Keyboard and Trackpad

When you use the keyboard and trackpad, your shoulders should be relaxed. Your

upper arm and forearm should form an angle that is slightly greater than a right angle,

with your wrist and hand in roughly a straight line.

Last, but Not Least


Use a light touch when typing or using the trackpad and keep your hands and fingers

relaxed. Avoid rolling your thumbs under your palms.

Change hand positions often to avoid fatigue. Some computer users might develop

discomfort in their hands, wrists, or arms after intensive work without breaks. If you

begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult

a qualified health specialist.
