Ergonomic information
Working in the virtual office might mean adapting to frequent changes in your environment. Following some
simple rules will make things easier and bring you the maximum benefits of your computer. Keeping in mind
such basics as good lighting and proper seating, for example, 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
corresponding hotkeys on the keyboard to adjust display brightness.
Head position
Keep your head and neck in a comfortable and neutral (vertical or upright) position.
