Positioning your monitor
Place your monitor at a comfortable viewing distance, usually 50 to 60
centimeters away. Adjust the display in such a way that the top of the
screen is at or slightly below eye level.
Positioning your keyboard
The location of the keyboard is a very important factor to your
posture. Placing it too far away will make your body lean forward
forcing you to sit in an unnatural position. Placing it too high will add
tension to your shoulder muscles.
•
The keyboard should be placed just above your lap. Adjust the
keyboard height by flipping the folding stands located under the
keyboard.
• Keep your lower arms parallel to the floor as you type. Your upper
arms and shoulders should be relaxed. Then try typing with a light
touch. If you feel any shoulder or neck strain, stop for a while and
check your posture.
• Position your keyboard in front of your monitor. Putting your
keyboard beside your monitor will make you turn your head while
you type which could add tension to your neck muscles that may
later result in neck strain.
Positioning your mouse
• The mouse should be placed on the same surface as your keyboard
so that you can reach it with ease.
• Adjust its position to allow enough space for movement without
making you stretch or lean over.
• Use your arm to move the mouse. Do not rest your wrist on the
table when moving the mouse.
