At a high level, the Android Wear UI consists of two 13main spaces centered around the core functions of <strong>Suggest</strong> and 14<strong>Demand</strong>. Your application will have an important role to play in both of these 15spaces.</p> 16 17 18 19<h3 id="Stream">Suggest: The Context Stream</h3> 20 21<div class="wear-inset-video-container" style="float:right;margin:0 -22px 60px 40px"> 22 <img class="wear-bezel-only" src="{@docRoot}wear/images/screens/bezel.png" alt=""> 23 <img class="gif" src="{@docRoot}wear/images/screens/stream.gif"> 24</div> 25 26<p>The context stream is a vertical list of cards, each showing a useful or timely piece of 27information. Much like Google Now on Android phones and tablets, users swipe vertically to navigate 28from card to card for a brief and comprehensive update about what's important to them. Only one card 29is displayed on screen at a time, and background images are used to provide additional visual 30information. Your application can create cards and inject them into the stream when they are most 31likely to be useful.</p> 32 33<p>Cards in the stream are more than simple notifications. They can be swiped horizontally to 34reveal additional pages. Further horizontal swiping may reveal tappable buttons, allowing the user 35to take action on the notification. Cards can also be dismissed by swiping left to right, removing 36them from the stream until the next time they have useful information to display. 37In the emulator, hovering the mouse over the top of the screen illuminates a blue bar at 38the top of the device that takes you home when clicked.</p> 39 40 41 42<h3 id="CueCard">Demand: The Cue Card</h3> 43 44<div class="wear-inset-video-container" style="float:right;margin:0 -22px 60px 40px"> 45 <img class="wear-bezel-only" src="{@docRoot}wear/images/screens/bezel.png" alt=""> 46 <img class="gif" src="{@docRoot}wear/images/screens/cuecard.gif"> 47</div> 48 49<p>For cases where the context stream can't anticipate what the user would like to do, the cue card 50allows users to speak to their device. The cue card is opened by saying, "Ok Google" or by tapping 51on the "g" icon on the home screen. Swiping up on the cue card shows a list of actions, which can 52also be tapped.</p> 53 54<p>The list of actions includes Android intents for voice actions. The upcoming Android Wear SDK 55will enable developers to match their applications to these intents so users can perform actions 56using these voice commands. Multiple applications may register for a single voice intent, and users 57will have the opportunity to choose which application they prefer to use.</p> 58 59
