That is, referring to the general structure of the English word, since the alphabet corresponding to the vowel key and the alphabet corresponding to the consonant key are often arranged repeatedly, the vowel key is arranged in the left column 110 and the center column ( 120) and the right column 130 by arranging consonant keys, the left hand and the right hand can be alternately input work, thereby improving the efficiency of the operation.

Here, the term 'terminal' refers to a terminal such as a mobile phone, a PDA, a computer, etc., and the term 'selection' means a key selection such as pressing a key, touching a touch pad, or selecting by a stylus pen. The concept includes all actions.

Hereinafter, the embodiment regarding the specific structure of a vowel key is explained in full detail.

English Vowels Frequency of appearance (%) E 11.1607 A 8.4966 I 7.5488 O 7.1635 U 3.6308

Table 1 shows the frequency of the appearance of vowels in English words, based on the report of Oxford (oxpord) company publishing an English dictionary.

(http://askoxford.com/asktheexperts/faq/aboutwords/frequency?)

As described above, when each key is capable of inputting a plurality of alphabets, and the plurality of alphabets are selected and displayed by the number of consecutive selection operations of each key, continuous selection of the vowel keys is performed. It is efficient to display the characters frequently used by the first selection operation.

Thus, as shown in Figs. 3 and 4, the vowel keys indicating E and A, which are the letters with the highest frequency of appearance, are separately arranged, and E, It is desirable to have the letter A displayed.

In addition, since it is efficient to arrange frequently used letters on the upper side of the column, as shown in FIG. 3, a vowel key indicating E is disposed on the upper side in the left column 110 and a vowel key indicating A is shown. It is preferable to arrange | position below.

As shown in Table 1, in the case of I, O, which is the next most frequent letter after E and A, it is efficient to be displayed by the second selection operation among successive selection operations of the vowel keys.

That is, in the left column 110, vowel keys indicating I and O are separately arranged, and the I, O characters are displayed by the second selection operation among successive selection operations of the vowel key. It is preferable.

On the other hand, when the selection operation of the input key is concentrated on some of the keys, the possibility of breakage of the corresponding key is higher than that of the other keys, which is not an efficient structure.

Therefore, the letters E and A displayed by the first selection operation, the letters I and O displayed by the second selection operation, and the U characters displayed by the third selection operation among the consecutive selection operations of the vowel keys take into account their frequency of appearance. It is preferable to arrange the two input keys.

That is, as shown in Fig. 3, it is efficient to separately arrange the vowel keys for E and I and the vowel keys for A, O and U.

In this configuration, if the frequency of each vowel key is calculated based on the frequency of appearance shown in Table 1, the vowel key indicating E, I is 18.70%, and the vowel key indicating A, O, U is 19.29 As a result, it is possible to obtain a result in which the selection operations for the two input keys are evenly distributed.

Hereinafter, embodiments of the specific configuration of the consonant keys will be described in detail.

The consonant keys are arranged in the center column 120 and the right column 130. In the case of the consonant keys, as in the case of the vowel key, in order to efficiently arrange the input keys in consideration of the occurrence frequency of the alphabet, The frequency of appearance was investigated.

In addition, in the case of consonants, in particular, considering the frequency of appearance as the first letter of the word will help to achieve a more efficient structure, a separate investigation on this.

In Table 4, alphabets are arranged in order of increasing frequency of appearing as the first letter of an English word, based on Table 3.

Overall ranking English consonants 11 H One S 12 G 2 T 13 F 3 R 14 W 4 C 15 Y 5 P 16 K 6 D 17 V 7 N 18 J 8 L 19 X 9 M 20 Z 10 B 21 Q

Table 5 shows a new ranking by combining Table 2 (ranking frequency of total English consonants in words) and Table 5 (ranking frequency of English consonants as first characters).

In the case of consonants, not only the total frequency appearing in the word, but also the case in which the frequency of appearance as the first letter of the word is considered to be more preferable in order to achieve a more efficient structure.

The criterion for assigning the overall ranking in Table 5 is to consider the total frequency of appearance and initial frequency of English consonants in a ratio of 1: 0.61308.

The ratio is based on the so-called golden ratio, which can be said to be the ideal ratio for giving psychological stability to humans.

Therefore, as shown in FIGS. 5 to 7, the central column 120 and the right column 130 are assigned S, T, R, C, P, which are ranked first to seventh among the 21 consonants. The consonant keys indicating D and N are separately arranged, and the S, T, R, C, P, D, and N characters are displayed by the first selection operation among the consecutive selection operations of the consonant keys. desirable.

On the basis of the above reasons, consonant keys indicating L, M, B, H, G, F, and W, which are ranked in the 8th to 14th positions, are respectively arranged separately, and the consonant keys are consecutively arranged. Preferably, the L, M, B, H, G, F, and W characters are displayed by the second selection operation.

In addition, consonant keys indicating Y, K, V, J, X, Z, and Q, which are ranked in the 15th to 21st positions, are separately arranged, and a third selection of the continuous selection operation of the consonant keys is performed. It is efficient to display the Y, K, V, J, X, Z, and Q characters by the operation.

That is, in assigning seven input keys as consonant keys, S, T, R, C, P, D, and N characters (family) are displayed by the first selection operation among consecutive selection operations of the consonant keys. In the second selection operation, L, M, B, H, G, F, and W characters (groups) are displayed, and in the third selection operation, Y, K, V, J, X, Z, and Q characters ( In the case of configuring the seven input keys by combining so as to be displayed, it is possible to obtain an ideal structure in which the total appearance frequency and initial appearance frequency of consonants among English words are comprehensively considered.

On the other hand, by preventing the selection operation of the input key from being concentrated on some keys, it is necessary to comprehensively consider the total appearance frequencies of the three groups of characters in order to obtain an efficient structure in which the possibility of breaking of the keys is evenly distributed.

Table 6 is divided into three groups of English consonants A, B, and C based on the overall ranking shown in Table 5, and the frequency of occurrence of three consonants selected from each group based on the frequency of occurrence shown in Table 3 above. The groups were combined into seven groups so that the sums appeared relatively evenly, and then each group was ranked according to the order of the sum of the frequency of appearance.

Therefore, as shown in FIG. 7, the consonant keys (1 group) for displaying S, G, and V, and the consonant keys (2 groups for displaying R, W, and Q in the center column 120 and the right column 130). ), N, B, Z consonant keys (3 groups), T, F, J, consonant keys (4 groups), P, L, X, consonant keys (5 groups), C, H When the seven consonant input keys are configured by the seven groups so that the consonant keys (6 groups) indicating K and the consonant keys (7 groups) indicating D, M, and Y are arranged separately, Since the frequency of use of the keys is evenly distributed, an efficient structure is obtained which evenly distributes the possibility of breakage.

In addition, it may be said that it is preferable to arrange the frequently used letters in the center row 120 as compared to the case in which the letters are arranged in the right row 130.

Accordingly, the central column 120 includes a consonant key for displaying the top 4 groups S, G, and V, a consonant key for displaying R, W, and Q, a consonant key for displaying N, B, and Z, T, F, and J. The consonant keys to display the consonant keys are arranged separately, and in the right column 130, the consonant keys to display the lower three groups P, L, and X, and the consonant keys to display C, H, and K, D, M, and Y are displayed. It is preferable to arrange consonant keys to be distinguished.

In addition, since it is efficient to arrange frequently used letters on the upper side, the central column 120 displays the consonant keys, R, W, and Q that display S, G, V from the upper side to the lower side according to the group rank. It is preferable to arrange the consonant keys, the consonant keys indicating N, B, and Z, and the consonant keys indicating T, F, and J in order.

In the case of the right column 130, a consonant key for displaying P, L, and X, a consonant key for displaying C, H, and K, and a consonant key for displaying D, M, and Y from the upper side to the lower side according to the group rank. It is preferable to arrange in order.

Hereinafter, the embodiment regarding a shift key is described.

In the case of a portable terminal, it is difficult to simultaneously select a shift key and another input key. Therefore, it is preferable to select another input key by the next operation once the shift key is selected.

After the shift key selection operation, when the consonant key or the vowel key selection operation is performed, the alphabetic uppercase letter is lowercase and the lowercase letter is changed to uppercase, thereby allowing selective input of uppercase and lowercase letters.

Furthermore, in the case of English, the uppercase letter is placed first, and a large number of lowercase letters are placed thereafter. After the shift key selection operation, the consonant key or vowel key selection operation is made after the consonant key or vowel key is selected. It is preferable to input an uppercase or lowercase letter of the alphabet before the shift key selection operation.

In other words, when inputting a lowercase letter, the shift key is selected once and the character key is selected once, and the uppercase letter is input. If the character key is immediately selected without selecting the shift key, the lowercase letter is input.

In addition, as shown in FIG. 7, in consideration of the balance between the seven groups of consonant keys arranged in the central column 120 and the right column 130, the shift key is formed by the left column ( It is preferable to be arranged at 110), and it is more preferable to be arranged under the vowel key in consideration of the advantage of taking a configuration similar to the keyboard layout of a general computer familiar to the general user and the frequency of its use.

The present invention provides an English input device for a terminal that can be used more conveniently and efficiently.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above Technical idea and the technical idea together with the basic will all be included in the scope of the present invention.
