The Effects of Visuomotor Calibration to the Perceived Space and Body, through Embodiment in Immersive Virtual Reality

摘要: We easily adapt to changes in the environment that involve cross-sensory discrepancies (e.g., between vision and proprioception). Adaptation can lead motor commands so experienced sensory consequences are appropriate for new we program a movement differently while wearing prisms shift our visual space). In addition these changes, perceptual judgments of space also be altered how far I reach with my arm?). However, previous studies assessed after visuomotor adaptation, manipulation was always planar spatial shift, whereas body perception could not directly assessed. this study, investigated effects velocity-dependent (spatiotemporal) scaling distortions arm movements on perception, taking advantage immersive virtual reality. Exploiting illusion embodiment an entire body, endowed subjects spatiotemporal or 3D mappings their consequences. The results imply 2 4 times faster significantly change participants’ proprioceptive object’s size without affecting perceived ownership, although it did affect agency movements. Equivalent manipulations 11 22 degrees angular offset had significant effect size; however, mismatched information either sense ownership agency. conclude adaptation distortion similarly space, more detected.
