Toyota Demonstrates Brain Control of Wheelchair

An anonymous reader tips us that researchers at Toyota have developed a brain-machine interface system that allows for control of a wheelchair using thought. The system processes brain thought patterns (such as the thought of moving one's left foot) and can turn them into left, right, and forward movements of the wheelchair with a delay as short as one-eighth of a second. That's a big improvement over existing systems, which can take as long as several seconds to analyze and react to the user's thoughts. "The system has an emergency stop that can be activated by the user puffing his cheeks. The BMI adjusts itself over time to the characteristics of each driver's brainwaves. If a person dedicates three hours a day to using the system, the BMI can reach 95% accuracy in a week, researchers said."

Just before you actually move something, your brain begins to activate the motor control centers, and shortly after that it actually send the signal to the rest of the body.

      Okay, I'll say this again, because it doesn't seem to have filtered through to the general population yet. Until the singularity, the human brain will be able to learn more easily than a computer. Please stop trying to teach computers the thought patterns for specific movements, and just provide a neural interface for the brain to work with. The brain will be able to figure out what signals it needs to fire to get the wheelchair moving (or whatever) soon enough.

      FWIW, my own idea of how to do this would be to put a few small electrodes into a person's lower arm, far away from the brain (and have a sensitive meter to detect nerve firings). Once the brain figures out what nerves are important for this interface, you then use that interface to deliver signals to operate other equipment.

      I know in theory this sounds good but has it ever been demonstrated to work? Can adults recruit new brain areas like this?

      Turns out, yes. With the right biofeedback, the brain remains plastic throughout adulthood. Otherwise, all of the stroke and TBI rehab I've done my whole career wouldn't have worked. I've seen it functionally, and more recently, they've seen new synaptic growth in the lab.
      I don't think anyone will be developing whole new brain areas, but the existing motor cortex can repurpose itself.

Protip: They already hit stuff hard ALL THE *BEEP*ING TIME! Doors and doorways are usually steel reinforced in many institutions, and homes and furniture is frequently worn and battered. Many of the users have scars and bruises on extremities from colliding with objects around them.

    There is a reason the good wheelchair manufacturers build their power chairs like the proverbial tank. Many chairs weigh upwards of 300lbs. If you cannot navigate it, you can at least push it out of the way. Protip II: The power chair in the video is a feeble little thing only intended for light indoor use. It won't have the power to drive through the woods.
