Safety and Comfort
WRONG!
Don't angle your wrist when using your
pointing device.

Pointing Comfort
When using a mouse or trackball, hold it loosely. Keep your hand relaxed, and click
the buttons using a light touch. When you are not using your pointing device, don’t
hold onto it; let it go.
Switch Hands
To give your hand a break, you may choose to control your mouse or trackball with
the opposite hand for a while.
AVOID!
Avoid gripping or pinching your mouse tightly.
Using a Keyboard on a Sofa
Even if you use your keyboard in a seemingly comfortable place such as a sofa,
bed, or your favorite lounge chair, you can still cause discomfort by sitting in an
awkward position or in one position for long periods. Remember to frequently
make changes to your position, within your comfort zone, and to take short breaks.
Aligning Forearms, Wrists, and Hands
When working on a keyboard on your lap, keep your forearms, wrists, and hands
comfortably aligned with each other in a straight, neutral line. Avoid bending or
angling your wrists. If your keyboard has palm rests, use them during pauses, not
while typing or using a pointing device.
