Placement of the Keyboard, Mouse, and Other Input Devices
The keyboard, mouse, and other input devices, such as a numeric keypad, should be positioned
so that your arms and hands are in a relaxed, comfortable, and natural position.
• Select a work surface that is large enough to hold the computer equipment and any additional
items required for your work.
• Position the keyboard directly in front of you. This makes it possible to type with your
shoulders relaxed and your upper arms hanging freely at your sides.
• Position the mouse at the same level as the keyboard.
NOTE: If you are using a portable computer installed in a convenience base, it may be more com-
fortable to use an external keyboard, external mouse, or other input device.
Furniture and Posture
Adjust the furniture to meet your needs for comfort. If the workstation table is adjustable, move it
to the proper height. If it is not adjustable, then arrange the chair to suit your needs.
• Adjust the height of the chair and/or work surface so your forearms are parallel with the floor
and your wrists are straight.
• You should be able to maintain your proper arm position and place your feet flat on the floor.
Avoid pressure along the underside of your thigh near the knee and the back side of your
lower leg.
• Position the backrest and yourself so that your lower back is supported comfortably while you
sit at your workstation.
• Adopt a relaxed, upright working posture. Avoid slouching forward or leaning far backward.
• Place frequently used work materials within easy reach.
