A wearable visualization device includes a housing, one or more lenses coupled to the housing and configured to display virtual features for visualization by a user of the wearable visualization device, and a cover coupled to the housing and configured to adjust between an extended configuration in which the cover extends over at least a portion of the one or more lenses and a retracted configuration in which the cover does not extend over at least the portion of the one or more lenses. The wearable visualization device also includes a controller and one or more sensors. The controller is configured to receive sensor data from the one or more sensors and to provide control signals to an actuator to adjust the cover between the extended configuration and the retracted configuration based on the sensor data.

A virtual experience device that enables experiencing a feeling of falling includes an instrument in which a rotation support portion that rotatably supports a flat plate is formed, and a VR headset including, in the inside, at least a height sensor and a display that performs display on a virtual space. The VR headset includes the sensor that detects a second state of when a height from a floor surface on which the instrument is installed is equal to or less than a predetermined height. Further, the virtual experience device includes video software including a stop video and a falling video switched from the stop video when the second state is established.

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.

A system for transporting passengers has a drive unit and a vehicle that is pulled by the drive unit. The drive unit includes a stationary guiding device like a rail which is arranged laterally at a distance and above at a height relative to the vehicle. The drive unit also includes a bogie which is movably attached to the guiding device. A connection unit couples the bogie to the vehicle by a joint, so that drifting of the vehicle is possible.

An attraction system includes an arm having a first end and a second end, a passenger vessel coupled to the first end of the arm and configured to receive at least one passenger, a fulcrum engaged with the arm and disposed between the first end of the arm and the second end of the arm, and a counterweight disposed on a segment of the arm between the second end of the arm and the fulcrum, wherein the counterweight is movable across the segment of the arm. A vehicle of the attraction system is coupled to or integrated with the fulcrum, and the vehicle is configured to be moved along a vehicle path.
