Abstract: This invention is a device which allows for a full range of motions from a users upper and lower body for the purpose of enhancing a virtual simulation. The purpose of this device is to allow users to run both foreword, backwards, and side-to-side, and to allow the user to jump, crouch, prone, twist and turn while remaining centered over a control pad. The devices supports the user via the user's back allowing the user to perform any of the mentioned movements without having to hold onto any means of support with their hands. Any of the user's movements can be superimposed into a virtual scenario such as a video game, tactical simulator, physical fitness training software, etc. The invention includes a vest that attaches to the base on the user's back. This vest is highly adjustable allowing for a snug fit on the user for stability. The base itself consists of a floor piece that not only interprets the users footsteps but also can be manipulated by software to simulate a wide variety of terrains.
