Professor John S. Gero

Designing in most design disciplines involves visual reasoning. This research area is concerned with developing computational representations of visual images and computational models of visual reasoning in designing. The primary interest lies in qualitative representations and reasoning of two-dimenisonal and three-dimensional representations. This will allow us to develop computational tools that support visual reasoning and to increase the range of application of computational constructs in designing.

We have developed a model of visual emergence ("seeing" shapes or images that are not intentioanlly represented): this covers both emergence and supervenience. We have been able to show how different architectural styles can be measured from the drawings of their designs. We have been able to measure the informational differences in different representations of the same visual image.

Projects include;

qualitative representations of shapes

qualitative spatial representations

logic models of spatial reasoning

models of visual emergence

measuring information in visual representations

bond graph models of spaces and their use
