summary

A controlled experiment with 22 participants measures effects of unnoticeable hand redirection in VR using the joint position reproduction (JPR) method: after about 10 minutes of redirected hand-reaching, proprioceptive accuracy declines significantly, indicating unconscious recalibration to the offset. Five one-to-one visible hand reaches partially restore accuracy but do not return it to baseline, suggesting prolonged exposure to visual–proprioceptive offsets can produce lingering aftereffects and motivating exploration of transitional interfaces or other countermeasures.
