Connect Your Brain to a Computer. Seriously!

The setting: your home.  The time: 7:30pm, in the not-too-distant future.

Your room is dim and cool, and the hum of a city evening drifts through the open windows.  Your computer screen’s high-frequency flicker casts shadows all around.  The metal object in your hand resembles an old-school headphone jack.  It’s small and surprisingly heavy.  You heft it once, twice, admiring its simplicity and craftsmanship.  In the time it takes to draw a breath, you plunge it into a socket in the back of your neck.

Click.

The world blurs into dizzy static for a tenth of a second, and then it’s back.  But it’s not just back, it’s somehow more.  Everything around you is pregnant with invisible layers of meaning.  All the world is tied together, and you’re plugged into it like a spider in the middle of a 3-dimensional web.  In seconds, you start brewing a pot of coffee, tap into a virtual-reality newsfeed, pipe some music into your auditory cortex, and fire up your latest project so you can get to work.  All without moving a muscle.

Is the future awesome, or what?

Interface

The paragraphs above may be fictional, but the rest of this post is not.  You see, I’m going to discuss the device in the story, which is known to future-geeks as a BCI: a brain-computer interface.  You can find them in The Matrix and a million other sci-fi movies and books, where characters jack their brains directly into computers (or machines, etc).  The thing is, if you thought that BCIs were purely fictional, you were wrong!  They’re rudimentary, but they’re here, and they’re only going to get better.

As exhibit A, I present you with BrainGate, a tech company that helped a paralyzed man control a mouse cursor through a wire in his brain.  Awesome, no?  Exhibit B is this device from the University of Plymouth that lets paralyzed people play the piano.  There’s even Autonomos Labs, who made a car you can control with your mind.  Check out the YouTube video below, it’s pretty nuts.

For those of you who still aren’t convinced, the ultimate acid test for any technology is whether it can be adapted into a mass-marketed toy.  Pick up the Milton Bradley “Force Trainer,” and try out a rudimentary BCI for yourself!

Input

Okay, so we can read brain waves and use them to drive cars, play music, and live out our Jedi dreams.  But what about the other direction – can our brains receive digital input?

I’ve yet to find a human example, but one group has done this with monkeys.  The animals could move a virtual arm while actually feeling what they were “touching” with it.  Imagine telepathically controlling the Mars Rover… and feeling the Martian sand between your toes!

Obviously, these examples aren’t quite as advanced as in the little scene I opened with.  I admit the technology is still in its infancy as of 2012.  But here’s the key lesson:

It is possible in principle to lower or eliminate the barrier between minds and computers.

Everything after that is refinement.  Like those who closely follow the singularity, I predict a day where interfacing your consciousness with a machine or computer will be an everyday event.  And like them, I predict that the consequences of this will be myriad and confounding.

Implication

So, if you can swallow the “how”, you inevitably get to the more important question, which of course is “why?”  As in, is it really a good idea for BCIs to grow more advanced?  If they become widespread, what could we use them for?  What might that mean for us as individuals, or as a society?

I’ve rambled on more than enough for one post, so I’m afraid the big questions will have to stew for another week.  But stay tuned, because next Wednesday I’m offering my own take on the Top 5 Reasons to Plug Your Brain Into a Computer. [edit: link added]  Spoiler alert!  I’m going to wander off into some highly speculative yet very awesome places.  Until then, talk amongst yourselves, and please feel free to kick off the conversation using the comment box below.  Is this development awesome?  Terrifying?  Completely impossible?  You tell me.

  1. I can most definitely see technology progressing to this point. I personally believe AI and all that it implies is the next phase of human (machine?) evolution of any significance…assuming we don’t destroy ourselves first. Excellent and thought-provoking post. Look forward to next weeks’ entry!

    • Well, that’s certainly true – we do have to keep our civilization around long enough, or this is all moot! Thanks so much for reading, and for the kind words.

  2. Our future is awesome, and a little scary. I often wonder where technology is going to take us in the future, and at the speed it is growing, it won’t be that much further off. People are already being replaced by mechinized wonders every day, and we have gadgets for doing so many of our menial chores. Even as I write this there are probably dozens of new ideas churning in the brains of inventors around the world. Man will soon have no need for arms or legs, he will just be one big blob, and he won’t even need much brain, because the machines will even do his thinking.

    • While I’m excited by the potential of this kind of technology (obviously), I do share your concerns about the effect on society. It’ll be very important to think carefully about these developments, and engage with the weighty issues. We must use technology to create the society we want, since a civilization full of brainless blobs is of no good to anyone.

      Thanks so much for sharing your thoughts, I’m grateful for your perspective.

  3. think about this if we get to the point when we can connect to a computer with our brains and go into a video game you could have back ground programs running that keep your body from turning into a blob.that move you’er body to do stuff around your house. if the monkeys really did feel what the arm felt that means we would be able to go into a game and work out and our body’s would be able to work out all by us being in that game. but also when we get to that point with computers i wonder if we could store our hole being on the computer and live there in the computer with out ever dieing and not needing a body all together

    • Good question! Also a good plot for a near-future sci fi novel. For now, though, your brain doesn’t actually run software the way a computer does, so you’re (probably) fine.

  4. It was really intriguing. I`m on the posters side with this.

    For the scepticals: In the beginning it will be amazing and terrifying, then we get used to it. Being blobs…I don`t think so. From a point bodies will be like clothes. Genders as styles. With high end nano-and biotechnology you can be who or whatever you want to be.

    You may ware the most trendy one but people interested more about your face in the end (which in that case is your personality).

    It will be another step to the recognizing of the importance of the soul.

    But it will take time, that`s for sure. It will be threatening for the old generations and it will cause a lot of controversy, but at the same time it will be marvelous, and I can`t wait to see.
