Tobii 4C eye tracker
I'm on a limited budget at my university, so I'm looking for an affordable eye tracker. The Tobii 4C caught my attention. I'm pretty new to do this and still figuring out how everything works. Reading through the PyGaze manual, it seems that the Tobii 4C is supported, but I see also things about upgrading the license key for the Pro SDK of Tobii. Do I need this upgrade of the SDK in order to make it work with PyGaze? Or can I just start using the eye tracker with the normal license that comes with it.
