Hi,
first of all (since I'm new here), congratulations to the eyetribe team on making eye tracking more accessible and affordable! Keep up the great work!
I have a question: is there a chance it will possible to get some head tracking variables in some future versions of API? You probably need to measure head movements in order to compeasate and I'm interested in accessing the raw variables (like distance and angle of the head).
This could open some new use cases for your tracker (it's enough to search for "head tracking" in youtube too see what I mean). I will post here why I'm intersted (it's a bit more specific):
