This is some really interesting techonology from NTT Docomo that allows you to change your music on your ear buds by moving your eyes about. Here it is in video form. One of the most interesting aspects is learning that the cornea emits different electro-charges depending on how you move your eyes. The ear buds can measure those changes and will tell your mp3 player (okay fine, most likely your ipod or iphone . . . but maybe the new windows 7 phone?) to up the volume or flip the track ahead, etc. Evidently this is just a prototype though and NTT does not have any immediate plans to move them into production, but that can change . . .
