This book encourages further progress in user interface design in practical settings through examination of three themes: user interface projects that have achieved success in real life outside of the research lab; new methods in user interface design and evaluation; and the organizational context in which user interface design is done, and how design might be better accommodated to this context. The product of a workshop sponsored by the Institute of Cognitive Science at the University of Colorado and the Human-Computer Interaction Laboratory at the NASA Johnson Space Center, these chapters were contributed by invitation from leading user interface practitioners. They were then reviewed, edited, and organized into three corresponding parts for this book: * Success Cases: describes methods for designing and developing user interfaces for which there is convincing evidence of success. Evidence could include commercial sales, realistic test data, clear statements of user satisfaction, or other information that would be accepted by a prudent judge as indicating that the method actually worked. * Emerging Methods: describes new methods for designing and developing user interfaces that have the potential to significantly improve user interface design and development. * Real-World Context: discusses how work in user interface design and development accommodates or fails to accommodate real-world organizational, commercial , or practical requirements, and how this accommodation could be improved. An emphasis on practical design issues combined with broad coverage make this an excellent resource for the interface design professional and a useful text for advanced human-computer interaction courses.
