In maritime surveillance, supporting operatorspsila situation awareness is a very important issue for enabling the possibility to detect anomalous behaviour. We present a user study which conceptualises knowledge to be implemented in a rule-based application aiming at supporting situation awareness. Participatory observations were used as a method for(More)
– A more precise definition of the field of information fusion can be of benefit to researchers within the field, who may use such a definition when motivating their own work and evaluating the contribution of others. Moreover, it can enable researchers and practitioners outside the field to more easily relate their own work to the field and more easily(More)
Keywords: Human–computer interaction Human factors Distributed cognition Maritime surveillance User-fusion User refinement a b s t r a c t Traditionally, the focus of most information fusion research has been on computational aspects, as illustrated by, for example, different versions of the JDL data fusion model. Consequently, the human user has mainly(More)
Information Fusion coordinates large-volume data processing machines to address user needs. Users expect a situational picture to extend their ability of sensing events, movements, and activities. Typically, data is collected and processed for object location (e.g. target identification) and movement (e.g. tracking); however, high-level reasoning or(More)
The aim of maritime surveillance systems is to detect threats early enough to take appropriate actions. We present the results of a study on maritime domain awareness performed during the fall of 2008. We analyze an identified capability gap of worldwide surveillance in the maritime domain, and report from a user workshop addressing the identified gap. We(More)
This study presents a literature analysis of 52 publications on the topic of information fusion performance evaluation. The aim is to identify whether information fusion researchers are aware of the problematic nature of performance evaluation in practice, which is substantially different from performance evaluation in test environments. As expected, only(More)
This paper reports on a brainstorming workshop with subject matter experts that aimed at identifying potential anomalies for world wide maritime surveillance. An extensive description of the workshop process and output is presented. The evaluation consists of two parts. First, the output of the workshop is compared with the output of a similar workshop as(More)
