Ergonomics

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.

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 may 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.
