Ergonomic Standards for Keyboards
-
Features
-
A keyboard slant that can be adjusted laterally, which makes the keyboard either higher or lower and in a flatter position, is preferred, notes the Cornell University Ergonomics Web. The best way to position yourself when using a keyboard is to keep your hands as flat and straight as possible, which is considered a neutral position.
Considerations
-
The angle of the keyboard relative to your wrist is very important. A keyboard that slopes upward from the front to the back requires that the user bend his hands upward, which results in wrist extension, and this leads to injury.
Options and Benefits
-
A split-angle keyboard may work better for some people, as can other alternative keyboard designs such as a completely split keyboard, adjustable-angle split keyboard or a vertically-split keyboard. An ergonomically correct keyboard will reduce upper body musculoskeletal involvement, improve your comfort, reduce stress on the arms and wrists and prevent injury.
