Abstract: Event debriefing systems and methods are provided for recording a plurality of datastreams related to an event. Each datastream includes chronological information related to at least one aspect of the event. An observer of the event may create time indication marks that facilitate recalling, during debriefing, what transpired at any particular point in time during the event. The recorded datastreams may be retrieved and presented beginning at marked time indications and continued chronologically thereafter in time synchronism.
