Ten-key collection keyboard

Abstract

The invention discloses a ten-key collection keyboard and belongs to the field of computer accessory equipment. The keyboard comprises ten keys. The keys are embedded onto a keyboard shell. A keyboard circuit and a code circuit are located in the keyboard shell. Communication interfaces are located on the keyboard shell and are connected with the code circuit. The ten keys of the keyboard correspond to ten fingers of a person respectively. Each key is of an oblong structure, the width of the upper surface of each key ranges from 1.3 centimeters to 2.5 centimeters, and the length of each key is at least twice that of the width of the key. In the using process, the person naturally puts the ten fingers on the ten keys of the keyboard and does not need to move the fingers when hitting the keys to carry out input, so long-term operation on the keyboard will not result in fatigue of the fingers and the wrists, possible wrong hitting in the touch typing and key finding process can be avoided, and the keystroke speed is increased. The ten-key collection keyboard is compact in structure and convenient to carry, keyboard operation under certain key position coding rules can be achieved, and the ten-key collection keyboard can be popularized and especially provides a computer input device for Braille users and special control industries.

Description

technical field [0001] The invention relates to a ten-key set keyboard, which belongs to the field of computer accessory equipment. Background technique [0002] As one of the input devices of the computer, the keyboard has a very high usage rate. After the keyboard is connected to the host, it can quickly realize text input and control the host; the conventional keyboard we use every day has many keys, and we need to constantly move the finger position when using it. Long-term use can cause finger and wrist fatigue, and even cause wrist diseases. In recent years, a series of keyboards have also been produced based on ergonomics to adapt to the convenience of finger keys when users use them. Existing keyboards are designed to be more difficult for visually impaired people to use. The current traditional computer keyboard adopts the working mode of one key and one input signal. To increase the number of input signals defined by each file, the number of keys must be increase...

AI Technical Summary

Problems solved by technology

[0004] To sum up, in the information age, it is a non-negligible demand for blind people to use computer networks to communicate and learn. The existing common input devices for sighted users are not suitable for blind users, and there is currently no effective keyboard input technology for blind users. Inspired by Blair's Braille, the present invention aims to provide a keyboard for the blind whose keys are consistent with the Braille system. The keys can provide text input such as Chinese characters

In addition, conventional keyboards take up a lot of space, and the keys of conventional keyboards generally correspond to 1-2 functions, which is poor in portability. In fact, it is possible to replace conventional keys with a small number of keys by formulating the combination rules of keys. This kind of collective keyboard with a small number of keys can also be used. Input control in special occasions, etc.
