Display
Arrange the display so that the top of the screen is slightly below your eye level when
you’re sitting at the keyboard. The best distance from your eyes to the screen is up to
you, although most people seem to prefer 18 to 28 inches (45 to 70 cm). Position the
display to minimize glare and reflections on the screen from overhead lights and
windows.
Mouse
Position the mouse at the same height as your keyboard and within comfortable reach.
Keyboard
When you use the keyboard, your shoulders should be relaxed. Your upper arm and
forearm should form an angle that is slightly greater than a right angle, with your wrist
and hand in roughly a straight line.
Use a light touch when typing and keep your hands and fingers relaxed. Avoid rolling
your thumbs under your palms.
Change hand positions often to avoid fatigue. Some computer users may develop
discomfort in their hands, wrists, or arms after intensive work without breaks. If you
begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a
qualified health specialist.
