My eyes and fixation point.
I had to change the plan a bit as the C++ socket.io implementation I was using was taking ages to get working as it's very depreciated. I dusted off a project of mine from March that sends gaze information via OSC, an interesting networking protocol originally used for audio/visual devices. I think I'll create a nodejs server that listens for OSC events and then dispatches them to the browser via socket.io.
The backup plan is to use C# .NET, which I want to avoid at all costs. I just wanna make an interface, all this server stuff is so annoying.
