Eye for electronics

Rolling your eyes to turn up the volume of a portable music player and tapping your fingers to turn on a DVD player are among technologies that a Japanese mobile carrier is testing for wearable gadgets. The sensors and chips that are inculcated inside the headphones detect electrical current produced by movements of the wearer’s eyeballs. This wearable control technology will be adapted for mobile devices that download music, play video games and allow users to shop online and keep up with their email. The technology may enable cell phone cameras to read bar codes to get product information, download music and coupons when the user simply looks at the codes.
