Keyboard And Pointing Device - HP Pavilion XT545 Supplementary Manual

Arranging Your Work Area
TIP
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.

Keyboard and Pointing Device

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
"Shoulders and Elbows"). 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 Chapter 4, in the section "Pointing
Style").
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
section "Supporting Your
(refer to Chapter 2, in the section
(refer to Chapter 3, in the
Forearms").
