How To Index and Search a Video By Emotion

Posted by timothy on from the black-beauty-special dept.

robotsrule writes "Here's a a demonstration video of EmoRate, a software program that uses the Emotiv 14-electrode EEG headset to record your emotions via your facial expressions. In the video you'll see EmoRate record my emotions while I watch a YouTube video, then index that video by emotion, and then navigate that video by simply by remembering a feeling. The web page for EmoRate explains how I used Emotiv's SDK to build the software program, and how I trained the system by watching emotionally evocative videos on YouTube while wearing the headset."

  2. Too bad the emotiv SDK costs $10,000 by BitHive · · Score: 2, Informative

    If you want the raw EEG data, you have to buy emotiv's $10,000 SDK. I'll stick with my Neurosky headset for now.

      Neither has a Linux port for the SDK (wink - wonder why this is posted on /. then?)
      Seriously, anyone with some references on similar devices that have Linux support?

      Nonsense!

      The version to access EEG data is $750. They have a $500 developer version and a $299 consumer version - I don't even think they have a $10K product! As for Neurosky, do you mean that toy where you move the pong ball up and down? Sorry, genuinely interested since I hadn't thought they had done much beyond that.

      Still completely fucking retarded. I was really excited about this product before it came out. Was a part of the forums. The they decided they would charge HEAVILY for the SDK to regular users. Who is their audience? People that want to toy with the thing. That is their ONLY audience until there are several thousand apps for the thing and when it is integrated into a bunch of games like the star wars mmo. And that will only happen if you have lots of developers. Which emotive is shitting on.

      They likely made 20-50 grand selling the dev kits. Where-as the starwars mmo having mind control in it would sell at least 1,000 headsets likely way way more. They would have to try to not sell an additional 500-1000 headsets if they opened the SDK.

      Explaining this obvious failure of business on the forums got me tossed then my post deleted. And now the old forums are gone. (When I explained it back then I was much more encouraging).

      Seriously, this thing was super hyped at release but if you google them or look their crap up on youtube they almost completely died within weeks of release. The forum has 2-3 active devs.

      So sad to see such a cool toy ruined by such a stupid stupid obvious business decision. :( That and proving that Balmer is smarter than you has to be embarrassing. DEVELOPERS!

  3. Re:I assume you wouldn't always respond the same w by Kitkoan · · Score: 2, Interesting

    It would be interesting to run this a few times... not sequentially, but maybe once every few months to give yourself time to reset (for the lack of a better word), and rewatch whatever it was you recorded with this device and then diff the results to see if their was a drift, and in what area's. I have to assume you wouldn't always respond the same way, and the results could be highly interesting, perhaps even moreso to the field of psychiatry in allowing a more exact gauging of the effectiveness of whatever drug they are administering to a patient.

    I doubt you'd get nearly the same reactions. Things like boredom (reruns don't always get everyones attention) and (since these are static videos) predictability can and will cause detachment of your emotions and their intensity to what your watching. Think of things like horror movies, sure they can make you feel fear greatly during the first watch, but rarely can cause that much fear during the second viewing, let alone the third, forth, ect...

      Sure, here is the download link for their previous movie, Big Buck Bunny where you can download the movie in multiple formats and video sizes, and at the bottom is the entire studio back up (over 200 gig) where you can download every part of the movie made and used.

  5. Interesting, but... by flimflammer · · Score: 2, Insightful

    I can't say I see the benefit to this sort of system. My facial expression rarely changes throughout movies, unless I laugh over something funny or flinch due to a movie trying to scare me with a loud noise. I'm hardly alone; I showed the video to a few people and they had similar concerns.

    I can't see myself giving off a heartwarming smile when I see something happy or frowning when I'm sad. At that point it seems like I'm merely trying to appease the technology to make it work, instead of just doing my natural thing and it picking up on that.

    Don't complain to me. That's what the summary said.

    As for EEG, I wonder what mine looks like when I'm playing Poker.

    I bet it's not too readable. I'm pretty good; mechanistic even when I'm bluffing.
