1. memory
2. vision
3. hearing

Users can be classified into different categories.

Different design principles exist when the device is a touchscreen rather than a mouse or keyboard driven system.

Also important to consider is the age of the audience. Adults have different design needs to children.

Not all individuals are equally abled. Inclusive / Accessible Design takes this into account.

Other design principles are simply about applying common sense:

• The use of Consistancy between & within sites
