It has been a while that I tried Star Citizen. With the new Neuralnet Tracker plugin (AI haha) for OpenTrack we get head tracking without annoying IR LEDs or reflecting stripes just by reading the webcam video feed. This is apparently fast enough to try head tracking without a dedicated head tracker nowadays. And all that on a Linux PC. Took some fiddling but the concept still works. What a time to be alive.

    Nice. How’s the input lag compared to IR? Can’t really tell from your video if there is a lot of delay between head movement and camera movement in SC.

      Can’t tell for sure either. It Lag feels slightly higher but perfectly fine for trying some head tracking without investing in additional hardware. This depends a lot on the processing power, of course. Cam doesn’t matter that much. It seems to read with only ~540 px width or something and any webcam of the last decade should manage ~50 fps with that 🤔

      I’m also uncertain what the current penalty is for running this on Wayland via gamescope, which is really bringing my rig to it’s limits.

    Hey, lots of great pointers to nice tools in here! Thanks, and well done for making this work in SC :-)

    what needs to be done to get around error protocol dylib load failure ?

    edit, ah i guess i should set an output like UDP huh

    This sounds a lot like FaceTrackNoIR but I haven’t messed with that since I got a VR headset. Good to see stuff like this still getting development

      It does have some protocol overlaps especially for UDP. Not that it’s very complicated but it helped me when I implemented this in FreeSpace Open to get head tracking working on Linux PC too 🤓
