Mean and standard deviations for spatiotemporal gait parameters (WS, SL, ST) while navigating the virtual environment in the IR (purple) and HMD (green) systems. Trials featuring optic flow matched to the participant’s speed (ISO), perturbations parallel to forward motion (AP), and perturbations perpendicular to forward motion (ML) are represented with solid, striped, and cross-hatched violin plots, respectively. Each dot displays the datapoint of a singular participant. P-values for main effects and interactions are displayed on the plots, with significant values (p < 0.05) bolded, as determined by Tukey’s HSD test
