File talk:Computer Workstation Variables.jpg

This image is not appropriate. It is based on old guidelines that were often made up, stemming from World War II military. Although it depicts one of the postures that is generally considered acceptable (as is the forward sloping seat and reclined), but no posture is recommended and this posture will not work for many users. For example, what about people who need different viewing distances and there therefore monitor positions due to their farsightedness.

Further, these postures are controversial and not universally agreed on. Many researchers now reject some assumptions that are implicit in the image shown. And then of course, this picture implies that this is what ergonomics is about - when it's a small aspect of the field. It's not that this picture is so terrible (it's OK), but it's a terrible example of an image to represent the field. — Preceding unsigned comment added by Rani Lueder (talk • contribs)

Twisting the wrist
When working with normal keyboard and mouse, you twist your wrist, which is very bad for the nerves and muscles. For a workstation to be acceptable, you need to be able to put your wrists in neutral position when working with your mouse, and when typing. The best option available right now is a vertical mouse, and a vertical keyboard, as far as I know.

I definately recommend this picture to be removed from all articles. It is not ergonomically correct.
