A seating device for connection to a movement mechanism includes at least one seat and a fastening flange. The fastening flange has at least one flange clamping receptacle, and the seat has at least two seat clamping receptacles for connection to the fastening flange. At least one clamping device is provided, which extends in the direction of a clamping axis. The flange clamping receptacle is arranged in the direction of the clamping axis between two of the at least two seat clamping receptacles. The clamping device passes through the two seat clamping receptacles arranged on either side of the flange clamping receptacle and clamps them together in the direction of the clamping axis.

VR amusement ride device that enables a user viewing virtual reality images to enjoy the feeling of riding a horse or vehicle by having the user ride a machine at the same time as viewing images, thereby preventing VR motion sickness. The VR amusement ride device includes VR image viewer, image processor, seat structure, and seat structure controller. The seat structure includes a saddle, a base, and a tilt angle adjuster, and the saddle rocks continuously or intermittently about a central axis. The image processor records/stores VR image data and event data in memory, transmits the VR image data to the VR image viewer and transmits event information based on the event data to the seat structure controller. The seat structure controller varies tilt angle of the rocking central axis of the saddle to forward tilt, backward tilt, right tilt, and left tilt on the basis of the event information.

The swinging apparatus includes a base, a support located above the base, a coupler disposed between the base and the support and including a universal joint, and linear actuators disposed between the base and the support. Each of the linear actuators includes a first end and a second end located on an opposing side to the first end. The first end is mechanically connected to one of the base and the support. The second end is configured to freely move touching a surface of the other of the base and the support.

An amusement ride is formed from a self-equalizing dual line affixed to a pulley at its upper end and to pulley and counterweight system at its lower end. An upper platform at the upper dual line end launches a rider who is connected via a line to a pulley riding on the dual line. A slide is carried by the upper platform from which the rider is launched, resulting in the rider swinging in an arcuate motion about the pulley. A belay, carried by the dual line, is movable to confront the pulley as the rider is carried down the dual lines and to enhance the arcuate swinging of the rider. A lower landing permits the rider to demount the amusement ride.

In one aspect, the disclosure features methods for estimating a vestibular function of a subject. The methods include moving the subject along a first direction parallel to the direction of gravity, receiving a first input set from the subject, the first input set indicating the subject's perception of the first direction, and estimating a first parameter related to a first vestibular function of the subject based on the first input. The methods further includes changing an orientation of the subject with respect to the earth, moving the subject along a second direction after changing the orientation of the subject, and receiving a second input set from the subject, the second input set indicating the subject's perception of the second direction.
