frequent breaks. Look up periodically and focus on an
object that is further away. This will give the muscles
in your eyes a chance to relax.
Positioning the keyboard
• Make sure the keyboard height is comfortable for
typing.
• When you type, the keyboard should be positioned so
that your arms are relaxed and comfortable, and your
forearms are roughly horizontal. Your shoulders
should be relaxed and not hunched up.
• Type with a light touch, keeping your hands and
fingers relaxed. Your wrists should also be straight.
• If your computer came with a wristrest and you
choose to use it, do not rest your hands on the
wristrest or desktop while you are typing. Instead,
use the wristrest only when resting. If you prefer not
to use the wristrest, you may remove it and use the
keyboard without it.
Positioning the mouse
• Position your mouse on the same surface as your
keyboard so that they are at the same level. Allow
enough space so that you can use your mouse
without stretching or leaning over.
• When you use the mouse, hold it lightly with all your
fingers and click gently. Move the mouse with your
entire arm instead of only using your wrist.
