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 to 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, touchpad, or external mouse. Let your upper arms hang naturally
at your sides. Have 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. 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.
❑
Viewing angle of the computer's display – Use the display's tilting feature to find the best position. You can reduce eye strain
and muscle fatigue by adjusting the tilt of the display to the proper position. Adjust the brightness setting of the display as well.
❑
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 also purchase accessories for your display that help reduce glare. Proper lighting
adds to your comfort and work effectiveness.
❑
Positioning 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 screen.
