•
Avoid focusing your eyes on your screen for long periods
of time. Every 10 or 15 minutes, look around the room,
and try to focus on distant objects.
•
Where feasible, keep your head vertical while looking at
the screen. If you use an external keyboard, raise the
convertible notebook so the top of its screen is no higher
than eye level.
Setting up your computer desk and chair
When you are setting up your computer desk and chair, make
sure that the desk is the appropriate height and the chair helps
you maintain good posture.
•
Select a flat surface for your computer desk.
•
Adjust the height of the computer desk so your hands
and arms are positioned parallel to the floor when you
use the keyboard and touchpad. If the desk is not
adjustable or is too tall, consider using an adjustable
chair to control your arm’s height above the keyboard.
•
Use an adjustable chair that is comfortable, distributes
your weight evenly, and keeps your body relaxed.
•
Position your chair so the keyboard is at or slightly below
the level of your elbow. This position lets your shoulders
relax while you type.
•
Adjust the chair height, adjust the forward tilt of the seat,
or use a footrest to distribute your weight evenly on the
chair and relieve pressure on the back of your thighs.
•
Adjust the back of the chair so it supports the lower
curve of your spine. You can use a pillow or cushion to
provide extra back support.
Sitting at your convertible notebook
•
Avoid bending, arching, or angling your wrists. Make
sure that they are in a relaxed position when you type.
•
Do not slouch forward or lean far back. Sit with your back
straight so your knees, hips, and elbows form right
angles when you work.
•
Take breaks to stand and stretch your legs.
•
Avoid twisting your torso or neck.
