Abstract
Recently, advancement of virtual reality technologies can provide various force sensations to users. In addition to current visual and audio display technologies, it is expected that a force display would further expand application fields of multimedia services. This study develops two haptic interfaces with 3'DOF for force telecommunication that have an orthodox parallel linkage using two kinds of actuators, this paper details the fundamental property of these devices. Further, this paper tries to reveal the relationships between human sensations and system architecture such as servomechanism in order to realize force telecommunication with reality.
