An attractive and intuitive design of the human-computer interface is essential to the success of any computational system. Content-based image retrieval (CBIR) systems are inherently interactive. However, little attention has been paid to their interfaces. A major difficulty for designing the interface of these systems is to ally high quality means to integrate the querying on the images and the presentation and handling of the results. The goal of this paper was to analyze the user interaction in CBIR systems regarding their functionality and usability. This was achieved by following the actual interaction of users while working with a CBIR system. This task allowed us to suggest a questionnaire that can properly reflect the evaluated aspects of the users interaction regarding their satisfaction degree. This result can help on improving the development of new CBIR systems, which are a valuable tool in medical systems.
