1. Anthropometrics and Ergonomics
Anthropometric data is the study of human measurements such as dimensions and physical characteristics. It enables designers to make and design comfortable and safe products.
In my product I need to consider;
The age group (age 3 and under)
The strength of the person using it
Reach
Posture
Clearance
Designed using the range of 100% spectrum where 50% is the average sized person
Ergonomics is the relationship between a product and its user.
In this case the size of the product will need to be designed with the measurements of an average child’s hand under three so that the audiobook will be suitable to play with and therefore listen to without any discomfort to the consumer. 1

2. Anthropometric and Immediate Environment research
When designing the product I need to make sure that I am designing it to meet the needs of my targeted audience
There are many aspects that correlate to the human form that can enable my product to work effectively. Things that I need to consider are;
Colour – how my product will be recognised to the consumer
Shape – how the shape will effect the way that the consumer uses the product
Size – how big it needs to be in relation to the size of the human body and the iPod itself
Sound – the sound quality will have a detrimental impact on the tuning of the product and the way in which the docking station will play the music
The most important aspect to the human body will be the width of the hand and width of the little finger because this will effect the size of my product and how the consumer can hold it.
Stereotypes – can be useful designers. Not everyone is the same, however people can be put into different groups. Products can therefore be designed to equate to a specific group of people
The width of the hand will tell me how my design will need to be designed so that the iPod can be retracted from the position it is in when resting in the docking station
Anthropometrics – because designers use the 5th to 95th percentage the restrictions are taken within the most common feature of the product 2
