Abstract: Disclosed herein are a motion-based virtual-reality simulator device and a method for controlling the same. The motion-based virtual-reality simulator device includes a virtual-reality interface for outputting virtual reality content in a form of multi-sense data that is perceptible by a user, a virtual-reality movement implementation unit including a track component for performing continuous track motion in a state in which a user gets on the track component, the track component being configured such that a slope of the track component is controlled while a surface of the track component is deformed into an even surface or an uneven surface, and an interworking control unit for outputting a control signal to the virtual-reality movement implementation unit so that a slope and a surface of the track component are deformed in accordance with the virtual reality content that is output through the virtual-reality interface.
