“In HCI we have witnessed the rise and fall of conceptual modeling in general. The 1980s focused on changing human behavior, which was captured in models to inform designs. Around 1990 a second wave of HCI questioned the usefulness of this type of approach, pointing out how human behavior is contingent and situated, and that human beings actively work around whatever technical solutions exist. In more recent years, this has been supplemented with a focus on emotion and experience. More than ever, this research points away from conceptual modeling.”
