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
