{"title":"Multimodal Approach to Assess a Virtual Reality-based Surgical Training Platform.","authors":"Doga Demirel, Hasan Onur Keles, Chinmoy Modak, Kubranur Kara Basturk, Jacob R Barker, Tansel Halic","doi":"10.1007/978-3-031-35634-6_30","DOIUrl":"10.1007/978-3-031-35634-6_30","url":null,"abstract":"<p><p>Virtual reality (VR) can bring numerous benefits to the learning process. Combining a VR environment with physiological sensors can be beneficial in skill assessment. We aim to investigate trainees' physiological (ECG) and behavioral differences during the virtual reality-based surgical training environment. Our finding showed a significant association between the VR-Score and all participants' total NASA-TLX workload score. The extent of the NASA-TLX workload score was negatively correlated with VR-Score (R<sup>2</sup> =0.15, P < 0.03). In time-domain ECG analysis, we found that RMSSD (R<sup>2</sup> =0.16, P < 0.05) and pNN50 (R<sup>2</sup> =0.15, P < 0.05) scores correlated with significantly higher VR-score of all participants. In this study, we used SVM (linear kernel) and Logistic Regression classification techniques to classify the participants as gamers and non-gamers using data from VR headsets. Both SVM and Logistic Regression accurately classified the participants as gamers and non-gamers with 83% accuracy. For both SVM and Linear Regression, precision was noted as 88%, recall as 83%, and f1-score as 83%. There is increasing interest in characterizing trainees' physiological and behavioral activity profiles in a VR environment, aiming to develop better training and assessment methodologies.</p>","PeriodicalId":101458,"journal":{"name":"Virtual, augmented and mixed reality : 15th International Conference, VAMR 2023, held as part of the 25th HCI International Conference, HCII 2023, Copenhagen, Denmark, July 23-28, 2023, proceedings.
