On February 10, 2012, the US Patent & Trademark Office published a patent application from Apple that reveals a hot 3D eye-tracking based interface that will be used for gaming, digital photography and videography, biometrics and surveillance applications while being an OS feature option for iOS devices and Apple's iMac. The technology may work in conjunction with Apple's previous work on 3D which touched on head tracking and unique ambient light feature technologies. Apple wowed us earlier this year with a patent which demonstrated that they're paving the way for a new 3D GUI. Today's patent adds fuel to that fire. Apple's 3D GUI patent trend is really picking up momentum and you have to wonder when they'll release this beast into the wild!
