The use of computer software as an aid to rugby, and sports coaching in
general, is well established. Videoed sport is the most widely used form of
raw data for sports analysis, though it is currently not being used to its
full potential. Patterns of player movement and position, both for
individuals and groupings of players, are important for understanding the
complexities of professional team sports.

This talk will outline a system that allows the specification and querying
of complex spatio-temporal patterns that index a video stream, and describe
various alternatives for representing these patterns.

A demonstration of prototype s/w developed as part of this research will
also be given.
