Slime Hand XR: Distinct Illusory Skin Deformation in HMD Space

Slime Hand XR is an interactive head-mounted display (HMD) system that induces illusory skin deformation in VR.In the proposed system, participants wearing the HMD place their hands on a tray where a chunk of slime is visible within the HMD's view.Participants can instantly and boldly feel illusory skin stretching by looking at the deformed slime while the experimenter pinches and pulls their hand's skin at the same time.In addition, the tip of the deformed slime can be clipped with a clothespin in VR by the experimenter.Then, this setup can maintain the form of illusory skin deformation.This system adopts the principle of the slime hand illusion, which can induce a strong sense of skin deformation.By using computer-generated slime, we achieved a unique skin deformation illusion that is hard to replicate in reality, such as suspended deformation.In testing the illusion effect of this system at
