Description

METHOD FOR INPUTTING ENGLISH CHARACTER USING ELECTRIC TELEPHONE KEYPAD

The present invention relates to a method of inputting an English letter using an electronic telephone keypad. More particularly, the alphabet of English is classified into a plurality of similar classification groups according to the pronunciation rules of Korean and assigned to each key button of the electronic telephone keypad. When an operation is applied to different preset key buttons for a key button of the English letter input method using an electronic telephone keypad configured to extract English consonants or English vowels corresponding to each different key button operation from the selected key button It is about.

Recently, with the expansion of general wired communication services, technical development and subscription to personal wireless communication services such as Personal Communication Service (PCS) based on Code Division Multiple Access (CDMA) technology. Thanks to the rapid increase in embroidery, various other additional services have been developed and are currently being actively serviced.

In particular, among such additional services, the text transmission service has been of particular interest to users due to the specificity of performing a text transmission function through a voice communication terminal.

In order to meet such needs, the applicant of the present invention needs to provide a useful character input system that can easily input a character to be provided through an electronic telephone keypad in order to provide such a character transmission service. The consonant group and Hangul short vowel group are divided and assigned to the concave-convex shape, and each key button uses three letters based on the frequency of use of a similar consonant group or similar vowel group each containing at least one consonant or short vowels. By sequentially writing in order of frequency, and extracting one consonant or short vowel code corresponding to different key button manipulations consisting of single push operation, double push operation, and long push operation among the selected similar vowel groups or similar consonant groups. 36 different key buttons Not only can you support all the combinations of Hangul alphabets as you speak the characters, you can significantly reduce the number of keybutton operations, and improve user-friendliness by allowing you to key in with both hands as you would with a standard keyboard. Korean Patent Application No. 98-2885, "Hangul code input method using an electronic telephone keypad" was previously filed.

However, in addition to the Hangul input system, a typical English character transfer service requires a useful alphabetic input system that can easily enter English, which is an international language through the electronic telephone keypad. In order to volunteer, consideration should be given to the consideration of independent language typography and the organic relationship between each language typography.

In other words, the multi-character typography is rich enough to represent all the characters that can be expressed in each language that you want to support, and the key button operation can be used when the user directly reproduces the character representation. The higher the degree of convenience of comprehensive operation such as simple and easy to understand keyboard layout of each language, the more desirable. In addition, it is easy to switch the input mode between each language input system. The deeper the relationship, the better the availability.

As an application field using English letter input method using electronic telephone keypad, it is possible to connect to stock information telephone service through telephone in addition to text transmission service, and then enter the desired domestic company name to apply to stock information service that informs the price. In addition, a variety of telephone voice information retrieval service systems, such as guides for domestic and foreign library collections, telephone reservations, and unmanned 114 services, can be used. Other applications include electronic notebooks and palmtops, which require fewer keyboards. Palm Top) A small comprehensive keyboard system such as a computer, a keyboard system as a substitute for operation and input devices such as an Internet TV, a digital still camera, and an input system having a similar structure and function, such as an electronic lock and an automatic teller machine. have.

To key in multiple characters using a small keypad with a limited number of key buttons, such as an electronic telephone keypad, you can effectively duplicate the letters of each language you want to support on the electronic telephone keypad and quickly You should be able to extract the letter you want.

Accordingly, various multi-character input systems are known to satisfy such technical needs. Representative prior applications related to the English letter input method using an electronic telephone keypad include Korean Patent Application Publication No. 95-007526 and Korean Patent. Korean Patent Application Publication No. 96-006547, Korean Patent Application Publication No. 96-020293, Korean Patent Application Publication No. 97-064093, and Korean Patent Application Publication No. 97-072848.

Among the published examples, the Hangul or English letter is stored in the storage means, and the Hangul or English is selected according to the Korean / English button, and the letter type of the selected language is displayed on the display means. Korean Patent Application Publication No. 96-006547, which selects a desired letter from the display means by operating a button, is a method of selecting the letter shown on the display means by using a direction button. It is inconvenient to input and has the disadvantage of unnecessarily increasing the number of key buttons pushed.

On the other hand, the well-known X coordinate, XY coordinate, and continuous push alphabet input method currently used in PCS phones, etc. may be using a separate mode conversion button (for example, LG Saire (trade name)). In addition, the function buttons such as the left and right arrow key buttons (→, ←) must be provided separately, and the number of operation of the key buttons is relatively high, and the inconvenience and burden such as the time required to read the coordinates of the keyboard are relatively high. Should be. In particular, the English character input method using the electronic telephone keypad according to the prior art enumerated above is very different from the character input system provided by a general word processor supporting English, and thus has a problem of degrading user friendliness.

The present invention has been devised to solve such a problem, and assigns an arrangement area of the English consonant group and the English vowel group according to the Hangul pronunciation rule on the electronic telephone keypad, and each key button corresponds to the Hangul pronunciation rule. Each of the three letters of the similar consonant group or the similar vowel group including at least one or more English consonants or English vowels classified as consonants or similar vowels are sequentially written based on the frequency of use, and then selected from the selected vowel group or similar consonant group. By extracting one English consonant or English vowel corresponding to the different key button operation consisting of push operation, double push operation and long push operation, it is possible to write 36 different letters using only 12 key buttons. Can support all combinations of By assigning four groups to the key buttons, the keyboard is easy to understand and the number of key button operations can be reduced dramatically. Also, the user can be keyed with both hands as in the standard keyboard. An object of the present invention is to provide an English letter input method using an electronic telephone keypad.

In order to achieve the above object, the English character input method using the electronic telephone keypad according to the present invention includes a number key button of "0" to "9" and a symbol / function key button of "*" and "#". In the English alphabet input method for inputting the English characters through the electronic telephone keypad; The alphabet of English is classified into a plurality of similar classification groups according to the Hangul pronunciation rule and assigned to each key button of the electronic telephone keypad, and when predetermined different key button manipulations for the respective key buttons are applied, the selected In order to input an English letter through a preset mode switching key button operation on the electronic telephone keypad in a preset electronic telephone keypad so that the English consonants or English vowels corresponding to the different key button operations are extracted from the key buttons. Switching the operation mode to an English character input mode; And extracting an English consonant or an English vowel corresponding to each of the different key button operations from any one of the respective key buttons.

Here, it is preferable that the plurality of similar classification groups are classified into English consonants and English vowel groups according to the Hangul pronunciation rules, and the arrangement areas of the English consonants and the English vowel groups are separately assigned to the electronic telephone keypad.

In addition, a similar consonant group including at least two consonants classified into similar consonants corresponding to the Hangul pronunciation rule among the English consonant group and the symbol / function characters is assigned to a similar consonant group key button, and the English vowel group and the symbol / function character are assigned. It is preferable to assign a similar vowel group including at least two vowels classified into similar vowels among the function letters to the similar vowel group key button.

On the other hand, the English consonants and the English vowels extracted by the different key button operations are lowercase letters, and if a predetermined uppercase letter switching keybutton operation is applied immediately after extracting the lowercase letters, the lowercase letters are preferably converted to uppercase letters.

The similar consonant group key button and the similar vowel group key button are each written in sequence of three characters in accordance with the frequency of use, and are controlled by three different key button operations consisting of a single push operation, a double push operation, and a long push operation. It is preferable to extract any one of the letters.

First, a general electronic telephone keypad will be briefly described to help understand the present invention.

1 is an exemplary view showing a general electronic telephone keypad.

In general, an electronic telephone keypad consists of a four-row, three-column key button array, and is arranged from left to right, and then from top to bottom in order of "1", "2", "3", "4", "5", "6" and "7". "8", "9", "*", "0" and "#" key buttons are assigned. When each key button is pushed, it cannot be imitated through human voice as shown in Table 1. By generating the dual tone conversion frequency (DTMF) consisting of a high frequency and a low frequency together, each key button can be uniquely identified.

TABLE 1

Hereinafter, a preferred embodiment of an English letter input method using an electronic telephone keypad according to the present invention will be described with reference to the accompanying drawings.

2 is a flowchart illustrating a preferred embodiment of an English letter input method using an electronic telephone keypad according to the present invention.

The core idea of the present invention is to classify the English alphabet into a plurality of similar classification groups according to the Hangul pronunciation rules, and assign them to each key button of the electronic telephone keypad, and preset different key button operations are applied to each key button. If so, the English consonants or English vowels corresponding to the operation of the different key buttons are extracted from the selected key button.

This is because, while Hangul is a complete language, English is a combinatorial language, so the rules for composing English characters through key input have a relatively simpler rule than Hangul.

Accordingly, after changing the character input mode to the English character input mode in the state set as described above, a process of simply extracting an English consonant or an English vowel corresponding to each different key button operation from one of the respective key buttons is performed. By repeatedly performing, English characters can be easily formed and input.

This will be described in more detail with reference to the embodiment of the present invention. First, in step S100, the arrangement area of the English consonant group and the English vowel group is divided into the arrangement of the concave-convex shape according to the Hangul pronunciation rule, and each key is assigned. In the button, a similar consonant group or a similar vowel group including at least one or more English consonants or English vowels classified into similar consonants or similar vowels corresponding to the Hangul pronunciation rule is sequentially written according to the frequency of use (step S110), and then, respectively. When the operation of the different key buttons for the similar consonant group or the similar vowel group key buttons is applied, the English consonants or the English vowels corresponding to the respective different key button operations are extracted from the selected similar vowel group key buttons or the similar consonant group key buttons. (Step S120).

One of the reasons for the alphabetical layout of the present invention according to the Hangul pronunciation rules is that even when the English alphabetical layout is organically subordinated to the Korean alphabetical layout or only English alphabetic keyboards are used independently, the alphabetical letters and vowel groups of Korean characters are recalled. This is to facilitate the familiarity. For example, in order to familiarize yourself with English keyboards, you should be familiar with Korean keyboards.

Therefore, for convenience of explanation, the English keyboard layout of the present invention will be described in detail through an embodiment of the Korean keyboard structure proposed in Korean Patent Application No. 98-2885, filed by the applicant of the present invention.

Figure 3a is a Korean patent application No. 98-2885, filed by the applicant of the present invention, the arrangement of the Hangul alphabet corresponding to the numeric key button of the electronic telephone keypad according to the "Hangul code input method using an electronic telephone keypad" FIG. 3B is an exemplary diagram showing an embodiment, and FIG. 3B is an exemplary diagram in which the Jamo arrangement of FIG. 3A is disposed on an electronic telephone keypad.

Figure 4a is an illustration showing an embodiment of the arrangement of the Hangul Jamo corresponding to the numeric key button of the electronic telephone keypad according to the present invention, Figure 4b is an example of arrangement of the Jamo arrangement of Figure 4a on the electronic telephone keypad It is also. FIG. 5 is an exemplary view showing the letter arrangement of FIGS. 3B and 4B in parallel with an electronic telephone keypad.

As can be seen in FIGS. 3, 4, and 5, in the present application, G, K, Q, N, L, M, T, D, P, B, V, S, C, R, X, Z, H, F are classified as English consonants, and A, J, O, I, Y, U, W, and E are classified as English vowels. However, in English, the letters W and J are semi-vowels or quasi-consonants used interchangeably as consonants and vowels, but for convenience, the letter W and J will be classified as vowels.

The English consonant group is classified into similar consonant groups grouped into Korean consonants, basic consonants, and basic consonants, which are easy to classify according to Hangul pronunciation rules, and reverses the iron ((j)) character to block each similar consonant group. `` 1 '', `` 2 '', `` 3 '', `` 4 '', `` 5 '', `` 6 '', `` 8 '' key button, which is an array of placed shapes. All key buttons in a row and a row, and a key button of a third row and a second column are arranged in parallel.

In this case, since the Korean consonants and the English consonants are not paired one-to-one in terms of the number or the similarity in pronunciation, it is preferable to consider the consonants having similarities as much as possible to form a similar consonant group, and the arrangement order within the same consonant group. The maximum similarity between Hangul and Hangul should be maintained as much as possible. However, the basic Korean consonants are a, b, c, d, k, k, k, k, k, k, yin, k, k, k, k, k. Refers to.

For example, in the case of Hangul consonants, the number 1 key button is a, ㄲ, ㅋ, the number 2 key button is ㄴ, ㄹ, ㅁ, and the number 3 key button is ㄷ. , 'ㄸ', 'ㅌ', '4' key button, 'ㅂ', 'ㅃ', 'ㅍ', '5' key button 's',' 」', symbol / function character' 'Del', '숫자', 'ㅉ', 'ㅊ' and '8', 'ㅎ' and the symbol / function character 'Enter' are written in sequence. If the Hangul consonants are arranged in the pseudo-consonant group key button, the arrangement of the English consonants according to the present invention corresponds to "G", "K", "Q" for the number 1 key button, and "L", " "M", "N", "T", "D" for the number 3 key buttons, "Cap" (capital letters), and the "4" key button for the "P", "B", " 'V', and '5', 'S', 'C' symbol / function letter 'Del' The `` 6 '' key button displays `` R '', `` X '', `` Z '', and the `` 8 '' key button contains `` H '', `` F '' and symbol / function characters `` enter '' in sequence. The English consonant group key button of the present invention corresponds to the pseudo consonant group key button.

On the other hand, in the English vowel family, not only the basic vowel and the main vowel ('1') have the same relationship as the preceding vowel, but also the Korean vowel and the English vowel have one-to-one in terms of number of vowels or similarities in pronunciation It is preferable to consider vowels having similarities as possible to form corresponding vowel groups as they are not paired with each other, and vowel numbers `` 7 ", symbol / function character" * ", number" 0 ", symbol character" # ", number" 9 "key button-That is, three rows of key buttons and three rows of three key buttons of the electronic telephone keypad, Place it on every keybutton in row 4.

For example, for Korean vowels, the number "7" key button "ㅏ", "ㅑ" "←", the number "9" key button "ㅗ", "ㅛ", the symbol / function character "→" '0' key button means 'TT', 'ㅠ', symbol / function character '. (Period)', symbol / function character '*' key button means 'ㅣ', 'ㅡ', symbol / function character 'space' Symbol, function character "#" key button, "ㅓ", "ㅕ", and symbol / function character "mode change" are placed together in sequence, and the Korean vowel consonant group key button is placed. The arrangement of the English vowel of the invention is "A", "J", "←" for the number "7" key button, "0" for the number "9" key button, symbol / function character "'(single quote)", Symbol / function character `` → '', numeral `` 0 '' key button `` U '', `` W '', symbol / function character ``. (Period) '', symbol / function character `` * '' key button `` I '', "Y", symbol / function The present invention is applied to Korean similar vowel group key buttons by sequentially writing characters "space", symbol / function character "#" key button, and "E", "" (double quotation mark), and symbol / function character "mode switching". Corresponds to the English vowel group key buttons.

In the above case, in the case of English consonants, the basic consonants of the exception can be arranged in a separate key button because not all the basic consonants have a rhythm and a vowel, and the extra button space is generated in the arrangement of the key buttons. So here you can assign symbols / function characters on a standard keyboard.

In addition, in the case of English vowels, as the number of vowels is small, an extra allocation space is generated in the arrangement of the key buttons, and here, the symbols / function characters on the standard keyboard can be usefully used.

The arrangement of English letters according to the concave-convex shape arrangement is to facilitate the familiarity of the English keyboard and to make key input using both hands.

In the following operation step, as described above, to enter English characters through the electronic telephone keypad, first, in step S200 to switch the operation mode to the English character input mode for English input through the electronic telephone keypad, In step S300, simply by repeatedly performing the process of extracting the English consonants or English vowels corresponding to the operation of each different key button from each of the similar consonant key button or the similar vowel key button, the English characters are easily made. Formation and input are possible.

As described above, the three consonant group key buttons and the similar vowel group key buttons are sequentially written in accordance with the frequency of use, respectively, by different key button operations composed of single push operation, double push operation, and long push operation. Extract any one of the three characters.

The single push operation corresponds to the first character in three character groups, the double push operation corresponds to the second character in three character groups, and the long push operation corresponds to the third character in three character groups. However, it is well known that such a correspondence method is for mapping a relatively simple key button operation to a letter having a high frequency of use of the letter in a general sentence.

Here, the operation method of the key button in more detail, single push operation (single push) operation is a simple push operation of the key button, similar to the single click of the mouse (double push), double push (double push) operation ) The operation is similar to the double click of the mouse. It is similar to the double click of the mouse, and the '*' key button is pressed twice to extend the recording time of the voice page of the pager. same. In addition, a long push operation refers to a key button operation method in which a key button is pressed for more than twice as long as a single push operation. These three key button operation methods are collectively named as a multiple push key button operation method. Shall be.

In addition, it is necessary to distinguish between uppercase and lowercase letters to be considered when inputting an alphabetic character. In the English alphabet input mode of the present application, when a separate key operation for inputting an uppercase letter is not performed, a lowercase letter is set to be extracted. To enter, additionally key in a letter to represent an uppercase letter.

In other words, the English consonants and the English vowels extracted by the respective different key button operations are lowercase letters, and if a predetermined uppercase letter switching keybutton operation is applied immediately after extracting the lowercase letters, the lowercase letters are converted to uppercase letters.

For example, in the case of the English character keyboard proposed by the present invention, the letter “3” is pushed to express that the English alphabet entered immediately before is capitalized.

On the other hand, the present application intends to facilitate the description of the present invention by unifying the mark on the document according to the key button operation method as follows. In other words, taking a number and a symbol / function character as an example, single push operation is written as 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, *, #, and double push operation is 1 ". , 2 ", 3", 4 ", 5", 6 ", 7". 8 ", 9", 0 ", *", # ", long push operation is 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 0-, *-, #-

For example, as an example for switching from the numeric input mode to the English character input mode, when the symbol / function character "#" key button is long pushed on the electronic telephone keypad of the present invention as shown in FIG. It can be set to be variable, in the present application will be expressed as '#-'.

Input to the English letter input method of the present invention described above to 'To be or not to be. The English sentence That is the question.'in the above-described notation of the present application, '33 -9 * -4 "# *-96 * -293 * -39 * -4" # 0-33-873 *-* 5 * -38 # *-1-0 # 53 * 920-8- '.

It is well known that arrangements of various key buttons can be derived within the scope not departing from the gist of the present invention in addition to the arrangement of the English letter keyboard presented above.

According to the present invention, the mechanism of tone generation by the key button push is the same as that of the conventional telephone apparatus, and only a method of recognizing the software is processed on the internal microprocessor such as a telephone or a PCS. Therefore, no additional hardware is required.

For reference, an example of a schematic hardware configuration around the microprocessor of the present invention may be one example of the accompanying FIG. 6. Furthermore, it is well known that a simple battery type external system module including a text and mode LCD and the like can be developed and used to connect to various telephones by hand.

Hereinafter, a quantitative comparison and evaluation result between an English letter input method (here, a multi-push method) using an electronic telephone keypad according to the present invention and a typical representative English letter input method will be described.

The ergonomic efficiency comparison brought about by the geometrical arrangement between the phoneme and the button suggests that if the optimal phoneme placement is proposed in each method, similar ratios of efficiency can be achieved, and so are the factors for proficiency. The arithmetic statistical comparison evaluation is performed based on the concept of the number of button operations, i.e., the time required for key button operation.

When the single push operation for operating a key button once is made from the number of unit operations to the unit time, different key buttons or the same key button continuous operation for a predetermined combination are calculated by 2 times and 3 times, and the same key button. It is assumed that a double push operation is applied 1.5 times, and a long push operation requires twice the number of operations and an operation time.

In consideration of the appearance rate (that is, the frequency of use), the effective comparison coefficient is obtained by dividing the number obtained by multiplying the number of operations and the appearance rate by the average appearance rate, as shown in Equation (1).

[Equation 1]

Figure 7a is a comparison graph showing the number of keyboard operations for the alphabet letter, respectively, the method according to the present invention, the conventional coordinate method, the continuous push method, the method using a standard keyboard, Figure 7b is a key button for each English character input method It is a comparative graph which shows the operation efficiency based on the continuous push method.

In the comparison graph, for convenience of notation, the method according to the present invention is marked as 'multi', and the conventional coordinate method is 'coordinate', the continuous push method is 'continuous', and the method using a standard keyboard is 'keyboard'. Each index is indicated. On the other hand, the comparative evaluation data was randomly extracted using the 'English Marshal Sorcerer-related articles on Mars probe,' consisting of a total of 5,400 characters when excluding spaces and sign characters such as periods and commas.

As shown in FIGS. 7A and 7B, in view of the frequency of appearance of each character (that is, the frequency of use), the multiple push method of the present invention improves the efficiency of 179% compared to the continuous push method and 176% compared to the coordinate method. Not only can it be seen that the efficiency is also close to 88% compared to a commercial standard keyboard.

Terminologies used herein are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a person skilled in the art, and the definitions should be made based on the contents throughout the present application. something to do.

In addition, since the present invention has been described in the preferred embodiment of the present invention, in view of the technical difficulty aspects of the present invention, those having ordinary skill in the art can easily be different from another embodiment of the present invention Since modifications may be made, it is obvious that both the embodiments and modifications cited in the above description belong to the claims of the present invention.
