Looks... neat?

That scrolling would be great on a tablet. I put lots of sheet music pdfs on my iPad and hate having to take my hands off the instrument to manually scroll a touchscreen.

I've been looking forward to this since you guys talked about it last week. Very interesting tech.

hmm, i wonder how better I would be at starcraft if this technology was implemented

Does anybody know why this tech is currently so expensive? I mean it works with infra red and uses cameras like many other things in our everyday life. Are the cameras they have to use to detect pupils that high end that it costs thousands of dollars maybe?

The future!

Very cool, this is definitely something that i bet will be part of all electronic devices (phone, laptop, tablet, ect) one day.

So cool.... but for people who use computers constantly, we're pretty damn fast with cursors, and we usually look at wherever the cursor is anyway. I dunno, I used CAD all the time zooming in and out like this, and I can't imagine it being much faster. Though whenever something would go wrong and it didn't zoom where my cursor was, it was so very annoying. Maybe this would remedy that?

That's pretty awesome. Not controlling your PC with your mind, but it looks good enough to be able to pretend to have psychic control over your computer.

Quite simply? There are no real hungry competitors. I work with Tobii products pretty much every day and the long and short of it is, they are the Justin Beiber of the tech industry; meaning they have something very flashy and easy to use, but has a ton of problems on the back end when it comes to robustness. On top of that, there are certain reliability issues associated with these IR eye detection systems, in general, that keep them from being able to mass produce these things. In my experience, with tobii especially, getting the hardware to detect eyes on a multitude of people is near impossible. People over 45, people who wear thick glasses or bifocals, people under the age of 15, certain people's of color, they all have problems calibrating to the system which can provide spotty data and, in this case, really sporadic selections and detection.

TL:DR - due to hardware limitations, all of this stuff is perpetually in alpha, so when people want to buy units, they're essentially getting custom made alpha kits. They (and not necessarily tobii but all eyetracking companies) can't provide consistent reliable data to big names like, say, Leveno, and work out a bigger manufacturing deal, so they're constantly looking for partners to make everything more sound. Personally, Tobii needs to get their act together when it comes to their software. It doesn't help that the lionshare of people using their stuff right now are European universities who never come close to stress testing the software, which causes more focused companies to almost never have their demands met when it comes to modern 2012 needs and wants.

How good is it at re-locating your eyes if you glance off-screen? I wouldn't want to have my head stay in the exact same position for hours on end.

My immediate train of thought :|

I don't really want to do advertisements, but you say in the video, that this tobii gaze tracking is in the multiple thousands of dollars - but at University I work for, there's a group of researchers developing an open source gaze tracker, which is downloadable for free here: http://www.gazegroup.org/ and all you need is a webcam and an infrared light. I can only encourage you to check it out, since what you show in this video looks very similar to what these guys are doing.
