Preface
goals: This guide is aimed at students who want to develop new products, services, software or websites. We cover the whole interaction design process in a brief and understandable way and enable students to understand the most important terms so that they can read the literature.
No-Goals: Include material that is non-relevant for practical work.
Foundations
Iterative Design Process
Usability Goals
The usability goals are a small collection of basic user needs. They are broad, but you will have no trouble to understand them.
Utility
If your product's functionality matches the needs of your users and enables them to reach their goals it has a good utility.
You can find out your users needs and goals by doing "user research" which means that you apply some research methods. One of these methods is doing a special kind of interview with some users. I will cover this technique in a latter chapter.
Learnability
A good learnability exists if the users you target can use your product without putting a lot of effort learing. This is especially important for the very basic functions.
Ideally users don't have to bother about new concepts and unknown terms.
Learnability is what will be the first thing that comes into your mind if you think about interaction design. Paradoxically it is a principle that is ignored in many products: Industry often uses a lot of functions that dimish learnability and many student projects ignore learnablity and focus on efficiency.
