Learning through a 360° virtual reality (VR) or 2D video represents an alternative way to learn complex medical education task. However, there is currently no consensus on how best assess the effects of different learning materials cognitive load estimates, heart rate variability (HRV), outcomes, and experience in history taking physical examination (H&P) skills.The aim this study was investigate (ie, VR video) impact outcomes changes estimates HRV for H&P skills.This pilot system-design included 32 undergraduate students at academic teaching hospital. The were randomly assigned, with 1:1 allocation, group group, matched by age, sex, style. contents both videos regard visual angle self-determination. evaluated using Milestone reporting form.
