In my little series of Cybepunk tech allready available today: The brain-computer interface. The very core of every cyberpunk book – the ability to plug yourself into the matrix.
Well, today you can use it to surf Second Life. Second life is NOT the virtual reality I imagined reading Neuromancer, but some like it there:
All a user has to do to control his/her avatar is imagine performing various movements. The activity monitored by the headpiece is read and plotted by an electroencephalogram, which relays it to a computer running a brain wave analysis algorithm that interprets the imagined movements. A keyboard emulator then translates the data into signals which can be used to control the movements of the user’s on-screen avatar in real-time.
As usual, boing-boing has the details (including a link to a video)
