Suggestion for a visual dynamics analysis model using a natural movement model

The purpose of this study is to suggest a visual dynamics analysis (VDA) model that comprises a visibility analysis model integrated with a natural movement model. The theory of 'natural movement' from the background of Gibson's ecological theory of perception and Hillier's research could help to understand the relations between visual perception and movement. In a previous study, the natural movement model called the EVA (Exosomatic Visual Architecture) model was proposed by Turner and Penn with the concept of visual dynamics. However, the EVA model could not give any information about agent visual experience, but only a pattern of vision-driven agent movement. This is because spatial visual information already exists outside of the agent. Most of all, the model limits any visual dynamics analysis because the agents' movement patterns are irregular at a micro level. Therefore, in this study, a new natural movement model rule that shows good movement patterns at the micro scale is discussed, and visual indexes considering human visual characteristics and dynamic analysis are proposed. These are integrated with the VDA model and programmed with NetLogo. The analysis of test spaces by the VDA model and the meaning of the model are discussed.
