Just for reference, Quest pro has 5 cameras for position tracking, 3 for face, and 6 for the two controllers (3 each). Complete full body tracking would probably require some more in the controllers. Assuming inside out tracking, redundancy is required, since you can make the majority of the cameras useless by standing in the corner of a room with white walls. Features are required for tracking. Maybe the future is LiDAR, or something new, or old (military gets along with IMUs).

Ah, so we're talking specifically about inside out tracking without lighthouses. In that case the camera duplication makes that number make sense, but it could have used more elaboration.

  > without lighthouses Well, we're talking about the future. The Quest 2 implementation proved that the future is definitely not lighthouses [1], especially for mobile, which is the neccesary future of AR. Lighthouses are a technology from a time when there were no SOCs with the hardware required to support the cameras. In the end, we'll probably end up with a mix of SLAM cameras, and lidar. Full body tracking is all that's keeping lighthouses relevant. Maybe that goes away with more cameras. :) If you have enough cameras/lidar, you get tracking of all world objects, not just those with sensors attached. 1. https://dl.acm.org/doi/fullHtml/10.1145/3463914.3463921 https://dl.acm.org/doi/fullHtml/10.1145/3463914.3463921 > The results reveal a significantly higher accuracy for the Oculus Quest 2 compared to SteamVR Tracking in the height of a tracked object. Furthermore, the Oculus Quest 2 tracks its position with substantially higher precision than SteamVR Tracking.
