Abstract. We present an evaluation of adding Focus+Context vs. Overview+Deatil features to a Zoom+Pan interface. The framework of the evaluation is an interface to deal with large sets of items with specific structural properties (sequential order, heterogeneous sizes), and behavior requirements (flexible interaction, maximizing screen space, minimizing changes in screen). The evaluation involved 43 participants. We studied the effect of three factors (namely, experience with the tasks, size of the sets, and tasks performed with the same set) on effectiveness, efficiency and user's satisfaction. The results show that experienced users of the interface enhanced with the Focus+Context features obtained the best results on effectiveness and efficiency. Furthermore, a satisfaction questionnaire showed that users felt more comfortable with the Focus+Context approach.
