Abstract: A VR walking mechanism includes a first pedal, a second pedal, a sensing device, a control device and a driving device. The first pedal and the second pedal are connected to the driving device, respectively. The sensing device is configured to obtain motion information of a first object and/or a second object and send the motion information to the control device. The control device determines a predicted landing point of the first object and/or the second object based on the motion information and controls the driving device according to the predicted landing point so as to drive the first pedal and/or the second pedal to move to the corresponding position. The first pedal and/or the second pedal resets after sensing that the first object and/or the second object has stepped thereon. A VR walking method corresponding to the VR walking mechanism is further provided.

Abstract: A smart wearable apparatus, smart wearable equipment, and a control method of the smart wearable equipment are provided. The smart wearable apparatus includes a rigid body, at least one hinge mechanism, a brake and a controller. The hinge mechanism is arranged on the rigid body, and the hinge mechanism includes a first pivot portion, a second pivot portion, and a pivot arranged between the first pivot portion and the second pivot portion. By means of the hinge mechanism, two portions of the rigid body, which are connected, respectively, to the first pivot portion and the second pivot portion of the hinge mechanism, can pivot relative to each other in a first direction. The brake is connected to the hinge mechanism, and the brake can receive a first control signal from the controller to stop the hinge mechanism, thereby stopping the two portions of the rigid body from relatively pivoting.
