Great that you managed to fix the transform problem.

Regarding gaze coordinates in EyeX SDK, you need to set up a so-called Global Interactor to get this kind of data stream that is not tied to any specific region on the screen. In the MinimalGazeDataStream project in MonoSamples.sln this is exemplified. When using this data in Unity, make sure to use the right coordinate system. As suggested in the Developer’s Guide, the ScreenHelpers class in the Unity sample has some useful code for this.

Good luck with your project! We look forward to see how it goes.

EDIT (by Jenny@Tobii 13 Mar 2014): Since Unity SDK 0.14 there is a streaming gaze data sample included in the Unity sample code.
