Well, that's why I go to conferences like CTIA 2010, to see a headphone control of man with his eyes.

Yes, true, and it was exhibited at the booth of NTT DoCoMo. Here's how it works. Obviously, it can detect eye movements by electrodes. Eyeballs positive electrical potential, the cone, and his negatives in the retina. If the eyes are forward-looking statements, which carry both a neutral charge. If you look left, bear left a positive charge and the right side is a negative element. If you look right, the charges on the positive side of the desk in front of the right and the left side is negative.

The charge around the eye changes with eye movements, and this signal is received by an electrode as electroculogram (EOG). To move your eyes quickly from side to side as pressing play or pause. Two of the rapid legal change, follow the advancing front, and move his eyes set in a circle around the volume.

If you think I'm joking with this report, I am not. These two diagrams on the left side of the man who is in the photo my source material. If it is a lie, then I am, but I'm only repeating what I saw.

Are we at the time when the controls for the headphones are on our eyes? I'll just stay here.
