tbh I'm not certain if they use visible light for the tracking or not, it tracks in surprisingly dark conditions

Have PSVR2 controllers mostly working in ALVR's visionOS client, just need to finish polishing and fixing some crashes

Also mostly passes the Beat Saber Expert+ litmus test, but has trouble on the edges of the FoV. The controllers update positions at 30Hz but have IMU-based prediction to bring it up to 90Hz.

For reference Lighthouse 1 is 50-60Hz per lighthouse, 100-120Hz if you're in both fields of view. Hard to find good sources on this tbh My napkin math on the IMU is that it can prob send velocities (not raw IMU) back to the headset at maybe 120-200Hz, idk how Sony handles it tbh

Actually yeah I remember, the Lighthouse 1 thing checks out I think, the magic of Lighthouse 2 was that the lasers modulated their identification in the beam so that they don't have to sync with each other at all for the most part.

also I got jumpscared by the dark-only ghost hands they added in visionOS 26, they're nice but I needed some warning lmao

targeting the prediction at roundtrip latency looks pretty good tbh, a little bit of jitters but way less overshoot due to the IMU

whoa check this dnb track out

The test for LED tracking I do is using a 240Hz mobile phone camera. For some reason, in my initial tests the controllers didn't show up. I redid the tests today, and they indicate the AVP is indeed using the IR LEDs (or at least turns them on).

Is there a reason you arent using PSVR2 models? They do exist in SteamVR. Just curious.

if it uses imu-based prediction, why it's still looks so lagging behind even passthrough video?
