Abstract

Purpose
We developed a virtual reality (VR) endotracheal intubation training that applied 2 interaction modalities (hand-tracking or controllersIt aimed to investigatedthe differences of usuability between using hand tracking and controllers during the VR intervention for intubation training for medical students from February 2021 to March 2021 in Thailand.
Methods
Forty-five participants were divided into 3 groups: video only, video with VR controller training, and video with VR hand tracking training. Pre-test, post-test, and practice scores were used to assess learning outcomes. The System Usability Scale (SUS) and User Satisfaction Evaluation Questionnaire (USEQ) questionnaires were used to evaluate the differences between the VR groups. The sample comprised 45 medical students (undergraduate) who were taking part in clinical training at Walailak University in Thailand.
Results
The overall learning outcomes of both VR groups were better than those of the video group. The post-test scores (P=0.581) and practice scores (P=0.168) of both VR groups were not significantly different. Similarly, no significant between-group differences were found in the SUS scores (P=0.588) or in any aspects of the USEQ scores.
Conclusion
VR enhanced medical training. Interactions using hand tracking or controllers were not significantly different in terms of the outcomes measured in this study. The results and interviews provided a better understanding of support learning and training, which will be further improved and developed to create a self-learning VR medical training system in the future.
