The use of simulators is widespread in driver behavioural research. The ability of driving simulators to achieve the high levels of behavioural fidelity desired by behavioural researchers is argued to be resultant of the physical fidelity of the simulator. Whilst attempts to maximise the physical fidelity of simulators have often been focused on the hardware capabilities of the simulator, the software of the simulator has been argued to be as important. This is because the software of a simulator controls the intelligence and the heterogeneity of the behaviours of the simulated vehicles, as well as the quality of the graphics of the simulation. Despite the importance of intelligent simulated agents, previous driving simulator studies have tended to simplify the behaviours of simulated vehicles and the scenarios that are presented to participants. This is particularly true of simulator studies investigating the decision-making of drivers at narrow passages, a relatively unregulated but hazardous situation in which two opposing vehicles must negotiate how to safely pass through a road narrowing, in which the interactive nature of the interaction has often been neglected. Following a review of the requirements for a representative narrow passage driving simulator, it is argued that co-simulation, an approach which combines multiple simulator types to create a global simulation, provides the best approach to creating intelligent simulated agents within an immersive environment for narrow passage behavioural research. As such, the development of a simulator for narrow passage behavioural research that combines SUMO and Unreal Engine is described. In particular, the development of a novel narrow passage behavioural model within SUMO that utilises previous behavioural findings is highlighted. To this end, it is argued that this approach facilitates higher levels of behavioural fidelity for narrow passage interaction studies and provides a framework for the investigation of other driver behaviours.

AbstractBackgroundSimulation training has become a core component in the training of ENT surgeons. It provides the opportunity for the repetitive practice of a surgical technique. Simulators are broadly categorised into low- and high-fidelity simulators. A method using a home microprocessor to enhance a low-fidelity surgical simulator is introduced.MethodThe Yorick tonsil tie trainer was enhanced using an Arduino microcontroller attached to the simulated inferior pole of the tonsil. The Arduino was coded to give a visual stimulus when linear motion exceeded parameters. The prototype simulator was tested to gain information on whether the enhancement could identify differences between novice and expert users.ConclusionAn enhanced low-fidelity tonsil trainer was produced using a low-cost, simple home microprocessing board. The enhanced simulator gives objective feedback allowing for self-directed learning. Further research is required to evaluate the benefits of these enhancements above non-enhanced simulation training.

Airborne sensors become a primary system in any combat program and the effectiveness depends on the coverage spectrum of the sensors and also the ability of flying machine. However evaluating the mission functionalities using sensors in flight involves tasks namely, Man Machine interface evaluation, Sensor function capability evaluation, System interface evaluation, Performance evaluation, pilot work load etc needs to carried out and the issues observed during the flight test needs to be cleared before accepting the system. It is one of the challenging task for any combat aircraft development program and proving require time, effort and also may lead to time and cost overrun. To minimize the effort one of the method adopted in recent flight development programs are using high fidelity sensor model to evaluate the mission function in the simulator which will reduce the actual test required in flight. Flight simulators during development of combat aircraft program have increased drastically in recent times with new technologies, possible to bring realism in a close room environment. However the success of any simulators depends on the fidelity of each subsystem integrated with in the simulator. Simulator contains simulation model which represents system in the aircraft world and the system which represents the outside world in a simulated manner. Mathematical based Avionics and weapon system Sensor simulation models is one of the major sub systems in any combat simulator and its level of usage depends on its fidelity. This paper proposes a unique and new methodology for evaluating the fidelity of simulated sensors used in the combat simulators. System identification technique allows generating mathematical model for dynamic systems having multiple input and output parameters. The developed model using System Identification Technique is a referent model through which the sensor model fidelity is evaluated.

AbstractFlight simulators are integral to the design/development, testing/qualification, training and research communities and their utilisation is ever expanding. The use of flight simulation to provide a safe environment for pilot training, and in research and development, must be underpinned by quantification of simulator fidelity. While regulatory simulator standards exist for flight training simulators and new standards are in development, previous research has shown that current standards do not provide a fully quantitative approach for assessing simulation fidelity, especially in a research environment. This paper reports on progress made in a research project at the University of Liverpool (Lifting Standards), in which new predicted and perceptual measures of simulator fidelity have been developed. The new metrics have been derived from handling qualities engineering practice. Results from flight tests on the National Research Council (Canada) Bell 412 ASRA research aircraft and piloted simulation trials using the HELIFLIGHT-R simulator at Liverpool are presented to show the efficacy of adopting a handling qualities approach for fidelity assessment. Analysis of the new metrics has shown an appropriate degree of sensitivity to differences between flight and simulation.

Effectiveness of low fidelity simulation toward nursing students’ self-efficacy in doing basic life support Background: The use of simulation as learning method has proven to improved student’s self-efficacy and competency. Various simulators has been developed to achieve these objectives, ranging from low, medium, to high-fidelity simulators. Among others, low-fidelity simulator has the lowest cost with the same effectiveness as other simulators.Purpose: To examine the effectiveness of low-fidelity simulation in increasing nursing students’ self-efficacy in performing Basic Life Support (BLS) skill.Method: A quasi-experimental method with non-equivalent pretest - posttest design was used to answer research questions. One chest manikin for Cardio Pulmonary Resuscitation (CPR) was used as a low-fidelity simulator in practicing BLS skill. 47 students were recruited as respondents using a purposive sampling method with students who undergoing emergency nursing course and agreed to participate in the study as inclusions criteria. Furthermore, without randomization, 23 respondents were included in the control group and 24 respondents in the intervention group. The effect of low fidelity simulation on students' self-efficacy was measured using the Basic Resuscitation Scale Self-Efficacy Scale (BRS-SES) questionnaire consisting of 18 items with responses option ranging from 1 = not confident, 2 = somewhat confident, 3 = confident, 4 = very confident, and 5 = very very confident. Questionnaire were given to respondents before and after the intervention. The collected data were analyzed using Analysis of Covariance (ANCOVA).Results: The mean score of students’ self-efficacy before intervention was 38.89 (SD = 10.149), and after intervention was 47.17 (SD = 13.099). There was no significant difference in self-efficacy mean score between the control group and the intervention group (F = 0.625, p> 0.05). So, it can be concluded that the use of low-fidelity simulation method did not have a significant effect in increasing nursing students’ self-efficacy.Conclusions: Although the use of low-fidelity simulation method does not have a significant effect in increasing nursing students’ self-efficacy, this method can be used as an effective learning method to improve nursing students’ skills and competencies.Keywords: Low fidelity simulation; Nursing student; Self-efficacy; Simulation.Pendahuluan: Penggunaan simulasi sebagai metode pengajaran dapat meningkatkan self-efficacy dan performa kompetensi siswa perawat. Beragam simulator dikembangkan untuk mencapai tujuan tersebut, mulai dari low, medium, hingga high-fidelity simulator.Diantara ketiganya, low-fidelity simulator merupakan simulator yang paling rendah dari segi pembiayaan, namun secara efektivitas sama dengan simulator lainnya.Tujuan: Mengetahui efektivitas metode low-fidelity simulation terhadap self-efficacy mahasiswa keperawatan dalam melakukan keterampilan Bantuan Hidup Dasar (BHD).Metode: Quasi eksperimen dengan non-equivalent pretest -posttest design digunakan untuk menjawab pertanyaan penelitian. Satu manikin dada untuk Resusitasi Jantung Paru (RJP) digunakan sebagai low fidelity simulator dalam pelaksanaan simulasi BHD. 47 mahasiswa direkrut sebagai responden menggunakan metode purposive sampling dengan kriteria inklusi mahasiswa yang sedang mengikuti mata kuliah keperawatan gawat darurat dan setuju untuk berpartisipasi dalam penelitian. Selanjutnya, tanpa randomisasi, 23 responden dimasukkan dalam grup kontrol dan 24 responden dalam grup intervensi. Pengaruh low fidelity simulation terhadap self-efficacy mahasiswa diukur menggunakan kuisioner Basic Resuscitation Skills Self-Efficacy Scale (BRS-SES) yang terdiri dari 18 butir pernyataan dengan rentang jawaban 1 = tidak percaya diri, 2 = agak percaya diri, 3 = percaya diri, 4 = sangat percaya diri, dan 5 = sangat sangat percaya diri. Kuisioner diberikan kepada responden sebelum dan sesudah intervensi. Data yang terkumpul selanjutnya dianalisis menggunakan Analysis of Covariance (ANCOVA).Hasil: Mean skor self-efficacy mahasiswa keperawatan sebelum intervensi adalah 38.89 (SD=10.149), dan setelah intervensi adalah 47.17 (SD=13.099). Tidak terdapat perbedaan mean yang signifikan antara skor self-efficacy kelompok kontrol dan kelompok intervensi (F= 0.625, p>0.05). Dapat disimpulkan bahwa penggunaan metode low fidelity simulation tidak memiliki pengaruh signifikan terhadap peningkatan self-efficacy mahasiswa keperawatan.Simpulan: Meskipun penggunaan metode low fidelity simulation tidak memiliki pengaruh yang signifikan terhadap peningkatan self-efficacy mahasiswa keperawatan, namun metode ini dapat digunakan sebagai metode pembelajaran yang efektif untuk meningkatkan keterampilan dan kompetensi mahasiswa keperawatan.

Full textAbstract:
The fidelity of a maritime simulator refers to how realistic the representation of a vessel and its environment look, behave, and feel in real life. Despite the benefits of using simulators in maritime training and education, there is a lack of understanding of different debates on whether higher levels of fidelity translate into better training outcomes. Therefore, to investigate and summarise what is known about maritime simulator fidelity, we conducted a systematic literature review on the maritime simulator-based training literature from 2005 to 2021. We performed bibliometric, authorship, and content analyses of thirty-six references, including white and grey literature. The results show that simulator fidelity is divided into physical and functional fidelity. While the former includes the ergonomics layout of the bridge, visual system, vessel manoeuvrability, and hydrographic modelling, the latter involves training program design, simulator session design, and the role of the instructor. The results reveal that there is no prevalent tradition in the literature, a low number of citations, and the references are dispersed among many publications, authors, and institutions. Despite the fact that the prevalence of studies employing high-fidelity simulators can positively impact training, most of the studies are based on subjective evaluation, if any evidence is provided, and were produced by Scandinavian and European institutions and researchers. To address these limitations, we propose a research agenda containing three recommendations.

The tremendous expense and inherent dangers of training in the aircraft have led to the increased use of simulators for practicing and maintaining air combat skills; However, the advantages and disadvantages of using high or low-fidelity simulators for such training must be specified. An experiment was conducted to examine the in-simulator performance differences between pilots flying lower-fidelity simulators compared to higher-fidelity simulators. The primary difference between the two simulators is the visual scene field-of-view. Sixteen U.S. Air Force F-16 pilots flew standard training missions as an integrated team of four (a “four-ship”) with two pilots flying in the high-fidelity simulators and two pilots flying in the lower-fidelity simulators. Various subjective and objective measures were collected to assess the pilots' ability to maintain a briefed formation. Overall, the results suggest that pilots who practice four-ship employment in the lower-fidelity simulators can perform at the same level as those who practice in the high-fidelity simulators. Future analyses should be conducted to examine the impact of simulator fidelity on other air combat skills and on training effectiveness.

A limitation of the extant research on the training effectiveness of high versus low fidelity simulation is the lack of a standardized methodology to define high and low fidelity in way that is generalizable across studies. This paper presents a novel approach to standardizing the definition of fidelity using The Simulation Fidelity (SiFi) scale. The SiFi scale is a 6-point scale used to rate the fidelity of a simulation. The present study examines the inter-rater reliability of the SiFi scale to define the fidelity of simulated task elements with respect to their real-world referent. Two subject matter experts (SMEs) completed a series of aviation maneuvers in a virtual reality (VR) simulator. Following the maneuvers, each SME provided 117 ratings of simulated elements using the SiFi scale. Cohen’s k was calculated to determine interrater reliability. Results of this analysis indicate strong reliability of the SiFi scale.

BackgroundSimulation technology is widely used in medical education, providing an environment in which students can develop and practise a multitude of skills that are relevant to clinical practice, without the risk of harm to patients.MethodsWe conducted a mixed methods cross-over study with quantitative and qualitative outcomes. This analysed students’ perceptions of two simulation technologies: a high-fidelity patient simulator and virtual reality. Twenty final year medical students completed a questionnaire after having experienced both simulation modalities.ResultsStudents scored the patient simulator higher in domains such as developing team working and ‘ABCDE assessment skills’, whereas the virtual reality simulation was more immersive and fun. Participants found the patient simulator more useful in preparing them for clinical practice.ConclusionMedical students in this study expressed that a high-fidelity patient simulator, in a simulated clinical environment, was of greater value to their preparation for clinical practice than virtual reality simulation of a similar environment. However, the virtual reality simulation offered a near comparable experience, and was found to be was enjoyable, immersive and easily portable.

In some evolutionary robotics experiments, evolved robots are transferred from simulation to reality, while sensor/motor data flows back from reality to improve the next transferral. We envision a generalization of this approach: a simulation-to-reality pipeline. In this pipeline, increasingly embodied agents flow up through a sequence of increasingly physically realistic simulators, while data flows back down to improve the next transferral between neighboring simulators; physical reality is the last link in this chain. As a first proof of concept, we introduce a two-link chain: A fast yet low-fidelity ( lo-fi) simulator hosts minimally embodied agents, which gradually evolve controllers and morphologies to colonize a slow yet high-fidelity ( hi-fi) simulator. The agents are thus physically scaffolded. We show here that, given the same computational budget, these physically scaffolded robots reach higher performance in the hi-fi simulator than do robots that only evolve in the hi-fi simulator, but only for a sufficiently difficult task. These results suggest that a simulation-to-reality pipeline may strike a good balance between accelerating evolution in simulation while anchoring the results in reality, free the investigator from having to prespecify the robot's morphology, and pave the way to scalable, automated, robot-generating systems.

All-attitude flight simulators can simulate flight attitude through three rotational degrees of freedom. In this paper, the inverse kinematics and singularity of the all-attitude simulator are analyzed. Because a singularity will reduce the fidelity of the flight attitude simulation, we investigated ways to resolve this problem. An approximate method for quickly quantifying singularities is proposed. Static damping and dynamic damping are designed to optimize the singularity of the all-attitude simulator and improve the fidelity of flight attitude simulation. Attitude data of typical flight movements, whose inverse kinematics has an obvious singular position, are used to test the two methods. The results of the simulation show that the two methods are feasible and effective, and that dynamic damping has better control over singular excesses than static damping.

Background: Development of a high-fidelity cardiac surgery simulator (CSS) requires integration of a heart model with a mock cardiopulmonary bypass (CPB) circuit that can provide feedback to mimic the pathophysiology of cardiac surgery. However, the cost of commercially available simulators precludes regular use. We describe steps in the construction of a high-fidelity CSS that integrates a pulsatile paracorporeal ventricular-assist device (Pulse-VAD) and a commercially available CPB simulator. Methods/Results: Eight porcine hearts were initially prepared. The configuration consisted of cannulation of the distal descending aorta and the inferior vena cava to enable pressurization of the heart after connection to the Califia® simulator, as well as Pulse-VAD cannulation (fitted with inflatable balloons) of both ventricles. After each simulation run, the team addressed key issues to derive successive model changes through consensus. Key modifications included: a) pressure maintenance of the cardiac chambers (removal of lungs, Pulse-VAD cannulation sites at the left pulmonary artery and vein, double ligation of arch vessels); b) high-fidelity beating of both ventricles (full Pulse-VAD bladder filling and ensuring balloon neck placement at the valvular plane) and c) reproducible management of porcine anatomy (management of porcine aorta, ligation of left azygous vein and shortened ascending thoracic aortic segment). Conclusion: A CSS can be prepared at low cost, with integration into a high-fidelity CPB simulator with a novel beating heart component. This setup can be used in teaching the basics of CPB techniques and complex surgical procedures. Future work is needed to validate this model as a simulation instrument.

Abstract At the heart of a flight simulator resides the mathematical representation of aircraft behaviour in response to control inputs, atmospheric disturbances and system inputs including failures and malfunctions. While this mathematical model can never be wholly accurate, its fidelity, in comparison with real world behaviour, underpins the usefulness of the flight simulator. The present paper examines the state of the art achieved in validating mathematical models for helicopter simulators, addressing the strengths and weaknesses of the present European standard for the qualification of helicopter flight simulators, JAR FSTD-H (previously JAR-STD-1H/2H/3H). Essential questions are examined, such as: What is the required model fidelity to guarantee a simulation is sufficiently representative to be fit for purpose? Are the tolerances set in the current standards fine enough that they lead to only minor changes in handling qualities? What is an acceptable tuning process for the simulation? What is the effect of modelling fidelity on the overall pilot control strategy? What is the relationship between the settings of the simulator cueing environment and the behaviour of the pilot? What is the industrial experience on qualification of flight simulators that might usefully inform developments? Many of these questions were addressed in Europe in a previous GARTEUR Action Group (AG) HC/AG-12 the results of which are documented in this paper. Solutions are proposed for improving the current JAR-FSTD standard with respect to validation of mathematical models.

A multitude of simulator systems for endoscopic sinus surgery (ESS) are available as training tools for residents preparing to enter the operating room. These include human cadavers, virtual reality, realistic anatomic models, and low-fidelity gelatin molds. While these models have been validated and evaluated as independent tools for surgical trainees, no study has performed direct comparison of their outcomes. To address this deficiency, we aimed to evaluate the utility of high-fidelity and low-fidelity trainers as compared to a traditional control (no simulator exposure) for novice trainees acquiring basic ESS skills. Thirty-four first-year medical students were randomized to 3 groups and taught basic sinus anatomy and instrumentation. Two groups received training with either the high-fidelity or low-fidelity trainer, while 1 group served as control. These groups were then tested with cadaveric specimens. These sessions were recorded and graded by an expert. There was no statistical difference in performance between the 3 study groups with regard to identification of anatomy, endoscopic competency, or completion of basic tasks. When the high-fidelity and low-fidelity arms were grouped into a single “trained” cohort, they demonstrated significantly improved time to completion for basic anatomy ( P = .043) and total time ( P = .041). This is the first study to perform a direct comparison of performance between high-fidelity and low-fidelity ESS simulators and controls. Although we found no difference in performance of novice trainees with regard to basic anatomical identification or procedural tasks associated with ESS, the use of ESS simulators may improve time to completion.

There is interest in how pilots perceive simulator fidelity and rate self-performance in virtual reality flight training. Ten participants were trained to perform a target tracking task in a helicopter flight simulation. After training objective performance, the median tracking error, was compared to subjective self-evaluations in a number of flying conditions where the cues available to our pilots were manipulated in a factorial design: the simulator motion platform could be active or static, audio cues signalling the state of the turbine could be those used during training, non-informative, or an obviously different but informative ‘novel’ sound. We tested participants under hard and easy flying conditions. Upon completion of each test condition, participants completed a 12-statement Likert-scale with items concerning their performance and helicopter simulator fidelity. Objective performance measures show that flight performance improved during training and was affected by audio and motion cues. The subjective data shows that participants reliably self-evaluated their own performance and simulator fidelity. However, there were instances where subjective and objective measures of performance or fidelity did not correlate. For example, although participants rated the ‘novel’ turbine sound as having low fidelity, it behaviourally caused no difference with respect to the turbine sound used in training. They were also unable to self-evaluate outcome of learning. We conclude that whilst subjective measures are a good indicator of self-performance, objective data offers a valuable task-oriented perspective on simulator fidelity.

Background and Aim: Blood collection from dogs is the most commonly performed procedure in the medical clinic. However, different factors can interfere with the quality of the material collected, potentially causing complications for patients. Simulated skill training is a teaching strategy designed to provide early training to students, develop their skills and self-confidence, and increase the procedure's success while reducing complications. Therefore, the aim of this study was to evaluate skill training using a low-fidelity simulator in the peripheral venipuncture procedure and examine the training's influence on the in vivo procedure. Materials and Methods: To assess skill training, this study used a low-fidelity simulator in the peripheral venipuncture procedure and examines the training's effect on the in vivo procedure. In total, 100 dogs, 65 undergraduate students, 3 veterinarians, and 4 previously trained evaluators participated. The canine in vivo venipuncture procedure was evaluated both before and after the simulated skill training and the low-fidelity simulator training. Data were collected on participants' self-confidence levels. Results: Local complications occurred during in vivo practice; however, after training, they decreased. Gloves were more frequently used during the procedure, resulting in a reduction of both harvest attempts and complications, as well as increased levels of self-confidence in post-training participants. The simulator developed had low fidelity, low cost, and was easy to create. Conclusion: Skill training in peripheral venipuncture using a low-fidelity simulator positively influences student learning, increases their self-confidence during in vivo harvesting, and reduces the complications of the procedure, improving patient well-being.

HighlightsDescribes the creation of a new high-fidelity tractor driving simulator.Describes the perceived realism of a tractor driving simulator among 99 Midwestern farm equipment operators.Examines how farm equipment operator characteristics affect perceived realism of a tractor driving simulator.Discusses potential improvements for future generations of tractor driving simulators.Abstract. Transportation-related incidents are the leading cause of occupational fatalities for all industries in the U.S., including the agricultural industry, which suffers thousands of crashes involving farm equipment each year. Simulated driving studies offer a safe and cost-effective way to conduct driving research that would not be feasible in the real world. A tractor driving miniSim was developed and then evaluated for realism at the University of Iowa among 99 Midwestern farm equipment operators. It is important for driving simulators to have a high degree of realism for their results to be applicable to non-simulated driving operations. High-fidelity driving simulators facilitate extrapolations made by driving research but should be re-tested for realism when changes are made to the design of the simulator. The simulator used in this study emulated a tractor cab with realistic controls, three high-resolution screens, and high-fidelity sound. After completing a 10-minute drive, farm equipment operators completed a survey and scored four specific domains assessing specific characteristics (i.e., appearance, user interface, control, and sound) of the tractor simulator’s realism using a seven-point Likert scale (from 0 = not at all realistic to 6 = completely realistic). An overall realism score and domain scores were calculated. Farm equipment operators were also asked to provide recommendations for improving the tractor miniSim. Overall, farm equipment operators rated the simulator’s realism favorably (i.e., >3 on a scale from 0 to 6) for all individual items and domains. The appearance domain received the highest average realism score (mean = 4.58, SD = 1.03), and the sound domain received the lowest average realism score (mean = 3.86, SD = 1.57). We found no significant differences in realism scores across farm equipment operator characteristics. The most frequently suggested improvements were to tighten the steering wheel (27%), make the front tires visible (19%), and that no improvements were needed to improve the simulator realism (18%). This study demonstrates that the new tractor miniSim is a viable approach to studying farm equipment operations and events that can lead to tractor-related crashes. Future studies should incorporate the suggested improvements and seek to validate the simulator as a research and outreach instrument. Keywords: Driving simulator, Farm equipment operators, Realism, Tractors.

A medium-fidelity virtual reality (VR) flight simulator was developed to evaluate how aircraft pilots perceived simulated flights in the VR environment compared with conventional mockup-based simulators. In Experiment 1, student and instructor pilots conducted ten repeating flights in the simulator. Three extreme flight conditions were created, and participants rated perceptions of the extreme flights using multiple criteria. In Experiment 2, pilots manipulated G1000 electronic cockpit systems in the simulator during three repeating simulated flights and were asked to rate their perceptions of the manual controls. Participants perceived that the VR simulator was similar to or better than conventional simulators for all given Experiment 1 criteria and found that repetition made the operations easier. However, manipulating electronic cockpit systems was still not considered better than using conventional simulators, even though it became easier by repetition. Participants liked the 360-degree angle of visibility in the VR environment.

Fidelity of vehicle dynamics is directly affected by virtual terrain data in driving simulator, in order to satisfy both high fidelity and simulation frame rate, management of high resolution terrain data is necessary. Vehicle dynamics process and terrain data triangle grid structure are introduced firstly, then a data management algorithm is described, whole terrain data is divided into small terrain blocks identified by their row and column, according to driver’s view range, blocks around vehicle position are loaded rather than all terrain data, therefore dynamics calculation efficiency and simulation frame rate are improved. Finally, a simple driving simulator is created to test effect of this algorithm, the results show it is feasible and valid for driving simulator.

Medical simulation provides a realistic environment for practitioners to experience a planned clinical event in a controlled educational setting. We established a simulation model composed of synthetic ballistic gelatin that provided an inexpensive high-fidelity model for our extracorporeal membrane oxygenation (ECMO) team members to develop, master, and maintain clinical skills necessary for percutaneous cervical or femoral cannulation. The simulation component includes a cervical torso or femoral percutaneous synthetic gelatin model that is attached to either a static fluid model or to the high-fidelity perfusion simulator. Either model can be accessed with ultrasound guidance, cannulated with appropriately sized cannula, and connected to an in situ ECMO circuit. This article explains how the model is made and connected to the simulator with the purpose of re-creating this high-fidelity experience at any institution.

Full textAbstract:
Perceptions of one's ability to perform a task, or self-efficacy, is one aspect of the multifaceted nature of an individual's identity. It is generally accepted that having a high perceived self-efficacy about a certain task can lead to positive performance outcomes. Bandura (1977) has suggested that efficacy influences and expectations can come from four sources: personal performance accomplishments; vicarious experiences; verbal persuasion; and emotional arousal. Trainers and training agencies use a variety of simulations and simulators to provide learners with valuable and necessary training experiences. This mixed methods study explored the influence of one high-fidelity virtual training simulator on the learners' self-efficacy. Participants in this study were recruits enrolled in a law enforcement academy. Data were collected through 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), observations of participants using the simulator, and post simulator interviews. The most prominent theme that emerged from the data was emotional arousal due to the realism of the virtual environment. Emotional arousal seemed to impact both their perceived self-efficacy and task performance; yet, despite the variety of emotional arousal they experienced, the participants perceived their training in the high-fidelity virtual training simulator as valuable.

AbstractBackground: High fidelity medical simulators (HFMS) are accepted tools for health care instruction. The use of HFMS was incorporated into an International Trauma Life Support course, and course participants were surveyed regarding attitudes toward HFMS.Methods: Course participants, including physicians, nurses, and prehospital personnel, were given pre- and post-course questionnaires measuring their confidence in knowledge and treatment of trauma resuscitation, as well as their attitudes towards the utility and realism of immersive simulation. The participants were randomly assigned to take a course examination either before or after their simulator session.Results: Thirteen course participants of varying backgrounds and degrees of clinical experience were surveyed and tested. All surveyed areas improved following simulator training, including comfort level with simulation as a training method (17%), perception of the realism of HFMS (15%), and reported self-confidence in knowledge, experience and training in trauma care (27%). Test scores were improved in the post-simulation group as opposed to the pre-simulation group (86% pass rate in the post-simulation test group versus 50% pass rate in the pre-simulation test group).Conclusions: High fidelity medical simulation was accepted by medical professionals of different backgrounds and experience. Attitudes towards simulation and self-confidence improved after simulator sessions, as did test scores, suggesting improved comprehension and retention of course materials. Further testing is required to validate the findings of this small, observational study.

Full textAbstract:
Radiofrequency ablation (RFA) is a treatment used in the management of various arrhythmias including atrial fibrillation. Enhanced training for electrophysiologists through the use of physical simulators has a significant role in improving patient outcomes. The requirements for a high-fidelity simulator for cardiac RFA are challenging and not fully met by any research or commercial simulator at present. In this study, we have produced and evaluated a 3D-printed, bi-atrial model contained in a custom-made enclosure for RFA simulation using a new soft tissue-mimicking polymer, Layfomm-40, combined with thermochromic pigment and barium sulphate in an acrylic paint carrier. We evaluated the conductive properties of Layfomm-40, its sensitivity to RFA, and its visibility in X-ray imaging, and carried a full simulation of RFA in the cardiac catheterization laboratory by an electrophysiologist. We demonstrated that a patient-specific 3D-printed Layfomm-40 bi-atrial model coated with a custom thermochromic/barium sulphate paint was compatible with the CARTO3 electroanatomic mapping system and could be effectively imaged using X-ray fluoroscopy. We demonstrated the effective delivery and visualization of radiofrequency ablation lesions in this model. The simulator meets nearly all the requirements for high-fidelity physical simulation of RFA. The use of such simulators is likely to have impact on the training of electrophysiologists and the evaluation of novel RFA devices.

INTRODUCTION The Chief Medical Officer's 2008 annual report highlighted the importance of simulation in medical training. 1 Simulator development has focused on increasing authenticity and fidelity. Development has not necessarily been guided by evidence for educational improvement. On reviewing 34 years of literature, Issenberg et al identified ten features of high-fidelity medical simulators that facilitate learning. 2 This study compares cadaveric temporal bone (CTB) simulation with the Voxel-Man TempoSurg (VT) virtual reality simulator in addressing these features. SUBJECTS AND METHODS A questionnaire was designed comparing the VT with CTB. Fourteen trainees and six consultants completed the questionnaire after using the simulator. RESULTS The VT is better at allowing repetitive practice, ease of control of difficulty, and capturing clinical and pathological variation. The VT is as good as CTB in curriculum integration, allowing multiple learning strategies, providing a controlled environment, individualising learning and defining benchmarks. It appears worse with regards to face validity and feedback. CONCLUSIONS Virtual reality simulation and CTB have features that allow effective learning. Some of these are common to both, in some CTB is better and in others virtual reality is better. Virtual reality could be a significant mode of learning supplementary to CTB and experience in the operating theatre.

Background Critical incident reporting and observational studies have identified nontechnical skills that are vital to successful anesthesia crisis management. Examples of such skills include task management, team working, situation awareness, and decision making. These skills are not necessarily acquired through clinical experience and may need to be specifically taught. This study uses a high-fidelity patient simulator to assess the effect of repeated exposure to simulated anesthesia crises on the nontechnical skills of anesthesia residents. Methods After institutional research board approval and informed consent, 20 anesthesia residents were recruited. Each resident was randomized to participate as the primary anesthesiologist in the management of three different simulated anesthesia crises using a high-fidelity patient simulator. After each session, videotaped footage was used to facilitate debriefing of their nontechnical skills. The videotapes were later reviewed by two expert blinded independent assessors who rated each resident's nontechnical skills by using a previously validated and reliable marking system. Results : A significant improvement in the nontechnical skills of residents was demonstrated from their first to second session and from their first to third session (both P < 0.005). However from their second to third session, no significant improvement was observed. Interrater reliability between assessors was modest (single rater intraclass correlation = 0.53). Conclusion A single exposure to anesthesia crises using a high-fidelity patient simulator can improve the nontechnical skills of anesthesia residents. However, an additional simulation session may confer little or no additional benefit.

Full textAbstract:
The use of virtual reality simulators for perceptual-motor training has increased in recent years. However, few virtual sport environments have been shown to be effective in transferring learning to the real world. From this perspective, concepts of validity and fidelity are known to be good predictors, highlighting the need to establish a method of testing them. This study measures the validity and fidelity of a relay simulator in the most comprehensive way by testing elements of physical, biomechanical, and psychological fidelity and construct validity. Twelve national-level athletes performed race initiation tasks during a baton handover in both virtual and real environment conditions. The athletes’ perceptual-motor behavior was compared on both group and individual scales (construct validity and biomechanical and psychological fidelity). These measures were complemented by measures of workload (psychological fidelity) and presence (physical fidelity). A group-scale analysis showed no significant difference in the initiation behavior of the athletes, and all of them reported high levels of presence. Moreover, individual-scale measures showed a clear maintenance of perceptual-motor behavior for most athletes. Despite few differences being found in workload, these results largely support the simulator’s validity and fidelity, which is an important step towards integrating the simulator into the training protocols of elite athletes.

Background Human patient simulators and airway training manikins are widely used to train airway management skills to medical professionals. Furthermore, these patient simulators are employed as standardized "patients" to evaluate airway devices. However, little is known about how realistic these patient simulators and airway-training manikins really are. This trial aimed to evaluate the upper airway anatomy of four high-fidelity patient simulators and two airway trainers in comparison with actual patients by means of radiographic measurements. The volume of the pharyngeal airspace was the primary outcome parameter. Methods Computed tomography scans of 20 adult trauma patients without head or neck injuries were compared with computed tomography scans of four high-fidelity patient simulators and two airway trainers. By using 14 predefined distances, two cross-sectional areas and three volume parameters of the upper airway, the manikins' similarity to a human patient was assessed. Results The pharyngeal airspace of all manikins differed significantly from the patients' pharyngeal airspace. The HPS Human Patient Simulator (METI®, Sarasota, FL) was the most realistic high-fidelity patient simulator (6/19 [32%] of all parameters were within the 95% CI of human airway measurements). Conclusion The airway anatomy of four high-fidelity patient simulators and two airway trainers does not reflect the upper airway anatomy of actual patients. This finding may impact airway training and confound comparative airway device studies.

User simulators can rapidly generate a large volume of timely user behavior data, providing a testing platform for reinforcement learning-based recommender systems, thus accelerating their iteration and optimization. However, prevalent user simulators generally suffer from significant limitations, including the opacity of user preference modeling and the incapability of evaluating simulation accuracy. In this paper, we introduce an LLM-powered user simulator to simulate user engagement with items in an explicit manner, thereby enhancing the efficiency and effectiveness of reinforcement learning-based recommender systems training. Specifically, we identify the explicit logic of user preferences, leverage LLMs to analyze item characteristics and distill user sentiments, and design a logical model to imitate real human engagement. By integrating a statistical model, we further enhance the reliability of the simulation, proposing an ensemble model that synergizes logical and statistical insights for user interaction simulations. Capitalizing on the extensive knowledge and semantic generation capabilities of LLMs, our user simulator faithfully emulates user behaviors and preferences, yielding high-fidelity training data that enrich the training of recommendation algorithms. We establish quantifying and qualifying experiments on five datasets to validate the simulator's effectiveness and stability across various recommendation scenarios.

ABSTRACTThis paper adds data to help establish fidelity criteria to accompany the simulator motion system diagnostic test specified by the International Civil Aviation Organisation. Twelve airline transport pilots flew three tasks in the NASA Vertical Motion Simulator under four different motion conditions. The experiment used three different hexapod motion configurations, each with a different trade-off between motion filter gain and break frequency, and one large motion configuration that utilised as much of the simulator's motion space as possible. The motion condition significantly affected (1) pilot motion fidelity ratings, and sink rate and lateral deviation at touchdown for the approach and landing task, (2) pilot motion fidelity ratings, roll deviations, maximum pitch rate, and number of stick shaker activations in the stall task, and (3) heading deviation after an engine failure in the take-off task. Significant differences in pilot-vehicle performance were used to define initial objective motion cueing criteria boundaries. These initial fidelity boundaries show promise but need refinement.

Full textAbstract:
Highly autonomous vehicles (HAV) have the potential of improving road safety and providing alternative transportation options. Given the novelty of HAVs, high-fidelity driving simulators operating in an autonomous mode are a great way to expose transportation users to HAV prior to HAV adoption. In order to avoid the undesirable effects of simulator sickness, it is important to examine whether factors such as age, sex, visual processing speed, and exposure to acclimation scenario predict simulator sickness in driving simulator experiments designed to replicate the HAV experience. This study identified predictors of simulator sickness provocation across the lifespan (N = 210). Multiple stepwise backward regressions identified that slower visual processing speed predicts the Nausea and Dizziness domain with age not predicting any domains. Neither sex, nor exposure to an acclimation scenario predicted any of the four domains of simulator sickness provocation, namely Queasiness, Nausea, Dizziness, and Sweatiness. No attrition occurred in the study due to simulator sickness and thus the study suggests that high-fidelity driving simulator may be a viable way to introduce drivers across the lifespan to HAV, a strategy that may enhance future HAV acceptance and adoption.

Purpose: This study evaluated the acquisition and retention effects on diabetes knowledge and academic self-efficacy of patient simulation-based hypoglycemia scenario using a high-fidelity simulator. Methods: A nonequivalent control group pretest/posttest repeated measures quasi-experimental design determined if nursing simulation using a high-fidelity simulator helps students acquire and retain diabetes knowledge and academic self-efficacy. A total of 101 nursing students from two universities participated in this study, comprising the experimental and control groups. The experimental group (n=52) at a university in S city comprised participants in an adult nursing class, nursing practicum, and simulation education. The control group (n=49) at a university in C city participated in an adult nursing class and nursing practicum without simulation education. Results: The experimental group had statistically significant group-time interaction effects on diabetes knowledge (p=.044) and self-confidence (p<.001) of academic self-efficacy compared to the control group. Conclusion: The results indicated that the patient simulation-based hypoglycemia scenario using a high-fidelity simulator applied to nursing education is useful in encouraging nursing students to engage in strategies with acquisition and retention effects, enhancing their diabetes knowledge and self-confidence of academic self-efficacy. Therefore, educators should use simulation programs effectively with nursing classes and practicum to enhance the effects of nursing competencies.

Simulation is a synthetic representation of a real-world process with sufficient reliability to facilitate learning through contemplation and practice without the hazard, innate in a real-life experience. Nowadays, simulation is a useful accompaniment to medical education as pre-exposure to necessary clinical skills as exposure in the real clinical setting may be insufficient. Clinical skills and performance are considered core proficiency and are crucial to the professionals. This can enable the students to familiarize themselves with patient examination and hands-on- training by using models before coming across patients directly. Simulators are broadly classified into two broad categories: 1. High-fidelity Simulators and 2. Low-fidelity simulators. The fidelity of a simulator is decided by the extent to which it provides realism through characteristics. Simulation Based Medical Education (SBME) provides a safe environment for the students to acquire their psychomotor skill but is not necessarily better than other types of instruction as there is a high degree of variability between studies. SBME has been introduced in the health care field and now it is becoming one of the most popular teaching techniques for improving patient safety and care. It would be advantageous if it is included in medical curricula as it may proof boon for the young medicos. Keywords: Medical simulation; SBME; Simulators

Background Simulation in virtual environments has become a new paradigm for surgeon training in minimally invasive surgery (MIS). However, this technology is expensive and difficult to access. Objective This study aims first to describe the development of a new gesture-based simulator for learning skills in MIS and, second, to establish its fidelity to the criterion and sources of content-related validity evidence. Methods For the development of the gesture-mediated simulator for MIS using virtual reality (SIMISGEST-VR), a design-based research (DBR) paradigm was adopted. For the second objective, 30 participants completed a questionnaire, with responses scored on a 5-point Likert scale. A literature review on the validity of the MIS training-VR (MIST-VR) was conducted. The study of fidelity to the criterion was rated using a 10-item questionnaire, while the sources of content-related validity evidence were assessed using 10 questions about the simulator training capacity and 6 questions about MIS tasks, and an iterative process of instrument pilot testing was performed. Results A good enough prototype of a gesture-based simulator was developed with metrics and feedback for learning psychomotor skills in MIS. As per the survey conducted to assess the fidelity to the criterion, all 30 participants felt that most aspects of the simulator were adequately realistic and that it could be used as a tool for teaching basic psychomotor skills in laparoscopic surgery (Likert score: 4.07-4.73). The sources of content-related validity evidence showed that this study’s simulator is a reliable training tool and that the exercises enable learning of the basic psychomotor skills required in MIS (Likert score: 4.28-4.67). Conclusions The development of gesture-based 3D virtual environments for training and learning basic psychomotor skills in MIS opens up a new approach to low-cost, portable simulation that allows ubiquitous learning and preoperative warm-up. Fidelity to the criterion was duly evaluated, which allowed a good enough prototype to be achieved. Content-related validity evidence for SIMISGEST-VR was also obtained.

AbstractA new rating scale for capturing pilot subjective assessment of simulation fidelity is described in this paper. The scale has been developed through a series of flight and simulation trials using six test pilots from a variety of backgrounds, and is based on the methodology utilised with the Cooper-Harper Handling Qualities Rating scale and the concepts of transfer of training, comparative task performance and task strategy adaptation. The development of the new rating scale has been undertaken using simulations of rotary-wing aircraft on the University of Liverpool’s HELIFLIGHT-R research simulator, in conjunction with the Canadian Flight Research Laboratory’s Bell 412 ASRA in-flight simulator. The utility of the scale applied to locating fidelity boundaries for quantitative metrics is illustrated for an inter-axis coupling criterion. The work described in this paper is preliminary in nature, and research activities are on-going to continue the validation of the fidelity rating scale.

This study was undertaken to compare performance using a surgical robot after training with one of three simulators of varying fidelity. Methods: Eight novice operators and eight expert surgeons were randomly assigned to one of three simulators. Each participant performed two exercises using a simulator and then using a surgical robot. The primary outcome of this study is performance assessed by time and GEARS score. Results: Participants were randomly assigned to one of three simulators. Time to perform the suturing exercise (novices vs. experts) was significantly different for all 3 simulators. Using the da Vinci robot, peg transfer showed no significant difference between novices and experts and all participants combined (mean time novice 2.00, expert 2.21, p = 0.920). The suture exercise had significant differences in each group and all participants combined (novice 3.54, expert 1.90, p = 0.001). ANOVA showed p-Values for suturing (novice 0.523, expert 0.123) and peg transfer (novice 0.742, expert 0.131) are not significantly different. GEARS scores were different (p < 0.05) for novices and experts. Conclusion: Training with simulators of varying fidelity result in similar performance using the da Vinci robot. A dry box simulator may be as effective as a virtual reality simulator for training. Further studies are needed to validate these results.

Background The learning process of physiological mechanisms of childbirth and its management are important elements in the education of medical students. In this study, we verify how the use of a high-fidelity simulator of childbirth improves competence of students in this regard.Methods A total of 132 medical students were recruited for the study in order to attend a physiological childbirth in a no-hospital environment after being assigned to two groups. The control group received only a normal cycle of lectures, while the simulation (SIM) group followed a specific training session on the simulator. Subsequently, both groups were assessed for their technical and non-technical skills in a simulated childbirth. Also, a self-assessment test regarding their self-confidence was administrated before and after simulation, and repeated after 8 weeks.Results The SIM group showed better performance in all the domains with a better comprehension of the mechanisms of childbirth, managing and assistance of labour and delivery. In addition, compared to the control group, they presented a better self-related awareness and self-assurance regarding the possibility of facing a birth by themselves.Conclusion The present study demonstrated that the use of a high-fidelity simulator for medical students allows a significant improvement in the acquisition of theoretical and technical expertise to assist a physiological birth.
