Low-Cost EEG Head-Sets Promise Virtual Reality Feedback Loops (thestack.com)

Posted by timothy on from the what's-on-your-mind dept.

An anonymous reader writes: Researchers from the University of Memphis have found that it's possible to use a low-cost EEG device such as the $300 Emotiv Epoc to understand how a user is feeling — opening up the path to genuine psycho-biological feedback in virtual/augmented reality scenarios. The Epoc has been used, in combination with the Razer Hydra, to give users control over VR/AR environments, but integrating emotional feedback into VR environments heralds many new possibilities in the fields of medical research, gaming — and, of course, marketing research.

      Actually it is a very good idea. The best games know when to dial up the action or horror, and when you've had enough action and are getting fatigued, give you a little break. Timing is everything. F.E.A.R. (the original one) had especially good timing with scary moments, as did Halflife 2 with action sequences. Valve put out a paper (PDF) which includes some information on how they were analyzing "emotional intensity" (page 77 of PDF) in Left 4 Dead and having the AI Director adjust the amount of action based on the player's situation and how stressed they may be. The game can't measure player stress directly, so it used information in the game such as player health and whether they were under attack. Usually this results in good decisions and an enjoyable player experience, but the measurement of player stress are indirect so sometimes the AI Director makes the wrong choice.

      Having an AI Director such as the one in L4D hooked up to an EEG could allow for a game that adjusts difficulty / action / horror based on the player's actual emotional state. All other things being equal, it should result in more enjoyable games.

      I have considered combining AR with the Emotiv EEG controller for some years now.

      The EEG input device allows full hands-free operation of the embedded platform (but has several outstanding bugs related to signal noise, and user training). This means google-glass can now be used without having to, for example, touch the eyepiece to take a picture, or start recording video-- Or regions of the AR image can be enhanced/manipulated based on user attention focus.

      A low-cost (300$ is not low cost, unless you live in some hyper inflated local economy. Yes Silicon valley, you are a hyper inflated economy.) synthesis of these could enable all kinds of useful applications, from AR assisted night driving with bright IR LED based headlights and computer processing (does not blind other drivers, gives lots of illumination for the computer to do image capture with, and the resulting presentation requires no physical input method. Not even "pinch to zoom".)

      To take off though, the fully integrated product needs to approach the 100$ price point. That includes hardware and software.

      We aren't there yet.

      (Other, highly lucrative applications: Soldiers with AR targeting. Limited upper body exo-harnesses intended to collect EEG motor-area data and correct body posture accordingly for precision sniping, etc. Hollywood already thought of this shit years ago. Tech is just catching up.)

      Of course porn, people have been saying since at least the 90s that VR will never exist as a commercially viable thing without porn.

      Apparently everything after the wheel and fire wasn't going to succeed without porn.

      I'm surprised hybrid cars even managed a foothold without porn .. actually, wait, I'm sure rule #34 will come into effect, never mind.

      So, maybe what we need to do is get the porn industry involved in all of those "Solve This Major Problem" things ... solve world peace and we'll show you our tits kinda deal. (And, so we don't have it too sexist, for the ladies we'll show you that Channing Tatum guy's backside or something, you can save the world in exchange for tawdry things too, we don't mind.)

    Well, it seems unlikely that it's going to get in through a bunch of EEG *sensors*. And if it can in through the eyes and ears then the EEG probably isn't necessary. In fact, I think quite a few memes might qualify already.

    Yeah, it sounds like the stuff of SciFi movies but if you check the research to date on detecting and identifying emotions via EEG, you'll see that even with big expensive medical grade EEG machines and headsets, they're having trouble identifying something as rudimentary as happy vs. sad. The paper the article is referencing is about detecting whether there is an emotional response or not, not what kind of emotional response. In short, it's some tech company trying to sell useless junk to new-agey types without a sufficiently well-developed bullshit detector. Do they think that gamers fall under that category?
