I’m facing the same issue. In my case, I don’t think it’s the Global Interactor. To keep it simple, I have an application with many gaze aware buttons and controls. I want to allow the user to look at a section of the screen and have it pop up a settings panel. I also need a virtual window over the main part of the screen to help manage this functionality.
I am able to it all except for the problem that once I create the virtual window that covers the main part of the application, it blocks any other control from registering gaze. I tried setting the nonOccluding property to true and it doesn’t seem to make any difference.
