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.
