While head-mounted displays are nothing new, LG has patented a novel method for utilizing them that might grab your attention. The patent states that when you're staring at content on a device like a tablet, the HMD is inactive. But turn your head or the device away and that same content will automatically fade into view right in front of your bespectacled eyes. According to the filing, the noggin-strapped contraption is set to buzz as it switches displays and there'll be a slight transitional pause when viewing video. While we're betting virtual reality goggles and Google-branded headgear might prove to be a touch more popular, this is at least a lot cooler than passive 3D clip-ons.
