Easy Head tracking . . .seriously Easy

What’s the most reliable input method in Opentrack?

I use an infrared LED clip attached to my headphones with a typical modified Playstation 3 Eye camera and tracking is rock-solid, never, ever glitches.

The reason I don’t use the Aruco method is I prefer piloting in a dark room.

Or, did you mean input as in setting? Under Opentrack “Protocol” I select Freetrack 2.0 Enhanced
