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, keep your forearms parallel to the 
floor and relax your shoulders and upper arms. Your 
elbows should form a 90 degree angle.
•
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.
