Method and Apparatus for Inputting the English Alphabet Using the Short Keypad {Method and Apparatus for inputting the English Alphabet Using the Shorten Keypad}

The present invention relates to an English alphabet input device and method using a reduced keyboard. In particular, the present invention relates to a miniaturized English letter input device and method useful for cellular phones, electronic notebooks, wrist watches, small word processes, personal computers, and the like.

The applicant of the present invention describes a reduced Hangul input method in the Korean patent application No. 1999-52648 in the name of the invention "a new Hangul input device and method based on the principle of Hunmin Jeong Heum disciple". The present invention is improved by applying the technique based on the "input method of Hangul input device and method" of the above application to the English letter input device.

In contrast to Korean, input of English letters is standardized by the International Telecommunications Union (ITU) for recommending a reduced-size keyboard layout for mobile phones (wired phones and mobile communication terminals). Recommendations from the International Union for Standardized English Keyboard Layout are the Canadian way (ITU E.161 / 1993 Option A, hereinafter abbreviated as Option A) and the Australian way (ITU E.161) proposed at the 1993 WTSC Assembly. / 1993 Option B, hereinafter abbreviated as Option B) has been proposed and used as a standard.

The keyboard arrangement according to option A, the Canadian proposed scheme, is shown in FIG. 1 (A) and the keyboard arrangement according to option B, the Australian proposed scheme, is shown in FIG. 1 (B). Then, after April 1, 1996, it was decided to unite the Canadian approach to international standards.

As can be seen in FIGS. 1A and 1B, option A and option B are similar. However, in option A, the keypad "1" is left blank, and the alphabetic characters are set to the keypads "2", "3", "4", "5", and "6" to the letters "ABC", "DEF", " GHI "," JKL "," MNO "are placed respectively, English letter" PRQS "is placed on keypad" 7 ", English letter" TUV "is placed on keypad" 8 ", English letter" WXYZ "on keypad" 9 " Place it. On the other hand, option B arranges the alphabetic character "QZ" on the keypad "1" and arranges the remaining alphabetic characters in alphabetical order of three characters on each keypad "2" to "9".

It is understood that the keyboard layouts of Option A and Option B, which are recommended by the ITU, define the keyboard layout, but not the input method.

Therefore, the reduced English alphabet input method and apparatus currently in use have been adopted as it is, or a slight modification of the recommendation option B of the ITU. For example, the modification is merely a modification such as arranging ".QZ" on the keypad "1" as shown in FIG.

As the method of inputting the characters of the keyboard arrangement, a repeated toggle type of the arranged character array is used, that is, the repeated toggle input method means that the characters assigned to the keypad "2" are 'A', 'B', for example. , 'C', the continuous input of button "2" is the same digit as 'A'-'B'-'C'-'2'-'A'-'B'-'C'-'2' A character is repeated in succession, and after selecting a character, the selected character refers to an input method that is input by, for example, pressing a space button or a confirmation button such as a left / right arrow (→, ←).

The toggle type input method described above has a problem in that a number of keypad manipulations are required, a separate character input confirmation button is required, and there is a difficulty in continuous input of characters, which requires a lot of time for character input.

SUMMARY OF THE INVENTION An object of the present invention has been made in view of the above problems, and the character arrangement uses the keyboard layout of Option B of the International Telecommunication Union, minimizes the toggle of the arranged characters, avoids repetitive toggles, and the number of operations of the keypad. It is to provide an input device and method that can significantly reduce the.

Another object of the present invention is to provide a miniaturized English input device and method capable of continuous input using a finite state converter.

Still another object of the present invention is to ensure versatility so that it can be used in all languages that use Roman characters such as French, German, Finnish, Swedish, and Vietnamese.

Operation example of input method 1

(Example 2)

In the input method 2 according to the second embodiment of the present invention, the keyboard layout of the variation of option B is selected as a specific keyboard. An operation example and a finite state transducer (FST) for the input method are shown in Table 2 and FIG. 4.

Description of overlapping portions of the keyboard arrangement shown in FIG. 1 (B) or FIG. 2, which is a variation thereof, will not be described again and will be omitted.

The difference between FIG. 1B and its modification is that in the keypad "1" 10 in FIG. 1B, "QZ" is arranged, whereas in FIG. 2, its variation, ".QZ" is arranged. There's only a minor difference. Therefore, only FIG. 2 will be described by way of example.

The difference between option A and option B described above is that in option A, the keypad "1" does not have an alphabetic alphabet, and the keypad "2" (10), the keypad "3" (30), the keypad "4" (40), Three alphabetic characters are arranged in sequence on the keypad "5" (50) and the keypad "6" (60), respectively, and the alphabetic character "PQRS" is arranged on the keypad "7" (70), and the keypad "8" (80). While the English letter "TUV" is arranged on the keypad and the English letter "WXYZ" is arranged on the keypad "9" (90), the alphabetic letter "PRS" on the keypad "7" (70) and the keypad "9" (90) and "WXY" was arranged, and the remaining alphabet "QZ" and the sign "." Were arranged on the keypad "1".

Therefore, since FIG. 1 (B) and FIG. 2 have three alphabetic characters arranged on each keypad as compared with FIG. 1 (A), it can be seen that the input method is relatively simple. That is, in the first embodiment described above, the keypad "7" 70 and the keypad "9" 90 are each arranged with four alphabetic characters, so that at least one or more keypads are used to input the last "S" and "Z". More manipulation was required.

It can be seen that Example 2 according to the present invention is the same as Example 1 except for the input of "S" and "Z".

Here, in the English letter ".QZ" arranged on the keypad "1" (10), the keypad "1" (10) is pressed once to input the symbol ".", And the keypad "to input the English letter" Q ". Press 1 "(10) and Symbol Keypad" * "(110). To input English letter" Z ", press Keypad" 1 "(10) and Symbol Keypad" # "(120) and enter number" 1 ". In order to do this, the keypad " 1 "

Operation example of input method 2

(Example 3)

Variations of Option A / Option B Keyboard Character Input

1. Exclusion of numeric entry

The input method according to the first embodiment and the second embodiment according to the present invention described above is a case where a number is included in the character input. Here, the 'number' input can be excluded from the character input. In other words, it is obvious that only a 'number' can be entered in the conversion mode separately from the alphabetic input.

2. Changing the Function Key Order

In the input method according to the first embodiment of the present invention and the input method according to the second embodiment, the keypad "*" 110 and the keypad "#" 120 are used as function keys used for character input. However, the order of use of the keypad "*" 110 and the keypad "#" 120 may be changed.

3. Addition of code input function

In addition, if necessary, it is also apparent that a keypad including additional functions and codes may be included in addition to the 12 standardized keypads. In other words, no input area other than the number is assigned to the keypad " 1 " of option A shown in Fig. 1A. In addition, only SPACE is assigned to the keypad "0".

Therefore, at present, in a mobile phone which is equipped with a web browser and can send and receive e-mail, '@', '.', '?', '!' As the frequency of use of these devices increases, these symbols can be assigned to the keypad "1" 110 or the keypad "0" 120 of option A, as shown in Table 3 below.

Enter target character Input Keypad Sequence '.' [1] + [*] '@' [1] + [#] '?' [1] + [*] + [*] '!' [1] + [#] + [#]

Additional function of sign input

It is clear that sign input is a function extension using an unused keypad and the set of sign characters can be extended and modified.

4. Entering Modified Characters with Option A / Option B

Option A / Option B For each of the two arrays, you can enter characters using character selection via movement.

When the keypad is pressed in each of option A / option B, the set representative character is selected, and based on the representative character, “*” and “#” respectively select a character while moving left and right in the character set assigned to the keypad.

Input Key Sequence Input character [2] 'A' [2] + [#] 'B' [2] + [#] + [#] 'C' [2] + [#] + [#] + [#] '2' [2] + [*] '2' [2] + [#] + [#] + [*] 'B'

When the character set assigned to the keypad "2" (20) is defined as the ordered circular list K (2) = <'A', 'B', 'C', '2'> Pressing the keypad "2" (20) selects the letter 'A', the first element in the K (2) list, and the symbol keypad "*" (110) and symbol keypad "#" (120) respectively. We define K (2) to search left and right. This method applies to both option A / option B methods.

5. Assignment of multilingual input support code

In general, in foreign languages other than English, in particular, in the case of German and French, the same symbols as the English alphabet are used, but symbols such as the umlaut “.” Are used. Therefore, as shown in Table 5, by arranging such symbols on keypad "1" or keypad "0" of option A, it is possible to achieve versatility among other foreign languages.

Enter target character Input Keypad Sequence '¨' [1] + [*] '˘' [1] + [#] ˚ [0] + [*] 'ˇ' [0] + [#]

Additional Functions for Code Entry Used in Other Foreign Languages

According to the above-described embodiment of the present invention, the character arrangement uses a keyboard arrangement according to Option A or Option B of the International Communication Union and variations thereof, minimizes the toggle of the arranged characters, and avoids repetitive toggles. In addition, the present invention can provide an input device and a method for drastically reducing the number of manipulations of a keypad.

In addition, according to an embodiment of the present invention, it is possible to provide a miniature English input device and method that can be continuously input using a finite state converter.

According to another embodiment of the present invention, it is possible to secure the versatility so that it can be used in all languages that use Roman characters such as French, German, Finnish, Swedish, and Vietnamese.
