Citizens’ observatories are emerging as a means to establish interaction and co-participation between citizens and authorities during both emergencies and the day-to-day management of fundamental resources. In this paper we present a case study in which a model of citizens’ observatories is being been translated into practice in the WeSenseIt project. The WeSenseIt citizens’ observatory provide...

The role of the Soldier is not as strictly defined today, as it was in World War II. In place of battlefields, the Soldier is placed in roles from peace keeper to combat Soldier in collapsed first world counties to impoverished third world nations. This fogs the understanding of situations and the role the Soldier is to play in them. Within these changing and dynamic times, a Soldier’s situatio...

Information overload is a severe problem for human operators of large-scale control systems, for instance, in road traffic management. In order to determine a complete and coherent view of the overall situation (i. e., gain situation awareness), an operator of such a system must consider various heterogeneous sources providing streams of information about a large number of real-world objects. S...

Pervasive computing systems use sensing, computing and communication capabilities to observe and respond to environmental phenomena. Such systems will eventually enable computers to seamlessly integrate into everyday life. They have many potential applications in the office, home, healthcare, gaming, environmental monitoring and public transportation. Healthcare is one of the most exciting exam...

(ABSTRACT) Situation (al) awareness (SA) is critical to analyze, predict and perform tasks effectively in a dynamic environment. Many studies on SA have ignored network dynamism and its effect on SA, focusing on simple environments. Many studies involving the network and SA have refrained from attempting to model information space dynamism (i.e. dynamic scenarios which may have more than one pr...

A computational model of attention and situation awareness (SA) was developed and used to predict pilot errors in the task of taxiing from runway to terminal. The model incorporates a lowlevel perception/attention module and a higher-level belief-updating module. Attentional scanning is controlled by bottom-up and top-down processes, with the effectiveness of top-down guidance varying as a func...

The use of radar and camera for situation awareness is gaining popularity in automotive safety applications. In this thesis situation awareness consists of accurate estimates of the ego vehicle’s motion, the position of the other vehicles and the road geometry. By fusing information from different types of sensors, such as radar, camera and inertial sensor, the accuracy and robustness of those ...

Organizations in the maritime safety and security domain have to cope with complex situations at sea, harbors, and rivers to maintain acceptable levels for safety and security. For safety, traffic rules apply at sea. Yet in areas with heavy traffic, it is difficult to tell which vessels adhere to traffic rules and which ones do not. For security, suspicious activities such as drugs smuggling ne...

Information overload is a severe problem for operators of large-scale control systems, as such systems typically provide a vast amount of information about a large number of real-world objects. Systems supporting situation awareness have recently gained attention as way to help operators to grasp the overall meaning of available information. To fulfill this task, data quality has to be ensured ...

Situation awareness is an essential cognitive-domain object of the command and control decision process. This paper places an organization’s SA in the context of OODA (Observe, Orient, Decide, Act) interaction between opposing teams. In addition, a hierarchical SA structure is used to organize SA generated from the physical entities in the corresponding physical domain. A rich Modal Logic-based...
