A system for a virtual and mixed-reality enhanced exercise machine that allows a user to exercise while interacting with a virtual reality or mixed reality environment using whole body movements and positioning, and receiving haptic feedback associated with the user's interaction with the virtual reality or mixed reality environment.

Provided is a treadmill including a frame structure supporting both ends of each of a plurality of slats to allow the plurality of slats to be movable. The frame structure includes a first frame and a second frame arranged parallel to each other with a distance therebetween, a first side frame and a second side frame respectively arranged outside the respective first and second frames, and a plurality of horizontal bars having a length greater than the distance. Each of the plurality of horizontal bars includes a first load region between the first frame and the second frame, a second load region overlapping the first side frame and fixed to the first side frame, and a third load region overlapping the second side frame and fixed to the second side frame.

Provided is an exercise guide system. The exercise guide system guides a user in an exercise on a treadmill, of which the speed is controllable according to the user's free will. The exercise guide system includes an input unit configured to receive at least one target exercise speed, a detection unit configured to detect an actual exercise speed of the user on the treadmill. The exercise guide system further includes an exercise guide unit configured to provide information related to the actual exercise speed and the target exercise speed so that the user personally adjusts an exercise speed on the treadmill.

Disclosed is an omnidirectional treadmill which has several connected belt units with supporting frames and endless belts which are moved revolving in the first spatial direction. In the second spatial direction, the endless belts of the belt units are moved. The endless belts are driven in the second spatial direction preferably by gear wheels mounted on rolls and by a toothed shaft. The movement of all endless belts is synchronized by coupling with special tooth form crown gears arranged between the belt units.

A slat-belt treadmill is provided. The slat-belt treadmill includes a treadmill frame, a front shaft pivotally coupled to the treadmill frame, and a rear shaft pivotally coupled to the treadmill frame; a plurality of slats constituting a slat-belt, collaboratively rotating about the front and rear shafts, and forming an exercise surface on which a user of the treadmill may walk or run; a driving apparatus coupling to the slats and driving the slats to rotate about the front and rear shafts; and a light-emitting unit disposed under the exercise surface to provide a light source. When the slats are rotating, light from the light-emitting unit is intermittently visible as the slats intermittently block and reveal the light.

An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

A treadmill is provided. The treadmill includes a frame; a first side support coupled to and extending substantially vertically upwards relative to the frame; a second side support coupled to and extending substantially vertically upwards relative to the frame; and a handrail assembly having a first side coupled to the first side support and a second side coupled to the second side support, each of the first and second sides of the handrail assembly comprising upper and lower members vertically spaced from one another and front and rear push members spaced apart from one another along a longitudinal length of the treadmill, the front and rear push members coupling the upper and lower members, and collectively providing a plurality of hand placement positions including at least two substantially horizontally aligned hand placement positions and at least one primarily vertically aligned hand placement position.

A device for visual walking includes an omnidirectional exercise machine and foot wearable devices. A method for visual walking is applied to the device for visual walking. When a user wears the omnidirectional exercise machine and uses the loading frame to adjust a height of the omnidirectional exercise machine, and wears the foot wearable devices to stand and run on a running plate, human body posture data is obtained by tracking a human body torso. Then displacement data of left and right feet is obtained by tracking the feet. A virtual position and a movement speed of the feet are respectively obtained according to the displacement data, the leg posture is inferred by the IK algorithm according to the virtual position and the walking action of the virtual character is controlled according to the human body posture data, the movement speed of the feet, and the leg posture.

A motion device for a virtual reality interaction includes a core, a running belt carried by the core and a frame. The running belt is configured to wrap the core and capable of sliding on the outer surface of the core. The running belt includes a number of running belt units. A surface of each running belt unit facing the core is provided with a number of grooves, and each groove of each running belt unit is connected with a corresponding groove of an adjacent running belt unit through an elastic strap. The frame is located at a periphery of the running belt and is configured to carry the running belt and the core. A number of first balls are arranged between the frame and the running belt.

A treadmill includes a frame, a front shaft assembly coupled to the frame, a rear shaft assembly coupled to the frame and spaced apart from the front shaft assembly, a running belt disposed about the front and rear shaft assemblies, and a motor coupled to the running belt. In a first operating mode of the motor, the force of rotation of the running belt is provided by a user of the treadmill. In a second operating mode of the motor, the force of rotation of the running belt is provided by the motor.
