to enter 'ㅁ'.

Next, press the 3 key to enter 'ㄷ' first to enter 'dog'. When 'c' is displayed on the screen, press the upper button (6) of the arrow key 2 once, the 'degree' is displayed on the screen, and press the 1 key to enter the 'b'.

To input 'Nim', press '2' which corresponds to 'n' and 'n' is displayed on the screen. Press 'left' key (9) of direction key once, 'ni' is displayed and press '5' 'Nim' is completed.

Next, you need to enter '☆'. When entering existing characters, select special characters from the menu, then look at the entire character, select the corresponding character, and change to Korean mode again to input Korean characters. However, the present invention does not need to change the mode to a special character or a foreign language because special characters and foreign words are included in the representative character.

For example, '☆' is a figure, so if you press the No. 3 key, which is the key of the first letter of the figure, the key of the letter 'ㄷ', then press the arrow key (2) up (6) and the number 1 on the left (8). You can get the same value as above by pressing the arrow key (2) to the left (8) or up (6).

In the case of this design, the direction key plays the role of inputting vowels and special characters, so tapping the 'Menu' or other button on the keypad will switch to the correction mode and act as a direction key. .

In the conventional input method consisting mainly of Hangul, it was difficult to express special characters or foreign words. However, the character input method according to the present invention enables not only special characters and foreign words notation but also various characters defined by the user.

Japanese is also possible in the above manner.

The table below shows the Japanese character "よ し" divided by the method of the present invention.

The numeric number is the number of the key whose representative character is to be marked.

The input key of [Table 4] shows the direction button of the direction key (2), '·' indicates the center (10). '··' indicates that the center 10 is pressed twice or the representative character key is pressed twice.

[Table 5] below is an example of 'あ'.

TABLE 5

a b c d e One 2 い 3 お あ う 4 え 5

Based on the representative character in the center, 'い' on the top, 'う' on the right, 'え' on the bottom, and 'お' on the left are arranged. The empty space among the above items can be arbitrarily arranged by the user and the device manufacturer as described in the Hangul.

For example, let's take the example of 'よ し' input method.

The representative character of 'よ' is 'ゃ', so press the 9 key and press the arrow key (9).

The next letter is 'し', so press the number 3 key, which is representative 'さ', and press the upper button (6) once.

Other languages such as English, Chinese, Arabic, Russian, etc. can also set the representative characters and input characters according to the directions as described in Korean and Japanese.

As described in detail above, the number of key presses can be reduced when inputting characters according to the present invention, and various special characters and foreign words can be freely expressed.

Reduces the number of key inputs and the number of possible typos in the multi-tap method.

You can enter vowels of Korean characters and foreign words of special characters at once by typing the representative characters.

It is possible to reduce the keyboard of the electronic organizer and similar electronic devices.
