More about the Dvorak Keyboard Layout
Dvorak is a keyboard layout for English patented in 1936 by August Dvorak and his brother-in-law, William Dealey, as a faster and more ergonomic alternative to the QWERTY layout. Dvorak proponents claim that it requires less finger motion and as a result reduces errors, increases typing speed, reduces repetitive strain injuries, or is simply more comfortable than QWERTY.
Although Dvorak has failed to replace QWERTY, most major modern operating systems allow a user to switch to the Dvorak layout. iOS does not provide a system-wide, touchscreen Dvorak keyboard, although third-party software is capable of adding the layout to iOS, and the layout can be chosen for use with any hardware keyboard, regardless of printed characters on the keyboard.
Several modifications were designed by the team directed by Dvorak or by ANSI. These variations have been collectively or individually termed the Dvorak Simplified Keyboard, the American Simplified Keyboard or simply the Simplified Keyboard, but they all have come to be known commonly as the Dvorak keyboard or Dvorak layout.
