Transcript of Ergonomics and anthropometrics

Ergonomics and anthropometrics
Lesson objectives/aims

At the end of the lesson, student should be able to :-
Describe scale and proportions related to architectural design.
Explain anthropometric and ergonomic related to architectural design.

As a architecture student you will need to understand the terms ergonomics and anthropometrics and the effect they have on the design of products.

Definition of Ergonomic
Ergonomics is derived from the Greek words ‘ergon’ (work) and ‘nomos’ (law). In America ergonomics is known as human factors.
Ergonomics is concerned with the way people interact with products, including how they feel, sound, smell and even taste


Designing to fit the body
Normal distribution often used to describe certain measures (depends on sample size)
Central Limit Theorem
There is no true average human

Use the following steps
Select measurements that relate to the design
Determine if design is to fit a certain percentile or a range
Combine values to ascertain compatibility
Determine if one design will fit all users

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

The keys on a computer keyboard are suitably sized and spaced for human fingers.

Door handles are placed at a comfortable height for adults

Sample 1 : Workstation

The handle must be an appropriate size for an adult hand.

The handle must allow a gap between the user’s knuckle and the side of the mug.

The diameter of the brim must be correctly sized for an adult’s face.

The rim of the mug must fit comfortably on the user’s lips.

The mug must not hold a weight of liquid greater than an adult can comfortably lift.

Sample 2 : A Mug

What are the ergonomic factors that affect the design of mobile phones?

Did you get?

How easily the user can read the display.

The distance between the keys.

The positioning of the earpiece.

How well it fits in the user’s hand.

The size of the keys.

How easily a call can be answered.

The volume of the ringer.

The brightness of the screen.

The positioning of the microphone.

The part of anthropology (study of humans) having to do with measurements of the human body to determine differences in races, individuals, etc…

Definition of Anthropometry

Anthropometry 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. (Chaffin, 1984)

‘Anthro’ means human + ‘Metrics’ means to measure = ANTROPOMETRIC


Reference planes
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
