Keyboard layout significantly impacts typist fatigue. The standard keyboard layout has the keys Q-W-E-R-T-Y on the top row and is therefore referred to as QWERTY. The QWERTY layout appeared on the first commercially successful typewriter, invented by Christopher Sholes in the 1860s. It was designed to avoid key jams by causing successive keystrokes to occur on alternating sides of the keyboard. Unfortunately, this layout increased typist fatigue and slowed down typing. Even more unfortunately, despite advances made in keyboards and typewriters since the 19th century that have rendered the QWERTY layout unnecessary, no layout has yet displaced QWERTY as the standard keyboard layout.
Using an ergonomic keyboard layout can lead to dramatic increases in comfort and productivity.
