JohnnyVon is an implementation of self-replicating machines in continuous two-dimensional space. Two types of particles drift about in a virtual liquid. The particles are automata with discrete internal states but continuous external relationships. Their internal states are governed by finite state machines but their external relationships are gove...

This demonstration reports on the current stage of development of a web-based environment to support video sharing and annotation. The initial requirements and their implementation are briefly presented. The application is aimed at supporting the professional development of teachers with a multimedia application over a broadband network. However, w...

Spatial Cognition brings together psychology, computer science, linguistics and geography, discussing how people think about space (our internal cognitive maps and spatial perception) and how we communicate about space, for instance giving route directions or using spatial metaphors. The technological applications adding dynamism to the area includ...

This paper describes a project currently being undertaken at the National Research Council. The project addresses itself to two much-discussed topics: • the relation between the semantics of language and vision • the notion of symbol-grounding. We discuss some of the parallels and differences between the linguistic and visual channels of percept...
