Dvorak keyboard the keyboard designed by August Dvorak in 1936, an efficiency fanatic, a professor of the University of Washington, and a cousin of Antonin Dvorak - the composer.
Dvorak arranged letters according to frequency, placed common letters on the home row and made the stronger fingers do most of the work. It significantly reduced fingers movement which is the reason for increased comfort and speed and diminishing RSI syndromes.
Rough typing rhythm is supported by placing vowels on the left hand home row and most common consonants on the right hand home row.
RSI syndromes - repetitive strain injuries.
