This is really cool--it's essentially an audio QR code--and I think could improve the user experience across a number of apps.

  So cool! I can't wait until the phone can detect EEG frequencies to guess what I might be thinking so that it can then bombard me with ads about shit I didn't even know I wanted! Bonus points for messaging all my friends on Facebook to let them know I just was thinking about kinky porn! It sure would take all the work out of making decisions (like what I may or may not like) or having to deal with all the pesky extra money and friends I have now!

    Surely OP didn't mean to celebrate being tracked by advertisers. Emotional reactions are understandable, but if you take a step back, the technology could be used in a very different way. The problem is not that it uses sounds which are difficult to hear. The problem is that it does this without user's consent.

      Thank you, and yes I should clarify that I'm against that kind of espionage use. It's the technology itself that seems promising for other purposes.

  Except with a QR code, I have to physically turn on my camera and point it to the QR code, i.e. I have to intend to process the QR code. Inaudible audio seems to be something that would not require user intention.

    That's what I think is so cool about it -- half the issue with QR codes is that you have to open an app, point a camera at it, focus, and take a picture. With this technology, you don't have to do any of those things. Nor do you have to get on the same wifi, figure out how to bluetooth pair, or anything else like that.
