Ask: Why are the letters on the keyboard arranged like this?

I believe many people can do it by computer blind typing. But have you ever thought about this question, is it that we are used to typing so skillfully that we don't have to look at the keyboard, or is there any scientific basis for the seemingly chaotic arrangement of letters on the keyboard?

This is an interesting question. Although the keyboard looked like this when we started typing, why did it look like this and is the arrangement of letters reasonable? Tian Jiangsen, vice president of Microsoft Asia Research Institute, said that most of the letters in the first row of keyboard numbers now start with QWERTY (also known as QWERTY keyboard), and its appearance is related to the old typewriter. Its wide use has come from the power of the market so far, just as some technologies have become industry standards, not because of scientific "perfection".

Christopher Sholes, the inventor of the first commercially valuable typewriter, and several friends churned out a typewriter with two rows of keys arranged in the order of the letter "ABC" like a piano. However, at that time, typewriters had to touch the metal arm with keys to type letters. When the control lever linked with adjacent letters did not completely return to its original position, the next letter could not be typed. After trying different keyboard arrangements, Sholes developed the QWERTY system to keep the letters that often appear together at a reasonable distance, make the typist's fingers move more distance, and reduce the time wasted by stopping because of jamming. QWERTY keyboard was born under such a demand. However, its patent owner is the famous weapon manufacturer E.Remington and his descendants. They not only skillfully used various means to popularize the QWERTY system, but also defeated the competitors who developed various keyboard sequences that were more effective and intuitive than the QWERTY keyboard, making the QWERTY system still the mainstream today.

In this era when full-screen smart phones dominate the world, only a few companies still insist on physical keyboards, and it is difficult to become the mainstream. A new generation of input methods using artificial intelligence to predict input content is gradually gaining favor in the market. For example, Microsoft SwiftKey, the world's first keyboard based on neural network, can capture the relationship and similarity between words in a meaningful way, and provide users with the most appropriate prediction or automatic correction of input sentences. This product has been installed in hundreds of millions of smart phones, and the Android version supports more than 15 languages, which is said to help users reduce nearly 1 trillion keystrokes.
