The Dvorak keyboard is a way of distributing the keys on a keyboard that was thought of by doctors August Dvorak and William Dealey in the 1920s and 1930s. It was born as an alternative to QWERTY, currently the most widely used layout. The Dvorak layout was patented in 1936.
To choose the location of the keys, doctors Dvorak and Dealey studied the frequencies of appearances of the letters in the texts and the physiology of the human hand.
- It is easier to type with alternating hands.
- For maximum speed and efficiency, the most common letters and digraphs should be the easiest to type. This means that they should be in the middle row, which is where the fingers rest.
- Also, the less common letters should be located in the bottom row, which is the most difficult to reach.
- The right hand should do most of the typing, since most people are right-handed.
- It is more difficult to type digraphs with adjacent fingers than with non-adjacent fingers.
- Keystrokes should generally move from the edges of the keyboard to the center (as an example, place your fingers on a table and see which is easier: go from little finger to index finger or vice versa). This movement on a keyboard is called inboard stroke flow.
Although it has spread throughout the world, it has not been able to dethrone QWERTY , because after studies, it was determined that there is no substantial advantage in writing speed when using this type of distribution.
