Using Vertex Displacements to Distort Virtual Bodies and Objects While Preserving Visuo-Tactile Congruency During Touch

Distorting virtual bodies during virtual body illusions is a key element in several fields of basic research and clinical applications. This technique typically results in a loss of visuo-tactile congruency during touch, which is concealed by restrictions in participant movement. We present a method based on vertex displacement which allows to preserve visuo-tactile congruency during touch while more freely moving a visually distorted virtual body and/or object.
