The Effect of Habituation on Pseudo-Haptics to Manipulate Weight Perception

Abstract

Pseudo-haptics, one of the cross-modal illusions between visual and haptics, can display various haptic sensation only by modifying visual stimuli. On the other hand, the decline of the illusion effect by long term experience of the illusion was found in size weight illusion, which is also a cross-modal illusion between visual and tactile senses. However, the possibility of declining pseudo-haptics effect made by habituation has not been concerned when designing virtual reality (VR) experiences with pseudo-haptics. Thus, in this paper, we constructed a experiment to verify the presence or absence of habituation, by presenting pseudo-haptics which manipulate weight perception over a long period of time. The result of study showed that the effect of pseudo-haptics, which made the object feel heavier than the actual one, decreased. From this fact we indicated that long term experience of pseudo-haptics which manipulate weight perception reduces its illusion effect.
