ABSTRACT:
An input system for a virtual reality application that allows for natural human locomotion, and method of using the same, consists of a sphere having a center and an exterior surface and a base support supporting the sphere on the base support. A low friction interface is formed between the base support and a portion of the exterior surface of the sphere. The low friction interface generally conforms to the portion of the exterior surface of the sphere and permits rotation of the sphere about the center of the sphere relative to the base support. A user support is rigidly secured above the sphere and supports a user on the exterior surface of the sphere and holds a center of mass of the user on a vertical axis passing through the sphere. And one or more sensors are coupled to the base support for detecting and measuring a movement of the sphere. Furthermore, a restraining harness is rotatably attached to the user support, wherein the restraining harness rotates about the vertical axis passing through the sphere. The restraining harness and user support are adapted to hold a user on the vertical axis passing through the sphere.
