When an adverse event escalates into a criminal investigation, it becomes very difficult to control and combine information into a manageable format. The PROBE project addresses this problem by developing two generations of working prototypes capable of undergoing live field tests and evaluation by a wide-ranging community of CBRNE (Chemical, Biological, Radiological, Nuclear, Explosives) responders. The paper reports the derivation of preliminary user requirements for PROBE based on interviews and observations of a large-scale simulated CBRNE exercise. Five Human-Computer Interaction (HCI) researchers shadowed specialists representing different responder agencies (Emergency Medical Services, police, hazardous materials expert) during the three-hour exercise. Relying on cognitive ethnography, a variant of the concept of distributed cognition, video and audio recordings were merged with notes taken during the exercise and used to derive the preliminary user requirements. The study showed that these could be extracted from a relatively small set of behaviors and different types of utterances made by the active participants in the exercise. The paper concludes with a take-away message for researchers wishing to observe CBRNE exercises in which the command post event management team is collocated.
