Or so the people at Emotiv would have us believe. Being the kind of guy who absolutely cannot wait for the day when, as Jonathan Coulton sings, "the things that make me weak and strange get engineered away," I pre-orded Emotiv's thought-controlled EPOC mind-computer interface device as soon as I thought I had $299 to spare. As it turned out, being the first on your block with the new toy comes with a real risk: you might end up buying a frustrating experimental prototype for the cost of five new video games.
There's no denying the unique thrill of watching something move on my computer screen just because I thought about it. I giggled the first few times it happened. My friends who were over when I un-boxed and hooked up my EPOC on day one kept saying stuff like, "Wow, that's so freaking weird. And cool." It really does feel a little bit like magic, although less so because you're wearing a web of 16 saline-soaked sensors clamped down onto your skull by a plastic headpiece that connects wirelessly to your PC via a USB dongle. So really you feel like a cyborg, which is just as good as magic in my book.
The EPOC is a delicate feeling device. Before slipping it onto your noggin, you've got to individually dampen the 16 sensor pads in their case (but not too wet, the instructions warn). Then you have to slot them into the 16 holes in the headpiece and try to slide that into place without any of them falling out. I can now do this pretty well, but the first half-dozen or so attempts regularly sent five or six of the sensor pads cascading onto my shoulders and rolling away around the room. When you're done with your mind controlling you have to carefully remove the EPOC to avoid a similar mess and then slot the 16 sensors back into their storage case. All said, that's five to 10 minutes of set-up and clean up every time you use it, including time spent adjusting the fit to make sure all the sensors are where they're supposed to be and reading your mind five-by-five. It is definitely not a pick up and play controller. Then you have to train it. The EPOC has three ways of sensing your intent. It can monitor facial expressions (although not with the camera, but with the brain function sensors), allowing you to map winks and smiles to specific keyboard commands. It also has a gyroscope in the headpiece so you can move the mouse cursor by moving your head. But the star of the show is the brain sensing, which you train with the help of a 3D orange box floating in virtual space on your monitor. The EPOC software allows this cube to move up, down, forward, back, left, and right as well as spinning in different directions. You have to train the device in each of these motions, choosing a thought (Up! Up! Up!) and visualizing the cube moving over and over again while the EPOC studies your brain activity. The instructions suggest you might want to make a hand motion as well, but it didn't seem to make much difference in my training regimen. You can also have the cube animate the action you're trying to train, which helps you visualize what it is you're thinking so hard about.
When that cube slides to the right or recedes into the background with nothing more than a flashing thought, it's amazing. When you stare at your computer and try and think the same thought over and over again and nothing happens, it's as frustrating as can be. We develop skills in part by learning from our mistakes. The core problem with training and using the EPOC is that it's nearly impossible to know what you're doing wrong when all you're doing is thinking. I mean, I think I'm thinking what I'm supposed to think, but nothing happens. I'll spam out "Right" over and over again with my mind and the cube just sits there.
First there's Emotipong, which is just regular old pong, but with your mind. |
Emotiv offers software called The Cortex Arcade for free from its web site. At launch it included three simple games meant to be played with your EPOC. First there's Emotipong, which is just regular old Pong, but with your mind. Move the white bar up and down to deflect the white square back at the other white bar. There's even a slow mode for us newbie telepaths. The Arcade has a display for what it thinks you're thinking, and while I thought long and hard about that bar moving down to intercept that square, it thought I thought "Left," which isn't a direction that paddle moves. Playing a slow motion game of Pong that's harder and more frustrating than Ninja Gaiden on its toughest setting is not a happy experience. Especially when, for the briefest of flashes, you see that an errant thought can send the white line moving up and down at a good speed.
Cerebral Constructor is a fancy name for mind-controlled Tetris, and I had no better luck controlling those falling geometric chunks with any reliability. Finally there's a Jedi Mind Trainer game, which I can't imagine Lucasfilm approved in any way. Here Yoda wants you to levitate a cutout of an X-Wing as long as you can, which for me was never more than a few short stuttering hops.
With all that promise, all those allusions to nerd icons like the Jedi, it's hard not to feel a little taken advantage of. |
You can map your EPOC thought-commands to keyboard inputs, so theoretically, coupled with the head-movement cursor control to replace your mouse, this could be a controller you'd play other PC games with it. I cannot imagine how that would work in even the simplest game, given that Pong is arguably the simplest game out there. Likewise, I don't see anyone using it to send instant messages, compose e-mails or browse through their photo galleries (Emotiv does offer a gallery interface application). Since I couldn't get it to work with the applications designed to use it, I did not try to control a game like Torchlight or Plants vs. Zombies with my mind.
The EPOC is not a mass market device for people looking for a turnkey telekinesis solution. It's an expensive toy for people to experiment with, or a cheap device for scientists to do research with. It's fun to show off to your friends but probably not something anyone will want to play with for very long. The signs were there from the beginning that the EPOC might not live up to its hype, but with full page ads in places like the pro-transhumanist magazine H+ and promises of sci-fi technology in the here and now, Emotiv clearly sees geeky gadget enthusiasts like me as its target audience. With all that promise, all those allusions to nerd icons like the Jedi, it's hard not to feel a little taken advantage of. Seldom has the early adopter tax (one I've paid often) felt more onerous. But because I've already spent all that money, I'm not going to give up on Emotiv or my brain. I'll stick with it some more, and keep training my brain, probably with the same tenacity I used my Wii Fit.
