G3a. TOUCH TYPISTS can raise the monitor so that the visible screen top is just below eye level. Any document holder should be at screen height and in the same focal plane to minimise head twisting and tilting. COPY TYPISTS may prefer the screen to one side and the document holder directly in front of the head/neck and upper body. Provided it does not cause reflection problems, the monitor may also be tipped back slightly.
B3. If the monitor is set too low there is a tendency to work with the head tilted downwards putting strain on the neck and upper back. The whole body may also lean forward, moving away from the support of the chair back and encouraging slouching.
