Let the Mindgames Begin

chienr writes "Like Pong, but instead of paddles, you use your brainwaves to control the ball over to the opponent's goal, that's Mindball! This apparatus was previously an experiment under the name Brainball, and is now commercially available - here's another link with video."

    Isn't EGG electrogastrography...having to do with measuring stomach/digestive tract activity?

    Don't they mean the EEG, the electroencephalogram?

  3. Re:Rather steep price by Not_Wiggins · · Score: 4, Informative

    $19k for a simplistic, albeit technically interesting, game seems rather steep.

    Was thinking exactly the same thing.

    Instead of directly reading brainwaves, one could rig up a similar game using those cheap "bio-feedback" devices (you remember... the ones that attach to your finger and generate a tone? The "more relaxed" you are, the "lower" the tone goes).

    Sure, it wouldn't be *exactly* the same, but it would be a similar concept... and for under $50.

  4. Real Multi-Axis Mind Control by spun · · Score: 4, Informative

    Check out these guys. Full multi-axis control, even a brain controlled mouse with clicking. Hell, they even piloted a sailboat with it. I saw it years ago on some science show, and they are still around. Much more advanced than the expensive showpiece in the article.

  6. Veteran of a Thousand Psychic Wars by Anonymous Coward · · Score: 2, Informative

    I've played it. Fun stuff.

    They had a table at the Wired NextFest in SF a few months back.
    It was one of the most entertaining things for me there. (The Z-Printer was
    another cool thing. (Printed 3D models.))

    As they describe, a person per side, each with a headband to read brain activity
    like an EEG. Press a button for game reset and the ball moves to the center
    (magnetic mechanism under the table). I believe the graphs' Y-axes corresponded
    to brain activity *frequency*.

    (Brain wave frequencies for your reference:

    Beta 14-30 Hz Alert Wakefulness
    Alpha 8-13 Hz Relaxed
    Theta 4-7 Hz Drowsiness, Unconsciousness
    Delta .5-3.5 Hz Sleep

    (Brain Wave Frequencies) )

    The ball had each hemisphere a different color so the rolling was more obvious.

    Three graphs: One for each player's brain activity and a combined graph to
    illustrate the difference. The greater the difference, the faster the ball
    motion.

    It's weird. You have two contestants struggling against one another through
    being calm. They sit and stare at the table, or even close their eyes. And
    then the ball on the tabletop moves without visible interaction. It does indeed
    look like some bizarre telekinetic battle. I really liked that.

    People freak out a little bit more as they start to lose. Interestingly,
    children who played had very, very poor control over their frequencies. Their
    graphs were consistently frenetic.

    I lost my first game, figured out roughly how to control my activity in the
    second game (won), and the final game I spent toying with my opponent. I would
    relax my mind and unfocus my thoughts and the ball would start rolling toward
    the goal on his side of the table. Relax, relax... and when the ball was on
    the verge of scoring I started thinking wildly and trying to feel panicked,
    and maybe move my eyes around a lot. The ball would slow, stop, and reverse,
    heading toward my side of the table. It must have looked like an epic battle,
    but I was just fucking with the guy. My gf saw my graph go from smooth and low
    to jerky then back and she figured I was messing around. After a while it
    seemed like maybe it was going on too long for the audience's amusement, so I
    finished him.

    Maybe I'm biased because I won, but I thought it was very fun. I can see this
    being a great parlor game *and* biofeedback tool for practicing meditation.
    Hey, maybe battling against your own previous performances is a good idea.

    Those who find this mind-blowing might want to check out Ender's Game by Orson Scott Card - fantastic SF book (winner of both the awards whose names I can't remember now). At its core is a game not so unlike this (although admittedly a tad more sophisticated)...
