PURPOSE To investigate the correlation in performance of cataract surgery between a virtual-reality simulator and real-life surgery using two objective assessment tools with evidence of validity. METHODS Cataract surgeons with varying levels of experience were included in the study. All participants performed and videorecorded three standard cataract surgeries before completing a proficiency-...

Virtual reality medical simulators offer the potential to provide a training environment for a novice doctor to practice skills without risk to patients. However, these simulators must be shown to provide learning before they are used in a medical training environment. This paper describes the first stage of an experiment to assess the effectiveness of the Glasgow Horse Ovary Palpation Simulato...

This research proposes the application of dynamic time warping (DTW) algorithm to analyse multivariate data from virtual reality training simulators, to assess the skill level of trainees. We present results of DTW algorithm applied to trajectory data from a virtual reality haptic training simulator for epidural needle insertion. The proposed application of DTW algorithm serves two purposes, to...

BACKGROUND Concern regarding the quality of surgical training in obstetrics and gynecology residency programs is focusing attention on competency based education. Because open surgical skills cannot necessarily be translated into laparoscopic skills and with minimally invasive surgery becoming standard in operative gynecology, the discrepancy in training between obstetrics and gynecology will ...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is very operator dependent and has a long learning curve. Simulation-based training might shorten the learning curve, and an assessment tool with solid validity evidence could ensure basic competency before unsupervised performance.A total of 16 respiratory physicians, without EBUS experience, were randomised to either...

abstract background: in recent studies, using virtual reality (vr) has been proposed as a nonpharmacological method for anxiety reduction, but until this time, its effects have not been assessed on anxiety during episiotomy repair. this study aimed to determine the effect of audiovisual distraction (vr) on anxiety in primiparous women during episiotomy repair. materials and methods: this clinic...

Virtual reality can be used to provide phobic clients with therapeutic exposure to phobogenic stimuli. However, purpose-built therapeutic VR hardware and software can be expensive and difficult to adapt to individual client needs. In this study, inexpensive and readily adaptable PC computer games were used to provide exposure therapy to 13 phobic participants and 13 non-phobic control participa...

A Mixed Reality (MR) simulation aims to enable robot developers to create safe and close-to-real world environments from a mixture of real and virtual components for experimenting with robot systems. However, the reliability of the simulation results and its usefulness in solving practical problems remain to be validated. This paper presents an evaluation of an MR simulator by examining its use...
