Abstract

The keyboard on many devices is small with only a limited number of keys. It is time-consuming and inconvenient to input many characters using such a keyboard. This invention adopts the scheme of 'inputting one character by pressing the keyboard two times, and, depending on the input order, different keyboard input could be accomplished'. It is fast and easy to remember. Furthermore, this invention suggests several scenario for inputting letters and ways to implement them. Using these schemes, hundreds of characters, including 26 letters in the alphabet both in upper and lower case, could be input from a 12-key keyboard, and no character could require pressing the keyboard more than two times.

Description

FIELD OF THE INVENTION

The invention relates to a keyboard input scheme.

Background of the invention

The keyboard area on many devices is small and the number of keys is limited. When many characters need to be typed, it is time-consuming and inconvenient. For example, the keyboard of an ordinary mobile phone has twelve character keys (0 to 9, *, #). To enter 26 English letters, you need to press the key multiple times. The input speed is slow, and lowercase letters cannot be entered.

Technical solutions

The purpose of the present invention is to provide a keyboard input scheme with fast input speed and easy to remember. Using this scheme, a 12-key keyboard can be used to input hundreds of characters including uppercase and lowercase characters of 26 letters. And no more than two keystrokes are entered per character.

In the case of a limited number of keyboard keys, the input scheme of "pressing two keystrokes to enter a character, the order of pressing two keys is different, and completing different keyboard input" can greatly increase the number of different characters allowed by the keyboard . The number of different characters allowed up to the square of the number of keys. In the following description, the key pressed first is referred to as the "front key" of the entered character, and the key pressed later is referred to as the "back key" of the entered character.

When adopting this scheme, it is necessary to provide a keyboard coding scheme that is easy to remember. Since in practical applications, letters are a type of characters with the highest input frequency, the present invention adopts three specific schemes for inputting alphabetic characters.

Option One:

In the following, the symbols AA ₂ A _{n are used to} represent n different letters. When n letters are input and the upper and lower case of A ₂ A _n ,

Specify 1 key X on the keyboard as the uppercase sum of the n letters AA ₂ A _n Lowercase common "front key";

Specify n keys P ₂ P _n on the keyboard; when inputting, press the X key first, and then press P _{l5 to} enter the upper case of the letter eight; first press the X key, then press P ₂ , and enter the capital ^; ...; first press the X key, then press P _n , and enter the capital of the letter 4 ₁₁ ; specify n keys (3 Q ₂ on the keyboard) that are different from P ₂ P _n

Q „; When typing, first press the X key, and then press the lower case of the letter eight ₁ ; first press the X key, then press Q ₂ and enter the lower case of the letter ^;…; first press the X key, then press Hit Q _n and enter the lowercase letter A _n ;

In the following description, the keys P ₂ P _n are referred to as the “upper case key group” of the key X; the keys ^ and Q ₂ Q _n are referred to as the “lower case key group” of the key X.

The advantage of this method is that all the letters corresponding to the "front key" can be printed on the "front key" in sequence, and each key in the upper case key group or lower case key group is arranged according to the rules such as rows and columns. Suppose the user needs to enter the mth letter printed on the "front key" and press the "front" key. After that, he can quickly find the mth key arranged in the upper or lower case key group. For example, Figure 1 Let the uppercase key group of key 2 be 1 key, 2 key, and 3 key, and the lower case key group be 7 key, 8 key, and 9 key. To input uppercase "B", first press "B" "front key" 2 Key, and then press the 2 key at the second position in the upper case key group; To input the lower case "b", first press the "front key" 2 key of "b", and then press the lower case key at the second position. 8-bit key.

Using this scheme, you can enter 26 letters of upper and lower case and other characters with 9 keys. For example, in Figure 2, there are 9 keys in the 1st, 2nd, and 3rd rows. The 1st key is the two-letter "front key", and the other keys are the three-letter "front key". The upper and lower case key groups of each key can be any two of the three horizontal rows, or any two of the three vertical columns.

Based on the first solution above, for the 12-key keyboard, there can be two implementation solutions:

Implementation plan one: The 26 letters are divided into 9 groups, of which 1 group is 2 letters, and the remaining groups are 3 letters each. Each group of letters is a "front key" by a key in the number key group;

Nine keys are arranged in 3 rows and 3 columns. According to the principle of scheme 1, the uppercase and lowercase key groups corresponding to each "front key" are selected from 3 rows or from 3 columns.

This embodiment can be used for a 12-key keypad commonly used in telephones and mobile phones. Figure 2 is a keyboard key layout and character assignment diagram. In the figure, the first row of keys is an uppercase key group, and the second row of keys is a lowercase key group, where "Q" and "Z" are on the 1 key. Figure 6 shows the keyboard coding table.

Implementation scheme two:

The 26 letters are divided into 8 groups, of which 2 groups are 4 letters each, and the remaining groups are 3 letters each. Each group of letters is used as a "front key" by a key in the number key group;

This embodiment can be used for a 12-key keypad commonly used in telephones and mobile phones. Figure 3 is a keyboard key layout and character assignment diagram. In the figure, the first row of keys is an uppercase key group, and the second row of keys is a lowercase key group, where "Q" and "Z" are on the 7 key and 9 Key. Figure 7 shows the keyboard coding table.

Option II:

When entering uppercase and lowercase letters,

One letter corresponds to two keys designated on the keyboard, hereinafter referred to as key X and key Y;

First press the X button, then press the Y button, and enter the capitalization of the previous letter;

First press the Y button, then press the X button, and enter the lowercase letters.

In this solution, in order to input letters, numbers, and other characters at the same time, you can specify that the 9 keys on the keyboard correspond to a total of 9 numeric symbols from 1 to 9; press any one of these 9 keys twice in a row, Enter the number corresponding to the key.

For the 12-key keyboard, the second scheme has two specific implementation schemes. Implementation scheme one,

This embodiment can be used for a 12-key keypad commonly used in telephones and mobile phones. Fig. 4 is a keyboard key arrangement and character assignment diagram for inputting letters, numbers and other characters using 9 keys in the keyboard, where "Q" and "Z" are on 1 key. Figure 8 shows the keyboard coding table.

Embodiment two,

This embodiment can be used for a 12-key keypad commonly used in telephones and mobile phones. Fig. 5 is a keyboard key arrangement and character assignment diagram for inputting letters, numbers, and other characters using the nine keys of the keyboard, where "Q" and "Z" are on the 7 key and the 9 key respectively. Figure 9 shows the keyboard coding table.

third solution:

Scheme three is similar to scheme one. The only difference is that the "front key" and "back key" are reversed, that is, two keys are pressed for each character input. Change to click later; the button pressed later in plan one becomes the first click in plan three. Each of the above solutions uses an input method of pressing a key twice to enter a character. In order to quickly input a small number of characters, the keyboard should have two input modes: "double-click input mode" and "click-click input mode". In double-click input mode, press the key twice to complete a keyboard entry and enter a character; in single-click input mode, press the key once to complete a keyboard entry and enter a character. You can specify a key in the keyboard. When in the double-click input mode, press the key to enter the single-click input mode. When in the single-click input mode, press the key to enter the single-click input mode.

In order to make it easier for the inputter to recognize the keyboard, when the "front keys" of several characters are the same key, the foregoing characters can be marked on the "front keys", and the foregoing characters are on the "front keys" of the front fan The order of the The "back keys" are arranged in the same order on the keyboard. In the keyboard shown in FIG. 4 or FIG. 5, the characters on each key have been arranged according to the above rules. For example, if you want to enter the capital letter "A", first find the 2 key where "A" is located, press the 2 key, and then press the 4 key according to the position marked by the "A" on the 2 key to enter the "A".

By using the input scheme provided by the present invention, the number of different characters input can reach the square of the number of keyboard keys on the premise that the keystroke is not more than twice for each character input. BRIEF DESCRIPTION OF THE DRAWINGS
