TITLE: | The Visual Representation of Information Structures: Perceptual Issues |
SPEAKER: | Colin Ware, University of New Brunswick |
The first part of this talk will describe an empirical study designed to address the issue of displaying graphs in 3D versus 2D perceptual space. The results suggest larger graphs can be understood if stereo and motion parallax depth cues are available.
The second part will review a broad range of perceptual factors that apply to the representation of information structures. This will cover pattern and object perception theory with particular attention paid to Biederman's geon theory.
Lastly we will discuss the possibility of using Michotte's work on the perception of causality in order to represent causal relationships using simple animations.
