Ergonomic Considerations
Ergonomic Considerations
You will be using your computer as a portable device in a variety of environments. Whenever possible, you should attempt
to take account of the following ergonomic considerations for both stationary and portable environments:
❑ Position of your computer – Place the computer directly in front of you (1). Keep your forearms horizontal (2), with your
wrists in a neutral, comfortable position (3) while using the keyboard or the pointing device. Let your upper arms hang
naturally at your sides. Take frequent breaks while using your computer. Excessive use of the computer may strain eyes,
muscles, or tendons.
❑ Furniture and posture – Sit in a chair with good back support. Adjust the level of the chair so your feet are flat on the
floor. A footrest may make you more comfortable. Sit in a relaxed, upright posture and avoid slouching forward or leaning
far backwards.
