Motivation interaction with information visualization: process of exploration (Andrienko & Andrienko 2005) concept of insight (North 2006) – insight is: complex, deep, qualitative, unexpected, relevant Gestalt psychology: concept of insight holistic theory of perception and reasoning similarity between perception and reasoning
Gestalt psychology – reasoning (Mayer 1995) insight as completing a schema problem is a coherent set of information with a gap, solution is to fill this gap in a way to complete this structure insight as reorganizing visual information insight occurs when a problem solver literally looks at a problem situation in a new way insight as reformulation of a problem insight occurs when a problem solver mentally redefines and clarifies the problem insight as removing mental blocks reliance on inappropriate past experience insight as finding a problem analog using the structural organization of one situation to understand a new problem
Recent models (Davidson 2008) Selective encoding when people identify important elements of information previously seen as irrelevant supported e.g. by highlighting Selective combination individuals discover an appropriate framework for previously unrelated facts Selective comparison relationship between present problem and previous experience is found analogy Training problem solvers in these activities improves insights.
Research framework Do users of information visualization tools engage in such activities? How can we identify such activites? Can we motivate users with appropriate design to engage in these activities?
