Work Surfaces The height of the desk should be about elbow level when sitting down. Check that there is enough room below the work surface to comfortably fit your knees and thighs. Arms should be bealy perpendicular to the floow with wrist nearly straight. When using the mouse, move the mouse with your arm and not just your wrist. Choose a mouse that fits the size of your hands comfortably and is as flat as possible to minimize wrist strain.
Placement of Monitor Correct placement of monitor screen can help prevent eye strain, neck pain and shoulder fatigue as it keeps your head and neck as straight as possible. If possible, place the monitor screen about one arm’s length away with the top of the screen at eye level so that you can see clearly without having to look up.
Keyboard Keep your fingers relaxed while typing and using a mouse. Use a soft touch on the keyboard instead of pounding keys with unnecessary force. Avoid holding a pen or anything else in your hands while you type.
