Human Factors in
Design & Engineering
Human Factors Engineering
• It is the study of designing equipment and
devices that fit the human body and its
cognitive abilities.
• The two terms "human factors" and
"ergonomics" are essentially synonymous.
• is a multidisciplinary field incorporating
contributions from psychology, engineering,
industrial design, graphic design, statistics,
operations research and anthropometry.
A good design should
always consider the human
user.
Erogonomics
Greek word “ergo” which means human
Greek word “nomics: which means natural
law
Question Time
Should the designer/ engineer design the product
(or solution) for the average person?
Statistical Impact
• Gaussian Distribution
Statistical Impact
• Designer must select the “optimal
match”
• Design for the target population
• Typical from the 5th to the 95th
percentile.
Who is it designed
for?
• Hyundai Veloster
Who is it designed
for?
• Child’s laptop
Universal
Design
The design of a product, system, or
environment that reduces barriers and
assists not just the special needs
population but all individuals.
Universal Design Principles
•
•
•
•
Equitable – useful to wide range of people
Flexible – adaptable design for wide range
Simple – easy to use regardless of person
Perceptible – understandable regardless of
persons sensory ability
Universal Design Principles
• Tolerance – minimizes risks
• Low Physical effort – use with minimum
fatigue
• Size & Shape – adaptability
• Ability One Design Challenge

Discussion
Point
Give an example of
A
Universal Design
Failure
Anthropometry
Anthropometry
is the science
that defines
physical
measures of a
person’s size,
form, and
functional
capacities.
OSHA & NIOSH Applications
• As applied to occupational injury
prevention, anthropometric
measurements are used to evaluate the
interaction of workers with tasks, tools,
machines, vehicles, and personal
protective equipment, especially in
regard to determining degree of
protection afforded against hazardous
exposures, whether chronic or acute.
Product Development
• What factors should
be considered in
designing this work
station?
• How do you make the
station compatible for
a variety of body
types and sizes?
