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.

Why? Someone smarter will always follow

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.

"Wanna play a game? Just move the ball to the hole with your eyes. Oh and we need access to your camera."

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. So aside from games, what is the actual use case here ?

I'm starting to develop RSI in my wrists and hands, and have been looking at eye tracking systems as a potential way to help reduce the amount of clicking that I need to do.

I was thinking maybe I could put webgazer.js into a chrome extension and use it to navigate through pages for me, but I don't think it has a click mechanism.

fwiw - I'm a huge vimium extension user as keyboarding is less of a strain than mouse movement.

Disclaimer, I am the primary engineer of a commercial eye tracking system. 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 co…

It depends on your application. If you're trying to replace your mouse with gaze, then yes you need careful calibration. I have worked on some purpose-built gaze interactive experiences and coarse accuracy without calibration can be enough to do something useful.

Not even just smarter; we all stand on the shoulders of giants, and every year the barrier to entry falls that much more.

Have you looked at https://eviacam.crea-si.com/ ? Supports Windows, GNU/Linux, and Android, works globally, and runs separately from the browser. (Technically not eye tracking, but close enough)

I would absolutely love to see something like this combined with a live video filter to make actual eye contact during video chat possible.

Great question. There's a use for usability testing, where paid participants currently sit at an application in a lab to do eye tracking. So there can be a similar version online for if let's say, Bloomberg is testing a new version of their online terminal. Multiple large companies exist that solely develop eye trackers, so there's quite a market for this. Plus it does not have to be monetary compensation. I could im…

I suppose that might be an option, but in my experience people are highly unlikely to grant a site permission to their camera if they aren't using it as part of a conference call.

But I do agree if you have some A/B testing, that the users are doing it as a part of a study, it might be usable.
