There are lots of UI interactions in AR/VR based on gaze. It’s a top-tier paradigm in Hololens, for example. Personally I find it annoying; I want to concentrate on the content not some button or action zone. Part of the problem is that our eyes don’t work the way we like to imagine, they skip around and look at lots of different things and our brains then synthesise a gestalt view. There is a tendency for our eyes to be pointing more at the things that interest us but not _specifically_, eg at the keyboard, not at a key.
I think it is possible to use gaze as a secondary input in a UI and would love to hear examples of where it has been done because I haven’t seen any yet.
