I just saw something that I thought those readers of the young adult novel Feed by M.T. Anderson might be interested in. (Our LOL high school group read and discussed feed last spring.)
I was just reading through a library journal and came across reference to this article "Direct Brain-to-Game Interface Worries Scientists" from Wired magazine (link below). It talks about how the technology will use brain activity--essentially thought--as the video game controller...which is really close to how the implanted "feed" in the futuristic sci fi novel used thought to automatically innundate the thinker with "targeted" information.
