In addition, use healthy work habits to maximize your performance and comfort when using your computer. 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. Appendix B. Accessibility and ergonomic information 85 Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to 30 inches).

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. What if you are traveling?

It might not be possible to observe the best ergonomic practices when you are using your computer while on the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as possible. Sitting properly and using adequate lighting, for example, helps you maintain desirable levels of comfort and performance. If your work area is not in an office setting, ensure to take special note of employing active sitting and taking work breaks.
