“Japanese wireless carrier NTT DoCoMo unveiled prototype headphones that enable wearers to control handheld music players or phones with their eyes. The headphones monitor eye movements by sensing changes in electric currents in the cornea and retina. For example, a user can pause a music player by looking from right to left. By looking to the right twice, the player will skip to the next track. Rolling eyes clockwise raises the volume. The headphones were also demonstrated operating a cell phone.”
