Chapter 1. Arranging your workspace

To get the most from your computer, arrange both the equipment you use and

your work area to suit your needs and the kind of work you do. Your comfort is of

foremost importance, but light sources, air circulation, and the location of electrical

outlets also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few

guidelines to help you find a position that suits you best.

Sitting in the same position for a long time can cause fatigue. A good chair can

make a big difference. The backrest and seat should adjust independently and

provide good support. The seat should have a curved front to relieve pressure on

the thighs. Adjust the seat so that your thighs are parallel to the floor and your

feet are either flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor and your wrists

in a neutral, comfortable position. Try to keep a light touch on the keyboard and

your hands and fingers relaxed. You can change the angle of the keyboard for

maximum comfort by adjusting the position of the keyboard feet.

Height

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place

the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to 24 in.),

and position it so you can view it without having to twist your body. Also position

other equipment you use regularly, such as the telephone or a mouse, within easy

reach.

Glare and lighting

Position the monitor to minimize glare and reflections from overhead lights,

windows, and other light sources. Even reflected light from shiny surfaces can

cause annoying reflections on your monitor screen. Place the monitor at right

angles to windows and other light sources, when possible. Reduce overhead

lighting, if necessary, by turning off lights or using lower wattage bulbs. If you

install the monitor near a window, use curtains or blinds to block the sunlight. You

might have to adjust the brightness and contrast controls on the monitor as the

room lighting changes throughout the day.
