Learning and Usability within a Virtual Reality Trainer for Medical Students

Abstract

Virtual reality (VR) offers the potential to train medical students on high-risk situations. The current study investigated VR training of medical students to diagnose and treat a patient avatar experiencing a serious head injury. The user interface was investigated, including use of tools, comfort and VR locomotion, and found to be sufficiently high to warrant training within a medical curriculum. In addition, actual learning as a function of VR training was assessed by comparing medical students' knowledge structures to an expert knowledge structure before and after training. Students' knowledge structures became more similar to an expert's knowledge structure indicating that their conceptual understanding of core head-injury concepts increased as a result of VR training. The study was carried out under the auspices of Project TOUCH (Telehealth Outreach for Unified Community Health), a multi-year collaboration between The University of Hawaii (UH) and The University of New Mexico (UNM).
