Abstract
Recently, the advancement of virtual reality technologies can provide various force sensations to users. With regard to studies on the haptic interface, most researchers have focused on the development of the haptic interfaces. So, these devices are constructed by using several decelerators. It is supposed that various types of decelerators individually cause the different effects on in the force/position display performance ; it may also affect human force sensation. Then, in this study, we developed haptic devices with four types of decelerators and compared their force/position display performances. Further, this paper attempts to how the decelerators affect human force sensations when employing haptic devices.
