Low level of driver’s situation awareness (SA) and high level of cognitive load are considered as reasons of vehicle accidents. Cognitive load is higher when driving abroad because of unfamiliarity with differences in international traffic rules or vehicle configurations. This paper aims to objectively assess the driver’s SA when performing lane changing tasks under unfamiliar driving condition...

Introduction The Situation Awareness Global Assessment Technique (SAGAT), is a global tool developed to assess SA across all of its elements based on a comprehensive assessment of operator SA requirements (Endsley, 1987b; 1988b; 1990c). Using SAGAT, a simulation employing a system of interest is frozen at randomly selected times and operators are queried as to their perceptions of the situation...

One of the main causes of accidents in safety-critical systems is human error. In order to reduce human errors in the process of handling abnormal situations that are highly complex and mentally taxing activities, operators need to be supported, from a cognitive perspective, in order to reduce their workload, stress, and the consequent error rate. Of the various cognitive activities, a correct ...

This paper proposes a new concept, Situation Analysis (SA), in an attempt to merge into a unifying synthesis the main notions put forward by well established data fusion and situation awareness models. In addition to clarifying the original concepts of these models, this synthesis expands on some of these ideas while achieving a fair depth in the level of details and the rigorousness of the res...

Existing information systems often lack support to crisis and emergency situations. In such scenarios, the involved actors often engage in ad hoc collaborations necessary to understand and respond to the emerging events. We propose a collaboration model and a prototype aiming to improve the consistency and effectiveness of emergent work activities. Our approach defends the requirement to constr...

Effective monitoring and accurate detection of potential disease outbreaks is critically dependent upon the situation awareness (SA) of health professionals. Quick and precise identification of an outbreak is needed to prevent the disease from spreading. Biosurveillance systems that focus on supporting SA may help improve the ability of health professionals to detect outbreaks and make decision...

(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...

The objective of this research was to assess the effectiveness of adaptive automation (AA) for supporting information processing (IP) in a complex, dynamic control task by defining a measure of situation awareness (SA) sensitive to differences in the forms of automation. The task was an air traffic control (ATC)-related simulation and was developed to present four different modes of automation ...

Cars have had various forms of Driver Support Systems (DSS) for considerably longer than they have taken to have an overt driver interface or to otherwise assume the outward appearance of a ‘computer’. Existing forms of DSS, such as power steering, engine management and anti-lock brakes, combined with a more general trend in ubiquitous computing and increased refinement, are isomorphic with fut...

In this study, air traffic control instructors controlled simulated traffic while three techniques for determining situation awareness (SA) were implemented. SA was assessed using a self-report measure (SART); a query method that removed information on the plan-view display (SAGAT); a query technique that did not have a memory component (SPAM); and the detection of errors integrated into the sc...
