 * **Characteristics** of good user product interfaces:

Simplicity, well organised and easy to use.

Intuitive.

Easy access.

Low memory burden.

Designers have to think about the frequency of use, functionality and possible learning problems in using the interfaces that they are responsible for designing. || ||

**__Paper prototyping. __**
//Prototypes //can be used to help get potential users opinions of an interface BEFORE it goes into production. Using users in this way is called participatory design.
 * [[image:paper_prototype.jpg width="238" height="261"]] || To help designers get their designs just right they can involve users in the development of an idea.

Paper prototyping is a cheap and easy way to test out ideas, it also helps minimise lead time in the development of a product. Feedback can be given by the designer, expalining what happens when the user uses the prototype in a certain way. ||
