Ergonomics & Anthropometric Study
Transcript of Ergonomics & Anthropometric Study
ERGONOMICS & ANTHROPOMETRIC
VIDEO of ANTHROPOMETRIC & ERGONOMIC
Ergonomics is about '
the fit between people, the things they do, the objects they use and the environments they work, travel and play in.
student you will need to understand the terms ergonomics and anthropometric and the effect they have on the design of products.
One of the most important aspects of product design is considering
how the user will interact with the product; how comfortable will it be to use, sit on or wear?
How easy will it be to control an aspect of the product’s performance such as
temperature, volume, height, time, brightness or intensity?
DEFINITION OF ANTHROPOMETRIC
measurements of the human body
to determine differences in races, individuals, etc…
Anthropometric is a science that deals with the
measurement of size, weight, and proportions of the human body
. It is empirical (experimentally derived) in nature and has developed quantitative methods to measure various physical dimensions.
‘Anthro’ means HUMAN
‘Metrics’ means to MEASURE
can influence design
how to use dimensions
of the human body to evaluate the design
generate and analyse
a meaningful set of ordered data related to ergonomics
associated with ergonomics and anthropometry (the size and shape of humans)
Perform anthropometric measurements
as part of an ergonomics assessment
Designer need to makes sure that the products they design are the
right size for the user
and therefore comfortable to use
What's it all about?
DEFINITION OF ERGONOMICS
Ergonomics is the scientific discipline concerned with
designing according to the human needs,
and the profession that applies theory, principles, data and methods to design in order to
optimize human well-being
and overall system performance.

APPLICATION FOR ANTHROPOMETRIC
Used in ergonomics to specify physical dimensions of:
Equipment and tools
Car interior dimension
MEASUREMENT of ANTHROPOMETRIC
Taken between solid identifiable bony landmarks in standard anatomical positions
Anthropometric measuring kits
3-D body scanning (esp. for functional anthropometry)
Motion capture systems
Develop regression models with statistical relationships
TYPES of ANTROPOMETRICAL DATA
Measurements of the body dimensions taken with
the body in standard and still
(i.e. height of person, shoulder breadth, length of forearm)
Obtained when the body adopts
various working posture
, i.e. when the body segments move with respect to standard reference points in space (e.g. the area that can be reached by the right hand of a standing person defines a ‘standing reaching envelopes’ of the right hand, which provides critical information for work space design for right-handed standing workers)
USES of ANTHROPOMETRICAL DATA
To fit the task to the person
To avoid physical mismatches between dimensions of equipment and products and the corresponding user
To design for variability in people and not for the average
Does one size fit all
APPLYING ANTHROPOMETRICAL DATA
Determine the user population
Determine the relevant body dimensions
Determine the percentage of the population to be accommodated
Determine the percentile value of the selected anthropometric dimension
Make necessary design modification to the data from the anthropometric tables
Use mock-ups or simulators to test the design
IMPORTANCE of ANTHROPOMETRIC & ERGONOMIC
Allows designer to accommodate various percentiles of population so the majority of people can use and interact with the product or service being designed
Designer must aware of human factors, anthropometrics and ergonomic to ensure their product or service is safe and socially responsible (designing public places is especially sensitive to these conditions)
A toilet designed by a fashion designer
(fashion designer work to a fantasy of what the human body look like. They are taught how to draw human figures in a distorted, idealized way)
Design are based on these oddly proportioned, fantasy, body shapes.
A designer can use human factor, ergonomics & anthropometric to their advantage or these things may work against their design.
Good design observes these qualities first because no one wants to use or own a product or service which carries out the task poorly or dangerously
