We've got very few details at the moment, but Sundar Pichai is preparing to lead the Android charge into the wearable space. He announced that the company will launch a new wearable SDK for Android at SXSW Interactive. The tools will be available to download in roughly two weeks time and will expand the efforts to put Google's mobile OS on smart watches or fitness bands. Pichai definitely didn't limit Android to those two particular implementations, however. He focused heavily on expanding developers' ability to harvest data from sensors of any kind... so long as they're mounted on your body. He even suggested a future where your jacket is loaded with sensors and powered by Android.
