Visualization

Abstract

Visual focus and mental focus in diagram-based problem solving have been shown to be often interrelated with respect to cognitive and visuo-perceptual representational and procedural properties. A problem solver's visual focus can be used for a rough detection of mental focus in diagrammatic reasoning – sufficient to distinguish certain problem solving modes. An integration of visual focus over time can reveal characteristic patterns of problem solving strategies or solutions models. Such patterns hold formidable potential for computer-assisted and collaborative human-computer reasoning with diagrams.
