Joint Cognitive Systems
| Hi-index | 0.00 |
This paper reports first results of analyses concerning emergency response (ER) activity executed as a joint effort of three agencies: fire services, ambulance services and the police. The challenge to be tackled in the study is to understand the cognitive, operational and collaborative demands that characterize on-site responding to a complex emergency situation. The concept of Common Operational Picture (COP) is used to indicate one of the distributed cognitive functions of the multiagency ER personnel. The process of the adopted usage-driven design approach is described, and some central methodical solutions explained. Tentative results concerning the formation of COP indicate that a communication-oriented (semiotic) approach provides a possibility to empirically analyse the formation of COP and to understand the cognitive patterns that actors, environment and artefacts jointly form for tackling unanticipated and complex situations.
