Situation awareness (SA) is commonly described as the challenges encountered by an operator and it appears during the course of interaction with either the process itself or a human machine interface. Application and significance of SA is well established in different production sectors such as aviation, armed forces, and air traffic. The importance and significance of SA for Field Operators (F...

Situation awareness (SA) is a commonly used term to describe the challenges faced by human operators when interacting with controlled systems or work environments through technological interfaces. In this paper we conceptualize SA as judgment under uncertainty. As such, SA is conceived as the degree of correspondence between a set of human judgments and the distribution of true system or enviro...

OBJECTIVE This article summarizes two articles by Endsley on situation awareness (SA) and presents the influence of the concept on subsequent practice and theory of human factors. BACKGROUND In her articles, Endsley integrated and consolidated existing research done in the prior decade. METHOD I carefully examined and integrated subsequent articles on the SA topic written by Endsley and by ...

Although use of the term situational awareness (SA) assists researchers in creating more fruitful environments for pilots to operate in, its true potential as a psychological construct remains untapped until a valid means of a priori predicting SA becomes available. Shively, Brickner and Silbiger (1997) proposed a computational model of SA (CSA) that seeks to do just that, and the current line ...

  Background: An important factor in the prevention of industrial accidents is the ability of employees to maintain awareness of the work situation, understand the information it holds, and predict how situations will develop. In the present study, we examined the role of fatalistic beliefs and safety climate in predicting occupational situation awareness (SA) among workers.   Mate...

Ubicomp applications are characterized as situationaware, frequently-and-ephemerally-communicated and QoS-properties-associated. Using middleware to provide multiple QoS support for these ubicomp applications will enhance the development of the ubicomp applications. To satisfy the different QoS requirements of various applications in ubicomp environments, which are heterogeneous and resource-va...

We report a high-level architecture, CoJACK, that provides insights on behavior variability, situation awareness, and behavioral moderators. CoJACK combines Beliefs/Desires/Intentions (BDI) agents’ high-level knowledge representation and usability with several aspects of low level cognitive architectures, including processing time predictions, errors, and traceability. CoJACK explores new areas...

BACKGROUND Medical students may not be able to identify the essential elements of situational awareness (SA) necessary for clinical reasoning. Recent studies suggest that students have little insight into cognitive processing and SA in clinical scenarios. Objective Structured Clinical Examinations (OSCEs) could be used to assess certain elements of situational awareness. The purpose of this pap...

The level of Situation Awareness (SA) that systems and devices provide to individuals and teams is a critical factor that needs assessing throughout the design process. There are various methods available for assessing SA, yet there is little guidance available on which of these methods are the most valid, reliable and accurate. The purpose of this study was to compare three existing SA measure...

RATIONALE, AIMS AND OBJECTIVES Loss of situation awareness (SA) by health professionals during handover is a major threat to patient safety in perinatal care. SA refers to knowing what is going on around. Adequate handover communication and process may support situation assessment, a precursor of SA. This study describes current practices and opinions of perinatal handover to identify potential...
