| |
| <p>These design principles were developed by and for the Android User Experience Team to keep users' |
| best interests in mind. Consider them as you apply your own creativity and design thinking. Deviate |
| with purpose.</p> |
| |
| <h2>Enchant Me</h2> |
| |
| <div class="layout-content-row"> |
| <div class="layout-content-col span-7"> |
| |
| <h4>Delight me in surprising ways</h4> |
| <p>A beautiful surface, a carefully-placed animation, or a well-timed sound effect is a joy to |
| experience. Subtle effects contribute to a feeling of effortlessness and a sense that a powerful |
| force is at hand.</p> |

| <div class="layout-content-col span-7"> |
| |
| <h4>Real objects are more fun than buttons and menus</h4> |
| <p>Allow people to directly touch and manipulate objects in your app. It reduces the cognitive effort |
| needed to perform a task while making it more emotionally satisfying.</p> |
| |
| </div> |

| <h4>Let me make it mine</h4> |
| <p>Let people add a personal touch because it helps them feel at home and in control. Think about |
| subtle ways to offer personalization while providing sensible and beautiful default functionality.</p> |

| <p>Learn peoples' preferences over time. Rather than asking them to make the same choices over and |
| over, place previous choices within easy reach.</p> |

| <h2>Simplify My Life</h2> |
| |
| <div class="layout-content-row"> |
| <div class="layout-content-col span-7"> |
| |
| <h4>Keep it brief</h4> |
| <p>Use short phrases with simple words. People are likely to skip sentences if they're long.</p> |
| |
| </div> |
| <div class="layout-content-col span-6"> |
| |

| |
| <h4>Pictures are faster than words</h4> |
| <p>Consider using pictures to explain ideas. They get people's attention and can be much more efficient |
| than words.</p> |
| |

| <div class="layout-content-col span-6"> |

| <div class="layout-content-col span-7"> |
| |
| <h4>Decide for me but let me have the final say</h4> |
| <p>Take your best guess and act rather than asking first. Too many choices and decisions make people |
| unhappy. Just in case you get it wrong, allow for 'undo'.</p> |
| |
| </div> |
| <div class="layout-content-col span-6"> |

| <div class="layout-content-col span-7"> |
| |
| <h4>Only show what I need when I need it</h4> |
| <p>People get overwhelmed when they see too much at once. Break tasks and information into small, |
| digestible chunks. Hide options that aren't essential at the moment, and teach people as they go.</p> |
| |
| </div> |

| <div class="layout-content-row"> |
| <div class="layout-content-col span-7"> |
| |
| <h4>I should always know where I am</h4> |
| <p>Give people confidence that they know their way around. Make places in your app look distinct and |
| use transitions to show relationships among screens. Provide feedback on tasks in progress.</p> |
| |
| </div> |
| <div class="layout-content-col span-6"> |

| <div class="layout-content-col span-7"> |
| |
| <h4>Never lose my stuff</h4> |
| <p>Save what people took time to create and let them access it from anywhere. Remember settings, |
| personal touches, and creations across phones, tablets, and computers. It makes upgrading the |
| easiest thing in the world.</p> |
| |
| </div> |

| <div class="layout-content-col span-7"> |
| |
| <h4>If it looks the same, it should act the same</h4> |
| <p>Help people discern functional differences by making them visually distinct rather than subtle. |
| Avoid modes, which are places that look similar but act differently on the same input.</p> |
| |
| </div> |
| <div class="layout-content-col span-6"> |

| |
| <h4>Only interrupt me if it's important</h4> |
| <p>Like a good personal assistant, shield people from unimportant minutiae. People want to stay |
| focused, and unless it's critical and time-sensitive, an interruption can be taxing and frustrating.</p> |
| |

| <h2>Make Me Amazing</h2> |
| |
| <div class="layout-content-row"> |
| <div class="layout-content-col span-7"> |
| |
| <h4>Give me tricks that work everywhere</h4> |
| <p>People feel great when they figure things out for themselves. Make your app easier to learn by |
| leveraging visual patterns and muscle memory from other Android apps. For example, the swipe gesture |
| may be a good navigational shortcut.</p> |
| |

| |
| <div class="layout-content-row"> |
| <div class="layout-content-col span-7"> |
| |
| <h4>It's not my fault</h4> |
| <p>Be gentle in how you prompt people to make corrections. They want to feel smart when they use your |
| app. If something goes wrong, give clear recovery instructions but spare them the technical details. |
| If you can fix it behind the scenes, even better.</p> |

| <div class="layout-content-col span-7"> |
| |
| <h4>Sprinkle encouragement</h4> |
| <p>Break complex tasks into smaller steps that can be easily accomplished. Give feedback on actions, |
| even if it's just a subtle glow.</p> |
| |
| </div> |
| <div class="layout-content-col span-6"> |

| |
| <h4>Do the heavy lifting for me</h4> |
| <p>Make novices feel like experts by enabling them to do things they never thought they could. For |
| example, shortcuts that combine multiple photo effects can make amateur photographs look amazing in |
| only a few steps.</p> |
| |
| </div> |

| |
| <h4>Make important things fast</h4> |
| <p>Not all actions are equal. Decide what's most important in your app and make it easy to find and |
| fast to use, like the shutter button in a camera, or the pause button in a music player.</p> |
| |
