Computer-based systems provide a wireless, high fidelity, real-time video and audio immersive environment for multiple users. A user may be equipped with a head mounted display device which wirelessly receives real-time video signals transmitted by a radio transceiver linked to a computer that generates the real-time video images. Aspects include body, arm and leg motion and orientation sensors in wireless communication with a radio transceiver linked with a computer. Video images may be generated using a portable array of user dedicated computers controlled by a single computer that is controlled by an operator.
