LPVR-CAD is a location-based VR tracking system. Consumer virtual reality head mounted display (HMD) systems such as the HTC VIVE or Valve Index support so-called room scale tracking. These systems are able to track head and controller motion of a user not only in a sitting or other stationary position, but support free, room-wide motions.
The volume of this room scale tracking is limited to the capabilities of the specific system, usually covering around 5m x 5m x 3m. Whereas for single user games or applications this space may be sufficient, especially multi-user, location-based VR applications such as arcade-style game setups or enterprise applications require larger tracking volumes.
Optical tracking systems such as ART offer tracking volumes of more than 15m x 15m x 3m. Although the positioning accuracy of optical tracking systems are in the sub-millimeter range, especially orientation measurement is often not sufficient to provide an immersive experience to the user. Image processing and and signal routing may introduce further latencies.
Our location-based AR/VR tracking system solves this problem by combining optical tracking information with inertial measurement data using a special predictive algorithm based on a head motion model.
