Ergonomics
How do we take decisions when designing ?
Physical Ergonomics, matching the body
Design of the physical aspects of a system to fit with the physical parameters
of the human body
Example height of the working space to allow both men
and women to wash the dishes
Mental ergonomics, matching the mind
Design of the interactive aspects of a system to fit with the mental parameters
of the human mind
What people expect, how they organise their work
Spiritual Ergonomics, matching the heart
Design of all aspects of a system to fit with the spiritual parameters of
the human mind
How to deal with the mood, the colour of the background
etc
The Airplane emergency procedure
The size, the way to find it, the way to not think about it
