Situation Awareness: A Network Centric Approach
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 …

Toward a Model of Team Situation Awareness
<p>Situation Awareness (SA) is a construct that is considered important to safety in dynamic, risky, time-constrained and complex environments, such as military aviation, nuclear reactors and emergency management. Research consideration of SA is complicated by the fact that there is no clearly …

An Evaluation of RTA Symbols to Improve Pilot Situation Awareness
… Different displays were evaluated using situation awareness (SA) as a dependent measure. Participants were a mixture of non]pilots and pilots with an average flight time of 155 hours. All 24 participants were randomly assigned to their experimental condition. Objective SA data was …

Situation awareness approach to context-aware case-based decision support.
… Whilst these CBR approaches in context awareness address problems of incomplete data and domain specific problems, future problems that are situation-dependent cannot be anticipated due to lack of data by the CACBDSS to make predictions. Future problems can be predicted through situation …

Gender Difference in Situation Awareness when Receiving Wayfinding Direction by Landmarks and Headings
<p>In aviation, situation awareness (SA) is a fundamental requirement for effective flying and air traffic control. This skill has greatly been associated with pilot and air traffic controller performance. Previous studies in aviation and other fields have shown that gender differences exist in SA …
