A hardware/firmware/software platform for hard real-time control over a wired or wireless network is disclosed. The platform allows the real time control of application hardware or a virtual touch device at one node (a client) of the network by another server on the network. To enable this technology, it is required that both client and server be synchronized closely, have precise sampling periods and have the ability to perform complex control computation s so that a desired effect is enabled at the client end. This invention involv es the use of GPS, or any similar method (either software or hardware) to accomplis h this precision in timing. Sophisticated prediction algorithms are used to compensate for time-varying network delays. The platform is also flexible (bilateral) in that a client can become a server, should the need arise. Thi s platform includes the use of virtual touch devices, such as a reconfigurable panel, to create GUIs which where either the client or server application hardware can be controlled. The platform can be applied to various applications such as Automated Highway Systems, telepresence, online computer games, and power system control.
