The keyboard remains the least economically designed computer device

Ergonomie devices are often designed to provide more comfort and to increase productivity but they can also help avoid pain and specific injuries. The ergonomic design of a computer keyboard needs expertise in ergonomics and biomechanics. The existence of a large category of typists with slow typing skills, visually searching the seemingly random keyboard, including novice users and the analysis of existing standards and keyboards leads to the conclusion that existing QWERTY based keyboards still remain the least ergonomically designed computer devices and need to be improved. This paper discusses the existing standards in ergonomics and the various commercial keyboards and makes observations about the ergonomic design features and the wrong recommendations of some standards.
