Eye-Controlled Earphones



Have you ever been listening to your ipod or MP3 player while doing something else and you wanted to change the song but your full hands weren’t able to do so? Now that problem is solved with NTT Docomo’s eye controlled earphones.

This new technology uses electrodes around the outside of the ear buds called electrooculograms (EOGs) that detect tiny differences in the electrical potential of your eyes as they move. It turns out your eyes are electrical; there’s a positive charge at your cornea and a negative charge at your retina. When you move them, you can do all sorts of things for your musical device.

For example, when you want to play or pause you have to look left and then right. To skip, you look either left or right twice, right after the other. And if you wish to change the volume you either roll your eyes clockwise or counterclockwise. You can even wink to shuffle the songs.

however, as cool as this new product sounds it is also controversial. Some may argue it’s a safety hazard as you generally need to move your eyes in everyday life. For example, if you have to cross the street but are afraid to look left and right for fear of messing up your music, you could get seriously hurt and/or die. Over all, this is a great project but you’d have to be careful with it.

    This seems like a very cool product. I would buy it or try it out when it comes out. It was very intersting to post the idea that this could be a very controversial product. Do you agree that it’s a hazard? Or do you think these are completely harmless earphone? Also, when do you think this product will come out or will it be overruled as a hazard and not be sold?

    Daniel, this is really cool! I’ve never heard of mind control! I’m wondering, does it work with all MP3 players and iPods? Or does it just work with their player?

    Wow, this sound really cool and i’d like to try it. But i am scared of the dangers, such as not looking both ways when you cross the road. Are they doing anything to improve this and make it safer? Is there any other technology like this?
