Development of multilateral tele-control game using websocket and physics engine

In this paper, development of the force sense sharing network game using the websocket and physics engine is described. In this game, a game player can put a force on a haptic device placed at a remote location, and measured force is added to a physics engine which operates force interference calculations. At the same time, the physics engine sends back the resultant position to the haptic device in order to present the force sense to the game player. The websocket is adopted in order to realize the fast real-time two-way communications, which involves multilateral tele-control, and connect to unspecified large number of clients in the Internet. It is confirmed in the experiment using the network emulator that the position and force information coincide between the server and the client under a communication delay environment, and system is stabilized in multilateral tele-control.
