Whether you are designing an electric toaster or a shopping centre all the factors on this page will
be taken into account in your design and you should devote one or two pages in your folder to comment on these
human factors.
Health and Safety
There are health and safety issues with all electronic products. What would happen to your company if you designed
an electric drill that had electrical or mechanical faults when it was used? What if you designed a balcony for
a building with railings too short and someone fell off, who would be responsible. Or you design a chair that is uncomfortable
to sit in and it causes back problems. Follow these links to design failures.

Economic Factors (Cost)
If you build a kitchen with gold handles to all the units, either your company will go bankrupt or no one will be able
to afford to buy your kitchen design. Or what if you design a car with all the latest safety features, very light carbon
fibre pannels, titanium chassi, but again no one could afford to buy it. Or how about you make a dinning table out of
the cheapest materials you can find and two months later customers bring back what they have bought and ask for their
money back because one of the legs has fallen off?

The Human Environment
Your product will involve a user and a task such as a person writing a letter with a gel pen. It could involve much
more complicated physical considerations such as noise, illumination, and climate. An air conditioning system
that is too noisey, or a kitchen that is badly lit and damp could all lead to safety problems. Also consider the
vulnerability of human beings, your capabilities and limitations. What if you design a car that can travel so fast
that no one can control it. Or road signs that are too small to read. Doors in a cafe that open either
way. You could bump into someone on the other side.

Aesthetics (Taste)
What the product looks like. It considers a complete evaluation of all the phsical factors that a product is made
up of, colour, shape, form, sound. Psychologists try to turn aesthetics into a science, but it isnt. Aesthetics
is a quetion of personal taste in art, design, and music.

Ergonomics (Feel)
Physical factors primarily to do with the size of the human body and its relation of comfort to the made product.
Ergonomics is a science. It takes in to account individual human factors of height, weight, size, and
age, to make average models. So an average adult male weighs 90kg, therefore the lift that I have
designed can hold 8 persons (or 720kg) safely. Ergonomic factors take into account differences of height, weight,
size, and age between males and females, but dont work well with exceptions to the rules, an exceptionally heavy person,
or exceptionally tall person, etc..etc..
