The aim of the website is to provide you with an opportunity to learn about inter-
action design in ways that go "beyond the book." Additional in-depth material,
hands-on interactivities, a student's corner and informal tutorials will be provided.
Specific features planned include:
Hands-on interactivities, including designing a questionnaire, customizing a
set of heuristics, doing a usability analysis on 'real' data, and interactive tools
to support physical design.
Recent case studies.
Student's corner where you will be able to send in your designs, thoughts,
written articles which, if suitable, will be posted on the site at specified times
during the year.
Hints and guidance on the assignments outlined in the book.
Suggestions for additional material to be used in seminars, lab classes, and
lectures.
Key terms and concepts (with links to where to find out more about them).

Readership
This book will be useful to a wide range of readers with different needs and
aspirations.
Students from Computer Science, Software Engineering, Information Systems,
Psychology, Sociology, and related disciplines studying courses in Interaction De-

niques for designing and evaluating state-of-the-art products, and websites, as well
as traditional computer systems.
Web and Interaction Designers, and Usability Professionals will find plenty to
satisfy their need for immediate answers to problems as well as for building skills to
satisfy the demands of today's fast moving technical market.
Users, who want to understand why certain products can be used with ease
while others are unpredictable and frustrating, will take pleasure in discovering
that there is a discipline with practices that produce usable systems.
Researchers and developers who are interested in exploiting the potential of the
web, wireless, and collaborative technologies will find that, as well as offering guid-
ance, techniques, and much food for thought, a special effort has been made to in-
clude examples of state-of-the-art systems.
In the next section we recommend various routes through the text for different
kinds of readers.
