Haptic displays serve great importance in creating the immersiveness sense that block virtual reality (VR) users from the contradictory impressions from the real world. We introduce the general structure of virtual reality systems. It reports common approaches in constructing different virtual scenarios and the way they are utilised. We integrate a motion platform with an application program interface (API) based virtual environment authoriser to provide force feedback for simulating inertia related applications such as virtual gliding, driving, and snowboarding.
