Who invented the first keyboard in history? . What does it look like?

Supplement the upstairs. Keyboards have a long history. As early as 17 14, people in Britain, America, France, Italy, Switzerland and other countries began to invent various types of typewriters. The earliest keyboards were used on typewriters with immature technology at that time. Why should the keyboard be standardized to the current "QWERTY" keyboard key layout? This is because the keyboards of typewriters are arranged alphabetically at first, and typewriters are all-mechanical typing tools, so if the typing speed is too fast, some key combinations are prone to key sticking problems. Shoals applied for a patent in 1868, and the first commercial typewriter with this layout was successfully put on the market in 1873. This is why there is today's keyboard arrangement. QWERTY's keyboard key layout is very inefficient. For example, most typists are right-handed, but with the QWERTY keyboard, the left hand takes up 57% of the work. The two little fingers and the ring finger of the left hand are the weakest fingers, but they are used frequently. The utilization rate of letters in the middle column only accounts for about 30% of the whole typing workload, so in order to type a word, you often have to move your fingers up and down.
