Situation awareness enables an intelligent agent to determine the meaning of perceived information in highly dynamic environments and to share the thereby discovered knowledge. Recently, ontology-based approaches to situation awareness have been proposed; some of them facilitate upper ontologies in order to provide a common vocabulary for collaborating agents and information sources. This paper...

To predict changes of situation awareness (SA) for pilot operating with different display interfaces and tasks, a qualitative analysis and quantitative calculation joint SA model was proposed. Based on the situational awareness model according to the attention allocation built previously, the pilot cognitive process for the situation elements was analyzed according to the ACT-R (Adaptive Contro...

Situation awareness depends on a reliable perception of the environment and comprehension of its semantic structures. In this respect, the cyberspace presents a unique challenge to the situation awareness of users and analysts, since it is a unique combination of human and machine elements, whose complex interactions occur in a global communication network. Accordingly, we outline the underpinn...

The use of technology to assist human decision making is not a novel idea. However, we argue that there is a need for a unified model which synthesizes and extends existing models. In this paper, we give two perspectives on situation analysis: a technological perspective and a human perspective. These two perspectives are merged into a unified situation analysis model for semi-automatic, automa...

In this paper, we propose the use of an ontology-based and semantic technologies approach to improving shared situation awareness amongst teams dealing with emergency situations. We have also identified that shared and team situation awareness tends to be viewed only in terms of cooperative task completion and so we have tried to describe their important relationship with team decision making. ...

Disasters pose severe challenges on emergency responders, who need to appropriately interpret the situational picture and take adequate actions in order to save human lives. Whereas Information Fusion (IF) systems have proven their capability of supporting human operators in rapidly gaining Situation Awareness (SAW) in control center domains, disaster management presents novel challenges: Due t...

Achieving situation recognition in ubiquitous sensor networks (USNs) is an important issue that has been poorly addressed by both the research and practitioner communities. This paper describes some steps taken to address this issue by effecting USN middleware intelligence using an emerging situation awareness (ESA) technology. We propose a situation recognition framework where temporal probabi...

Over the past two decades, machine learning has led to substantial changes in Data Fusion Systems throughout the world. One of the most important application areas for data fusion is situation awareness to support command and control. Situation Awareness is perception of elements in the environment, comprehension of the current situation, and projection of future status before decision making. ...

This paper offers insights to how cyber security analysts establish and maintain situation awareness of a large computer network. Through a series of interviews, observations, and a card sorting activity, we examined the questions analysts asked themselves during a network event. We present the results of our work as a taxonomy of cyber awareness questions that represents a mental model of situ...

Measuring Situation Awareness to evaluate an operator’s ability to handle complex dynamic situations and the use of assistance systems have become a standard approach in Human Factors research. Ideally, the operator’s work should be supported by enabling and disabling assistance systems depending on how well they are currently able to keep track of the situation. On the one hand, if the situati...
