x
Chair
Use a chair that gives you
good back support.
Arms
Keep your forearms, wrists,
and hands in a relaxed and
neutral position. Don't
pound the keys; type with a
soft touch.
Thighs
Keep your thighs parallel to
the floor and your feet flat on
the floor or on a footrest.
What if I am traveling?
It may not be possible to observe the best ergonomic practices when
you are using the ThinkPad computer while on the move or in a
"casual" setting, such as the seashore or on a mountaintop.
Sometimes, your lap may be the only "desk" around. Regardless of
the setting, try to observe as many of the tips for proper usage as
possible. Sitting properly and using adequate lighting, for example,
will help you maintain desirable comfort and performance levels.
Questions about vision?
IBM's visual display screens are designed to meet the highest
standards and to provide you with clear, crisp images and large,
bright displays that are easy to see, yet easy on the eyes. Of
course, any concentrated and sustained visual activity can be tiring.
If you have questions on eye fatigue or visual discomfort, consult a
vision care specialist for advice.
Head
Keep your head in a
comfortable and vertical
position.
View
Maintain a comfortable
viewing distance of 20-30
inches.
Display
Position the display to avoid
glare or reflections from
overhead lighting or outside
sources of light.
Keep the display screen
clean and set the contrast
and brightness to levels that
allow you to see the screen
clearly.
