Clarity · Throughout the system, text is legible at every size, icons are precise and lucid, adornments are subtle and appropriate, and a sharpened focus on functionality motivates the design.

Apple

Clarity · Negative space, color, fonts, graphics, and interface elements subtly highlight important content and convey interactivity.

Apple

Deference · Fluid motion and a crisp, beautiful interface help people understand and interact with content while never competing with it. Content typically fills the entire screen, while translucency and blurring often hint at more.

Apple

Deference · Minimal use of bezels, gradients, and drop shadows keep the interface light and airy, while ensuring that content is paramount.

Aesthetic integrity · It represents how well an app’s appearance and behavior integrate with its function. For example, an app that helps people perform a serious task can keep them focused by using subtle, unobtrusive graphics, standard controls, and predictable behaviors.

Apple

Aesthetic integrity · An immersive app, such as a game, can deliver a captivating appearance that promises fun and excitement, while encouraging discovery.

Torsten Caspar

Consistency · A consistent app implements familiar standards and paradigms by using system-provided interface elements, well-known icons, standard text styles, and uniform terminology. The app incorporates features and behaviors in ways people expect.

Apple

Direct Manipulation · The direct manipulation of onscreen content engages people and facilitates understanding. Users experience direct manipulation when they rotate the device or use gestures to affect onscreen content. Through direct manipulation, they can see the immediate, visible results of their actions.

Apple

Feedback · It acknowledges actions and shows results to keep people informed. The built-in iOS apps provide perceptible feedback in response to every user action.

Apple

Feedback · Interactive elements are highlighted briefly when tapped, progress indicators communicate the status of long-running operations, and animation and sound help clarify the results of actions.

Apple

Metaphors · People learn more quickly when an app’s virtual objects and actions are metaphors for familiar experiences—whether rooted in the real or digital world.

Torsten Caspar

Metaphors · They work well in iOS because people physically interact with the screen. They move views out of the way to expose content beneath. They drag and swipe content. They toggle switches, move sliders, and scroll through picker values. They even flick through pages of books and magazines.

User Control · Throughout iOS, people—not apps—are in control. An app can suggest a course of action or warn about dangerous consequences, but it’s usually a mistake for the app to take over the decision-making. The best apps find the correct balance between enabling users and avoiding unwanted outcomes.

Apple

User Control · An app can make people feel like they’re in control by keeping interactive elements familiar and predictable, confirming destructive actions, and making it easy to cancel operations, even when they’re already underway.

Largely in the beginning, I did a lot of extra work because I was lighter than all the other guys. I was at a massive disadvantage, so I had to put on weight. I started with eating. I had to really focus on my diet.

David Robinson

For me, I love food. It's my greatest pleasure and also the thing that could ruin you as well. It's one of those things where, if you're not thoughtful about it, it could be unhealthy. But if there's a mindfulness about it; it actually is a wonderful tool of emotional expression.

John Amery

I've lost perspective on what I'm doing. I think it's good for me to take a break and reassess why I'm doing it and how I'm doing it. And I think this is probably a good way to learn about that. I need a break from myself as much as I imagine the audience does.

Ryan Gosling

In my case, of course, people had a lot of expectations, but that didn't pressurise me because I'm pretty confident about my musicality and my talent.

Bhagavad Gita

We are not here to curse the darkness but to light the candle that can guide us thru that darkness to a safe and sane future.

Serinda Swan

Hinduism dies if untouchability lives and untouchability has to die if Hinduism is to live.
