Sorry, that was obviously too fast.
I discovered the Interop.cs and got aware, that this is obviously “simply” using a C library in a C# project. So nothing StreamEngine specific, but a fundamental programming concept i’m not familiar with yet.
I’ll follow that route and dig there deeper…
If it is possible and sensible to roughly sketch the fundamental approach of subscribing to a gaze data stream using the C library, that would definitely help, nevertheless 😉
