A Better Thought-Controlled Computer Cursor 34

An anonymous reader writes "Stanford researchers have developed a new algorithm (Abstract only) that significantly improves the control and performance of neural prosthetics — brain-controlled computer interfaces for individuals suffering from spinal cord injury and neurodegenerative disease to aid interaction with computers, drive electronic wheelchairs, and control robotic arms and legs. With this algorithm, monkeys implanted with multielectrode arrays in motor regions of their brain controlled a computer cursor more quickly and accurately than ever before, including navigation around obstacles. Further, the system maintained this high performance across 4 years, demonstrating long-term reliability. These improvements in performance and robustness are crucial for clinically-useful neural prosthetics, and pave the way for success in clinical trails."

  • If the monkey thinks in circles, then the cursor moves in circles, rounds obstacles, and goes fast.


    Does he have a db25 plug on his head?

      It's probably wireless and I'm also guessing the test device was probably a Blue monkey [] over Bluetooth.

        Good idea. It was probably the cats with wires to their heads that inspired PETA.

  • thats nice and all, but is it good enough to play teamfortress 2 online with?

    Emacs cursor control
    Actually we are stoping using mice and starting to use gestures instead
    Not sure if gestures are good for cursor control

  • When you said thought controlled computer I thought you were talking about Nate Silver's brain. But who knows which part thinks and which part is the computer?. Just the cursor. meh!

    Nate Silver jokes:

    Schrodinger's cat experiment is over. Nate Silver can tell if the cat is alive or dead without taking a look.

    When Nate Silver's code throws an exception, he catches it before the debugger does.

    Nate Silver's compiler does not show him error messages. It files an RFD to change the C++ standards to comply wit

    • The famous Einstein quote, "God does not play dice" is incompletely reported. The full quote is: "God does not play dice with Nate Silver".

    i swear i read an article in discover magazine (i know, a magazine, it was that long ago) about some researcher that had hooked up electrodes to a patient and taught them how to control a mouse cursor, and later and electric wheelchair with their mind. it became and autonomic function, just like moving your arm (i hate the term "thought controlled", you dont really "think" about moving, its subconscious function) and it was done using a basic EEG(?). am i imagining this, or does anyone else remember this as well? its quite possible that this is a completely incorrect memory thought, i was a kid at the time and i read a lot of sci-fi, so its very possible my memories of real-sci have mixed with my memories of sci-fi
    • Yes, they've been doing this for a long time now. Only since then they've been trying to improve its responsiveness and accuracy.

    Stephen Hawking is probably jumping up and down for joy now.

    Errr, wait....

      According to the article, he's just not thinking hard enough.

  • They may call it a cursor but this is evil bioengineering where they turn monkeys into mice!
