JPH021011A - Row and column input key depressing method for kana based on extended kana syllabary and character arrangement of keyboard for this method - Google Patents

Abstract

PURPOSE:To reduce the burden on memorization of character arrangement by arranging keys for first depression in a group of the left or right hand and arranging keys for second depression in a group of the right or left hand for the purpose of expressing each of all voiceless sounds of the Japanese language with two strokes. CONSTITUTION:Keys corresponding to 9 rows of the systematic table of the fifty sounds are arranged on the left-hand side of a 28-key keyboard. Keys corresponding to 14 columns are arranged on the right-hand side. Keys corresponding to a voiced sound mark, a p-sound mark, and punctuation marks are arranged on the left-hand side, and keys corresponding to the syllabic nasal, assimilated sounds, and marks for punctuations or the like are arranged on the right-hand side. For the purpose of matching the key arrangement on the keyboard to associations of the systematic table of the fifty sounds, which the Japanese is familarized with, and taking the operability into consideration, keys corresponding to rows arranged on the left-hand side are collected to groups each of which consists of five characters in principle, that is, keys corresponding to first sounds 'k', 's', 't', and 'n' of rows and keys corresponding to first sounds 'h', 'm', 'y', 'r', and 'w' of rows are arranged in stages C and D of the keyboard respectively. With respect to columns arranged on the right-hand side, keys corresponding to sounds 'a', 'i', 'u', 'e', and 'o', keys corresponding to sounds 'ya', 'yu', 'yo', and 'wa' for contracted sounds, and keys corresponding to assimilated sounds, the syllabic nasal, and marks of punctuations or the like are arranged in stages C, D, and B respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention provides a kana-kanji system for Japanese word processors and computers that is easy to memorize and allows for highly efficient input as the proficiency increases. It concerns the typing method and character arrangement of a keyboard for inputting converted Japanese text.

(b) Conventional technical methods The character layouts of Japanese word processors or computer keyboards for inputting kana characters, which have been widely used in the past, can be roughly divided into [Japanese syllabary layout J, "JIS layout", and "new JIS layout". There are direct input methods using a keyboard with kana characters engraved on it, such as ``Thumb Shift Arrangement,'' and methods for indirectly inputting kana using Roman characters, such as ``Romaji Kana Input'' and ``M-style j.''

As is well known, when operating information devices such as word processors and personal computers, the requirements for a keyboard, which is the contact surface between humans and machines, can be summarized into the following two points.

(1) The character arrangement on the keyboard is easy to memorize and learn even for beginners.

(2) Excellent operability, such as efficient input speed improvement with relatively short practice.

From this point of view, when considering the above-mentioned models currently in practical use, the following problems can be pointed out.

The "Japanese 50 syllabary" system focuses on (1), and is familiar to the average Japanese person and easy to remember, but on the other hand, kana characters are arranged on a keyboard with 50 characters in 4 rows. Therefore, it is significantly inferior in terms of operability, and highly efficient input cannot be performed. rJls array" is the same (4 rows of kana characters 48
Not only is the operability inferior due to the individual arrangement, but
The drawback is that the keyboard layout is difficult to memorize.

On the other hand, the "parent shift array" method, the "new JIS
In the "arrangement" method, the number of keys is grouped into three rows of 31 to 32 by accommodating two characters for each key in order to enable so-called blind touch. In addition, as a result of seeking rationality in character placement by taking into consideration the frequency of use of each character, the flow line of Jl'r with both hands, etc., we have achieved results such as improving input speed for experienced users and shortening learning time. has been confirmed. however,
In all of these, the main focus is on increasing efficiency, so the arrangement of characters on the keyboard has no relation to the daily writing life of the average Japanese person, so beginners simply focus on increasing efficiency. There is no choice but to memorize the positions of the letters. It cannot be denied that this is the biggest obstacle for ordinary amateurs trying to use word processors and personal computers for document processing.

Next, another group of Romaji input systems use 23 keys out of 26 alphabento characters to spell out Japanese sentences in Romaji, and convert them into kana, thereby indirectly reading Japanese sentences. It is something that is expressed. Since this method has a small number of keys, it is easy for those who are accustomed to using Roman letters to perform H4 and blind touch, but in order to use this method, it is necessary to have the ability to write Japanese sentences in Roman letters. They must overcome another barrier: acquiring the .

To summarize the above, as long as the conventional technical method of placing symbols such as about 57 phonemes and about 6 punctuation marks, which are essential for writing Japanese sentences in kana, as individual letters and symbols on the keyboard, It is essentially difficult to satisfactorily satisfy the above two conditions (1) and (2). Even if it is possible to reduce the number of keys by storing two characters in - keys, arrange them in three rows, and use the shift key etc. to improve the j-shape of the hand and fingers, these characters and symbols There is no change in the fact that one is forced to bear a heavy mental burden in order to memorize the arrangement of the objects.

On the other hand, even when using the so-called indirect input method to avoid kana characters, which have a large absolute number, the conventional method relies on the Roman alphabet notation, so it assumes that the Roman alphabet has been learned. It cannot be denied that the written life imposes a double burden.

(c) Problems to be solved by the invention As seen above, the kana characters used for school in Japanese are 47 clear sounds, 20 voiced sounds, 5 half-voiced sounds, 1 cursive character, and 1 consonant character. In addition to the 3 elementary school letters for the consonant sounds, the 5 vowel elementary letters used to write foreign words, the F sound, the Cha sound, the Ua sound, etc., and 6 punctuation marks, etc., for a total of 88 characters. Even if a system is adopted in which dakuten and semi-voiced sounds are displayed by adding dakuten and half-dakuten symbols to clear sounds, the number cannot be reduced to less than 65g. Therefore, as before,
As long as we rely on the method of loading kana characters, symbols, etc. by imprinting them on the keyboard as they are, it is inevitable that we will be forced to memorize the arrangement of more than 60 characters, symbols, etc.

In this invention, all of the Japanese syllables are arranged according to the "enhanced syllabary chart" as shown in Table 1, with 9 <rows> and 3B <rows> for pre-transliteration of foreign words. Focusing on the fact that it can be uniquely identified as the intersection of <column> of 13IIl, 1
A total of 35 keystroke functions, including 2 rows, 13 columns, and 10 keystrokes such as dakuten, semi-dakuten, cursive sounds, consonants, and punctuation marks, are arranged on a total of 27111 keyboards on the left and right sides, and Japanese The purpose is to express a total of 163 syllables in kana, including the original 72 direct sounds, 36 consonants, and 53 consonants, consonants, and foreign words.

(d) Means to solve the problem As shown in Figure 1, there is a
The 9 〉 (ka, sa, ta, na: ha, ma, ya, ra, wa) of the "Expanded Alphabetical Chart" in the table, and the 3 〉 lines for before transliteration of foreign words. 〉 (fa, cha, ua), and place dakuten, handakuten, and punctuation marks (2,). On the right hand side, there are 13
Row> (A, I, U, E, O: Ya, Yu, Yonia, I, Tsu,
ku, o), syllabic sound (n), consonant sound (tsu), punctuation marks, etc. (
,. , -) symbols are placed.

At this time, the keyboard layout is the same as that which Japanese people are familiar with.
In order to match the association with the ``Japanese Alphabet Diagram,'' and taking into account operability as described later, the ``ku line'' is placed on the left hand side.
On the C and D stages of the keyboard, (ka, sa, ta,
): (ha, ma, ya, la, wa), and as a general rule, the <column> arranged in groups of 5 characters and placed on the right hand side is:
In the C, D, and B stages, respectively, (a, i, u, e, o), sulson (ya, yu, yo), consonant (tsu) = (a, i,
tsu, 工, o), and punctuation marks (, -・
).

For convenience of explanation, the characters on the keyboard before transliteration of foreign words are shown in katakana; however, in actual expression, conversion between hiragana and katakana can be freely selected using separate function keys. shall be.

Next, as one embodiment of the present invention, means related to a one-handed input keyboard, as set forth in claim 3, will be described.

As shown in Figure 5, 5 rows and 5 columns 251 [On the keyboard of a regular calculator consisting of the keyboard number 1, the ``Extended Alphabetical Chart'' row in Table 1〉 (ka, sa, ta, na), (Ha, ma, ya, ra,
wa), <row> for foreign tone articulation (fa, cha, ua)
and 1 發音 (n) are placed in the (B) stage and (D) stage, respectively. Also, <column>, consonant (tsu), dakuten,
Handakuten, punctuation marks, etc. are in the (C) column (A, I, U, E, O), and in the (E) column (Ya, Yu, Yo, Tsu, +1% O).
, (A) with (A, I, Tsu, Work, O) and (,.

-) is placed.

(E) Effect (1) Located on the right hand side and partially on the left hand side in Figure 1,
The 13 characters that indicate the columns of the "Expanded Alphabetical Chart" (a, i, u, e, o: ya, yu, yonia, ii, tsu, ko, o) and the positive and consonant sounds (n, ) and symbols (,.・-1,) are temporarily displayed by pressing each key individually.

However, for the B row on the right hand side where the letter or symbol 2H is placed on one key, pressing - will bring out the lower character/symbol, and pressing twice will bring up the upper 7, I, tsu, etc.
It is assumed that 〈〉,〈〉 are expressed.

For example, when the key [A] is pressed, the kana <A> is displayed, and when the key [Ya] is pressed, the kana <Y> is displayed. In addition, in the case of the key [n/a], it is assumed that - is used to display ``kun'', and a second key is used to express ``a''.

(2) All other characters in the "Expanded Alphabetical Chart" except for (1) above are ll? In the case of a sound, it is displayed by pressing the left-hand [row key] to which the character belongs, and then pressing the right-hand [column key] to which the character also belongs.

For example, to input <ki>, press the [Kake] key on the C stage on the left hand side, and then press the [I] key on the C stage on the right hand side. Also, in the case of ``Kushiyo'', hit the ``Sake'' on the left side, then hit the ``Yo'' on the right hand step. That is, by two strokes of the [row key] of the left hand and the [column key] of the right hand, [42
1 [1 can display all kana. In addition,
Hiragana and katakana are selected by operating a separate conversion key.

Next, if you want to input the ``nail'' in the voiced sound range, select the ``nail'' on the left-hand side.
Then, press the dakuten key on the B row on the left hand side, and then press the [i] key on the right hand side. For ``Kujiyo'', press the [Sa line] key on the left hand side, then press the dakuten key, and then press the [Yo] key on the right hand side. In the case of kana in the semi-voiced sound range, the procedure is the same as for kana in the voiced sound range, except that the semi-voiced sound key is pressed instead of the above-mentioned voiced sound key.

In the case of voiced and semi-voiced sounds, after pressing the [Row key] on the left hand side, press the [Column key] on the right hand side to display the In sound, and then press the voiced and semi-dakuten keys to produce the voiced and semi-voiced sounds. It also includes the method of converting it into a voiced sound.

(3) In particular, lines other than the ``Japanese syllabary'' that are provided to display foreign words, i.e., [F-line] and [Cha-line]
, 3 ft of [Ua]! I, respectively, on the left hand side [
is juxtaposed with the keys of [ ], [ya], and [wa]. In this case, the selection of the display character is done automatically.

For example, after pressing the [ha row] key on the left hand side, press the [a] key with the right hand.
If you hit , ``kuha'' will appear, if you hit ``ya'', kuhiya will appear, but if you hit ``a'', ``fa'' will appear.

Each of these is automatically selected by a pre-installed program.

Next, the operation of the one-handed input keyboard described in claim 3 will be described.

271I of the keyboard for two-handed input related to the above-mentioned claim 2! By loading the functions of two of the I keys, comma (1) and period (,), on the Roman alphabet keyboard shown in Figure 7, and compressing the number of keyboards to 25, a normal calculator can be used. It can be placed alongside a 25 full keyboard.

In this case, the method for inputting kana characters, punctuation marks, etc. is the same as described in the explanation of the input method regarding claim 2, except that the left and right hands are divided into two hands and the operation is performed with one hand. be.

(f) Effects of the Invention The effects of this invention will be discussed with respect to the following two points mentioned earlier in (b) evaluation of conventional technical methods.

(1) Reducing memory burden (2) Increasing efficiency through improved operability (1) (C) As mentioned in (1) (c), conventional keyboards for inputting Japanese text using kana-kanji conversion type input only 60 or so characters. In contrast to symbols, this invention is composed of 35 character/symbol elements, so the memory burden is significantly less. Also, considering all the syllables of Japanese kana as the intersection of the rows and columns of the ``Japanese syllabary''
For Japanese people who learned kana characters using the ``Japanese syllabary'' in the early stages of learning to write, there is no need to spend extra time memorizing the layout of the characters on the keyboard of this invention. Furthermore, in both <row> and <column>, Japanese people say, ``Following the H4 custom when reading the Japanese alphabet J aloud,
I, u, e, o〉, k(a)ka, sa, ta, na〉, 〈ha,
As a general rule, they are divided into groups of five syllables, such as ma, ya, la, wa〉, and are arranged on the 27 keyboards in three rows on the left and right sides, so it is easy to understand the sense of phrases. The movements of the fingers are linked, allowing rhythmic input without any physiological discomfort.

(2) In this invention, there is no need to use the soft key function, and all kana can be displayed by pressing 27 keys in 3 rows, resulting in excellent operability and eliminating the so-called blind touch. It's extremely easy to do. In addition, for most other kana syllables, excluding vowels, lowercase letters used to create succinct characters, punctuation marks, etc. that can be expressed by single keystrokes, use the [row key] on the left hand side and the c column key on the right hand side alternately. Because it is expressed by the strokes, the stroke can be performed extremely rhythmically.

Furthermore, as mentioned above, the present invention utilizes a keying method that uses the <row> and <column> elements of the ``Japanese 50-on diagram'', which is the basis of the daily writing life of Japanese people, to increase the number of keyboards. Although it is intended to minimize the memory burden and reduce the burden on memory, it is also objectively superior in terms of productivity and allows for highly efficient input work, as seen below.

In other words, in order to evaluate the efficiency of character layout on a keyboard, it was used in the Research Report on the Standardization of Japanese Information Processing (March 1985) edited by the Japan Electronics Industry Promotion Association. , when verified using the following indicators, the present invention has shown extremely excellent results as follows.

(a) The burden on the left hand is low (43.4%) and the burden on the right hand is high (56.6%).

(b) The alternating batting rate for the left and right hands reaches 96% of the total.

(C) The load on the home stage (stage 0) is significantly high at 75.1%.

(d) The little finger has a low load (11,1χ) and the index finger has a high load (53,7χ).

A comparison with conventional technical methods for each of the above IVI marks is shown in Figures (2) to (4).

As seen above, in (c), the problems set as problems to be solved, (1) reduction of the burden of writing tα of character arrangement, and (2) increase in efficiency due to improved operability, are achieved by the present invention. It is possible to solve the problems at the same time.

In addition, in the case according to claim 3, in order to enable one-handed input of kana characters with the keyboard of the 2511, the arrangement of Roman letters as shown in FIG. 7 and the arrangement of numbers and symbols as shown in FIG. In addition, by loading the ordinary calculator keyboard shown in FIG. 8, it is possible to provide the calculation function of an ordinary calculator with a document processing function using Japanese kana, Roman characters, numbers and symbols, etc.

The present invention provides a way to use advanced electronic information devices such as word processors and personal computers in the same way as traditional writing instruments and abacus.
It is open to the general amateur.
