He put the most commonly used letters in the opposite direction, trying to slow down the typing speed and avoid getting stuck. Christopher Larsen Shoals applied for a patent for this design at 1868, and the first commercial typewriter with this layout was successfully put on the market at 1873. ?
However, in actual use, it is found that the layout efficiency of QWERTY's keyboard keys is very low. For example, people are usually right-handed, but the keyboard with QWERTY results does make the left hand bear 57% of the workload. The little finger and the ring finger of the left hand are both weak fingers, but they should be used frequently.
Letter lines only account for about 30% of the whole typing workload and are placed in the middle column of the keyboard. Therefore, in order to type a word, people often need to move their fingers up and down. ?
1888 held an open typing competition in the United States. A court stenographer named Ma Jialin typed blindly according to a clear fingering division. The speed is very fast, and the error is only three ten thousandths, which surprised everyone present.
According to the records, Ma Jialin won a prize of 500 dollars at that time. Since then, many people have begun to follow this typing method. Typing technology for the blind has become popular in the field of professional typing, and schools specializing in training typists have begun to appear in the United States. ?
