Mice and Other Input Devices

Various aspects of using mice and other input de

vices may increase your risk of

discomfort or injury. Observing the following recommendations may reduce that risk.

• Try to keep your hand, wrist, and forearm in a neutral position while using your

mouse or other i

nput device.

• If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a

relaxed, nat

ural 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 loos

e. Do not grip the mouse tightly.

• It takes very little pressure or force from your fingers to activate the buttons or

scroll wh

eel 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 forearms.

• If you are using a scrolling mouse, be sure to keep your fingers and hand in a

relaxed, ne

utral position when activating the scroll wheel. Also, this type of mouse

features software that can minimize the number of mouse movements or button

clicks.

• When using a mouse, trackball, or other input device, position it as close to the

keyboard a

s possible, and keep it at the same level as you do not have to stretch

while using it.

• Be sure to keep your mouse and trackball clean. Regular removal of accumulated

dust an

d dirt helps ensure proper tracking and reduces unnecessary hand and

wrist motions.
