AVOID!

HINT: 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 gripping or pinching your mouse tightly.

Using a Keyboard on a Sofa

J

AVOID!

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.

RIGHT!

Experiment with positioning pillows under your forearms; they may help keep your shoulders relaxed and your wrists straight.

HINT: Even on a sofa

Remember to properly support your lower back.

◆Avoid slouching.

◆Be sure not to recline too much; this may fatigue your neck and upper back.

◆Don't bend or angle your wrists.

◆Avoid sitting completely still and working without breaks for long periods.
