JPH03262024A - One-hand input means for thumb shift keyboard - Google Patents

Abstract

PURPOSE:To enable one-hand operation and to reduce misdisplay by displaying all characters only with a key operation on a 1/2 input side obtained by dividing the thumb shift keyboard in the center. CONSTITUTION:The thumb shift keyboard is bisected in the center; and one side is regarded as an input side where keys are depressed and the other is regarded as a symmetric side. A memory is stored with 2nd codes indicating display characters as display characters displayed on keys on the symmetric side at symmetric positions with input-side keys while codes indicating display characters on keys on the input side are made correspond to codes of a shift key. When a character displayed on a symmetrical-side key of the thumb shift keyboard is displayed, the character can be displayed by depressing a key on the input side at the position symmetrical with a key on the symmetrical side and the shift key on the symmetrical side. Consequently, the character is displayed only by input-side key operation, so the one-hand operation is available to enable blind touch key operation, so keys are operated while characters displayed in an original are indicated by one hand to reduce misdisplaying.

[Detailed Description of the Invention] [Summary] The present invention has a thumb shift keyboard in which a character is clearly indicated on each key and a code is assigned to each key, and a display character corresponding to each code and code combination is indicated in the memory. A word processor that stores a first code table and, when a key with a specified character is pressed, finds a display character corresponding to the code of the pressed key from the first code table and displays it on the display device. , regarding a one-handed input method for a thumb-shift keyboard, with the aim of providing a one-handed input method for a thumb-shift keyboard that allows blind touching with one-handed operation, the thumb-shift keyboard is divided into two parts in the center, and one is used for inputting keys by typing keys. side, the other side is the symmetrical side, and the code indicating the display character by the key on the input side is combined with the code of the shift key, and the character specified on the key on the symmetrical side at the symmetrical position with the key on the input side is specified. A second code table to be displayed characters is stored in the memory, and the characters specified on the keys on the symmetric side of the thumb shift keyboard are displayed on the keys on the symmetric side and the keys on the input side in symmetric positions. The configuration is such that it can be displayed by keystrokes and shift keystrokes.

[Industrial application field]

The present invention relates to a one-handed input method using a thumb shift keyboard in a word processor that has a thumb shift keyboard in which characters are clearly indicated on each key and a code is assigned to each key, and displays displayed characters on a display device by keystrokes.

[Conventional technology]

Figure 4 is a block diagram of the main parts of an example word processor.
FIG. 5 is a diagram showing an example of the layout of a thumb shift keyboard;
FIG. 6 is a diagram showing code assignment to keys of an example of a thumb shift keyboard, and FIG. 7 is a diagram showing a code table of input code numbers versus display characters in a conventional ROM.

The configuration of the main parts of the word processor is as shown in Figure 4.
Processor 10.11 finger shift keyboard 11, keyboard control section 12. ROM13. It consists of a display device 14 and the like.

As shown in FIG. 5, the key arrangement of the thumb shift keyboard 11 is that the kana characters are arranged in three columns, and one key has two
Kana characters are arranged, and a shift key is arranged in a position that can be operated with the thumb to select the two kana characters.

In addition, each key is also arranged with alphabetic characters, and after pressing the alphabetic key,
When you press a key, the arranged alphabetic characters are displayed.

By arranging the thumb shift keyboard 11 as described above, you can press keys without looking at the keyboard (blind touch).
is now possible.

Characters are displayed on the display device 14 by keystrokes on the thumb shift keyboard 11 as described below.

As shown in Figure 6, a code number is assigned to each key, and by combining the code numbers of the key representing each character, the shift key, and the alphabetic katakana key, one of the three characters of each key can be set as a display character. A code table is stored in the ROM 13.

To explain this code table, for example, as shown in Fig. 7,
As shown in the code table of input code number vs. display character, when code number 35 (right key) is input, the displayed character is "K", and when code numbers 35 and 55 (right shift key) are input at the same time, the displayed character is "'". , for code number 30 (te key), the displayed character is "te", for code numbers 30 and 54 (left shift key), the displayed character is "napa", for code number 14 (letter key), for code number 14 (letter key) )After inputting, code number 35
The displayed character is "K" corresponding to the code number 30 (key), and the displayed character is "D'" corresponding to the code number 30 (key).

Therefore, for example, when the "ki" key is pressed, the keyboard control unit 12 knows that the "ki" key is pressed and the processor 10
Send code number 35 to.

Then, processor 10 determines that the display character corresponding to code number 35 is "ki" from the code table stored in ROM13.
Knowing this, "ki°" is displayed on the display device 14.

Also, if you press the right shift key and the "' key at the same time, the keyboard control unit 12 knows this and the processor 10
At the same time, send code number 35.55 to

Then, the processor 10 learns from the code table stored in the ROM 13 that the display character corresponding to the simultaneous input of code number 35.55 is "no", and displays "no" (above the character) on the display device 14. .

If you press the ``te'' key, ``te'' will be displayed in the same way, and if you press the ``te'' key and the left shift key at the same time, ``na'' (above te) will be displayed in the same way.

Furthermore, when the user presses the key "K" (the lower side is K) after pressing an alphabetic key, the keyboard control unit 12 recognizes this and notifies the processor 10 that code number 35 has been input after code number 14.

The processor 10 learns from the code table stored in the ROM 13 that the display character corresponding to the input of code number 35 after code number 14 is "l K 1'," and displays "K
” is displayed on the display device 14.

Furthermore, when the user presses the "te" (lower side is D) key after pressing an alphabetic key, the keyboard control unit 12 recognizes this and notifies the processor 10 that code number 30 has been input after code number 14.

The processor 10 learns from the code table stored in the ROM 13 that the display character corresponding to the input of code number 30 after code number 14 is "°D", and inputs "D I+".
is displayed on the display device 14.

[Problem to be solved by the invention]

However, when displaying characters exactly as in the original while looking at the original, typing the keys using both hands often leads to mistakes in keystrokes. In this case, if you type the keys with one hand while indicating the characters displayed on the document with one hand, you will be less likely to make mistakes in keystrokes, but if you try to type with one hand, you may not be able to reach some parts, making blind touching difficult.

An object of the present invention is to provide a one-handed input method for a thumb shift keyboard that allows blind touching with one-handed operation.

[Means to solve the problem]

FIG. 1 is a diagram of the principle of the present invention, in which (A) shows the layout of the thumb shift keyboard, (B) shows the code assignment to the keys,
(C) shows the code table.

As shown in Fig. 1 (A), it has a thumb shift keyboard in which a character is clearly indicated on each key, and a code is assigned to each key as shown in Fig. 1 (B), and the memory is stored in Fig. 1 ( As shown in C), a first code table 1 indicating display characters corresponding to each code and code combination is stored, and when a key with a character clearly displayed is pressed, the first code table 1 is displayed. In a word processor that finds a display character corresponding to the code of the pressed key and displays it on a display device, the thumb shift keyboard is divided into two parts at the center as shown by the thick line in FIG. The input side is the symmetric side, and as shown in Figure 1 (C), the keys on the input side and the code corresponding to the code of the shift key are combined with the code indicating the character displayed by the key on the input side. Storing in the memory a second code table 2 in which the characters specified on the keys on the symmetric side of the symmetric position are displayed characters, and displaying the characters specified on the keys on the symmetric side of the thumb shift keyboard are as follows: Display can be made by pressing the key on the symmetric side, the key on the input side at the symmetric position, and the shift key.

[For production]

According to the present invention, the code table 2 is stored in the memory in addition to the conventional code table 1, so that the characters specified on the keys on the input side are displayed by pressing the keys in the conventional manner. The character specified on the key on the symmetrical side can be displayed by pressing the key on the symmetrical side, the key on the input side at the symmetrical position, and the shift key.

In other words, it is possible to operate with one hand because only the keys on the input side need to be operated, and the characters clearly displayed on the keys on the symmetric side are displayed when the key on the symmetric side and the key on the input side at the symmetric position are pressed and the shift key is pressed. Blind touching is possible, and one hand can be used to indicate the characters to be displayed on the document, reducing display errors.

〔Example〕

Fig. 2 is a diagram showing the input code number 1 indicated character correspondence code table in the ROM of the embodiment of the present invention, and Fig. 3 is an explanatory diagram of keystrokes of the embodiment of the present invention. Indicates alphabetic characters,
・(B) shows the hiragana of the key.

In the case of the present invention, the display characters for code number 35 are stored in the ROM 13 in FIG. 4 as shown in FIG.
In addition to the conventional code table, the display character for simultaneous input of code numbers 35 and 55 is "no", and the display character for code number 35 after code number 14 is "K". If 55 is entered later, the displayed character will be "te", and if 55 is entered after code numbers 35 and 55 are entered at the same time, the displayed character will be "na", and after code number 14, the displayed character will be "na". Furthermore, when code number 55 is input, the displayed character is "D", and a code table is added that can also display the character specified on the left half key by a combination of the right half key press and the shift key press. be.

Therefore, if you press the key K (code number 35) shown in (A) after pressing an alphabetic key on the thumb shift keyboard shown in FIG. If you press the shift key on the right (code number 55) after pressing the K key, "D" will be displayed in the symmetrical position to K. In the case of the hiragana shown in (B), "K" (code number 35) If you press the key, "Paki" will be displayed as before, and if you press the key and the right shift key (code number 55) at the same time, "no" will be displayed as before, and after pressing the key, the right shift key will be displayed. If you press the key, “
” will be displayed, and after pressing the Shift key and the right shift key at the same time,
If you press the shift key on the right, it will move to the symmetrical position.
” is displayed.

In addition, in the case of voiced sounds, for the right half of the characters, as usual,
The left shift key is pressed at the same time, but for the character on the left, it is enough to press the character in the symmetrical position on the right and the left shift key at the same time, and then the right shift key. , for the characters on the right half, press the semi-voiced sound keys at the same time as before, but for the characters on the left,
All you have to do is press the symmetrical character on the right and the semi-voiced sound key at the same time, then press the shift key on the right.

Although the above description has been made with the input side as the right half, the same effect can of course be obtained even if the input side is the left half.

〔Effect of the invention〕

As explained in detail above, according to the present invention, all characters can be displayed by only operating the keys on the 1/2 input side, which is divided in the middle of the thumb shift keyboard, making it possible to operate with one hand. Displaying the specified characters can be done by pressing the key on the symmetrical side, the key on the input side at the symmetrical position, and the shift key, so blind touching is possible, and one hand can be displayed while pointing to the displayed character on the document. This has the effect of reducing display errors.
