Microsoft’s support for Android Wear smartwatches isn’t limited to a handy OneNote app. The company’s research wing has slipped out Analog Keyboard, a prototype input app that has you drawing individual characters on your wristwear instead of trying to hit tiny keys. It’s not the fastest solution, but it’s very straightforward — you get a relatively big drawing area, and there’s a smart auto-correct system that you turn off just by pausing for a while between letters.
