This book provides a variety of answers in its description and discussion of new, sometimes radical approaches to 'usability evaluation', now an increasingly common business tool. It contains new thinking of the subject of usability evaluation in industry. Contributions come from those involved in the practice of industry-based usability evaluation as well as those involved in related research activity. The chapters are derived from and developed from presentations and discussions at the invited international seminar 'Usability Evaluation in Industry', and give a leading edge overview of current usability practice in industry - identifying those issues of concern and approaches to tackling these.
* Provides a comprehensive overview of current practice
* International examples
* Contains practical examples of ergonomics at work and gives clear ideas of what does and doesn't work under industrial constraints
