HFE Human Factors Exam Questions
with 100% Correct Answers | Latest
Update
Human Factors - ✔✔Human factors is the study of interactions among
humans and parts of a system.
What are the consequences of not addressing Human Factors Engineering
in the design, development, operation and maintenance of systems? -
✔✔Increased costs, chance of injury, damage of environment. Decrease in
safety, production. Bad posture.
Briefly identify the major components of a typical human-machine system. -
✔✔The major components of a typical human-machine system are:
displays, perceived information, information processing and decision
making, motor responses for control activation, controls, and internal
status.

,Human Factors is often referred to as multidisciplinary, explain what this
means. - ✔✔A multidisciplinary approach is when a group of people with
different professional specializations work together towards a problem.
What is compatibility? - ✔✔Compatibility deals with relationships between
controls and displays, and how it affects the ease to which people can use
from several alternatives. The goal is for the relationships to be consistent
with human expectations.
What potential benefits can be achieved when incorporating compatibility
into a system? - ✔✔Benefits
o Learning is faster
o Reaction time is faster
o Less errors are made
o User satisfaction is higher
o Increase productivity
o Increase profits
o Increase human safety
How are compatibility relationships established? - ✔✔• Some are inherent
in the design/situation, such as a steering wheel must be turned to the right
to move to the right

, • Some are inherent to the degree they have similar spatial relationships,
such as a knob under a display controls that display
• Some are culturally acquired, such as to turn the light on in the U.S. you
push up and in Europe you push down
Your class text describes a number of different methods that can be used
to add "coding" to make the controls easier to distinguish. Describe three
coding methods and for each describe how adding the coding method you
choose makes it easier/safer for the human operator to use the control. -
✔✔• Coding By Location
o Some locations of controls have been standardized, making it easier for
the user when purchasing something that they have used before
o Adding coding by location can increase response time, safety,
productivity, and efficiency
o Such examples are location of controls in vehicles and location of
surgical tools for surgeons
• Coding By Size
o Size coding can be used to distinguish between different controls
o This could be used in the design of pilot aircraft controls
o The pilot should distinguish controls and what they do by their small,
medium, large sized controls during a stressful situation
