Definition of Ergonomics in Books: As I have mentioned in my
previous hub, ergonomics is the
study of behavior and activities of people adapting systems and
workstations to the needs of
users. Ergonomics works in different areas such as biomechanics,
environmental, cognitive,
etc. The word ergonomics is obtained from the Greek words
"ergos" which means work and
"nomos," which means laws, for this literally means "labor
laws". We can say that ergonomics
is a multidisciplinary activity responsible for the conduct and
activities with the aim of bringingthe products, systems, jobs and
environments, characteristics, limitations and needs, looking
to optimize their effectiveness, workplace safety, and workplace
comfort at one place.
Definition of Anthropometry What is Anthropometry? How
anthropometry is related to
Ergonomics?
Definition of Anthropometry: Anthropometry is one of the areas
that support ergonomics and
deals with the human body measurements that refer to body size,
strength, shape, and work
capacity.
Ergonomics Relationship with Anthropometry: In ergonomics,
anthropometric data are used to
design workspaces, safety equipment and personal protection
tools considering the
differences between the characteristics, abilities, and physical
limits of any particular human
body.
The dimensions of the human body have been a recurring theme
throughout the history of
mankind, a widely known example is the drawing by Leonardo da
Vinci, where the figure of a
man is confined inside a square and a circle, where trying to
describe the proportions of the
human being is "perfect." However, due to the differences
between the proportions and
dimensions of human beings, it is not possible to find an
accurate model to describe the size
and proportions of humans. Anthropometric studies have been made
relating to a specific
population, as can be male or female, and in different age
ranges.
As discussed before in my previous articles or hubs, the scope
of ergonomics is very broad
and all the classifications and branches of ergonomics cannot be
discussed in such small
space and less amount of time and also listing all of them
together can be very confusing, so I
will discuss other branches and sub-branches of ergonomic in my
upcoming hubs. This was all
about ergonomics and anthropometry.

hat is ANTHROPOMETRICS ? The study of the human body and its
movements.
e study of the human body and its movement, often involving
research into measurements relating to people. It also in
lecting statistics or measurements relevant to the human body,
called Anthropometric Data. The data is usually displa
a table of results, diagram or graph. Anthropometric data is
used by designers and architects.
What is ERGONOMICS ?
The study of people and their relationship with the environment
around them.
Measurements, also known as anthropometric data, are collected
and applied to designs / products, to make them mo
mfortable to use. The application of measurements to products,
in order to improve their human use, is called Ergono
onomics involves the study of people and their relationship with
the environment around them. It often involves reo the way people
interact with products and the environment. Anthropometrical data
is used to determine the size,
d/or form of a product, making it more comfortable for humans to
use and easier to use. The ergonomics of a prod

texture, sounds, tastes, flavours, forms and shapes. Consequen

mind.
en designing a toy there are a number of points to consider.
Children learn from sound, sight, colour, movement and oects. These
all contribute to the ergonomics or anthropometrics of a
design.
GONOMICS is mainly concerned with working out measurements, in
order to improve the design of products.
example: When designing a chair, one of the most important
factors is comfort. This is linked closely to the seating h
ually the seating height is calculated by measuring the most
comfortable height for the person who is going to use the he chair
is to be used by numerous people (such as in a Doctors waiting
room), it is important to measure the comforta
ting height of a range of people and then work out the average
height. The average seating height is then applied to the

In class you could do this by finding the average width of the
right or left hand often pupils and dividing the total
by ten (called the mean average). This can be drawn on a design
sheet as a table of figures (see below). In this way,
examiner and teacher can see how you have worked out your
measurements.HOW TO LAYOUT AN ERGONOMICS RESEARCH SHEET
onomics is an important part of research. Whatever you design it
must fit the person who is to use it. For example, if y
to design a door handle you may need to collect statistics
regarding the size of hands. If you are designing a chair you

example below, the statistics have been worked out for thrage size
of adult hand. The measurements will then help in the development
of a design for a desk tidy/ organiser as
rall hand sizes will determine the overall size of the desk tidy
and its compartments.
Carefully consider the measurements that need collecting for
your project. When designing a book shelf the averageching height
of an adult will need to be determined. When designing a watch

At the top of the page, clearly explain the measurements you are
to collect.Draw simple diagrams to represent the measurements you
are to collect and label the dimensions - A, B, C etc... (see

Collect the measurements of at least ten people and complete the
table of statistics.Work out the average (mean average). This is
achieved by calculating the total and dividing by the number of

wer is the average measurement.
Do not collect too many measurements. The example opposite has
room for four columns of statistics although only twe been
used.
Add notes and labels to the diagrams if you feel an explanation
is necessary.
At the bottom of the ergonomics page state clearly how you
intend to use the statistic you have collected.The same guidance
applies to collecting statistics about animals. For instance, if
you are designing an automatic anima
