Designing and using integrated data collection and analysis tools: challenges and considerations

Abstract This paper describes the design and evolution of mi integrated set of computer-aided usability engineering (CAUSE) tools for data collection and analysis. The tools were designed to collect and analyse observational, video, and system event data in both the usability laboratory and in the field. Three generations of tools are described and the problems with each generation are discussed. Solutions to the problems arc presented, where available. Conclusions about the strengths and weaknesses of particular types of data, CAUSE tool design, and the importance of multiple data sources are drawn. An agenda for future work is also outlined.
