Dvorak studied letter frequencies and the physiology of people’s hands and created a layout to adhere to these principles: 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, and under the strongest fingers. 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 middle. An observation of this principle is that, for many people, when tapping fingers on a table, it is easier going from little finger to index than vice versa. This motion on a keyboard is called inboard stroke flow. The Dvorak keyboard layout became easier to access in the computer age. Currently, all major Operating Systems (such as Apple OS X, Microsoft Windows, GNU/Linux and BSD) ship with Dvorak keyboard layout in addition to the standard QWERTY layout. So far, DSK has failed to displace the QWERTY standard. What you're offered now is high-quality stickers, intended to simplify you work and enjoy it while doing it on computer.
