Author van Lit, Casper (TU Delft Mechanical, Maritime and Materials Engineering) Contributor Abbink, David (mentor) Boessenkool, Henri (mentor) Verlinden, Jouke (graduation committee) Degree granting institution Delft University of Technology Date 2018-04-30 Abstract The Rubber Hand Illusion is an illusion in whichvisual cues of stimulation on a fake hand are combined withsynchronous tactile cues on a participant’s hand, which caninduce a sense of bodily ownership of the fake hand. Thistechnique does not facilitate synchronous movement of thehands, and asynchronous stimulation or movement can break theillusion, thereby limiting potential benefits that bodily ownershipmay have in practical applications such as telerobotic control.This study aims to quantify to what extent a Virtual Realityheadset with hand tracking capabilities can be used to evoke arubber hand illusion, and to what extent the illusion strengthmaintains during voluntary hand movement. Twelve subjectswere randomly presented with three conditions; the classic RubberHand Illusion (RHI), serving as a baseline for comparison,the static Virtual reality Rubber Hand Illusion (VRHI), thevirtual reality equivalent of the original experiment, and themoving Virtual reality Rubber Hand Illusion (mVRHI), whereparticipants’ voluntary hand movements were tracked usingmotion controllers, to generate simultaneous virtual hand motion.Illusion strength was quantified subjectively, by a 27-questionquestionnaire adapted from literature, and objectively, by measuringproprioceptive drift; the distance between perceived handlocation and actual hand location. It was hypothesized that VRHIand mVRHI would increase the strength of the illusion, comparedto RHI. A significant increase in proprioceptive drift was foundbetween the RHI and VRHI conditions. Questionnaire scoresin the ownership category were significantly higher for VRHI,and the control category showed higher scores for mVRHI. Inconclusion, a higher embodiment was achieved during VRHI, butmVRHI did not improve upon VRHI as expected.
