Dvorak keyboard

The Dvorak Simplified Keyboard (/ˈdvɔːræk, dəˈvɔː-/ d-VOR-ak) is a keyboard layout patented in 1936 by Dr. August Dvorak and his brother-in-law, Dr. William Dealey. Several modifications have since been designed by the team led by Dvorak or by ANSI. These variations have been collectively or individually called the Simplified Keyboard or American Simplified Keyboard, but they all have come to be commonly known as the Dvorak keyboard or Dvorak layout.

Dvorak proponents claim the layout requires less finger motion and reduces errors compared to the standard layout, the QWERTY keyboard. It is claimed that the reduction in finger distance traveled permits faster rates of typing while also reducing repetitive strain injuries, although that claim is controversial.

Although the Dvorak Simplified Keyboard (DSK) has failed to replace the standard QWERTY keyboard layout, most major modern operating systems (such as Windows,macOS, Linux, Android, Chrome OS, and BSD) allow a user to switch to the Dvorak layout. Neither iOS nor BlackBerry 10 provide a system-wide, touchscreen Dvorak keyboard, although third-party software is capable of adding the layout to both iOS and Blackberry 10.
