Brain Controlled Computing a Reality

pchernyakov writes "Cyberkinetics Neurotechnology Systems told attendees at the American Academy of Physical Medicine and Rehabilitation annual conference that a 25-year-old quadriplegic with wires run from 100 tiny sensors implanted in his brain and out to a computer can use his thoughts to control a computer well enough to operate a TV, open e-mail and play Pong with 70% accuracy."

  1. But how many degrees of freedom? by StateOfTheUnion · · Score: 5, Insightful
    can use his thoughts to control a computer well enough to operate a TV, open e-mail and play Pong with 70% accuracy

    The quote really sounds impressive the way they wrote it, but it seems like the patient is using only three degrees of freedom in their control.

    Use the mind to make the paddle go up . . . use the mind to make the paddle go down . . .

    Use the mind to make the channel go up . . . Use the mind to make the channel go down. Use the mind to switch to volume and repeat . . .

    Use the mind to select next email . . . Use the mind to open the email . . . Use the mind to close the email.

    I count three degrees of freedom . . . This is no different than the guy that was wired up to use his mind to scroll through and select letters to write emails. It sounds good when one says he can play pong, check email and and control a TV, but the truth is that I think that using the mind to control with three degrees of freedom has been done before. This just sounds better because they framed the control in terms of some common tasks.
