The Usability Stack: Reconsidering Usability Criteria regarding Knowledge-Based Systems
نویسندگان
چکیده
Considering usability-based design and evaluation, many general guidelines and heuristics have been proposed in the past. Yet there is still a lack of tailored criteria for the specific case of knowledge-based systems. In this paper we propose the Usability Stack for knowledge-based systems as a new model that summarizes and classifies usability criteria for that particular context. The model as a whole, as well as the different layers in particular, are discussed. We also shortly describe the results of exemplarily going through one knowledge system, developed by our department, according to the model.
