Predicting the limits: Tailoring unnoticeable hand redirection offsets in virtual reality to individuals' perceptual boundaries

Many illusion and interaction techniques in Virtual Reality (VR) rely on Hand Redirection (HR), which has proved to be effective as long as the introduced offsets between the position of the real and virtual hand do not noticeably disturb the user experience. Yet calibrating HR offsets is a tedious...
