Has anyone here tried this: https://tobiigaming.com/eye-tracker-4c/ and if so, what are your thoughts on it? I'm not so keen on the VR stuff (yet) and use a TrackIR from time to time, but the eye tracking system seems a bit smarter and from what i understand it doesn't require any "head-gear" at all. The max recommended screen size however is 27" for 16:9 and 30" for 21:9 aspect ratio. I'm using a 40" screen at 16:9 so this might not be possible for me at all, but still interested in hearing your opinions and also if you use a larger screen size than recommended. Thanks!
