This study investigated whether weight illusions in virtual reality (VR) without haptic feedback occur as the real world. In experiment, we set up three scenarios to cause different VR: size–weight illusion (smaller objects look lighter but feel heavier than larger ones), brightness–weight (brighter darker and material–weight (lighter-looking materials, such wood, heavier-looking metal). The experimental results indicated that perceptions of VR were opposite those However, perception was...
