Cross-modal synchrony between music and visual motion modulates vection, urge to move, and comfort in VR

Sensorimotor entrainment, the spontaneous alignment of movement with external rhythms, plays a key role in how we experience music and motion. In this study, we introduce a novel method combining musical stimuli, vection, and visually induced motion sickness (VIMS) in virtual reality (VR) to investigate how cross-modal rhythmic stimulation shapes self-motion perception and comfort. In a within-subjects design with 30 participants, we manipulated auditory conditions (Music versus Silence) and VR
