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.
