Sick of your friends saying you look fat in those jeans? Apparently, NTT DoCoMo feels your pain and aims to swap out the peer criticism with smartphone objectivity. Shown off in advance of CEATEC Japan 2011 (an annual electronics trade show), the operator took the wraps off several mobile-based accessories, ranging from gamma ray and UV light monitoring phone cases to a breathalyzer-like add-on for measuring body fat (you paying attention, HTC Rhyme?). There were also a couple of applications on hand for checking photos of food against a calorie database à la Google Goggles, and an AR implementation for weather services on tablets. It's not clear whether the Japanese carrier actually intends to release these innovations to the mass-consuming public, but as with all things tech in that corner of the world, they're sure to get it before we ever do. Jump past the break for a video peek at Nippon's creep towards a Hitchhiker Guide-style wireless world.
