A mobile system for non-linear access to time-based data

Conventional interfaces for visualisation of time-based media support access to sequential data in a linear fashion. We present two visualisation interfaces for a mobile application that supports non-linear, structured browsing of multimedia recordings by exploiting certain features of concurrent multimedia streams. The system is built on a content mapping framework which automatically creates links between text and audio data by establishing "temporal neighbourhoods". It illustrates how non-linear browsing may be particularly valuable for devices with limited screen real-estate.
