Creating a Comfortable Workspace
Many factors go into creating a comfortable work space, including proper
placement and adjustment of furniture and equipment, good lighting and
other environmental considerations.
In this section, we make some suggestions about how you can work
more comfortably. Keep in mind, however, that these are only suggestions.
Comfort is very personal, and only you can judge what works best for you.
Position of Keyboard and Input device
Try to place the keyboard and input device so that your arms and hands are
in a relaxed, comfortable and natural position. When the input device and
keyboard are correctly positioned:
• Your forearms should be parallel or almost parallel to the floor and your
wrists and hands should be in line with your forearms. Your wrist should not
be extremely flexed or extended.

Important: Computer User Health Information
In recent years, medical attention on occupational injuries has identified normal,
seemingly harmless activities as a potential cause of a wide range of problems
collectively known as Repetitive Stress Injuries (RSI) or Cumulative Trauma
Disorders (CTD). It is now recognized that any repetitive motion may contribute
to these health problems. As a computer user, you might also be at risk.
By paying attention to the way you perform your work, use your computer and
phone, play sports, and work around the house, you can identify the behaviors
that may be putting you at risk. If you experience pain, swelling, numbness, or
weakness in your wrists or hands (especially during sleep), see your physician
immediately. These symptoms could mean that you are developing a repetitive
stress injury that requires prompt medical attention. For more detailed informa-
tion, consult your doctor or a reputable book.
Using a Trackball
Most users find the best way to handle a trackball is by using the fingertips
to control the ball while using the thumb and pinky, or ring finger to click the
buttons. Try the following steps to find your most comfortable hand position.
1. Place your hand over the top of the Expert Mouse, with the heel of your
hand at its base or on the wrist rest.
2. Relax your wrist and fingers. Note where your fingers fall on the trackball
and which buttons are easiest to reach.
3. If you would like, reprogram the mouse buttons to best suit your
hand position.
