While you are sitting at a desk, the best position for your
head, neck and upper body is to be facing your work. If you
sit in a twisted posture or look down at your work your muscles
become tense and sore. The most effective arrangement of reference
documents and screen is to have them as close together as
possible.
Use a document
holder. Make sure it is stable and
big enough for the documents you use.
A good place for documents is just below your screen
(angled up towards you).
If this isn't possible use the following layouts:
If you look mostly at the screen while you are
working, have the screen in front of you with your
documents just to one side.
If you look mostly at your documents while you
are working, have these in front of you with your
screen just to one side.
