JPS63278114A - Japanese language input system by relative vowel method - Google Patents

Abstract

PURPOSE:To efficiently input the Japanese language by using the relative vowel method where the second stroke has a meaning relatively to the position of the first stroke and using a virtual keyboard together and displaying a help picture. CONSTITUTION:In case of the use of sixteen key pads, numeric and alphabetic codes are added on a keyboard and five sounds (a), (i), (u), (e), and (o) are displayed as vowels. For example, when the center key framed with a thick line is keyed for the first stroke corresponding to a consonant, the second stroke corresponding to a vowel corresponds to a code on the vowel display. That is, the relative vowel method where the second stroke has a meaning relatively is used to the position of the first stroke. The virtual keyboard is used together for a beginner to facilitate the operation or the same key is pressed down three times to display the help picture of special codes. Thus, the Japanese language can directly inputted at a high speed through a telephone and the Japanese language is efficiently inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an effective method for Japanese input. Many methods have been proposed to efficiently input Japanese for both ordinary people and experts, but no definitive version has yet emerged. The biggest reasons for this are the following two. A method that is easy for beginners to input does not improve input speed even if the user becomes proficient. It is difficult for beginners to get used to the methods used to increase the input speed of experts. The present invention is a method for solving these two points at the same time.

The present invention will be explained using a 16 keypad (FIG. 1). ■, ■ on the keyboard for convenience of explanation.

Symbols from ■ to ■, ■, ■, ■, ■, ■ are attached, and these symbols represent the keys to which they correspond in the following explanation and referenced charts. The concept of relative vowels that make up the following will be explained using Figure 2. The explanation here uses the five sounds of r aiweo J as vowels. When the key in the large frame in the center of FIG. 2 is pressed with the first stroke corresponding to a consonant, the second stroke corresponding to the vowel corresponds to, for example, the symbol in FIG. 2. This relative meaning of the second stroke with respect to the position of the first stroke is called the relative rl consonance method, named after the order of consonants and vowels in Roman alphabet input.

As an example of Japanese input using the relative vowel method, 5For example, when ■ is given the meaning of the consonant of ``ka line'', ``kakikukeko'' is ``(■■), (■■).

(■■), (■■), (■■)J. The notation 1' (XY)j introduced here indicates that the first stroke is the X key and the second stroke is the Y key. In the following explanations, inputs with three or more strokes may be expressed, and these will be expressed by increasing the number of key expressions in parentheses, such as r (XYZ)j, etc.

Now, according to one theory, the human keystroke speed of a highly skilled numeric keypad is said to be 800 keys/minute. It is said that 300 kana/min has been actually measured with two strokes of alternating left and right strokes, so it is considered reliable. From this, two-stroke kana input using a 10-key pad can be expected to take up to 400 kana inputs in 7 minutes, according to a highly skilled person, and is sufficiently ultra-fast.

Next, an example of a key layout according to the present invention that is easy for beginners to remember will be explained using FIGS. 3 and 4.

Corresponding to the symbols in FIG. 3, for example, ■ is set to r-row 1. As a voiced sound, "1" corresponds to "j" in ■■■■ "Hardness corresponds twice to j, and 1 line corresponds to yō sound in Figure 4. Figure 4 mainly shows vowels, but dakuten (dakuten) and the yō sound symbol.The voiced mark is represented by 1″j, and the yō sound is represented by fyJ.

In this embodiment, the voiced sounds and yaw sounds using these sounds require three or more strokes. Relative vowel keys after 2 strokes ``Aiweo J'' means the end of one kana input, and the dakuon symbol and the yo sound symbol indicate that the input has not yet ended. The reason for this is that the relative key position may not necessarily exist depending on the position of the consonant. For example,
This is obvious if you consider the key.

All of these are summarized in Table 1 as a keystroke correspondence table for relative vowel method kana input using a 16-key pad as an embodiment of the present invention. Column A is a row for each of the 50 sounds, and column B
The column represents the first stroke and is always present. Column E represents the final stroke and is always present. Below each key symbol in column E is written a kana character determined by the final stroke. Columns C and D represent intermediate strokes of characters that require three or more strokes. The exceptions are the consonants ``tsu j'', ``kuwa'', and r guwa 1. rJ is (■■), “Kwa”
is (■■), rguwa'' is (■■■). The expression shown in Table 1 is very complex at first glance, and beginners may find it difficult to remember. However, it is actually made up of very simple rules. Next, the rules will be explained.

It turns out that Time Table 1, which represents kana characters in Roman letters, is formed from the combination of Figures 5 and 6. Figure 5 corresponds to consonants. The exception is r-J, which represents row A. 6th
The figure shows the relative vowels adopted in this example, and there are four groups. The position of raj is the position of the first slot talk. The consonant groups and vowel groups correspond as follows. key■
Figure 6 (1) for the consonant rM-KGj corresponding to ■■
However, -t- is (2) for rRLTDPJ of ■■@, and (3) is for rN S Z YJ of ■■■, but ■
(4) corresponds to fHBWJ in (2). The relative vowel method adopted in this example is thus summarized in FIGS. 5 and 6. Table 1 shows the romaji representation of kana using these rules. Note that in this embodiment, ■■ primary keys are not used for kana input.

Now, it is not difficult to input kana in the straight line state using this embodiment. However, for beginners, it is difficult even if it is summarized in FIGS. 5 and 6. Furthermore, complete blind touching is considered essential for mastery. In this embodiment, a virtual keyboard is also used for this purpose.

The first screen of the virtual keyboard in this embodiment is the first screen.
7-- Figure 7 is shown. The second screen of the virtual keyboard differs depending on the state of the first stroke, but for example, the first stroke is f of the ■ key.
In the case of KJ, the virtual keyboard will be as shown in FIG. In this way, beginners can smoothly perform operations while looking at the virtual keyboard screen.

There are a wide variety of characters to be input, such as kana symbols, special symbols, alphanumeric characters, and foreign language characters.For example, Japanese Patent Application No.
As already described in 117880, there is a known method of inputting all data using Japanese phonetic readings. That is, for example, the method of inputting the $J symbol as ``Dorukigo J'' and ``rBj'' as ``rBj'' can of course be used in the present invention. However, frequently used symbols etc. need to be entered in at least three strokes. Next, a method for inputting special symbols and the like using three strokes in this embodiment will be explained.

In this embodiment, entry of special symbols is started using the ■ key, which is not used for kana input, but as an alternative method, entry can be made to the help screen by pressing the same key three times from the initial state. It is possible. still,
The initial state is the same state as when the clear key on a calculator is pressed, and is a state in which new input can be made. In this embodiment, the ■ key corresponds to the clear key. In the following, an input correspondence table for special symbols, etc. will be summarized in Table 2 using one example when the help key ■ is used. When the ['He1pj key ■ is pressed on the initial screen in FIG. 7, this corresponds to (1) in Table 2. When you press ■ in (1), (2), ■ (3), ■ (4), ■ (5), ■ (6), ■ ( 7) but
■ has (8), ■ has (9), ■ has (10),
In this embodiment, entry screens (11) and (12) correspond to (1) and (12), respectively.

In (1), the "Kanji j, r Hiragana J, r Katakana J keys that correspond to the ■■■ keys have special meanings in this embodiment, and after pressing these keys, the virtual keyboard returns to FIG. 7. However, , In the subsequent Onyomi input, when ■ is pressed in (1), it becomes 1 kanji input mode j, and ■
When is pressed, it becomes [Hiragana input mode], and when ■ is pressed, it becomes Katakana input mode 1. This allows you to switch between kanji, hiragana, and katakana with just two strokes. In the table from (2) to (12), press the rHelpJ key ■ to return to (1).The fcl and earJ keys ■ function to return to the initial screen in Figure 7 in all cases (1) to (12). do. still,(
If the rHelpJ key ■ is further pressed in step 1), the next main help screen will be displayed. In this example, (1
The main help screen following ) shall have the structure (13), where (Φ returns to the first help entry (1),
■ Returns to FIG. 7, ■ returns to the previous help screen, and ■ moves to the next help screen. In this way, in this example, 1
12 entry screens can be displayed on one help screen. In this way, in this embodiment, the number of help screens and entry screens can be increased as appropriate.

Furthermore, although the non-input method is basically intended for one-handed input, it is also possible to input with both hands. moreover,
By introducing shift keys such as ■■■ as shown in FIG. 9, it becomes possible to provide more functions to ■■■■. For even more flexibility, the fixed and relative meanings of the keys on the keypad can be made definable. The present invention enables high-speed input of Japanese directly even from a telephone.
