Definitions

  • aspects of the disclosure are directed to virtual reality systems and, more particularly, to a virtual reality system and apparatuses associated therewith.
  • Interactive virtual reality experiences often employ and track physical props and other tracked objects, such as the user themselves, to heighten the level of immersion experienced by the user. Because of this tracking requirement, the actual interaction of the user with the VR scene or movement of the user within the VR scene is often constrained to a limited theater stage. Accordingly, many virtual reality experiences can occur at a venue having a limited footprint. However, within that limited footprint, size and configuration requirements for the stage may vary considerably.
  • the stage may have various equipment attached thereto or otherwise engaged therewith to provide environmental effects during a VR scene.
  • Such effects equipment may include, for example, fans, water dispensers (e.g., misters), scent dispensers, transducers (e.g., shock and vibration transducers), heat and/or cold emitters.
  • the arrangement of the effects equipment may also include for example, solenoid valves, linear actuators, or other devices arranged to actuate or cooperate with any of the effects equipment to produce the desired effect.
  • the user(s) involvement within the scene often requires movement on or about the stage.
  • a tracking system streams the position and orientation of every tracked object to a simulation process so that the virtual representations of the tracked objects can be correctly rendered as part of the virtual reality environment.
  • a tracking system follows the position and orientation of a head-mounted display being worn by the user so that the viewpoint of the user in the virtual reality environment can be rendered correctly on the display screens of the head-mounted display.
  • More complex systems include tracking of secondary and tertiary objects, allowing the user or multiple users to experience more complex virtual reality environments.
  • One such method of tracking physical objects in virtual reality systems is the use of optical cameras to track the physical objects.
  • the physical props can be imaged by the cameras arrayed around the physical installation (e.g., stage).
  • the images captured by the cameras facilitate the determination of the position and orientation of each physical object or prop by comparing the view of the object as seen by all cameras having the physical object in view (e.g., by triangulation).
  • the tracking method implementing optical cameras to track the physical objects is that, in order to provide optimal tracking, the optical cameras should be as unaffected by shock and vibration as possible.
  • the tracking device(s), such as optical cameras and/or the like are isolated from shock/vibrations associated, for example, with users moving on or about the stage and/or effects equipment being actuated or de-actuated during the VR scene.
  • the stage/staging supporting the VR scene prefferably expandable or configurable in size/shape (e.g., modular), in compliance with the requirement for substantially isolating the tracking device(s) from shock/vibration, in order to meet the requirements of different VR scenes, or to be readily customizable and conformable to the space afforded in a physical installation of the VR theater system (i.e., customizable to the footprint of the building housing the VR theater system).
  • Such an arrangement includes a stage defining an experience platform and a tracking support structure having a tracking device mounted thereto.
  • the tracking device is arranged to be vibration- isolated from the stage and to track an object within the experience platform.
