With the recent announcement that VisionOS 27 would support custom actively tracked tools, via arrays of embedded LEDs, I would just like to confirm if the demo given in this video here: https://developer.apple.com/videos/play/wwdc2026/283/ at minute 1:00 is indeed an actively tracked tool, or if it is passive IR. if it's passive IR (reflectance), are there any examples of how this could be achieved, i.e. can we access the onboard IR cameras directly?
