Can't wait until this makes its way to adtech. You can have sites that hold their "premium" content hostage until you allow camera access and proved (via eye tracking) that you looked at their ad.

Boy, I love to see an r/lol reference on HN. Gotta be a lot of crossover, right?

Earlier quoted context omitted.

There’s two parts to that implementation of such a system, and they’re both interesting! The first part is detection of a micro saccade which is already available in research systems I have personally worked on. You can basically crank up the camera frame rate until you’re around the micro saccade range and do some clustering analysis on the positional data to decouple the hardware moving vs the face. The second part…

That's fascinating, but I'm wondering what is the practical value of detecting microsaccades? Aren't they just involuntary twitching?

For the duration of the microsaccade, you're blind. So if something changes onscreen it's much harder to see.

IIRC people have used small orientation changes during microsaccades for redirected walking in VR. You feel like you're walking straight but you're actually curving back on yourself.

Edit: I think that was just detecting full-on saccades but a microsaccade version would be smoother and harder to detect.

There is a short part of this in Black Mirror episode: Fifteen Million Merits.

To earn credits you must look at an ad-video, but when he looks away the video stops and makes a crazy sound so you'll continue to watch the ad...

I wonder. Obviously its technologically possible, but would average user accept it?

It is both possible and being pursued actively. I believe the average user will accept it. The average user has an uncovered camera on the computer and almost everyone has an uncovered camera on the phone. Requiring a cookie banner notification did nothing but make it more annoying to use websites, with less accountability on the site administrator for all the questionable actions they can freely undertake, now with your consent! But it goes far beyond that - there will be cameras embedded in digital billboards/posters you walk past that track your gaze and provide targeted ads based on either facial ID or device ID, the ad effectively learning who you are through your leaky apps or always-on bluetooth.
