Chapter 2. 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 can also affect the way you arrange your workspace.
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. The backrest and
seat of your chair 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 comfortable position. Use a light touch on the keyboard and your hands and
fingers relaxed. Change the angle of the keyboard for maximum comfort by
adjusting the position of the keyboard feet.
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. 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 can adjust
the brightness and contrast controls on the monitor as the room lighting changes
throughout the day.
