Universal single-hand keyboard

Abstract

A universal single-hand keyboard comprises a letter key area consists of 26 English letters. The letter keys are not less than two rows and four columns, transversely looking, key N, key G, key A and key I are located in the same row, key G is located between key N and key A, key A is located between key G and key I; key H is located right or obliquely below key I, the horizontal distance Beta from the center line of key H to the center line of key I has a width of 0-3 keys, and the row where key I is located and the row where key H is located are adjacently arranged or has 1-3 rows of other keys between. The keyboard can be operated with a single hand, the letter key area has a reasonable arrangement, the work efficiency with five fingers is extremely high, and the arrangement of the keys is easy to be remembered. With complete input function of 101 / 104 keys on the keyboard and slightly higher design of the space bar as well as with no need of special input method, the keyboard is more easy for realizing rapid touch typing with single hand; in addition, the keyboard also has the advantages of small and exquisite structure, easy portability and convenient use, etc.

Description

technical field [0001] The invention relates to a keyboard for information input, in particular to a universal one-handed keyboard. Background technique [0002] In the information age, computers have become an indispensable tool for human society, and computer keyboard input has become the most important way of human-computer interaction. Therefore, keyboards play a decisive role in the development of the entire human society. Most existing computer keyboards are standard keyboards with 101 / 104 keys, i.e. "QWERTY" keyboards. However, the "QWERTY" keyboard must use both hands to realize touch typing. Typing with both hands obviously consumes resources of both hands. Compared with typing with one hand, it reduces the labor efficiency of the human body and is a waste of resources; and the input efficiency of the "QWERTY" keyboard Not high. For English input, most typists are right-handed, but when using the "QWERTY" keyboard, the left hand takes up 57% of the work. The two li...

However, the "QWERTY" keyboard must use both hands to realize touch typing. Typing with both hands obviously consumes resources of both hands. Compared with typing with one hand, it reduces the labor efficiency of the human body and is a waste of resources; and the input efficiency of the "QWERTY" keyboard Not high. For English input, most typists are right-handed, but when using the "QWERTY" keyboard, the left hand takes up 57% of the work. The two little fingers and the left ring finger are the weakest fingers, but they are frequently used. The letters in the middle row only account for about 30% of the entire typing work. Therefore, in order to type a word, the fingers are often moved up and down, which not only has low typing efficiency, but also increases the labor intensity of the fingers; For Chinese input, the above problems also exist

[0003] In order to solve the above problems, people began to reform the key layout of the "QWERTY" keyboard, and some one-handed keyboards appeared, but the existing one-handed keyboards still have the following problems: a. It is impossible to achieve the unity of portable and efficient input. During the typing process, the flexibility and ability of each finger cannot be well utilized. The fingers also need to move and type frequently and long distances. Not only the typing efficiency is low, but the working intensity of the fingers is relatively high. b. It is difficult to realize fast touch typing, because the existing one-handed keyboards have not designed a space bar for one-handed typing; c. Most of the existing one-handed keyboards are designed as a part of some kind of industrial product, or Designed for special purposes, such as mobile phone keyboards, industrial computer keyboards, etc., rather than independent keyboards, there is basically no independent one-handed universal keyboard for sale on the market; d, most of the existing one-handed keyboards can only be called thumb keyboards, Because most of them are easy to use thumb keys, there are few keyboards with 5 finger keys
