Watch this very cool video on text 2.0 and how devices could soon change reading. Great video.
There is also a great companion article in Wired Magazine on eye-tracking tablets and Text 2.0. It admits that Text 2.0 technology is still in its infancy, but there are some really cool applications here. Reminds me of the Minority Report movie in several ways. Of course what happens to privacy? Unintendend consequences of what seems like a good idea at the time, perhaps. Good article to read, though.
