This is a little off topic, but I can't stand sites that make me click 'next' 10 times just to read their article.. It instinctively makes me not want to read it.
Related to your off-topic comment: read the comment on the article site. :)
Edit: Because it will probably get taken down, it says "Another great startup you should look out for is SlideshowAssassins, it goes and kills authors and webmasters of crappy sites that whore out for ad clicks their articles by spreading them across stupid, pointless, annoying slideshows."
Quite a few of these were check-in/advert type applications. I can't make myself even try these things, like foursquare facebook places, etc. I just don't like the idea. Anyone I want to know where I am, knows where I am. Adding lots of ways to sell me stuff after I check-in, or just straight up following me around tracking live for marketing purposes, solidifies my resolve to not use these things.
I can't say I would absolutely need any of these things, but their uses seem like they would work well in special cases, like some with some big company or something. I suppose there is a market for these things, but overall I'm not sure how necessary they really are...I think I may just not be reading about them detailed enough, nor do I want to cut down on the hard work of these developers, but how necessary is the next step in social TV, or something..
Nope, our main advantage is that we can be run in a user's own home. We use ordinary webcams, so if you have a laptop or webcam attached to a desktop we can track you.
From GazeHawk.com "GazeHawk provides webcam eye tracking services. Our patent-pending technology allows us to runeye tracking studies in users own homes at a fraction of the cost of traditional custom hardware."
