Microsoft Corporation 1069 Manuel D’Utilisation

To minimize reaching and to promote comfortable shoulder
and arm postures, try the following:
● Place your keyboard and mouse or trackball at the same height;
these should be at about elbow level. Your upper arms should fall
relaxed at your sides (see detail
3
).
● When typing, center your keyboard in front of you with your
mouse or trackball located close to it (see detail
4
).
● Place frequently used items comfortably within arm’s reach
(see detail
5
).
To promote proper wrist and finger postures, try the following:
● Keep your wrists straight while typing and while using a mouse
or trackball. Avoid bending your wrists up, down, or to the sides.
If your keyboard has legs, extend them if this helps you maintain
a comfortable and straight wrist position.
● Type with your hands and wrists floating above the keyboard, so
that you can use your whole arm to reach for distant keys instead
of stretching your fingers.
To minimize neck bending and twisting, try the following:
● Position the top of the screen near eye level (see detail
6
).
Bifocal wearers may need to lower the screen or talk to a qualified
health professional about glasses customized for computer work.
● Center your monitor in front of you. If you refer to your documents
more frequently than your monitor, consider placing your documents
directly in front of you and the monitor slightly to the side.
● Consider using a document holder to position your documents
near eye level.
To minimize eye strain, try the following:
● Position your monitor about an arm’s length away from you
when seated comfortably in front of it.
● Avoid glare by placing your monitor away from light sources
that produce glare, or use window blinds to control light levels.
● Remember to clean your screen. If you wear glasses, clean
them also.
● Adjust your monitor’s brightness and contrast.
● Adjust on-screen font sizes to make viewing more comfortable
● Adjust on-screen font sizes to make viewing more comfortable
for you, if your computer program has this feature.
