仮想環境での動的把持における振動グローブを用いた力分布の提示

抄録

In recent years, the use of virtual environments has attracted attention in various tasks such as education and development. Grasping movements are frequently performed in work, and changes in the force distribution of the hand appear due to the use of tools and the maintenance of a stable posture. In this study, we focus on a vibrotactile glove, which is small, lightweight and can present tactile sensations to various parts of the hand, and propose a vibration presentation referring to the force distribution in an actual dynamic grasping motion. For this purpose, we measured the force distribution during an actual swinging action of a stick and presented several vibration patterns when performing the same action in a virtual environment. We then conducted a questionnaire for each vibration pattern and investigated whether the vibration presentation considering the force distribution is suitable for the expression of dynamic grasping.
