JPH07200120A - Adjacent character display keyboard - Google Patents

Abstract

PURPOSE:To easily and speedily input characters on a ten-key as to a personal computer, electronic calculator, electronic pocketbook, word processor, telephone set, etc. CONSTITUTION:For two-touch character input, characters for which the first key touch is operated by the same key, are put in the same group, and the key is decided as a group key. Then, 2nd key touches are made adjacent to the group key. The positions of the characters displayed on the group key indicate the positions of the 2nd key touch. Thus, the characters are displayed on the keyboard.

Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention can be used in fields in which full keyboards and numeric keyboards are used, such as personal computers, calculators, electronic notebooks, word processors, and telephones.

[0002]

2. Description of the Related Art Conventionally, in a notebook computer, for example, a full keyboard has been used as a key input device, or a pen input device has been used. In the case of an electronic notebook, for example, many keys are arranged in a rectangular shape and a character is selected from among them. With a calculator, for example, a numeric keyboard was used to select characters by pressing the same key several times.

[0003]

However, these character input methods have the following problems. (1) It was difficult to reduce the size of the full keyboard. (2) The pen input device has a low input speed. (3) The electronic notebook has a slow key input speed, making blind touch difficult. (4) A calculator such as a calculator in which a plurality of characters are assigned to one key is troublesome to input and has a problem in speed. The present invention solves these problems.

[0004]

[Means for Solving the Problems]

(1) For example, a ten-key pad having 3 rows × 4 columns (3 × 4) is used. (2) Input one character with two touches. (3) Determine the group and group key. (4) The second key touch position of the character in the group is made adjacent to the group key. (5) The position of the character displayed on the group key indicates the position of the second key touch.

[0005]

[Function] While looking at the keyboard or by blind touch, one character is input by two touches.

[0006]

【Example】

(1) A 3x4 numeric keyboard displayed as shown in "Fig. 1" for inputting alphabets. For example, (E, R,
T, D, F, G, C, V, B) are groups. For example, in order to input F, the group key in which F is displayed is pressed by the first touch, and the key in which F is displayed is pressed again by the second touch. To input R, press the group key where R is displayed with the first touch and press the key where R is displayed with the group key where R is displayed with the second touch, that is, press the key one level higher . To input C, press the group key where C is displayed in the first touch and press C in the direction where C is displayed in the second touch, that is, press the key diagonally below left . In this way
Since it is a numeric keypad, it is easy to touch and touch. Since the display on the keyboard is simple, it is easy to input while looking at the keyboard. (2) Displayed as "Fig. 2" to input Japanese 3
A x4 numeric keyboard. In this way, the characters of many countries can be supported. The arrangement of the numeric keypad can be expanded to 5x4 etc. if necessary. In addition, a mode conversion key can be provided to switch between uppercase and lowercase modes, and to switch between alphabetic characters and kana modes. (3) An example of a keyboard in which the Japanese and the alphabet are unified is shown in "Fig. 3". Here, the lower two keys have special function keys.

[0007]

EFFECTS OF THE INVENTION Since the present invention has such a structure, (1) It is possible to input characters like a full key with a numeric keypad on a personal computer, a calculator, an electronic notebook, a word processor, a telephone or the like. (2) Blind touch is easy. (3) The input speed is fast. (4) The position of the first touch and the position of the second touch can be known simply by looking at the display on the keyboard.

(4) A calculator such as a calculator in which a plurality of characters are assigned to one key is troublesome to input and has a problem in speed. The present invention solves these problems.

[0004]

[Means for Solving the Problems] (1) For example, a ten-key pad having three rows horizontally and four columns vertically (3 × 4) is used. (2) Input one character with two touches. (3) Determine the group and group key. (4) The second key touch position of the character in the group is made adjacent to the group key. (5) The position of the character displayed on the group key indicates the position of the second key touch.

[0005]

[Function] While looking at the keyboard or by blind-touching, input one character with two touches
