DRS enables the synchronisation, replay, and analysis of audio and video recordings. Distinctively, DRS also enables these conventional forms of recording to be combined with ‘system logs’, which record interaction within computational environments or are the product of using computational techniques to analyse data. SMS messages, interaction in virtual environments, GPS data, or data from body sensors, for example, may be imported into DRS, synchronised with conventional recordings, and be replayed alongside them.
