(4) You're right; all of these answers are important reasons why man's
information processing limitations and capabilities must be recognized.
Problems often arise, however, when man's abilities are viewed in the
light of 'absolute maximum performance levels' when designing the man
component into a system.
By focusing on these maximum standards, no
flexibility is designed into the system to account for various environmental
or job-related variables that can reduce this level of performance.
For instance, in terms of visual performance, glare (caused by direct
or reflected light that is much greater than what the eyes can adapt to) can
seriously detract from successful completion of the task. Thus, such visual
factors need to be taken into account when designing a system.
Now, can you remember a good example of how human factors specialists
take glare into account when designing equipment?
(1) Red goggles are often used to block out the glare and allow the eyes to
stay dark adapted. Turn to Page 77.
(2) Glare shields are often designed into the system to block glare and
maintain visibility. Turn to Page 58.
(3) Both glare shield and sunglasses are good examples of the input the
human factors specialist has in system design. Turn to Page 53.
to cut down on the amount of glare encountered. Turn to Page 97.

(2) Good, but not complete.
That might be helpful for identifying any
effects of RVs, but it's not the answer here. Return to Page 47.
