Disclaimer, I am the primary engineer of a commercial eye tracking system.<p>Tools like these popup every now and then are a nice tool for rough estimation of gaze. Fixation tracking is a large complicated issue that usually requires some sort of calibration to get more precise results. By sidestepping the calibration problem, much higher subject compliance can be achieved since you don't have a grad student barking confusing order at you. The downside to this is the noise you see in the tracking results. For those interested a product that produces similar results is
pupil labs ambient gaze tracking "Core" research headset[0].

Had a blast at LauzHack '16 using this library to make a Chrome extension enabling "no-hands scrolling"[1]. Sadly, reading web articles while eating with both hands is still a dream. We managed to get okay-ish results on a MacBook Pro in perfect lighting from time to time, but nothing consistent. In variable lighting and on lower-end laptops we found it impossible.<p>I wonder if it would be possible with a better webcam and good, consistent lighting.<p>[1] <a href="https://github.com/jarlg/lookmanohands" rel="nofollow">https://github.com/jarlg/lookmanohands</a>
In the brown undergraduate computer vision course one of the homework’s (or final project; my memory is a little hazy) was to improve the tracking of webgazer. People were pretty successful from what I remember. As an undergrad I didn’t think much of it but as a grad student I would be slightly mortified if undergraduates were improving on my current research for homework.
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.
I had an idea for an evil-eye game, in the style of Happy Tree Friends or so. That is: a lot of cute creatures around, and nothing happens (they may giggle, jump or blink occasionally) until you look at them. If you do...

It's using WebGazer as it's core - but with many improvements done by us.<p>BTW I'm RealEye co-founder so AMA :)
Sadly my eyes are too small to actually track the pupils. I remember when I got my ID, the lady taking the picture said "Sir, please open your eyes". I looked at her and asked "They are open... you don't see that?" She laughed and asked if I had been smoking. :/
Whoa. I have a strange mix of reactions to this. It's impressive, and interesting, and worthwhile, slightly creepy, and potentially hugely useful for a11y, democratizing cutting-edge HCI, AR, gaming, etc etc. Surprised it's not getting more attention!
This seems really cool but it doesn't seem to let me choose which webcam to use- it seems to default to a virtual device I use for streaming that isn't set up right now so I can't really try it out.
The "move the ball around with your eyes" demo doesn't work at all for me in Safari on a MacBook. I can only move the ball with the mouse. The other demo works okay, but very low accuracy (like 50%). Firefox on the same computer is unusably slow, generates a new "data point" (the visible dot) only every few seconds. Accuracy was about 10%.
The listed use cases here struck me as odd, I can't imagine why I or anyone wanting to read a news article would allow the site access to my webcam. Nor do I think most users would turn on their cameras to help with any given sites analytics.<p>So aside from games, what is the actual use case here ?
I tried my best on the calibration demo page in Safari and consistently get a 0% accuracy result. It calibrates sort of ok in Firefox. I guess this is heavily browser dependent? But why?
I tried using this one time but unfortunately found it didn't work when I wore my reading glasses. The screen reflection off my glasses just whites out both eyes.
