Two adjacent left-rotating speed decomposition units are connected by one parallel transmission assembly, and two adjacent right-rotating speed decomposition units are connected by one parallel transmission assembly. The left-rotating speed decomposition units rotate together at a same speed in a same direction. The right-rotating speed decomposition units rotate together at a same speed in a same direction.

An active omni-directional motion device is provided. By combining a foot inertial sensor and a foot optical non-contact sensor, an actual moving speed and start-and-stop time are accurately judged, a user walking direction is accurately judged by a chassis magnetic angle sensor, and an active chassis actively cooperates with a user to enable the user to naturally walk on the chassis in all directions. The optimization of adaptation of the device to different heights enables the user to use the device without adjusting the device. The increase of a sitting posture function enables the user to sit down comfortably without getting off the device. The optimization of the wearing mode of a waist ring enables a user to wear a waistband more simply. The optimization of a transverse adjustment function of the waist ring enables the user to quickly adjust the waist ring to avoid biased rotation.

A system for combining six degree of freedom (6DOF) inputs, or positional and orientation inputs, from multiple 6DOF controllers in an augmented reality (AR) environment and/or a virtual reality (VR) environment is provided. In response to the detected movement of multiple controllers, and in particular, rotational movement of the multiple controllers providing user inputs in a virtual reality environment, the detected movements of the multiple controllers may be resolved to a single, common coordinate system to determine intended input to be applied to a selected virtual object in the virtual environment. The ability to resolve these inputs from multiple 6DOF controllers to a common coordinate system may provide a more natural user input mode, thus enhancing the user's experience.

Embodiments herein describe techniques for operating an omnidirectional treadmill, the techniques include receiving VR (virtual reality) topographical information comprising a VR environment, and displaying the VR environment to a user wearing a headset.
