Much of how we construct meaning in the real world is qualitative rather than quantitative. We think and act in response to, and in dialogue with, qualities of phenomena, and relationships between them. Yet, quantification has become a default mode for information display, and for interfaces supporting decision-making and behaviour change. There are more opportunities within HCI for qualitative displays and interfaces, for information presentation, and an aid to help people explore their own thinking and relationships with ideas. Here we attempt one dimension of a tentative classification to support projects exploring opportunities for qualitative displays within design.
