Abstract: 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.
