What is User Logging

This chapter describes the design and use of multimedia technology for personal guides and public projections for two exhibitions on ancient and contemporary art. The authors discuss the critical issues, suggest approaches and solutions, and evaluate the results. In both exhibitions, the researchers designed personal guides on Apple iPod touch devices, with rich information structure and rich multimedia content. In one of the two exhibitions they also implemented a narrative path in the exhibition rooms with large displays and projections. They evaluated the guide design with questionnaires and automatic tracing of device use. This chapter reports the project outcomes.
