Android Wear can do a whole lot more using your wrist
That big Android Wear update isn't just about allowing cellular data on smartwatches -- it's also really helpful if you don't have a hand free. Google has quietly revealed that Android Wear 1.4 has a ton of new wrist gestures beyond the usual flicks to navigate cards. You can take action on a card by pushing your arm down, for instance, or go back to your watch face by wriggling your wrist. You're probably going to look silly if you use nothing but wrist gestures, but this beats dropping a bag (or freezing your hands) just to touch your watch for a brief moment.
