Keyboard and pointing device
TIPS
●
Switch hands
To give your pointing hand a break, you can periodically control your mouse or trackball with the
opposite hand (using the device's software to switch the button assignments).
●
Listen to your body
Let your body be your guide when you place your keyboard and pointing device. Your shoulders
should be relaxed, and your forearms, wrists, and hands should be in their neutral comfort zone.
Place your keyboard, mouse, and other input devices so that you can use them with your body in a
relaxed, comfortable position. In this way, you do not have to reach or shrug your shoulders while
working.
Positioning the keyboard
Position the keyboard directly in front of you to avoid twisting your neck and torso. This makes it possible
to type with your shoulders relaxed and your upper arms hanging comfortably.
Adjusting the keyboard height and slope
Your elbow height should be near the height of your keyboard's home row (refer to Shoulders and elbows
on page 12 section). Adjust your keyboard slope so that your forearms, wrists, and hands are in their
neutral comfort zone. Some find it most comfortable to set the keyboard slope to the lowest (most flat)
position, and to position their elbows slightly above the height of home row.
Aligning the mouse and keyboard
When using a mouse or detached trackball, position the device immediately to the right or left of your
keyboard and close to the keyboard's front edge. Avoid positioning the device too far from the side of
the keyboard or towards the keyboard's back edge, since these positions may cause you to markedly
bend your wrists out to the sides or reach too far (refer to
Pointing style on page 30 section).
You may also find it comfortable to position your mouse between your body and the keyboard's front
edge-in this case, your desk needs to be deep enough to position your monitor and keyboard back so
your forearms are fully supported on the work surface (refer to
Supporting your forearms
on page 21 section).
RIGHT
Position your pointing device immediately to the side of your keyboard and close to the keyboard's front
edge.
