<p>Most people are used to launching apps by clicking an icon. Android Wear is different. Wearable apps are aware of the user’s context - time, location, physical activity, and so on. The apps use this information to insert cards into the stream when they become relevant. This makes Android Wear timely, relevant and very specific.</p>
<p>A classic wrist watch is designed to let you see the time in a split second and get on with what you were doing. Designing for Android Wear is no different. The less time it takes to use your software, the more time the user can be present in whatever they are doing. Android wear is fast, sharp, and immediate.</p>
<p>Android Wear is like a great personal assistant: it knows you and your preferences, it only interrupts you when absolutely necessary, and it’s always on hand to provide a ready answer. Android Wear is helpful, respectful, and responsive.</p>
<p>Staying true to the strengths afforded by a smaller form factor, Android Wear focuses on simple interactions, only requiring input by the user when absolutely necessary. Most inputs are based around touch swipes or voice, and inputs requiring fine-grained finger movements are avoided. Android Wear is gestural, simple, and fast.</p>
</div>
<p>By providing a smart connection to the rest of the world while respecting the user’s attention, Android Wear feels personal and global, simple and smart, unobtrusive and ever-ready. Applications that represent these principles will feel most at home in the overall Android Wear experience.</p>
<p>Third party apps extend Android Wear to be more specialized and helpful throughout the day. Installing apps are a way for the user to tell the Android Wear how to do that.</p>
<p>Swiping from left to right on a card causes it to be dismissed from the stream. Dismissed cards may return when they next have relevant information. State is synced between the Android Wear context stream and the notifications on the Android handheld device, so dismissing from one causes an automatic dismissal from the other.</p>

<p>Choosing an item from a list is a common interaction. The Selection List pattern (available as the <a
href="{@docRoot}training/wearables/apps/layouts.html#UiLibrary"><code>WearableListView</code></a> component) creates a simple list optimized for ease of use on a small screen where the focused item snaps to the center of the screen and a single tap selects. This widget is recommended as a common pattern for selecting items. It is used throughout the system UI, including in the list that can be accessed by swiping up on the cue card.</p>
<p>Of course, it is possible for Android Wear apps to extend themselves beyond the familiarities of these patterns. For a deeper look at the options available, see the <a href="{@docRoot}design/wear/structure.html">App Structure</a> guide.</p>

<p>Cards should be designed to be glanceable in a split second, just like reading the time on a traditional watch. In most cases a pairing of an icon and value, or a title and short caption should be enough to convey a meaningful message. Note that the background photo should also be used to convey information; backgrounds that change to reflect and support the primary message in the card work great. For example, in the case illustrated to the right, a suitable background image is chosen to reflect the severity of current traffic conditions. This is not just a nice piece of attention to detail; the background actually reinforces the message and makes the content more glanceable.</p>
<p>In cases where additional information is absolutely necessary, don’t crowd out a card layout to the point where glanceability is affected. Instead, add an additional <a href="{@docRoot}design/wear/patterns.html#Pages">page</a> (or multiple pages, if needed) to the right of the main card in the stream to which the user can swipe for more information.

<p>Wearables are personal devices by nature, but they are not completely private. If your notification serves content that may be particularly sensitive or embarrassing (such as notifications from a dating app or a medical status report), consider not displaying all of the information in a peek card. A notification could place the sensitive information on a second page that must be swiped to, or an application could show different amounts of detail in peek and focused card positions.</p>
<p>If your app allows the user to perform an action, it is necessary to provide positive feedback. Show a generic confirmation animation or create your own. A confirmation animation is an opportunity to express your app’s character and insert a moment of delight for your user. Keep animations short (less than 1000ms) and simple. Animating the confirmation icon is an effective way of transitioning the user to a new state after completing an action.</p>
