Why do “F” and “J” have haptic strokes on the keyboard?
Most keyboards have a haptic line under the letters “F” and “J”. this explains why that is.
Computer keyboards have become an integral part of our world. You can not only type letters and numbers with it, but also tons of special characters. But two buttons have a very special function and you can even feel it! Anyone who dares to take a closer look at the computer keyboard will see that the keys for the letters “F” and “J” have a small elevation in the form of a horizontal line at the bottom.
Why do the dashes exist at “F” and “J”?
If you write on the keyboard without looking at the keyboard, you can often not only rely on your sense of sight. The sense of touch is also used. The raised lines under “F” and “J” on keyboards play a major role in blind typing or ten-finger typing. They are a kind of tactile indicator for the Finger and placed where the two index fingers should ideally be in order to have a natural position on the keyboard. They are used so that the user can orientate himself with his fingers before typing on the keyboard.
Try it out by positioning your hands on the keyboard so that your right index finger is on the letter J and your left index finger on the F. When typing on a daily basis, one often unconsciously travels over these two centrally located keys without noticing the raised areas and feeling annoying.
IBM and Apple were keyboard pioneers
In the early 1980s, IBM was the number one computer manufacturer, and their keyboard design became the standard. Apple also established keyboards in a slightly modified form. In 1985, IBM introduced the Enhanced 101 keyboard layout. This is almost still the case today. The first keyboards did not yet have a dash under “F” and “J”. These came later.
