Abstract

Designers often use previous knowledge during design activities. Case-Based Reasoning (CBR) systems have been used to help designers deal with a large repertoire of past design cases in many domains, like architecture and software. However, we still have little work that addresses Human-Computer Interaction (HCI) design in CBR systems. In general, they focus on specific HCI design artifacts, considering just a few aspects of HCI solutions. In this paper, we review related works to propose an enlarged conceptual model for HCI design cases in CBR systems. The model is flexible and extensible to accommodate different design artifacts, supporting different design processes and cultures. We have evaluated our conceptual model with a qualitative research, in which participants were asked to index and retrieve cases during an HCI design activity, referring to characteristics of context of use, domain, user, user goal, interaction, user interface, and system. The results indicate that CBR systems for HCI design should consider a wide view of the HCI problem and solution spaces, and the proposed conceptual model has great potential to support designers in dealing with a large repertoire of HCI design cases in CBR systems.
