Brain-controlled computers

Nature is reporting on their news pages about an electrode-array-bearing cap that a person can wear, which allows them to navigate a virtual environment by visualising walking. Although it takes practice to get used to the system, the breakthrough here is that you don't need to have the electrodes implanted. Just having them held onto your head is good enough. Meanwhile, another group has been using trans-cranial magnetic stimulation to produce an artificial feeling of motion. So that's the start of neural input and output. Maybe I really will live to see cyberpunk technology come true. That would be cool.

Didn't Arthur C Clarke 'predict' this in his 3001 the Final Odyssey with a name called the Braincap ? It helped get Poole up to date after a few hundred years floating in space.
