Compact visualisation of multimedia interaction records

Abstract

We present an approach to building compact and effective information visualisation interfaces to allow users to browse and access content stored in continuous media. We introduce a content mapping framework, which supports time-based indexing of recordings of computer supported collaborative activity. In order to illustrate the temporal aspect of content mapping, we present HANMER, a system designed to provide fast access to audio-textual meeting recordings on personal digital assistants (PDAs). HANMER embodies techniques that exploit the processing capabilities and functionality of modern PDAs for visualisation and retrieval of multimedia meeting data.
