VR / AR Tracking Systems for Vehicles, Motion Simulators and Large Spaces
LPVR is LP-Research’s tracking software for virtual, augmented and mixed reality headsets in places where a headset’s built-in tracking fails: inside a moving car, aircraft or motion simulator, in tracking volumes far larger than a room, and in multi-user installations that must share one coordinate system. Every LPVR system fuses an inertial measurement unit on the headset with an optical outside-in tracking system such as ART, OptiTrack or VICON, and predicts head motion so that the rendered image arrives without perceptible latency. The result is sub-millimetre position, 0.2° orientation and update rates of up to 1000 Hz, delivered to Unity, Unreal, Autodesk VRED and any SteamVR or OpenXR application through a standard driver. Supported headsets include Varjo XR-3 and XR-4, Meta Quest 3, Apple Vision Pro, Xreal Air 2 Ultra and One Pro, HTC Vive Focus Vision and Pico 4 Ultra. New to the topic?

Which LPVR product do I need?
- Headset users walk around a large space, several at once: LPVR-CAD with a wired PC headset, or LPVR-AIR when the headsets must be wireless.
- The user sits in a car, a truck cabin, a helicopter or on a motion platform: LPVR-DUO, which separates head motion from vehicle motion so the cockpit stays put while the world outside moves.
- Virtual content must be anchored to real streets, not just to the car: LPVR-DUO plus LPVR-POS, which tracks the vehicle’s own pose in world coordinates.
- Mixed reality with video passthrough: LPVR-CAD with Varjo XR-4 or LPVR-AIR with Meta Quest 3, both with optical markers for repeatable overlay alignment.
- Vehicle localization for a test bench or simulator without any headset: LPVR-POS on its own.
What you receive
Each LPVR system ships with a licence dongle (or an online licence for LPVR-POS), 3D-printed marker holders for the supported headset and controllers, the LPMS hardware the product needs (a vehicle-fixed IMU for LPVR-DUO; GNSS receiver, CAN interface and IMU for LPVR-POS), accessory cables and a one-year maintenance contract with software updates. Integration with your optical tracking system, headset and engine is documented in the LPVR documentation portal. Pricing is per installation: contact us with your headset, tracking system and use case, and we will propose a configuration and, where useful, a pilot setup.
