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 …

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 …

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 …

Effects of Visibility and Alarm Modality on Workload, Trust in Automation, Situation Awareness, and Driver Performance
… perceived workload, system trust, and situation awareness (SA). Sixty-three undergraduate students from Old Dominion University participated in this study. Participants were asked to complete two simulated driving sessions along with Motion Sickness Susceptibility Questionnaire, …

The Role of Expertise, Working Memory Capacity, and Long -Term Memory Retrieval Structure in Situation Awareness
… memory and their roles in performing a flight situation awareness (SA) task. The major research question was whether the locus of individual differences in SA performance was the individual differences in capacity to maintain presented information in working memory or acquired skills to encode …

Investigating and Characterising the Impact of Vehicle Interfaces on Situation Awareness
… Driving Related Activity (DRA) performance. Situation Awareness (SA) is central to achieving multiple goals in a dynamic environment. This thesis investigates an Unconstrained approach to designing IVIS to examine how to improve multitasking performance in-vehicle through enhanced driver SA. …

Comparison of Augmented Reality Rearview and Radar Head-Up Displays for Increasing Spatial Awareness During Exoskeleton Operation
… mental workload on the user which may reduce situation awareness (SA) and increase risk of collision with pedestrians, negating the health and safety benefits of exoskeletons. Exoskeletons could be equipped with visual aids to improve SA, like rearview cameras or radar displays. However, …

Enhancing Situational Awareness Through Haptics Interaction In Virtual Environment Training Systmes
… for developing knowledge, skills and attitudes (KSA) within domains that have limited live training opportunities due to personnel safety and cost (e.g., live fire exercises). However, to ensure these VE training systems provide effective training and transfer, designers of such systems must …

The Effects of System Transparency and Reliability on Drivers' Perception and Performance Towards Intelligent Agents in Level 3 Automated Vehicles
… an important contributor to drivers' perception, situation awareness (SA), and driving performance. However, the effects of agent transparency on driver performance when the agent is unreliable have not been fully examined yet. The experiments in this Thesis focused on different aspects of IVIA's …

A Feasible Situation Awareness-Based Evaluation Framework for Quality of Machine Learning Explanations
… for industries with high sensitivity to safety, such as finance and medicine, explanations for the complexity of the models attract attention. A lack of methodology for in-context user need analysis and low-level evaluations of explanations appears to be the pain point for professionals …

Extended Situation Awareness Theory for Mobile Augmented Reality Interfaces to Support Navigation
… two studies, was used to extend current Situation Awareness (SA) theory and evaluate the application of an extended theory. These were achieved in the context of a reality-augmented environment for the task of exploring an unfamiliar urban context. The first study examined SA in terms of …

Takeover Required! Augmented Reality Head-Up Displays' Ability to Increase Driver Situation Awareness During Takeover Scenarios in Driving Automation Systems
… take control of the vehicle, if required. To safely take control, drivers must understand what is required of them and have situation awareness (SA) to understand important changes or factors within the environment around them. We can present drivers with needed takeover information using a …

Understanding the Effects of Sleep Deprivation on Executive Function, Complex Task Performance and Situation Awareness
Both sleep deprivation and loss of situation awareness (SA) have been cited as primary causal factors contributing to the accident and injury rate in the military and civilian sector (e.g., transportation). Despite the numerous references to both factors as causal in nature, much of the literature …

Investigating Pilot Performance Using Mixed-Modality Simulated Data Link
… data were gathered to evaluate workload, situation awareness, and subjective preference. Results indicated significant differences in pilot performance, mental workload, and situation awareness across the data link modalities and between flight conditions. Textual data link resulted in …

Profiling elite male squash performance using a situation awareness approach enabled by automated tracking technology
… pioneering research into squash performance by Sanderson and Way (1977) tested the hypothesis that “an individual exhibits a pattern of play which is relatively stable over time and independent of the opponent”. This belief influenced research in this area for many years. Many studies attempted …

A Novel Graphic Syntax: An investigation into how a GPS-enabled wayfinding interface can be designed to visually support urban recreational walkers’ situation awareness
… interfaces could be designed to visually support situation awarenessin use. That is, awareness of one’s embodied involvement in the surrounding environment while using the interface. The enquiry progresses through two phases. In the first phase, a programme of semi-structured interviews are …

Small Unmanned Aircraft Systems: Operator Workload and Situation Awareness Utilizing First Person View Techniques
… growth. However, the regulatory guidance for the safe integration of sUAS into the National Airspace System (NAS) has not kept pace with this technological growth within the market. Current regulatory limitations of line-of-sight operations may have an impact on the establishment of an equivalent …

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 …
