Apple Laptop - Understanding Ergonomics
Here are some tips for
setting up a healthy work environment.
Keyboard
and Trackpad
When you use
the keyboard and trackpad, your shoulders should be relaxed.
Your upper
arm and forearm should form an angle that is slightly greater than
a right angle, with your wrist and hand in roughly a straight
line.
Use a light touch when typing or using the trackpad and keep your hands and fingers relaxed. Avoid rolling your thumbs under your palms.
Change hand positions often to avoid fatigue. Some computer users might develop discomfort in their hands, wrists, or arms after intensive work without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.
External
Mouse
If
you use an external mouse, position the mouse at the same height as
the keyboard and within a comfortable reach.
Chair
An
adjustable chair that provides firm, comfortable support is best.
Adjust the height of the chair so your thighs are horizontal and
your feet are flat on the floor. The back of the chair should
support your lower back (lumbar region). Follow the manufacturer’s
instructions for adjusting the backrest to fit your body
properly. You might have to
raise your chair so that your forearms and hands are at the proper
angle to the keyboard. If this makes it impossible to rest your
feet flat on the floor, you can use a footrest with adjustable
height and tilt to make up for any gap between the floor and your
feet. Or you can lower the desktop to eliminate the need for a
footrest. Another option is to use a desk with a keyboard tray
that’s lower than the regular work surface.
Built-in
Display
Adjust the
angle of the display to minimize glare and reflections from
overhead lights and windows. Do not force the display if you meet
resistance. The display is not meant to open past 130 degrees. You
can adjust the brightness of the screen when you take the computer
from one work location to another, or if the lighting in your work
area changes.
