HINT: Split Keyboards
If you find it difficult to type with a straight, neutral wrist position, you may want to try a split keyboard.
Be aware, however, that improper set-up or posture while using a split keyboard can increase bending
in your wrists. So if you try one, set it up properly to align your forearms, wrists, and hands.
AVOID! Be sure not to rest your wrists on sharp edges.
Shoulders and
Adjust your chair height or keyboard height so that your shoulders are relaxed and
your elbows hang comfortably at your sides. Adjust your keyboard slope so that your
Elbows
wrists are straight.
Checking elbow height
Position your elbows in a zone that is near the height of your keyboard's home row
(the row that includes the letters G and H). This position allows you to relax your
shoulders. If you have long upper arms, you may find you need to position your
elbows slightly below the height of the home row to provide enough space under the
work surface for your knees and legs.

HINT: RELAX: Remember to relax, particularly in areas where muscle tension often builds up, such as
your shoulders.

Eyes

Working at your computer for long periods can be a visually demanding task and may
cause your eyes to become irritated and fatigued. Therefore, you should give special
attention to vision care, including the following recommendations:
Resting your eyes
Give your eyes frequent breaks. Periodically look away from the monitor and focus at
a distant point. This may also be a good time to stretch, breathe deeply, and relax.
Safety and Comfort
RIGHT!
Turn your chair to the side to help determine if your
elbow height is near the height of your keyboard's
home row.
