Verification of the Effect of the Difference in Posture between Real Space and VR Space on the Experiencer, Focusing on the Experience of Falling

In recent years, research aimed at enhancing the sense of immersion in VR environments by inducing human sensations within VR spaces has been actively conducted. This study focuses on the sense of falling, examining the pitch angle direction's rotation angle and angular velocity, as well as the impact of the timing of rotations between the VR space and the real world on the sense of falling. Specifically, the study aims to clarify how adjusting the timing of rotations in the real world relative to the timing of falling rotations in the VR space affects the sense of falling.
