This release includes support for Roll Data. Also added improved drift handling. Added the ability to rotate 360 degrees in game using Opentrack UDP and added this feature to mouse emulation too. I added Kalman Filter to remove drift from final values from gyro data so you get a very stable picture. Kalman Filter is also used for mouse emulation. I also added opentrack drift fight buttons to allow users to fine-tune their Xreal Air glasses needs. I tested this release on many games to give you guys the best experience possible. You can now play your games like never before with Nreal Air. SteamVR works too. It's very easy to make this all work. Just download opentrack and run it. change the input to UDP and take a note of the port which by default 4242. Then on PhoenixHeadTracker just use the IP 127.0.0.1 and port 4242. Click on 'Start Opentrack UDP'.
You will need Opentrack
