Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the
surrounding light sources, active seating, and the placement of your computer hardware, can help you
improve your performance and achieve greater comfort.
This example shows someone in a conventional setting. Even when not in such a setting, you can follow
many of these tips. Develop good habits, and they will serve you well.
General posture: Make minor modifications in your working posture to deter the onset of discomfort caused
by long periods of working in the same position. Frequent short breaks from your work also help to prevent
minor discomfort associated with your working posture.
Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to
30 inches). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep
the display screen clean and set the brightness to levels that enable you to see the screen clearly. Press the
brightness control keys to adjust display brightness.
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to
best suit your comfort posture.
Arm and hand position: If available, use chair arm rests or an area on your working surface to provide
weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)
position. Type with a soft touch without pounding the keys.
Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
