Situationsmedvetenhet i en simulerad värld : användandet av SAGAT-metoden i en simulator - / Situation Awareness in a simulated world : The use of SAGAT in a simulator -Kjellin, Andreas January 2003 (has links)
<p>Detta experiment hade två syften, dels att undersöka skillnader i situationsmedvetenhet och prestation mellan officerare och studenter i en simulerad värld, dels undersöka hur två olika sätt att mäta situationsmedvetenheten samvarierar. Simulatorn som användes var det kommersiella spele t"Delta Force 2" där ett eget scenario byggdes. För att mäta situationsmedvetenheten användes två metoder, SAGAT-metoden och Cooper-Harper- metoden. SAGAT-metoden innebär att man bryter simuleringen och försökspersonen får svara på frågor som rör var de är, vad som händer och vad som kommer att hända. Denna metod mäter situationsmedvetenheten objektivt till skillnad från Cooper-Harper som mäter situationsmedvetenheten subjektivt, försökspersonen får efter experimentets slut skatta sin egen uppfattade situationsmedvetenhet. </p><p>De resultat som experimentet gav var att det existerade en signifikant skillnad i prestation mellan officerare och studenter, i avseende på deras sätt att röra sig i terrängen och undvika upptäckt, men inga övriga signifikanta skillnader kan visas upp. </p><p>Resultatet från undersökningen visar också på att SAGAT-metoden inte är lämpad för denna typ av markstridsuppgifter.</p>

Adaptation and Validation of the Situation Awareness Global Assessment Technique for Student Registered Nurse AnesthetistsDishman, Deniz 01 January 2019 (has links)
Anesthesia is a health care specialty fraught with high workload demands, stressful work environments, increased production pressure, work areas with many distractions, an increasing use of advanced technology, and the constant need to prioritize work actions. Effective clinical judgment in this dynamic environment necessitates that the provider demonstrate the ability to project what may occur secondary to actual or potential condition changes. These key elements operationalize situation awareness (SA).
High level SA is an important characteristic for the successful development of student registered nurse anesthetists (SRNAs). With Endsley’s “Theory of Situation Awareness” as the foundation, the goal of this study was to adapt and validate the “Situation Awareness Global Assessment Technique” (SAGAT), to quantify SRNAs' SA during a specific simulated anesthesia event.
With IRB approval, purposeful sampling identified a group of CRNA, nurse educator subjects and an exploratory sequential mixed methods design utilized. Delphi methods during qualitative data collection and validation used a seven-member sample. Content analysis resulted in items for the adapted SAGAT. Quantitative methods utilized data collected from a second 40-member sample yielding item content validity and scale content validity indices (S-CVI/Ave. 0.92). Additionally, exploratory factor analysis provided further reliability with a Cronbach’s alpha of 0.937.
Findings revealed that a SAGAT specific to the anesthesia domain and the SRNA subgroup was amenable to adaptation and validation, providing positive implications in SRNA education and training. Additionally, results support the further adaptation, validation, and use of this instrument in other anesthetic content areas, as well as other health care domains.

Evaluating Multi-Uav System with Text to Spech for Sitational Awarness and WorkloadLindgren, Viktor January 2021 (has links)
With improvements to miniaturization technologies, the ratio between operators required per UAV has become increasingly smaller at the cost of increased workload. Workload is an important factor to consider when designing the multi-UAV systems of tomorrow as too much workload may decrease an operator's performance. This study proposes the use of text to speech combined with an emphasis on a single screen design as a way of improving situational awareness and perceived workload. A controlled experiment consisting of 18 participants was conducted inside a simulator. Their situational awareness and perceived workload was measured using SAGAT and NASA-TLX respectively. The results show that the use of text to speech lead to a decrease in situational awareness for all elements inside the graphical user interface that were not directly handled by a text to speech event. All of the NASA-TLX measurements showed an improvement in perceived workload except for physical demand. Overall an improvement of perceived workload was observed when text to speech was in use.

Measuring a Platoon Commander's Performance in a Complex, Dynamic and Information Rich Environment / Mätning av en Plutonchefs Prestation i en Komplex, Dynamisk och Informationsrik MiljöMelbi, Alexander January 2021 (has links)
Command and control (C2) environments are complex, dynamic and rich in information. Thus, measuring the performance of an agent in a C2-system, in this case a platoon commander, poses a challenging task for the researcher. To measure the performance of a platoon commander in this thesis, the OODA loop is used as a model for representing the four processes in which the platoon commander is engaged in during a military C2 mission. In accordance with these processes, performance measurements for the platoon commander are identified. The relevance of the performance measurements, to the C2 tasks and goals of the platoon commander, are tested through three studies conducted in a simulated warfare scenario, and two workshops, one with a platoon commander and one with two scientists. As a result of the studies and workshops, an assessment tool for measuring the C2 tasks and goals of the platoon commander, is developed. This assessment tool consists of modified versions of the Crew Awareness Rating Scale (CARS), the Situation Awareness Global Assessment Technique (SAGAT) and the NASA-Task Load Index (NASA-TLX), as well as generic performance measurements measuring fratricide, deaths and completion of overarching goal.
