A balance training system includes a moving carriage moving on a moving surface by driving a driving unit, and calculates a load's center of gravity of the training person's feet on a boarding surface from the detected load. The system sets a stable range. The stable range is a range of the load's center. The training person is estimated to maintain upright on the boarding surface in the range. The system controls movement of the moving carriage in a mode selected between a first mode and a second mode. In the first mode, the driving unit drives under drive control predicting that the calculated load's center shifts within a first range set inside the stable range. In in the second mode, the driving unit drives under drive control predicting that the calculated load's center shifts to a second range set outside the first range inside the stable range.

A VR (virtual reality) omni-directional exercise machine with a terrain environment simulation function is provided. The VR omni-directional exercise machine includes a protective ring, a protective ring supporting rod, a protective ring supporting column, an exercise platform, a control machine, and VR head-mounted display, wherein the protective ring is arranged above the exercise platform and is connected to the protective ring supporting column through the protective ring supporting rod, and the bottom of the protective ring supporting column is fixedly connected to the outer side of the exercise platform; a moving vertical rod module lattice is arranged in the exercise platform, the moving vertical rod module lattice and the VR head-mounted display are both connected to the control machine, and the control machine is used to coordinate and control the movement of the moving vertical rod module lattice according to an terrain environment displayed in the VR head-mounted display.

A haptic simulation exercise device includes a frame, a contact point supported by the frame, and an actuator. The contact point is configured to allow user contact with the exercise device during use of the exercise device. The actuator is configured to displace the contact point relative to the frame.

In particular embodiments, a treadmill may comprise one or more lifting mechanisms configured to lift and lower a treadmill belt (e.g., adjust an angle of the treadmill belt relative to a support surface) by adjusting a height of the front and rear of the treadmill about a pivot point. In particular embodiments, the pivot point may be positioned somewhat centered along a length of the belt. In particular embodiments, a seesaw arrangement may provide a central pivot point, providing a moment arm to the motor while decreasing a moment arm caused by the load (e.g., a runner). In this way, an apparent load on a motor providing incline and decline to the running surface may be reduced.

The present invention relates to a virtual golf device and a virtual sports device. The virtual sports device comprises a play area in which a user who plays virtual sports is located, a display area in which a content image is displayed, and an image providing unit for projecting the content image onto the display area to provide the content image to the user.

A virtual reality (VR) system includes a VR display and a VR movement apparatus that includes hand user interfaces (UIs) and foot UIs that can support the hands, feet, seat, and total weight of a user. The VR movement apparatus allow the user's hands and feet to move in 3-dimensional space that include vertical, lateral, and fore-aft direction movements. A computer running VR software coordinate and synchronizes the VR movement apparatus and the VR display to provide system users with simulated activities in a VR environment.

An annular multimedia stadium goalpost and multipurpose target display system. The system includes a rear support-and-multimedia assembly for supporting the net and producing audible and visual effects. The system also includes a at least one annular frame and a primary projector. The rear support-and-multimedia assembly includes a support assembly and a multimedia bar system. The support assembly maintains the annular frame and the multimedia bar system in an orientation that facilitates playing sports and projecting information. The multimedia bar system includes a plurality of lights, a plurality of first speakers, a plurality of sponsor display panels, a retractably screen assembly, and a retractably underground projector in order to audible and visually convey content regarding the sports game and advertisements to the audience. The system also includes an annular display, and a multitude of rangefinder laser-detector video cameras to track, record, and present gameplay live.

The present invention relates to a golf swing platform linked to a virtual golf course, and may independently drive a swing-stage part and a hitting part of the platform, and the inclination information may be calculated from terrain information of an area corresponding to the swing-stage part and the hitting part of the platform based on a position where a virtual ball is placed on the virtual golf course, and the swing-stage part and the hitting part may be controlled to be driven, respectively.

A display apparatus includes a display; a remote controller; a controller. The controller is configured to receive a first command for fitness training, cause the display to present one or more modes including a follow-up mode and an exercising-while-watching mode for selection; in response to selection of the follow-up mode, cause the display to show a first window and a second window disposed on a first user interface for receiving a focus move command from the remote control, with the first window displaying a first video associated with fitness training and the second window displaying a second video associated with image data from a camera; receive a volume adjustment command; in response to the focus being on a volume control for the first or second video, adjust a volume of the first or second video in response to the volume adjustment command. A method for controlling the apparatus is disclosed.

A processing system including at least one processor may obtain at least one video of a first competitor along a competition route in a physical environment, obtain data characterizing at least one condition along the competition route as experienced by the first competitor, present visual data associated with the at least one video to a second competitor via a display device, and control at least one setting of at least one device associated with the second competitor to simulate the at least one condition, wherein the at least one device is distinct from the display device.
