The widely used computer keyboard today comes from typewriter keyboards of yesterday. Christopher Latham Sholes invented the QWERTY keyboard for commercial typewriter in 1874. "QWERTY" stands for the first six letters in the top alphabet row. QWERTY keyboard was designed to prevent mechanical jams of typewriter and became popular as a standard layout.
Another keyboard layout are created to improve typing efficiency in 1936 by August Dvorak and William Dealey. Dvorak keyboard uses all high frequency of letters as home row: AOEUIDHTNS, so that the cumulative distance traveled by the 10 fingers are minimized.
This Demonstrations let you visualize letter frequency of sample text on QWERTY and Dvorak keyboard.
