Ergonomics
What is ergonomics?

Ergonomics is the study of how humans
interact with their environment and the
products in them. It seeks to achieve the
most advantageous matches between
products, environments and systems and
the capacities, needs and inclinations of the
people who use them.

Ergonomics has three areas for
consideration.
1) Anthropometrics
2) Physiology
3) Psychology
Anthropometrics

The 5th- 95th Percentile.
The graph shows the
normal distribution curve
for a given number of
people against height.
Some people are tall,
others are short but the
majority of us fall within
the 5% to the 95th region
shown on the graph. The
graph can be repeated for
every body part.

There are three things to consider when
thinking about anthropometrics.

Physiology
An understanding of the human body’s capabilities is essential when
designing products in order to avoid stress, strain, fatigue and the
possibility of injury. Careful considferation must be given to factors as
diverse as strength, muscle control, posture, flexibilty joint movement and
reaction times.

Psychology

Mental and emotional triggers can stimulate
human behaviour. It is important to have an
understanding of how people receive,
perceive and process information in order to
design products which are appealing and
easy to use. The products we choose say
something about us but the reason we chose
them in the first place is because they have
appealed to our senses and triggered a
favourable response which we often
summarise by simply saying “I like that”.
