Applying Ergonomics
Your computer is a portable device and can be used in a variety of environments.
Whenever possible, you should apply the following ergonomic considerations:
❑ Position of your computer — Place the computer directly in front of you as
you work. Keep your forearms horizontal, with your wrists in a neutral,
comfortable position while using the keyboard, touch pad, or external
mouse. Let your upper arms hang naturally at your sides. Take breaks during
sessions with your computer. Excessive use of the computer may strain
muscles or tendons.
❑ Furniture and posture — Sit in a chair with good back support and
armrests. 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 backward.
❑ Viewing angle of the computer’s display — Tilt the display to find the best
viewing angle. Also try adjusting the brightness setting of the display.
Following these suggestions can reduce eye strain and muscle fatigue.
❑ Lighting — Choose a location where windows and lights do not create glare
or reflection on the display. Use indirect lighting to avoid bright spots on the
display. You can purchase accessories for your display that help reduce
glare. Proper lighting adds to your comfort and work effectiveness.
❑ Placement of an external display — When using an external display, set
the display at a comfortable viewing distance. Make sure the display screen
is at eye level or slightly lower when you are sitting in front of the monitor.
