This study examined methods for inducing body elongation illusion in Virtual Reality (VR) environments. Experiment 1 used an avatar with an elongated finger, while Experiment 2 used an avatar with the entire hand shifted forward while maintaining its shape, to investigate the effects of differences in visual presentation methods and visuotactile congruency during object contact on the elongation illusion. Results showed that the elongation illusion did not occur with either avatar, and no effects were observed for differences in visual presentation methods or visuotactile congruency. Experiment 3 examined the effect of haptic force feedback from finger pulling. Results revealed that a pulling effect was observed when visual feedback of the avatar was absent during body position judgments, with finger length perceived as longer in the pulling direction. These findings indicate that haptic force feedback through pulling is more effective for inducing finger elongation illusions than tactile stimulation during object contact. |
