User-Centered Approach for Adaptive Systems

This position paper proposes a user centered approach for the design and the evaluation of adaptive systems. A list of less common, but useful HCI techniques will be presented. After having introduced the peculiarities that characterize the evaluation of adaptive systems, the paper describes those evaluation methodologies following the temporal phases of evaluation, according to a user-centered approach. Three phases are distinguished: requirement phase, preliminary evaluation phase, final evaluation phase. For every phase, appropriate techniques are described by giving practical examples of their application in the adaptive web.
