One-hand input keyboard

Abstract

The invention discloses a one-hand input keyboard, which comprises multiple keys. Among the keys with characters, each key corresponds to a first-level input combination consisting of two characters or one character; the keys of each line are sorted from left to right when the right hand is used or from right to left when the left hand is used as follows: the five keys on the first line correspond to the character combinations 'YT', 'UR', 'IE', 'OW' and 'PQ' respectively; the four keys on the second line correspond to the character combinations 'HG', 'JF', 'KD' and 'LS' respectively; the characters 'A', 'N', 'B', 'M', 'V', 'C', 'X' and 'Z' are arranged on other keys in a manner that one key corresponds to one or two characters; for each key corresponding to two characters, when the key ispressed once, one character of the combination on corresponding key is input; and when the key is pressed twice continuously and quickly, the other character of the combination is input. The keyboardhas a small volume and is convenient to use and carry and favorable for rapid touch typing operation.

Description

technical field [0001] The invention relates to an input keyboard, which is a keyboard capable of rapid input with one hand, and is suitable for mobile phones, notebooks, computers, tablet computers, PDAs or other devices that need to input characters. Background technique [0002] As a character input device, a keyboard is widely used in computers, notebooks, typewriters, PADs, mobile phones and other electronic devices that need to input characters. [0003] The keyboard that computer is used is a kind of standard keyboard, and the most frequently used is 26 English letters and a space bar, and each English letter corresponds to a key on the standard keyboard, and "Space" space bar is an independent key. This single-key corresponding to single-character method does not need to switch and select letters (except upper and lower case) when inputting letters. Due to the clear division of labor between the ten fingers, fast touch typing with both hands can be realized. [00...

Problems solved by technology

[0005] However, the computer keyboard is designed based on two-hand input. Although the input is convenient, there are many keys. Except for the function keys, there are 47 keys for the input of letters, numbers and symbols, so the volume is relatively large.

Therefore, the keyboard is used as an independent external standard input device. This standard keyboard brings inconvenience to its movement and portability, and is not suitable for small and compact devices.

[0006] For some portable electronic products such as mobile phones, this standard keyboard cannot be used due to volume limitations. If a computer standard keyboard is used, the keys must be very small, and it is necessary to carefully stare at the keyboard to enter normally, and because the keys are small, it is easy to press the wrong key. or press the button more

Therefore, the number of keys needs to be reduced. For example, there are generally 12 character input keys on a mobile phone. Usually, a key on the key corresponds to 3-5 letters or numbers. Then when input is required, in addition to pressing the character key, you also need to press other keys to select The corresponding character on a button, or the input of a character that is sorted later by pressing multiple times in rapid succession, this input method greatly reduces the input efficiency

Moreover, although this key design is suitable for one-handed and one-finger input, it cannot fully mobilize five fingers to realize touch typing, and the input efficiency is very low

[0007] At present, there are many one-handed input keyboards, some of which only change the layout of the keys, but the number of keys is still large, and some have reduced the number of keys, but the combination of key characters is not scientific enough. Alphabetically arranged on the table, such as "AB", "CD", "EF"...; such as "ABC", "DEF", "GHI"...; or arranged in standard keyboard order, namely "QW", " ER", "TY"..., these methods are different from the finger operation habits of people using standard computer keyboards. Re-adaptation and learning, it is difficult to achieve fast input, even more difficult to achieve touch typing, and when using different keyboards to change the way, people will always feel uncomfortable, and for the huge user groups around the world, it is necessary to change their usage Habits are also a huge time and labor cost
