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)
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)
We outline initial investigations into how choices of spatial configuration, input devices and display technologies influence action and interaction in hybrid electronic and physical spaces. Joe Blogg is a socially situated public display for receiving MMS and SMS messages and we describe our first installation of this system, giving an account of the(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)
In this paper we explore the types of encounters that technology enables. We consider the differences between digital and non-digital encounters through two pilot studies carried out in the city of Bath, UK. We investigate how technology can be appropriated for shared interactions that support conscious (or unconscious) social encounters and highlight the(More)
Here we demonstrate the direct input to computer of a handdrawn perspective sketch to create a virtual environment. We either start with a photograph of a real environment or an existing VRML model, and then use a mouse or pen pad to sketch line drawings onto the scene. Visual clues and constraints from the existing background and line drawing, as well as(More)
Mixed Reality Architecture (MRA) supports distributed teams in their everyday work activities by linking multiple physical spaces across a shared three-dimensional virtual world. User configurable audio-visual connections give the inhabitants of MRA full control over whom they want to be in contact with and when they make themselves available, as well as(More)
