What is ANTHROPOMETRICS ?
The study of the human body and its movements.

The study of the human body and its movement, often involving research into measurements relating to people. It also involves collecting statistics or measurements relevant to the human body, called Anthropometric Data. The data is usually displayed as 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 more comfortable to use. The application of measurements to products, in order to improve their human use, is called Ergonomics.
The diagram below shows, a table of anthropometric data (measurements) and how these are applied to the hand.

Ergonomics involves the study of people and their relationship with the environment around them. It often involves research into the way people interact with products and the environment. Anthropometrical data is used to determine the size, shape and/or form of a product, making it more comfortable for humans to use and easier to use. The ergonomics of a product is usually displayed as a drawing such as the one below.


Whatever you are designing, it must fit the person it is design for (usually called the customer / client). Adults and children come in all shapes and sizes. We all like or dislike colours, texture, sounds, tastes, flavours, forms and shapes. Consequently, when we design products, factors such as these should be kept in mind.

When designing a toy there are a number of points to consider. Children learn from sound, sight, colour, movement and other aspects. These all contribute to the ergonomics or anthropometrics of a design.

ERGONOMICS is mainly concerned with working out measurements, in order to improve the design of products.

 
For example: When designing a chair, one of the most important factors is comfort. This is linked closely to the seating height. Usually the seating height is calculated by measuring the most comfortable height for the person who is going to use the chair. If the chair is to be used by numerous people (such as in a Doctors waiting room), it is important to measure the comfortable seating height of a range of people and then work out the average height. The average seating height is then applied to the chair.
                                 WORKING OUT AVERAGE HAND WIDTH

In class you could do this by finding the average width of the right or left hand of ten 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, the examiner and teacher can see how you have worked out your measurements.
