 ## System overview
 
 We track gaze by modelling the iris as a 2D ellipse in an image, and _back-projecting_ this to a 3D circle, getting the real-world position and orientation of the iris. We take the normal vector of this to be the gaze direction.

 1. Open the solution file `EyeTab.sln` in Visual Studio. I used VS2012.
 2. Add dependencies to Visual Studio' _Additional include directories_ field, _Additional library directories_ field, and as _Additional input_ in the linker.
 3. Ensure the required `.dll`s can be found on your `PATH` or in Visual Studio's debugging environment.
+4. Build and run the solution.
