Whenever possible, you should attempt to take account of the following ergonomic considerations:
•Position of your computer – Place the display directly in front of you . Keep your forearms horizontal, with your wrists in a neutral, comfortable position while using the keyboard, pointing device, or external mouse. Let your upper arms hang naturally at your sides. Have breaks during sessions with your computer. Excessive use of the computer may strain muscles or tendons.
•Furniture and posture – Sit in a chair with good back support. Adjust the level of the chair so your feet are flat on the floor. A footrest may make you more comfortable. Sit in a relaxed, upright posture and avoid slouching forward or leaning far backwards.
•Viewing angle of the display – Set the display at a confortable viewing distance. Make sure the display screen is at eye or slightly lower. Use the display tilting feature, if available, to find the best position. You can reduce eye strain and muscle fatigue by adjusting the tilt of the display to the proper position. Adjust the brightness setting of the display as well.
•
•Lighting – Choose a location where windows and lights do not create glare and reflection on the display. Use indirect lighting to avoid bright spots on the display. You can also purchase accessories for your display that help reduce glare. Proper lighting adds to your comfort and work effectiveness.
•Ventilation – Make sure you leave at least 5 cm of space behind and on each side of the main unit.
