Working in Comfort
Setting Up Your HP Computing Equipment
Mice and Other Input Devices
Various aspects of using mice and other input devices may increase your
risk of discomfort or injury. Observing the following recommendations
may reduce that risk.
 As with the keyboard, try to keep your hand, wrist and forearm in a
neutral position while using your mouse or other input device.
 When using a stylus or light pen with a graphics tablet, don't grip the
stylus tightly. Keep your hand and fingers relaxed and try to main-
tain a neutral posture in your hand, wrist and forearm.
 If you use your thumb to rotate the ball on a trackball or spaceball,
keep it in a relaxed, natural shape, and maintain a neutral posture in
your hand, wrist and forearm.
 Hold the mouse gently by draping your fingers over it. Keep your
hand relaxed and fingers loose. Do not grip the mouse tightly.
 It takes very little pressure or force from your fingers to activate the
buttons or scroll wheel on your mouse, scrolling mouse, trackball or
other input device. Using too much force can place unnecessary
stress on the tendons and muscles in your hands, wrists and fore-
arms.
