The concept of an isovist has had a long history in both architecture and geography, as well as mathematics. Tandy (1967) appears to have been the originator of the termìsovist'. He presents isovists as a method of``taking away from the [architectural or landscape] site a permanent record of what would otherwise be dependent on either memory or upon an(More)
We approach the design of ubiquitous computing systems in the urban environment as integral to urban design. To understand the city as a system encompassing physical and digital forms and their relationships with people's behaviours, we are developing, applying and refining methods of observing, recording , modelling and analysing the city, physically,(More)
In the literature on cognitive psychology, the issues raised by Gibson's ecological theory of perception (Gibson, 1979) have been examined and taken on board. Gibson's theory was formulated primarily in order to overturn theories laden with subjective and objective knowledge, and to replace them with a model in which the agent and its environment are(More)
Space syntax derives from a set of analytic measures of configuration that have been shown to correlate well with how people move through and use buildings and urban environments. Space syntax represents the open space of an environment in terms of the intervisibility of points in space. The measures are thus purely configurational, and take no account of(More)
In the past, human activities often resulted in mercury releases to the biosphere with little consideration of undesirable consequences for the health of humans and wildlife. This paper outlines the pathways through which humans and wildlife are exposed to mercury. Fish consumption is the major route of exposure to methylmercury. Humans can also receive(More)
Moving human-computer interaction off the desktop and into our cities requires new approaches to understanding people and technologies in the built environment. We approach the city as a system, with human, physical and digital components and behaviours. In creating effective and usable urban pervasive computing systems, we need to take into account the(More)
In this paper we present a sketch modelling system which we call Stilton. The program resembles a desktop VRML browser, allowing a user to navigate a 3D model in a perspective projection, or panoramic photographs, which the program maps onto the scene as a 'floor' and 'walls'. We place an imaginary 2D drawing plane in front of the user, and any geometric(More)
