The Dvorak layout:
The Dvorak Simplified Keyboard is a keyboard layout which is one of the more common alternatives to the QWERTY layout. It has also been called the Simplified Keyboard or American Simplified Keyboard, but is commonly known as the Dvorak keyboard. It was designed by Drs. August Dvorak and William Dealey in the 1920s and 1930s. The two studied letter frequency and the physiology of the hand and created the layout to adhere to these principles:
The layout was completed in 1932 and was granted U.S. Patent No. 2,040,248 in 1936. It was designated an alternate standard keyboard layout by the American National Standards Institute (ANSI) in 1982. In 1984 the Dvorak keyboard had an estimated 100,000 users.
- It is easier to type letters alternating between hands.
- For maximum speed and efficiency, the most common letters and digraphs should be the easiest to type. This means that they should be on the home row, which is where the fingers rest.
- Likewise, the least common letters should be on the bottom row, which is the hardest row to reach.
- The right hand should do more of the typing, because most people are right-handed.
- It is more difficult to type digraphs with adjacent fingers than non-adjacent fingers.
- Stroking should generally move from the edges of the board to the center (as an example, rap your fingers on a table and see which is easier: going from pinkie finger to index or index to pinkie). This motion on a keyboard is called inboard stroke flow.
Even though many feel that the principles on which the Dvorak keyboard is based make it superior to the older QWERTY, all attempts to universally convert to the Dvorak have been met with resistance. Typists who are already proficient with the QWERTY layout do not want to have to relearn on a new keyboard. However, the design has made some headway, with Dvorak layouts now available on most major computer operating systems.
Dvorak also proposed an alternative ordering of the digitss on the numbers row, 7-5-3-1-9-0-2-4-6-8, believing this arrangement to be more efficient. However, few who use the keyboard employ this rearrangement, and indeed the ANSI standard calls for the usual numerical order.
There is considerable variation between implementations in the placement of punctuation.
