The Effect of the Virtual Object Size on Weight Perception Augmented with Pseudo-Haptic Feedback

Providing realistic haptic feedback of virtual objects is critical for immersive VR experience, and there have been many approaches using proprioception mismatch to provide pseudo-haptic feedback. Most of them, however, are limited in that the differences in visual features of the objects are not considered in adjusting the level of pseudo-haptic feedback. Therefore, we conducted an experiment to examine how the threshold of simulated weight perception changes according to the size of a virtual object. The results showed that a stronger level of visual pseudo-haptic feedback is required for bigger objects for simulated weight perception.
