A Virtual Reality Application of the Rubber Hand Illusion Induced by Ultrasonic Mid-air Haptic Stimulation

Ultrasonic mid-air haptic technologies, which provide feedback through airwaves produced using ultrasound, could be employed to investigate the sense of body ownership and immersion in virtual reality (VR) by inducing hand illusion (VHI). perception has solely been investigated for glabrous (hairless) skin, higher tactile sensitivity than hairy skin. In contrast, VHI paradigm typically targets skin without comparisons The aim this article was illusory ownership, applicability ultrasonic haptics, perceived VR VHI. Fifty participants viewed a being stroked feather synchronously asynchronously with stimulation applied on palmar surface dorsal their hands. Questionnaire responses revealed that synchronous induced stronger asynchronous stimulation. conditions, also as more intense compared surface. Perceived not related per se but enhanced provision
