Appendix

101

•  When using the keyboard and touchpad, the shoulders 

should be relaxed. The upper arm and forearm should form an 
angle that is slightly greater than a right angle, with the wrist 
and hand in almost a straight line.

•  Use a light touch when typing or using the touchpad and 

keep the hands and fingers relaxed. Avoid rolling the thumbs 
under your palms or supporting the wrists on the desk while 
typing.

•  Use an external keyboard and mouse when using the 

computer for long periods. When using an external keyboard 
and mouse, position the devices at the same height as the 
computer and within comfortable reach.
