Hi @jonico, If you are referring to getting started using the EyeX for Gaming, then you need to have installed the Tobii Infinite Screen extension which will interface with a number of existing Gaming titles available for your platform. Please load the application. You can download all the necessary software @ https://gaming.tobii.com/getstarted/
If however, you wanted to start developing with the EyeX SDK then perhaps one of our many tutorials available online will help you get up and running @ http://developer.tobii.com/category/tutorials/
