Android Wear, Google's new platform for wearables, is fascinating stuff. We got to see a lot of it yesterday, but we didn't get to spend a lot of time with the user interface itself because the watches were on retail mode -- a limited version of the firmware. This is no longer a problem, as Samsung demoed its brand new Wear-laden smartwatch, known as the Gear Live, for Engadget. Once you're done checking out our walkthrough of the UI below, we recommend you also take a closer look at our other coverage of Android Wear devices from yesterday. In the meantime, however, head below for a photo gallery and five-minute tour of Google's new platform.
