An Automated Method for Studying Interactive Systems
Berry de Bruijn, Robert C. Holte, Joel Martin · 1999
Information Retrieval experiments rarely examine more than a small number of user or system characteristics because of the limited availability of human subjects. In this article we present an interaction model, and based on that an experimental method. This automated method helps identify which user and system variables are relevant, which are independent of other variables, and which ranges of the variables are most important.
