Abstract

Realistic haptic rendering is one of the most challenging issues in the field of virtual reality. The intent is for the user to experience the same kinesthetic sensations in the virtual realm as they would in the real world. Therefore, we need to know the capabilities of the human haptic system. The issue investigated in this study was the adaptation to force feedbacks in a haptic-enabled virtual environment (VE). Psychophysical experiments are conducted to study how adaptation is influenced by changes in the force intensity and direction. The results indicate that the users definitely adapt to forces in a VE. However, the force direction and force increment/decrement do not affect adaptation. This information can be used to create haptic models with much less detail.
