Position and Rotation Precision in VR
Testing conditions
In the rapidly evolving field of virtual reality, precise motion tracking is crucial for immersive experiences. This study presents a comprehensive benchmark comparison of position and rotation precision across leading VR systems: HTC Vive 2, Oculus Quest 2, Quest Pro, HP Reverb G2, and our proprietary motion tracking technology.
Our research team conducted controlled tests in a laboratory environment to evaluate the performance of these systems under conditions typical of entertainment applications. To ensure accuracy, we used a freshly calibrated 6-camera OptiTrack system as our reference point. Our own tracking algorithms were implemented on an unmodified Qualcomm XR2 reference design ("Morpheus") hardware, allowing for a fair comparison with commercially available solutions.
This benchmark aims to provide developers, researchers, and VR enthusiasts with valuable insights into the current state of motion tracking technology across popular platforms.
