Abstract:

Due to economic and operational constraints, there is an increasing demand from aviation operators and training manufacturers to extract maximum training usage from the lower fidelity suite of flight simulators. It is possible to augment low-fidelity flight simulators to achieve equivalent performance compared to high-fidelity setups but at reduced cost and greater mobility. In particular for visual manoeuvres, the virtual reality technique of head-tracking amplification for virtual view control enables full field-of-regard access even with limited field-of-view displays. This research quantified the effects of this technique on piloting performance, workload and simulator sickness by applying it to a fixed-base, low-fidelity, low-cost flight simulator. In two separate simulator trials, participants had to land a simulated aircraft from a visual traffic circuit pattern whilst scanning for airborne traffic. Initially, a single augmented display was compared to the common triple display setup in front of the pilot. Starting from the base leg, pilots exhibited tighter turns closer to the desired ground track and were more actively conducting visual scans using the augmented display. This was followed up by a second experiment to quantify the scalability of augmentation towards larger displays and field of views. Task complexity was increased by starting the traffic pattern from the downwind leg. Triple displays in front of the pilot yielded the best compromise delivering flight performance and traffic detection scores just below the triple projectors but without an increase in track deviations and the pilots were also less prone to simulator sickness symptoms. This research demonstrated that head augmentation yields clear benefits of quick user adaptation, low-cost, ease of systems integration, together with the capability to negate the impact of display sizes yet without incurring significant penalties in workload and incurring simulator sickness. The impact of this research is that it facilitates future flight training solutions using this augmentation technique to meet budgetary and mobility requirements. This enables deployment of simulators in large numbers to deliver expanded mission rehearsal previously unattainable within this class of low-fidelity simulators, and with no restrictions for transfer to other training media.

Abstract:

This work focuses on the type-3 self-driving cars, partially autonomous vehicles which can control themselves for most of the time and may ask the driver to take control of the car in case of specific situations. The purpose of this study is to evaluate the perception of the simulated risk faced by the participants in a low fidelity simulation in relation with their background: the gaming and driving experience. The participants of the study drove in the simulator and answered a questionnaire about both the driving session and the background information. The simulated risk was assessed and compared with the information from the questionnaire. It was evaluated both the performance of each participant represented by the level of risk experienced while driving the simulation and the correct identification of the risk faced. The result data highlighted a positive correlation between the driving performance and the videogame experience.

Abstract:

Användandet av simulatorer i utbildningar ökar mer och mer. Simulatorer har använts inom pilotutbildningar och inom medicinsk utbildning länge och det finns mycket forskning som stödjer deras effektivitet. Nu har simulatorerna blivit mer tillgängliga i och med den tekniska utvecklingen och har börjat användas för förarutbildningar. Däremot saknas samma gedigna vetenskapliga stöd som finns för pilotutbildningar och medicinsk utbildning. Det finns visst underlag för utbildning i riskmedvetenhet men inte så många andra färdigheter. Syftet med studien var att undersöka hur effektiv en simulator är vid utbildning av förare i Eco-driving. Till studien rekryterades 20 elever från Yrkesakademin som utbildas för behörighet C, tung lastbil. Studien var av mellangruppsdesign där experimentgruppen tränade Eco-drivingfärdigheter och data över bränsleförbrukning och hastighet samlades in. Kontrollgruppen fick en teoretisk utbildning i Eco-driving i form av en inspelad video. Experimentgruppen hade en signifikant förbättring av bränsleförbrukning men inte kontrollgruppen. Detta stödjer effektiviteten av simulatorbaserad utbildning av Eco-driving. Resultaten är även uppmuntrande till träning av liknande färdigheter som bland annat är av betydelse för trafiksäkerhet. Dessutom finns det goda möjligheter att minska kostnaderna vid förarutbildningar samtidigt som eleverna lär sig bättre.
The use of of simulators in education is increasing. The aviation and medical education have a long history of implementing simulator training and education. With a strong body of scientific research that validates their use in education. As the technical development has increased, the availability of affordable simulators has increased their use in driver education. Unfortunately the research is not as strong as with the aviation or medical education. There are some support that simulator-based education can improve hazard perception but not so many other skills. Therefore I want to examine the effectiveness of a simulator in teaching Eco-driving skills to drivers. 20 students from Yrkesakademin were recruited as they were learning to drive trucks. The study is of between group design where the experimental group practiced Eco-driving skills in the simulator. Data were collected of the participants fuel consumption and speed. The control group were shown a video lecture on Eco-driving. The experimental group did significant improve while the control group did not. These results support the effectiveness of simulator-based education of Eco-driving skills. It also is encouraging for similar driving skills that can have a significant effect on traffic safety. While there is encouraging evidence for reducing the cost of driver education at the same time the students learning is enhanced.

Abstract:

The bus industry is plagued by high accident costs and risks of passenger injuries. A bus simulator may offer a method of reducing accident rates by delivering targeted training to bus drivers who are most at risk. The first part of this thesis describes the design of the UK's first bus simulator, the fidelity of which was based on a thorough analysis of bus crashes. The second part describes the first studies in a multi-staged method to evaluate the training effectiveness of the simulator: face validity, effects of bus driver experience and stress on simulated performance and simulator sickness. This approach ensured that the ABS has a reasonable level of fidelity, is capable of eliciting behaviourally valid responses from bus drivers and is the first step is achieving training transfer effectiveness. The final study investigated the occurrence of self-bias in bus drivers. The conclusions drove the design of simulated scenarios to be used for bus driver training.

Abstract:

In this world of fast-paced learning, training agencies often require their learners to acquire the knowledge and skills needed for a job at an expedited rate. Because of this rapid form of training, learners are sometimes uncertain about their abilities to execute task-based performances. This uncertainty can lead to a decrease in learners’ self-efficacy on expected task performance. In order to help with this training, trainers are using a variety of simulations and simulators to provide learners’ valuable and necessary training experiences. This mixed methods study explored the influence of high-fidelity virtual training simulators on learners’ self-efficacy. It used pre- and post-simulation-use surveys that combined general self-efficacy questions (Schwarzer & Jerusalem, 1995) and task-specific self-efficacy questions (Bandura, 1977, 1997, 2006; Bandura, Adams, Hardy, & Howells, 1980). This study had a sample size of 18 participants. It was assumed that the intent of providing learners with the vital experience needed to perform specific tasks in a high-fidelity virtual training simulator was to increase their self-efficacy on task-specific criteria. Instead, through surveys, observations, and interviews, the research revealed a decrease in learners’ self-efficacy due to heightened emotional arousal stemming from the learners’ experiences with the level of realism the simulator provide, as well as with breakdowns within the simulator. The breakdowns and the realism were the most influential aspects that influenced self-efficacy in this study. The significance of these findings shows that despite learners wanting to use high-fidelity virtual training simulators, improperly functioning simulators can negatively influence learners’ self-efficacy in task-based performances.

Abstract:

This study investigated the link between age and gender susceptibility to simulator-induced sickness in conjunction with display type. Simulator-induced sickness and ataxia were measured before and after exposure to a medium-fidelity driving simulator. Participants in four age and gender categories (older and younger males and females) operated the simulator with a consumer-grade head-mounted display (HMD), and then with a large screen, direct-view plasma display.

This study set out to recommend a particular display type that would be appropriate for use with particular age/gender groups in a general-purpose driving simulator. Unfortunately, practice effects affected the simulator-induced sickness and driving performance results for display type, which precludes making recommendations regarding the appropriate use of each display. Despite this, several important discoveries were made, including: 1) older participants did experience significantly increased simulator-induced sickness discomfort than the younger participants - regardless of display type; and 2) there was no significant difference found between genders in either simulator-induced sickness or driving performance; although females generally expressed a subjective preference for the direct-view display.

Display type was not found to affect the degree of ataxia experienced by participants; however, this study did find that although older participants exhibited significantly higher rates of simulator-induced sickness discomfort than the younger participants, they recovered their postural equilibrium significantly faster. This indicates that the older participants had greater difficulty adapting to the simulation environment than younger persons. It also suggests that younger persons are at greater risk during immediate post-simulation activities such as driving. Although it is likely that this effect would disappear over time, it has implications for agencies such as the Department of Motor Vehicles or drivers education schools that are considering the use of a driving simulator device before an on-road skills test.

Abstract:

Research has shown that head-mounted displays can produce greater presence in a virtual environment than direct-view displays. It has also been shown that after vision, haptic response is one of the most important inputs for humans in a simulated environment. This research was designed primarily to determine the performance differences associated with different display types, levels of steering force feedback, and the interaction between these two factors in a low-to-medium fidelity, PC-based driving simulator. Participants drove on a simulated driving course during which both objective driving performance data were collected (lane deviation, speed control, steering wheel angle variance, and time to the complete course) as well as subjective self-report measures including questionnaires designed to tap immersive tendencies and perceived levels of presence. Results of the research show that the use of a head-mounted display can significantly impact driving performance in terms of speed control and lane deviation. Speed control was significantly improved (increased) and lane deviation was significantly improved (decreased) in three of the four roadway segments with the use of an HMD. Results for active steering force feedback, however, showed a significantly negative effect on driving performance with an increase in average lane deviation. Descriptive statistics showed that participants preferred the HMD and D-V equally and all but one participant preferred active steering force feedback.

Abstract:

Empathetic communication enhances the nurse-patient relationship and improves patient outcomes and needs to be taught and evaluated during simulated clinical experiences. Experience in healthcare education has shown students' empathy levels decrease over time. The purpose of this quasi-experimental pretest posttest, study was to compare nursing students' empathy levels, self-confidence, and satisfaction with simulation between the use of the high-fidelity manikin simulator (HFMS) and a standardized patient (SP) used during their simulated clinical experience. Kolb's experiential learning theory was used to guide the study through the four phases specific to simulation and learning. Convenience sampling was used to recruit 135 nursing students in the pre-simulation survey; 123 participants completed the post-simulation survey with 64 in the control group (HFMS) and 59 in the experimental group (SP). Data were analyzed using an independent t-test to determine if there were any mean differences between the HFMS and SP groups in terms of empathy, satisfaction, and self-confidence. Empathy was measured using the Jefferson Scale of Empathy-Health Professions Student and the NLN's Satisfaction and Self-Confidence Scales. Results revealed there were no significant difference in students' empathy levels, self-confidence, and satisfaction. Positive social change through prioritizing nursing students' empathetic communication in patient care may be enhanced in the simulated clinical environment with various approaches. Recommendations for future research are to determine what interventions best develop nursing students' empathy, satisfaction, and self-confidence in patient care .

Abstract:

This thesis describes the evaluation of a prototype (Illustrator) for future simulator training of Within Visual Range - combat in the Swedish Air Force. The main focus was to collect and transform user acceptance data (expert opinions) to useful guidelines for continued development. Thirteen active fighter pilots participated in the study. The aim was to use expert opinion to study a) the psychological user acceptance, and b) the technical user acceptance, of the Illustrator together with c) gathering opinions for future improvement. Three psychological aspects were rated before and after the sessions to measure psychological user acceptance. For technical user acceptance, seven fidelity levels of the Illustrator were evaluated regarding realism, limitation of performance and importance of realism after the sessions. The sessions consisted of WVR-scenarios. Four different questionnaires were used for data collection. Two fidelity levels showed to diverge from the others in many ways, and were identified as major problems by the participants. No change of the psychological aspects was found between measurements. According to the results of the evaluation, suggestions and guidelines for future development are presented. Finally, issues of interest for future research are proposed.

Abstract:

The upcoming level 3 generation of self-driving vehicles will be characterized by the freedom of not having the driver’s hands on the steering wheel. This acquired freedom is posing new challenges on the traditional passenger comfort paradigm as the drivers will spend a higher amount of time doing non-driving tasks (NDRT). Certain constraints must be imposed as the level 3 generation systems will not be able to drive all the time without active feedback from the user. The driver needs to stay active enough to do takeover in a situation where it is needed to. What effect will different NDRT have on the behavior of a driver in a self-driving car? In our low fidelity driving simulator, we tested different simple actions (e.g. playing a simple 2D game). We then evaluated them based on their accident avoidance and situation awareness in the post-transition period. The results show a significant difference between the reaction speeds of the drivers before and after an active task.

Abstract:

Le raisonnement clinique est la base des professionnels de santé qui leur permet de déterminer les besoins et problèmes de santé des patients afin de les prendre en soins. Cependant, ce raisonnement clinique est source d’erreurs et son apprentissage reste problématique, preuve en ai par la littérature abondante sur le sujet.Depuis 2009, la refonte du référentiel de formation des études en soins infirmiers permet une approche de l’enseignement par compétence. Le raisonnement clinique et la prise en soins qui en découle sont intégrés aux deux premières compétences sur les dix à acquérir pour obtenir le diplôme d’infirmier.L’essor de la simulation en apprentissage ces dernières années ainsi que les recommandations de l’utilisation de cette méthode pédagogique dans la formation a permis l’émergence de nombreux outils, tels que les jeux sérieux, la réalité virtuelle et les mannequins haute-fidélité.La question principale de cette recherche est de savoir si l’utilisation d’un de ces outils, le mannequin haute-fidélité, pouvait avoir une influence sur l’acquisition des deux compétences en lien avec le raisonnement clinique.Pour cela, des indicateurs sur les trois dimensions de la compétence, les savoirs, le savoir-faire et le savoir-être ont été analysés en comparant une promotion d’étudiants infirmiers de semestre trois n’ayant pas bénéficié de cet outil technologique dans leur enseignement et des étudiants infirmier en ayant bénéficié.Ce qui ressort de cette étude expérimentale, cet outil technologique aurait une légère influence sur la qualité du raisonnement clinique des étudiants au niveau des savoirs, une amélioration de la pertinence dans les réactions d’urgence au niveau du savoir-faire. Et enfin au niveau du savoir-être, une satisfaction des étudiants quant à la posture du formateur au cours du débriefing ainsi qu’au niveau de cette méthode pédagogique, levier pouvant être une source dans la motivation des étudiants
Clinical reasoning is the basis for health professionals to determine the health needs and problems of patients for care. However, this clinical reasoning is a source of errors and its learning remains problematic, as evidenced by the abundant literature on the subject.Since 2009, the redesign of the nursing education training framework has enabled a competency-based approach to teaching. Clinical reasoning and caregiving are integrated into the first two of the ten competencies required to graduate as a nurse.The development of learning simulation in recent years, as well as the recommendations of using this teaching method in training, has led to the emergence of many tools, such as serious games, virtual reality and high fidelity models.The main question of this research is whether the use of one of these tools, the high fidelity dummy, could influence the acquisition of both clinical reasoning skills.To this end, indicators on the three dimensions of competence, knowledge, know-how and know-how were analysed by comparing a promotion of the semester three nursing students who had not benefited from this technological tool in their teaching and nursing students who had benefited from it.As this experimental study shows, this technological tool would have a slight influence on the quality of clinical reasoning of students at the level of knowledge, an improvement in relevance in emergency responses at the level of know-how. Finally, in terms of knowledge, students are satisfied with the trainer’s posture during the debriefing and with this teaching method, a lever which can be a source of students’ motivation

Abstract:

Tsunamis impose significant threat to human life and coastal infrastructure. The goal of my dissertation is to develop a robust, accurate, and computationally efficient numerical model for quantitative hazard assessment of tsunamis. The length scale of the physical domain of interest ranges from hundreds of kilometers, in the case of landslide-generated tsunamis, to thousands of kilometers, in the case of far-field tsunamis, while the water depth varies from couple of kilometers, in deep ocean, to few centimeters, in the vicinity of shoreline. The large multi-scale computational domain leads to challenging and expensive numerical simulations. I present and compare the numerical results for different important problems --- such as tsunami hazard mitigation due to presence of coastal vegetation, boulder dislodgement and displacement by long waves, and tsunamis generated by an asteroid impact --- in risk assessment of tsunamis. I employ depth-integrated shallow water equations and Serre-Green-Naghdi equations for solving the problems and compare them to available three-dimensional results obtained by mesh-free smoothed particle hydrodynamics and volume of fluid methods. My results suggest that depth-integrated equations, given the current hardware computational capacities and the large scales of the problems in hand, can produce results as accurate as three-dimensional schemes while being computationally more efficient by at least an order of a magnitude.

Abstract:

Purpose: Does manikin fidelity affect learning outcomes in neonatal resuscitation simulation? Description: This experimental design accessed and randomly assigned health care professionals (HCP) (N=60), who completed Neonatal Resuscitation Program (NRP) recertification in a simulation lab. The experimental group used a high-fidelity manikin. The control group recertified using a low-fidelity manikin. Dependant variables included learning outcomes of confidence, skill performance, and knowledge. These were measured using the newly developed Neonatal Resuscitation Confidence Tool (NRCT), Megacode Assessment, and NRP written exam. Both groups underwent the same simulated resuscitation scenario. Outcome: A significant increase in confidence with simulation was found (p<.001). HCPs using the high-fidelity simulator did not have a significant increased level of confidence, knowledge or skill performance compared to using the low-fidelity simulator. However, there was a significant increase in confidence with repeated NRP courses (p=.003). Implications: The use of simulation for NRP is important to increase capability with increased practice intervals.

Abstract:

La réforme des études médicales en France réserve une place importante à la simulation dans la formation des professionnels de santé. Dans ce contexte, les simulateurs en réalité virtuelle peuvent jouer un rôle important. Cependant, la fidélité de ces systèmes reste une question ouverte avec un manque de lignes directrices pour déterminer les niveaux appropriés de leur fidélité pour une formation efficace. Dans cette thèse, nous nous intéressons à la fidélité des simulateurs immersifs pour l'apprentissage des compétences techniques en chirurgie. Plus particulièrement, nous cherchons à comprendre comment la fidélité des interactions et artefacts pourrait affecter l'efficacité de certaines tâches effectuées dans le simulateur. Sur le plan théorique, nous proposons une articulation des notions de fidélité des simulateurs à travers un modèle basé sur les différents composants de la fidélité identifiés dans notre revue de littérature, et des différentes interfaces et interactions utilisées dans les simulateurs virtuels pour la formation des compétences techniques. Deux études expérimentales ont été réalisées pour explorer les facteurs de la fidélité du simulateur associés à une tâche de navigation et à une tâche de manipulation d'un outil et leurs impacts sur l'apprentissage de deux gestes techniques en réalité virtuelle. Les résultats montrent que des techniques d'interaction et artefacts du simulateur avec une fidélité modérée peuvent supporter la réalisation de tâches secondaires pour une formation efficace. Les concepteurs des simulateurs virtuels peuvent s'appuyer sur les recommandations issues de nos travaux afin d'éviter d'inclure certains dispositifs et composants de la fidélité qui peuvent être encombrants et coûteux sans avoir un réel impact sur l'efficacité de ces simulateurs
The reform of medical studies in France attributes an important role to simulation in healthcare professionals' training. In this context, virtual reality simulators can be very useful. However, the fidelity of these systems remains an open question with a lack of guidelines for determining their appropriate levels of fidelity to support effective training. In this thesis, we are interested in the fidelity of immersive simulators for the training of technical skills in surgery. More particularly, we investigate how the fidelity of interactions and artifacts to perform certain tasks in the simulator could affect the efficiency of these systems. From a theoretical perspective, we propose an articulation of the concepts of simulator fidelity through a model based on the various fidelity components identified in our literature review, and the various interfaces and interactions used in virtual simulators for the training of technical skills. Two experimental studies were conducted to explore the factors of simulator fidelity associated with a navigation task and a tool handling task and their impacts on the learning of two technical skills in virtual reality. The results show that the simulator's interaction techniques and artifacts with a moderate fidelity can support the completion of secondary tasks for effective training. The designers of virtual simulators can rely on the recommendations resulting from our work in order to avoid including certain devices and fidelity components, which can be cumbersome and expensive without a real impact on the efficiency of these simulators

Abstract:

Cardiovascular disease remains the leading cause of mortality in the United States, and a primary educational objective is to develop professional competency among nurses to ensure the provision of safe and effective care to the cardiac patient. Benner's theory of novice-to-expert led to the development of an evidence-based scenario for the care of the patient with chest pain using risk-free high-fidelity simulation environments that focused on assessment, history taking, and communication, while evaluating improvements in the competency of nurses providing care to chest pain patients. Thirty-six nurses volunteered in the study. Feedback from nurse educators, which led to modifications to the scenario, preceptor evaluation of participants during simulation, and post simulation feedback of participants, were analyzed using an inductive and exploratory theme analysis. Participants reported they learned meaningful information but felt somewhat confused regarding the correct course of action when multiple events occurred simultaneously. Preceptors' feedback identified participant failure to meet stated scenario expectations. Quantitative analysis of data, using one sample t test, compared the pre- and post-test scores measuring participant knowledge on assessment, history taking, and communication. Although knowledge scores increased, the difference was not clinically significant based on the negative feedback from both preceptor and participants. Accurate appraisal of nurses' competency in assessment, history-taking, and communication skills is needed prior to exposure to simulation. Simulation scenarios may be more clinically significant when tailored to an individual participant's competency levels.

Abstract:

Although Nurse Educators are aware of the advantages of simulation-based training, some still feel uncomfortable to use technology or lack the motivation to learn how to use the technology. The aging population of nurse educators cause frustration and anxiety. They struggle with how to include these tools, particularly in the light of faculty shortages. Nursing education programmes are increasingly adopting simulation in both undergraduate and graduate curricula. Scoping literature reviews show that nursing practice has changed in recent years, placing demands on nurse educators to utilise different approaches in education. The fact that nurse educators are an aging population needs to be taken into consideration and acknowledge that many of them did not grow up with computers and lag behind in technological skills. The aim of this study was to investigate the perceptions of nurse educators regarding the use of high-fidelity simulation in nursing education at a South African Private Nursing College in order to be able to determine why High-fidelity Simulators (HFS) have not yet been embraced by nurse educators and students. A national survey of nurse educators and clinical training specialists was completed with 128 participants; but only 79 completed the survey. In addition to background information, participants were questioned about their use of simulators. They were asked to complete the Technology Readiness Index. Information was also obtained regarding their perceptions of the use of HFS. Findings included indications that everyone is at the same level as far as technology readiness is concerned; this, however, does not play a large role in the use of HFS. This finding supports the educators’ need for training to adequately prepare them to use simulation equipment. Recommendations for further study include research to determine what other factors play a role in the use of HFS, studies to determine whether the benefits of HFS are superior to other teaching strategies warranting the time and financial commitment. The results of this study can be used as guidelines for other institutions to prepare their teaching staff for the use of HFS.

Abstract:

In recent years, consumers have witnessed a technological revolution that has delivered more-realistic experiences in their own homes. Expanding technologies have provided larger displays with higher resolutions, faster refresh rates, and stereoscopic capabilities. These advances have increased the level of display fidelityâ the objective degree of exactness with which real-world sensory stimuli are reproduced by a display system. Similarly, the latest generation of video game systems (e.g., Nintendo Wii and Xbox Kinect) with their natural, gesture-based interactions have delivered increased levels of interaction fidelityâ the objective degree of exactness with which real-world interactions can be reproduced in an interactive system. Though this technological revolution has provided more realistic experiences, it is not completely clear how increased display fidelity and interaction fidelity impact the user experience because the effects of increasing fidelity to the real world have not been empirically established. The goal of this dissertation is to provide a better understanding of the effects of both display fidelity and interaction fidelity on the user experience. For the context of our research, we chose virtual reality (VR) games because immersive VR allows for high levels of fidelity to be achieved while games usually involve complex, performance-intensive tasks. In regard to the user experience, we were concerned with objective performance metrics and subjective responses such as presence, engagement, perceived usability, and overall preferences. We conducted five systematically controlled studies that evaluated display and interaction fidelity at contrasting levels in order to gain a better understanding of their effects. In our first study, which involved a 3D object manipulation game within a three-sided CAVE, we found that stereoscopy and the total size of the visual field surrounding the user (i.e., field of regard or FOR) did not have a significant effect on manipulation times but two high-fidelity interaction techniques based on six degrees-of-freedom (DOF) input outperformed a low-fidelity technique based on keyboard and mouse input. In our second study, which involved a racing game on a commercial game console, we solely investigated interaction fidelity and found that two low-fidelity steering techniques based on 2D joystick input outperformed two high-fidelity steering techniques based on 3D accelerometer data in terms of lap times and driving errors. Our final three studies involved a first-person shooter (FPS) game implemented within a six-sided CAVE. In the first of these FPS studies, we evaluated display fidelity and interaction fidelity independently, at extremely high and low levels, and found that both significantly affected strategy, performance, presence, engagement, and perceived usability. In particular, performance results were strongly in favor of two conditions: low-display, low-interaction fidelity (representative of desktop FPS games) and high-display, high-interaction fidelity (similar to the real world). In the second FPS study, we investigated the effects of FOR and pointing fidelity on the subtasks of searching, aiming, and firing. We found that increased FOR affords faster searching and that high-fidelity pointing based on 6-DOF input provided faster aiming than low-fidelity mouse pointing and a mid-fidelity mouse technique based on the heading of the user. In the third FPS study, we investigated the effects of FOR and locomotion fidelity on the subtasks of long-distance navigation and maneuvering. Our results indicated that increased FOR increased perceived usability but had no significant effect on actual performance while low-fidelity keyboard-based locomotion outperformed our high-fidelity locomotion technique developed for our original FPS study. The results of our five studies show that increasing display fidelity tends to have a positive correlation to user performance, especially for some components such as FOR. Contrastingly, our results have indicated that interaction fidelity has a non-linear correlation to user performance with users performing better with â traditionalâ , extremely low-fidelity techniques and â naturalâ , extremely high-fidelity techniques while performing worse with mid-fidelity interaction techniques. These correlations demonstrate that the display fidelity and interaction fidelity continua appear to have differing effects on the user experience for VR games. In addition to learning more about the effects of display fidelity and interaction fidelity, we have also developed the Framework for Interaction Fidelity Analysis (FIFA) for comparing interaction techniques to their real-world counterparts. There are three primary factors of concern within FIFA: biomechanical symmetry, control symmetry, and system appropriateness. Biomechanical symmetry involves the comparison of the kinematic, kinetic, and anthropometric aspects of two interactions. Control symmetry compares the dimensional, transfer function, and termination characteristics of two interactions. System appropriateness is concerned with how well a VR system matches the interaction space and objects of the real-world task (e.g., a driving simulator is more appropriate than a 2D joystick for a steering task). Although consumers have witnessed a technological revolution geared towards more realistic experiences in recent years, we have demonstrated with this research that there is still much to be learned about the effects of increasing a systemâ s fidelity to the real world. The results of our studies show that the levels of display and interaction fidelity are significant factors in determining performance, presence, engagement, and usability.

Abstract:

Today, discrete event simulation is the only reliable tool for detailed analysis of complex behaviors of modern manufacturing systems. However, building high fidelity simulation models is expensive. Hence, it is important to improve the simulation modeling productivity. In this research, we explore two approaches for the improvement of simulation modeling productivity. One approach is the Virtual Factory Approach, using a general-purpose model for a system to achieve various simulation objectives with a single high fidelity model through abstraction. The other approach is the Reference Model Approach, which is to build fundamental building blocks for simulation models of any system in a domain with formal descriptions and domain knowledge. In the Virtual Factory Approach, the challenge is to show the validity of the methodology. We develop a formal framework for the relationships between higher fidelity and lower fidelity models, and provide justification that the models abstracted from a higher fidelity model are interchangeable with various abstract simulation models for a target system. For the Reference Model Approach, we attempt to overcome the weak points inherited from ad-hoc modeling and develop a formal reference model and a model generation procedure for discrete part manufacturing systems, which covers most modern manufacturing systems.

Includes bibliographical references (leaves [56]-[59]).
Minimally invasive surgery (MIS), with its aptitude for quick recovery and minimal scarring, has revolutionized surgery over the past few years. As a result, the development of a VR-based surgical trainer for MIS has been a popular area of research. However, there still remains a fundamental question of how realistic the simulation has to be for effective training. On the one hand, learning surgical practices with an unrealistic model may lead to negative training transfer. However, because of the learning abilities and perceptual limitations of the sensory, motor, and cognitive system of the human user, perfect simulation is unnecessary. Furthermore, given the large variations in human anatomy and physiology, there is no single perfect model. The question is how simple a simulation can we get away with, while at the same time preserving a level of fidelity between the virtual and real organ behavior that leads to positive training transfer. A dual station experimental platform was set up for this study. The two stations consisted of a real environment testing station and a virtual environment training station. The fidelity of the simulation could easily be adjusted in the virtual training station so that subjects could be treated with different modes of training. With the dual station setup the real environment performance of a subject before and after VE training could be measured.
(cont.) First round of experiments on the setup were conducted to investigate the effect of haptic fidelity and the effect of part task training on surgical training. Haptic fidelity was adjusted by modeling a material of non-linear stiffness to different degrees of accuracy. Subjects were initially tested on the real station performing a bimanual pushing and cutting task. They were then trained on the virtual station, with one of the three different levels of haptic fidelity or the part task trainer. Once the training was complete, the subjects were again evaluated on the real environment station to gauge their improvement in skill level. Initial results showed a marked difference in level of skill improvement between training with haptics and without. However there was no significance difference in the training effectiveness of the higher fidelity and lower fidelity model of elasticity. Also part task training proved to be an equally effective method of training for the surgical task chosen. Experiments with modeling the non-linearity materials are one of many studies that can be done on this platform, including adjusting other modes of haptic fidelity such as visco-elasticity and experiments with graphic fidelity. Results from such experiments can serve as the basis of future surgical simulation development by providing guidelines on environment fidelity required for positive training transfer to occur.

Abstract:

Controlling a formation of unmanned autonomous vehicles is a daunting prospect even when the formation operates under ideal conditions. When communication between vehicles is limited, maintaining a formation becomes difficult. In some cases the formation may become unstable. While a control law may stabilize a formation of vehicles with good communication, it may not be able to do so with poor communication. The resulting lack of formation stability affects the level of ï¬ delity the formation has to the original control law. Formation ï¬ delity is the degree to which the vehicles in a formation follow the trajectories prescribed by a control law. Many formation control laws assume certain conditions. Perfect formation ï¬ delity is not guaranteed when the vehicles in a formation are no longer operated under those conditions. We seek to mitigate the detrimental effects of poor communication and other real-world phenomena on formation ï¬ delity. Through simulation we test the effectiveness of a new way to implement an existing formation control law. Real-world conditions such as rigid-body motion, swarm dynamics, poor communication, and other phenomena are assessed and discussed. It is concluded through testing in simulation that it is possible to control a formation of boats by directing each boat with a unique set of waypoints in simulation. While these waypoints do not lead to perfect formation behavior, testing shows that implementing this control law using these waypoints allows the formation to be more robust to reduced communication.

Timson, Emma. "Flight simulation fidelity for rotorcraft design, certification and pilot training." Thesis, University of Liverpool, 2013. http://livrepository.liverpool.ac.uk/15853/.

Abstract:

The benefits of using flight simulators for rotorcraft design, certification and pilot training include reduced costs, increased safety, and control over external parameters such as environmental conditions and operational situations. The progression of technology and computing power over recent decades has led to the ability to manufacture highly sophisticated flight simulators that can be used to train complex flight operations and accurately predict the behaviour aircraft. However, such sophistication comes at a cost and there is a need to understand the trade-offs between cost and effectiveness to allow the benefits of flight simulation to be transferred to lower cost applications such as initial skills acquisition training. Assessment of simulator capabilities has traditionally been carried out with focus on the physical similarity of individual components of the simulator systems - motion system, visual system, flight model etc. However, this work is focused on the assessment of the fitness for purpose of the integrated system as a whole. This is referred throughout the thesis as perceptual fidelity, which has been defined as 'The simulator's ability to induce the behaviours known to be essential for operation of the actual aircraft in the performance of a specific task'. The novel contribution of the work in this thesis is the development of new quantitative metrics and a subjective evaluation technique that could be utilised across the simulation industry for quantification of perceptual fidelity of the overall simulation. It is intended that the methods detailed in this work could be used to support simulator development and augment current assessment techniques where appropriate. The quantitative measures of perceptual fidelity are based on comparison of ADS-33E PRF style performance metrics and the Attack metric, a control activity measure developed by Padfield et al. In this work, the utility of these metrics was assessed through correlation analyses with pilot subjective opinion. A lack of correlation in multi-axis tasks was seen and, as a result, novel metrics of pilot control strategy and adaptation have been developed in this work that show significant improvement in correlation with pilot subjective opinion. The subjective assessment methodology developed in this work is based around a new subjective rating scale – the Simulation Fidelity Rating (SFR) scale. The author contributed to the development of the SFR scale along with others at the University of Liverpool and the National Research Council (NRC) of Canada. This scale has been designed specifically to be industry applicable a d to determine the overall perceptual fidelity of the integrated simulation in a specific role. A campaign of piloted simulation and flight test trials has been conducted as the core experimental phase of this work. All the pilots completed a series of controlled experiments where a number of flying tasks were completed with a number of varied simulation models. The pilots rated each simulation against a baseline simulation using the SFR scale and their performance and control activity were recorded. This test campaign generated the pilot feedback for the development of the SFR scale and data for development of the quantitative metrics. The tests were also utilised to demonstrate how this assessment methodology can be used in controlled simulation experiments to provide previously lacking supporting evidence to simulator qualification criteria of individual components. From the analysis of the results, it was found that a more aggressive pilot excites the dynamics of the aircraft to a greater extent, thereby exposing more fidelity issues – leading to poorer SFRs. For similar reasons, an aircraft with degraded HQs was found to cause increased pilot sensitivity to transport delay. Perceptual fidelity was also found to be task dependent, In particular, pilots were found to be more susceptible to changes in off-axis response in the Acceleration-Deceleration manoeuvre than in the Precision Hover manoeuvre. These findings prove that here is a true need for simulation qualification criteria that are based on the intended use of the equipment. Significant spread was seen in the pilot ratings of perceptual fidelity in a number of cases. This was attributed partly to differing interpretation of the terminology within the Simulation Fidelity Rating (SFR) scale and also to pilot selection of task strategy. Therefore guidance material has been developed by the author from lessons learnt throughout the test campaign. This guidance material is intended to ensure best utility of the SFR scale in the future, to mitigate against the effects of differing interpretation of SFR terminology and variation in pilot task strategy through pilot briefing and correct experimental design. The SFR scale has been developed in the context of assessing a simulator for the purpose of rotary wing skills acquisition training. However, the methodologies described throughout the thesis are intended to be transferable to more sophisticated training devices for rotary-wing and fixed-wing pilot and crew training as well as for the quantification of the fidelity of certification and design simulators.

In using Modeling and Simulation for the system Verification & Validation activities, often the difficulty is finding and implementing consistent abstractions to model the system being simulated with respect to the simulation requirements. A proposition for the unified design and implementation of modeling abstractions consistent with the simulation objectives based on the computer science, control and system engineering concepts is presented. It addresses two fundamental problems of fidelity in simulation, namely, for a given system specification and some properties of interest, how to extract modeling abstractions to define a simulation product architecture and how far does the behaviour of the simulation model represents the system specification. A general notion of this simulation fidelity, both architectural and behavioural, in system verification and validation is explained in the established notions of the experimental frame and discussed in the context of modeling abstractions and inclusion relations. A semi-formal ontology based domain model approach to build and define the simulation product architecture is proposed with a real industrial scale study. A formal approach based on game theoretic quantitative system refinement notions is proposed for different class of system and simulation models with a prototype tool development and case studies. Challenges in research and implementation of this formal and semi-formal fidelity framework especially in an industrial context are discussed

Abstract:

The purpose of this study was to examine the effects of utilizing high-fidelity simulation on the team performance, perceived level of learning, and satisfaction of resident physicians in a simulated cardiac resuscitation scenario. This study was significant because it filled a gap in the literature about how methods of education impact healthcare practitioners. While a body of research exists in education on adult learning principles, there are few studies on how applying adult learning principles to professional development is an effective method of instruction in healthcare.

A convenience sample of resident physicians from two hospitals that are part of a large health system was utilized for this study. Resident physicians participated in a simulated mock cardiac resuscitation scenario monthly. The Simulated Cardiac Resuscitation Team Performance Evaluation instrument was utilized to assess the team performance of the residents in the scenarios. A program evaluation form was administered to measure perceived level of learning and satisfaction with the simulation experience.

One-way multivariate analyses of variance were conducted to evaluate the relationships between year of residency and gender and the team performance score on the Simulated Cardiac Resuscitation Team Performance Evaluation. Significant differences were not found among the years of residency on the dependent measures. Significant differences were not found between the genders on the dependent measures. A one-way multivariate analysis of variance was conducted to evaluate the relationship between year of residency and the level of satisfaction and perceived level of learning of the resident physicians. Significant differences were not found among the three years of residency on the dependent measures. A one-way multivariate analysis of variance was conducted to evaluate the relationship between gender and the level of satisfaction and perceived level of learning of the resident physicians. Significant differences were not found between genders on the dependent measures. A one-way multivariate analysis of variance was conducted to evaluate the relationship between prior use of simulation and the level of satisfaction and perceived level of learning of the resident physicians. Significant differences were not found between prior use of simulation on the dependent measures.

Abstract:

Job or task simulations are used in training when the use of the real task is dangerous or expensive, such as flying aircraft or surgery. This study focused on comparing two types of simulations used in assessments during a Clinical Performance Examination of third-year medical students: computer enhanced mannequins and standardized patients. Each type of simulation has advantages, but little empirical work exists to guide the use of different types of simulation for training and evaluating different aspects of performance. This study analyzed performance scores for different competencies as well as the reliability and validity of the different simulation types. The results showed that though neither simulator was generally superior to the other, the mannequin performed surprisingly well on interpersonal tasks such as communication and history taking.

Abstract:

The use of simulation in healthcare education has dramatically increased in popularity over the last two decades. It is thought to provide a standardised way of exposing learners to clinical situations where they can safely learn from mistakes. However, there is a lack of evidence to suggest whether simulation-based training offers significant benefits for clinical care over more traditional educational techniques, especially when the objective is a clinical judgement or diagnosis rather than a practical skill. This thesis explores whether the use of a high-fidelity patient simulator during training has an effect on the self-efficacy beliefs and clinical practice of learners, and whether this varies according to learners’ prior experience with simulation training or the clinical topic. Data were collected through semi-structured interviews with 16 qualified nurses, all of whom had attended a simulation-based training programme designed to improve clinical judgement skills. Analysis and data collection were iterative. Using a social constructionist epistemology, a thematic analysis approach was employed. High-fidelity simulation was perceived to be valuable by participants, who reported that it helped them to contextualize their knowledge and feel more confident about relevant clinical judgements. The reported impact on self-efficacy varied according to how much personal experience learners had in either the relevant clinical domain or with simulation as a training technique. However, greater belief in personal clinical judgement skills did not necessarily change reported clinical behaviour. The need for psychological fidelity during training appeared to be inversely related to clinical experience, reflecting the importance of contextual sensitivity in the planning of simulation-assisted training. Future research should examine whether these findings are reproducible in other settings, and consider whether simulation fidelity should be tailored to specific learner profiles.

Abstract:

In the light of the increasing terrorist SAMs threat to civil and military aircraft, the need of a high-fidelity, low-cost, IR signature scene modelling and simulation capability that could be used for development, testing and evaluation of IRCM systems cannot be overlooked. The performance evaluation, training and testing of IR missiles or other IR based weapon systems, is very expensive and is also dependent upon atmospheric factors. Whereas, the computer based non-destructive simulation can provide a cost-effective alternative to field trials. An effort has been made to model the IR scene signature using virtual reality modelling tools and integrating this model into the missile-target engagement and countermeasure simulator. The developed algorithm can simulate passive IR imaging seeker engagements with aerial targets. The presented algorithm uses the developed models for IR signature of the target, the background, the flare spectral and temporal responses and the flare ballistic trajectory. The missile guidance, auto-pilot and tracker algorithms have also been developed. The atmospheric conditions have been modelled, using LOWTRAN, as “good”, “typical” or “bad” to account for atmospheric transmittance and the sky-radiance. The results were analysed and validated through four test scenarios. The code is written in MATLAB which gives it openness for user verification/validation and also flexibility for any future modifications. The work presented may help the IRCM designer and pilots to evaluate potential strategies to defeat the imaging seeker threat.

Abstract:

Due to the shortage of clinical sites, nursing educators, deans, and directors are compelled to implement alternative clinical solutions such as high-fidelity simulation (HFS). The problem is that nursing educators are often not prepared to implement HFS as a teaching strategy. Faculty readiness is imperative for a successful simulation program and student outcomes. Therefore, the purpose of this study was to investigate the perceptions and practices of faculty, deans, and directors on the implementation of HFS across the nursing curriculum. Kolb's experiential learning theory provided the theoretical support for both the teaching and learning required by faculty for a successful simulation program. The key research question was to investigate how nursing educators perceived the implementation of HFS across the curriculum and how nursing deans and directors provided support for integrating HFS throughout the curriculum. The study population included 13 nursing faculty and 7 deans using simulation at prelicensure programs. Data collection included interviews, observations of simulation labs, and document analysis. Data were analyzed using open and priori coding. Five themes emerged relating to need for faculty development, need for time, need for resources, need for space, and need for support. These findings were consistent with the literature. Based on the findings, a professional development program in simulation pedagogy was developed. The faculty development program could lead to a positive social change by reducing barriers and increasing the use of simulation. Increasing the use of simulation allows nursing students to practice clinical reasoning skills and gain confidence and competence with the goal of improving patient outcomes.

This thesis concerns the design, analysis and testing of adaptive controllers for rotary wing aircraft, in particular helicopters. A non-linear helicopter model is developed and validated by trim and dynamic response analyses. A inner-outer loop cascade controller is designed with a trajectory generator in the most outer layer and an adaptive neural network controller is implemented to the inner loop. Controller is then challenged to carry out complex maneuvers autonomously under turbulence. Finally, the center of gravity location is varied to severe values to observe adaptation characteristics to investigate the requirement on the knowledge of the center of gravity location during such adaptive controller design.

Abstract:

The world's energy demand has been rapidly increasing and is projected to continue growing for at least the next two decades. With increasing global energy demand and competition from renewable energy, the oil and gas industry is striving for more efficient petroleum production. Many technical breakthroughs have enabled the drilling industry to expand the exploration to more difficult drilling such as deepwater drilling and multilateral directional drilling. For example, managed pressure drilling (MPD) offers ceaseless operation with multiple manipulated variables (MV) and wired drill pipe (WDP) provides two-way, high-speed measurements from bottom hole and along-string sensors. These technologies have maximum benefit when applied in an automation system or as a real-time advisory tool. The objective of this study is to investigate the benefit of nonlinear model-based control and estimation algorithms with various types of models. This work presents a new simplified flow model (SFM) for bottomhole pressure (BHP) regulation in MPD operations. The SFM is embedded into model-based control and estimation algorithms that use model predictive control (MPC) and moving horizon estimation (MHE), respectively. This work also presents a new Hammerstein-Wiener nonlinear model predictive controller for BHP regulation. Hammerstein-Wiener models employ input and output static nonlinear blocks before and after linear dynamics blocks to simplify the controller design. The control performance of the new Hammerstein-Wiener nonlinear controller is superior to conventional PID controllers in a variety of drilling scenarios. Conventional controllers show severe limitations in MPD because of the interconnected multivariable and nonlinear nature of drilling operations. BHP control performance is evaluated in scenarios such as drilling, pipe connection, kick attenuation, and mud density displacement and the efficacy of the SFM and Hammerstein-Wiener models is tested in various control schemes applicable to both WDP and mud pulse systems. Trusted high-fidelity drilling simulators are used to simulate well conditions and are used to evaluate the performance of the controllers using the SFM and Hammerstein-Wiener models. The comparison between non-WDP (semi-closed loop) and WDP (full-closed loop) applications validates the accuracy of the SFM under the set of conditions tested and confirms comparability with model-based control and estimation algorithms. The SFM MPC maintains the BHP within ± 1 bar of the setpoint for each investigated scenario, including for pipe connection and mud density displacement procedures that experience a wider operation range than normal drilling.
