A method for replicating the terrain of a remote environment by a terrain replicator with a plurality of extendable elements is disclosed. The method includes mounting the plurality of extendable elements in close proximity on the surface of a flat stage to form a matrix of extendable elements; connecting each extendable element in the matrix to a control node in an array of control nodes, wherein each control node in the array is assigned to control one extendable element in the matrix of extendable elements; sending data of an actual physical terrain in the remote environment to a terrain analysis computer in the terrain replicator; converting the remote terrain data by the terrain analysis computer into a terrain-generating data stream for driver electronics; producing by the driver electronics a plurality of control signals from the terrain-generating data stream, wherein each signal in the plurality of control signals addresses a control node in the array of control nodes to extend or retract each extendable element in the matrix of extendable elements; and generating by the matrix of extendable elements a topography precisely corresponding to the topography of the actual physical terrain at the remote environment.

An omnidirectional treadmill environment simulator is disclosed. The omnidirectional treadmill environment simulator includes a circular simulator stage area, a plurality of transport mechanisms that maintain an object at or near the center of a circular simulator stage area and at least one processor. The processor is configured to collect position data of the object and process the position data to control the transport mechanisms. Also included is a receiver for receiving data from a remote location and a terrain analysis computer for processing the data received from the remote location. The terrain analysis computer collects the data received from the remote location to form an accurate simulation of an upcoming condition at the remote location. The omnidirectional treadmill environment simulator includes a transmitter for transmitting the position data to a remote location.

Disclosed is a device (1) for moving in virtual reality including a substantially rigid node (4) and an envelope (5) arranged so as to be capable of movement in all directions about the node (4), the envelope (5) defining with the node (4) a surface for the movement of a person (2), and the assembly defined by the node and the envelope bearing on an appropriate bearing element (6). The envelope can be mounted so as to slide against the node, or at least a portion of the node.
摘要:
An apparatus that is capable of omni-directional movement has been developed. The device includes a belt layer made of a plurality of interlocking flexible rings and a surface layer made of a laterally inelastic and longitudinally flexible material that surrounds the exterior of the belt layer. The device has a bladder located in the interior of the belt layer that provides structural support for the belt layer and surface layer and a hub that is in contact with the surface layer and is connected to an axle. Longitudinal motion occurs as the bladder, the belt layer, the surface layer, and the hub rotate together. Lateral motion occurs as the belt layer and the surface layer rotate around the bladder. Longitudinal motion is induced by a plurality of electromagnetic curvilinear motor drive rings that are located around the hub and are in contact with the surface layer.

A virtual reality system transposes a user's position and movement in real space to virtual space. The virtual reality system includes a locomotion interface that outputs signals indicative of a user's position in real space. The locomotion interface includes a pressure-sensing mat having a base layer, a plurality of pressure sensing elements formed over the base layer, and a top layer formed over the plurality of pressure-sensing elements, and a base around which the pressure sensing mat is disposed, the pressure-sensing mat being freely moveable about the base. The plurality of pressure sensing elements output a signal indicative of pressure applied to the top layer. A virtual reality processor uses the signals output by the locomotion interface to produce an output indicative of the user's position in the virtual space corresponding to the user's position and movement in the real space. A display uses the output from the virtual reality processor to produce an image of the virtual space.

摘要:
A device for walking or running in place, especially for virtual spaces in which two transport elements crossing each other at a right angle are provided, which together form a walkable central surface, on which a user walks forward, whereas, under him, the transport elements move at the same speed. It is essential that the transport elements consist of rows of square plates or tiles, which can be moved in rows in the X and Y directions, where at all times a row of tiles is removed by a transfer device and then shifted by 90° or 180°.
