the sensor fusion is now pretty much perfect! the PS VR2 controllers are temperamental because it sometimes gets bad input (bad in -> bad out), but the Oculus Rift headset, which has generally good data, has pretty much no issues to my eyes #monado #foss #linux

after another couple weeks of work, we have sensor fusion in Monado! it's still missing some robustness related features and is a bit fragile/jittery at the moment, but works quite well as-is www.youtube.com/watch?v=2ZPz...

lots to do after this, mainly online sensor fusion so that tracking jitters and latency is smoothed out and multiple cameras per frame contribute to tracking accuracy but things are working way better now! all baby steps towards making Monado's constellation tracking user-ready

Beyley Cardellio @beyleyisnot.moe · 05/08/2026

after 2 weeks of work, we have room setup in Monado! this is a super early version (the LEDs on the back of the strap cause tracking issues, since fixed after this video), but it's able to use offline sensor fusion to automatically compute the camera positions!

there were quite a few bugs and issues plaguing the code which produced the really poor tracking in the past, some straight up mistakes, some assumptions that worked for CV1, but not for PS VR2 controllers, but fixing all that up things are working really well

Beyley Cardellio @beyleyisnot.moe · 04/07/2026

after a lot of work the past few weeks, Oculus Rift + PS VR2 controllers works *so* much better now! tracking is stable outside of some fringe cases with few LEDs along with the ever-lasting occlusion problems you get with a single camera

been hacking on this in the background tracking is quite a bit better, and most importantly LED sync is now very reliable and we're able to get the LED blink times down to the minimum possible for max battery life still *definitely* not end-user ready, but we're making steady progress

open MR here: gitlab.freedesktop.org/monado/monad... all of this work is *extremely* early, as you can probably tell by how very jittery the tracking currently is, pending many improvements to the constellation tracker, and also still missing sensor fusion

finally sharing what i've been working on! with help from the PSVR2Toolkit devs figuring out LED sync, we have very early constellation tracking of PSVR2 sense controllers on Oculus Rift in Monado! in the future this should also expand support to other IR-camera headsets like PS VR2 or Rift S

nyeinyh! been awhile since i last showed anything i was working on, even though i've been busy with VR stuff, but here's a teaser of my recent work on Monado's Rift driver! (bonus ducks to anyone who can recognize the two suspicious extra devices from their LED patterns alone)

An image from the Oculus Rift CV1 camera showing the bright LED flash patterns of five distinct devices, with two of the devices being unidentified.

small update, no video this time 🐾 after a *lot* of effort the past couple days, i *finally* have Wii Motion Plus data sent to Monado! turns out the kernel kept turning it off automatically, so i wrote a new L2CAP HID implementation for Monado, bypassing the kernel entirely
