Abstract:
1. A portable locomotion platform device lacking handles or anything for a user to grab onto with hands, the locomotion platform device permitting a user to walk, or run, crouch, jump or change direction, and continue these motions without impediment, while remaining constrained to the area of the device, the device comprising: a platform with an upward facing, essentially spherically concave continuous surface upon which the user stands while performing the motions, wherein said essentially spherically concave surface has a radius about the distance from a base of a user's foot to the user's hip joint; the concave surface of the platform being a low friction, fixed surface, firm enough to support a user's weight without substantial deformation; means for reducing the friction of a user's feet contacting the surface of the platform sufficiently to allow omni-directional motion, wherein the means for reducing friction is selected from the group consisting of wax, polish, lubricant, and polytetrafluoroethylene; wherein the user does not move substantially away from a center of the platform as the user moves their feet; and a brace connected to and surrounding an underside surface of the platform in order to prevent movement of the platform during use.
