Isovists and isovist fields are of interest to space syntax in that they offer a way of addressing the relationship between the viewer and their immediate spatial environment, however, in the form described by Benedikt (Benedikt, 1979) they are essentially non-syntactic. All the measures he proposes and then plots as fields are locally defined, and are independent of the state of the field in o...

While experiential qualities of rectangular architectural spaces can be effectively predicted from their proportions and area (Franz, von der Heyde, & Bülthoff, 2003), these factors obviously cannot be directly transferred on open-plan indoor spaces. We introduce an approach that relates experiential qualities of arbitrarily shaped architectural spaces to their spatial form using isovists (Bene...

This paper briefly describes the software application OmniVista written for the Apple Macintosh Platform. OmniVista is essentially an isovist generating application, which uses the 2d plan of a building or urban environment as input data, and then can be used in one of three modal ways. Firstly, point isovists can be generated by ‘clicking’ onto any location in the environment. Secondly, all na...

Recently, simulation agents (or animats) using an exosomatic visual architecture (EVA) have been shown to correlate well with observed pedestrian movement in both building and urban environments. An EVA uses a grid overlaid on a two-dimensional plan of a system to record the locations visible from the current grid square. The agents are allowed to roam freely in the environment, and lookup visu...

The space that can be seen from any vantage point is called an isovist and the set of such spaces forms a visual field whose extent defines different isovist fields based on different geometric properties. I suggest that our perceptions of moving within such fields might be related to these geometric properties. I begin with a formal representation of isovists and their fields, introducing simp...

This study addresses the interrelations between human wayfinding performance, the mental representation of routes, and the geometrical layout of path intersections. The virtual reality based empirical experiment consisted of a route learning and reproduction task and two choice reaction tasks measuring the acquired knowledge of route decision points. In order to relate the recorded behavioural ...

This short paper discusses some of the new functions available in UCL Depthmap 7. UCL Depthmap’s original purpose was to perform integration analysis of isovists just as the integration of axial lines could be calculated. It has now developed in a number of different directions, so it has become closer to a traditional GIS system with analysis functions for graphs built in. In doing so, it has ...
