Abstract

PROBLEM TO BE SOLVED: To implement a clear character input by displaying a string of characters to be input in positions near character input keys.SOLUTION: A character input device includes: a scroll pad 16 as character string selection means allowing a string of a predetermined number (for example, five in correspondence to the number of fingers of a single hand) of characters to be selected from many character strings; a display section 17 for displaying the selected character string; and keys 11-15 near the display section 17 as character selection means allowing a given character to be selected from the selected character string. Characters and symbols are input so as to be displayed on an input display screen or stored.

Description

  The present invention relates to a character input device such as a keyboard used for inputting characters and symbols, and a character input method using the same.

  Various key input methods for inputting various characters with a small number of keys have been proposed for miniaturization of keys.

FIG. 11 is a keyboard layout diagram of a keyboard for explaining the character input method disclosed in Patent Document 1.

  In FIG. 11, a keyboard 100 is a character input device for inputting characters such as English characters, Japanese characters, and numbers. English characters and Japanese characters include symbols accompanying English and Japanese sentences. Reference numerals 0 to 9, 11, and 12 are key tops (also referred to as keys) that are supported on the upper surface of the keys so as to be movable up and down. The keys 0 to 9, 11, and 12 are lightly urged upward by a spring as is well known.

  Keys 0 to 9 are arranged in a line on the left and right. The keys 11 and 12 are positioned in front of the keys 1 to 9 and 0 and arranged in a left and right row. Five left fingers are placed on keys 1-4, 11 and five right fingers are placed on keys 7-9, 0, 12. The left thumb is placed on the key 11 and the right thumb is placed on the key 12. The remaining left finger is placed on keys 1-4 and the remaining right finger is placed on keys 7-9,0. The index finger on the key 4 is moved and the key 5 is pressed, and the index finger on the key 7 is moved and the key 6 is pressed.

  This key arrangement can be substituted by a part of a standard key group, for example. For example, the keys 1 to 0 can be substituted by the middle key of the three-stage key group for inputting characters as standard keys, and the keys 11 and 12 can be substituted by the left and right keys of the SPACE key.

  Keys are also arranged on the left side of the key 1, the right side of the key 0, the left and right sides of the key 11, and the left and right sides of the key 12 because the little finger and thumb also move easily from side to side. Preferably, the SHIFT key or the CAPSLOCK key is arranged on the left side of the key 1 and the ENTER key is arranged on the right side of the key 0 like the standard key.

  In short, the keyboard 100 realizes the selection of the character keys at each level of the standard keys by simultaneously pressing the thumb key and another finger key. Further, for example, Japanese romaji input is realized by consonant selection by two-key simultaneous keystroke with one hand finger and vowel selection by one-key keystroke with the other finger thereafter.

  Therefore, since the number of keys can be reduced and finger movement can be prevented, there is little fatigue, and input after learning is very fast. Moreover, since learning is easy, even a standard key master can promote the transition. As a result, it is possible to provide a character input method and a key using the character input method that enable high-speed input while preventing fatigue, and further facilitate learning.

These are the key arrangement | sequence diagrams of the key for demonstrating the character input system currently disclosed by patent document 2. FIG.

FIG.
The keyboard 200 has a first key group 210, a second key group 220, a “δ key” 240, a “space key” 250 for inputting a space, and a “confirm key” 260 for inputting confirmation. doing.

  The first key group 210 includes five types of keys, “A key” 211, “I key” 212, “U key” 213, “E key” 214, and “O key” 215 for inputting vowels. .

  The second key group 220 includes a “K / G key” 221, an “S / Z key” 222, a “T / D key” 223, a “P / F key” 224, and an “N / NN key” 225 for inputting consonants. , “H / B key” 226, “M / X key” 227, “L / Q key” 228, “Y / J key” 229, “R / C key” 230, “W / V key” 231, and , “, .. key” 232 for inputting punctuation marks.

  Next, the reason why this key layout is suitable for inputting Japanese kana romaji will be described.

  When the “K / G key” 221 for inputting a consonant is pressed once, K is pressed twice and G is selected. When the “K / G key” 221 is pressed once and the “A key” 211 is pressed, KA is selected. When the “K / G key” 221 is pressed twice and the “A key” 211 is pressed, GA is set.

  Japanese kana romaji (representing 50 sounds) does not require all 26 letters of the alphabet, but in modern Japanese sentences, there are usually English words and Japanese letters and alphabets. Are used together.

  Therefore, it must be possible to input 26 letters of the alphabet. By dividing the kana romaji into the first key group 210 and the second key group 220, it is possible to input characters efficiently and easily.

  In short, in the keyboard 200, the first key group 210, which is a set of keys for inputting alphabetic vowels, and the second key group 220, which is a set of keys for inputting alphabetic consonants, are separately arranged. . Each key of the second key group 220 is assigned such that a clear sound is determined with a single keystroke and a corresponding muddy sound is determined with a second keystroke. Further, whether the same key is pressed once or whether the key is pressed twice is determined by the time when the same key is pressed. Further, the “δ key” 240 functions as a keystroke of the same key as that of the previous keystroke.

  As a result, it is possible to realize a small and easy-to-use key 200 having a relatively small number of keys and high operational efficiency (not requiring a large number of keystrokes).

It has mode changeover switches 21 to 23 such as a date character input mode and a symbol input mode.

  The scroll pad 16A displays a predetermined number (five here) of character strings in the display area of one line of the display unit 17 from the large number of character string groups of FIG. 3B stored in the storage unit. Scroll means for scrolling in the vertical direction of the array of the large number of character string groups and displaying them in the display area so as to select a predetermined number of character strings.

  The amount of movement of one scroll in the horizontal direction is moved in units of one character, or the selection range is moved in units of a predetermined number of character strings corresponding to the number of keys 11 to 15. When there are five input keys such as the keys 11 to 15, the selection range is also moved for each character string of five characters when selecting a character string by scrolling. As for the amount of vertical scroll movement, the selection range moves in units of one line.
