LPVR-AIR: Wireless location-based AR/VR Tracking Solution for Immersive 3D Visualization
Overview
LPVR-AIR provides all the features of the LPVR-CAD system, along with the added advantage of wireless streaming of image data from a SteamVR application such as Autodesk VRED to the Meta Quest 2 or Pro.
LPVR-CAD is a location-based VR tracking system that supports room-scale tracking. These systems can track not only the head and controller motion of a user in a stationary position but also support free, room-wide motions. However, for multi-user, location-based VR applications such as arcade-style game setups or enterprise applications, larger tracking volumes are required.
LP-Research’s FusionHub software, in combination with the open-source application ALVR, provides a perfect solution for this. By default, ALVR uses Meta Quest’s internal inside-out tracking for pose calculation. With LPVR-AIR, Quest’s native inside-out tracking is replaced with combined IMU and ART/Optitrack outside-in tracking, enabling simultaneous, spatially synchronized operation of multiple HMDs in large tracking volumes.
To make FusionHub’s tracking functionality available to standalone augmented and virtual reality headsets, it is integrated with Android-compatible OpenXR HMDs, using a customized version of the ALVR open-source project. ALVR enables wireless streaming of imagery from a host computer and interfaces with 3D content engines through SteamVR. While the original ALVR client was built to work with Meta Quest HMDs, ALVR works with any OpenXR compatible headset.
