When
the typewriter debuted in the 1860s, the keys were laid out in what
seemed like a logical way. They were arranged like piano keys and
organized alphabetically. Eventually, the arrangement of the keys
changed to their current layout: the QWERTY keyboard.
This
keyboard was created so that the most common letters were spaced far
enough apart to prevent the letter bars of the typewriter to get tangled
with each other, causing a typewriter jam. And even though typewriters
eventually became obsolete, QWERTY stuck around. In 1936, Dr. August
Dvorak created the Dvorak simplified keyboard to allow for the most
efficient typing. In this layout, 70% of typing is done on the home row,
versus the QWERTY layout, where only 32% of typing is done there. In
theory, this layout might make the most sense, but QWERTY is so
ubiquitous, and adopting a new layout so hard, that the keyboard as we
know it will likely never change.
