Pseudo-Haptics

We investigated a method for inducing pseudo-buoyancy perception when touching objects floating in liquid within a virtual environment using fluid simulation. Our findings suggest that high-precision visualization of fluid behavior and displacement of the virtual hand can provide participants with a sense of buoyancy.

The process of self-attribution during active movement was examined from the consistency of visual, somatosensory, and motor prediction information. It was shown that the recognition of the discrepancy between motor prediction and movement outcome is important for the occurrence of pseudo-haptics.
