Virtual Realityにおける視野と頭部運動の同期および聴覚刺激の位置情報が交差-反発運動刺激の識別に与える影響

Head-mounted displays (HMD) have a variety of features that differ from those of conventional devices, and these features enable a more realistic experience. However, the effects of the unique features of HMD on human perception are still unknown. In this study, we examined the effects of synchronizing Fielf of view and head movement with auditory stimulus Localization on discrimination in VR. In the experiment, participants were asked to discriminate spherical motion (stream/bounce) in VR. The results showed that synchronization of visual field and head movement enhanced discrimination sensitivity and that the presentation of auditory stimulus altered the perception of spherical motion, but its positional information does not affect the perception of spherical motion. Synchronization between visual field and head movement was found to compensate for motion-induced blurring during discrimination and to improve discrimination sensitivity but did not affect the level of judgment.
