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

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.

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.

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

Depth · Distinct visual layers and realistic motion convey hierarchy, impart vitality, and facilitate understanding. Touch and discoverability heighten delight and enable access to functionality and additional content without losing context. Transitions provide a sense of depth as you navigate through content.

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.

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

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.

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.

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.

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.

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.

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.

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.

I was a 'Laurel and Hardy' nut. I got to know Laurel at the end of his life, and it was a great thrill for me. He left me his bow tie and derby and told me that if they ever made a movie about him, he'd want me to play him.

Once I realized that right thinking is vital to victorious living, I got more serious about thinking about what I was thinking about, and choosing my thoughts carefully.

I love 'Girls.' The writing is so clever. I think Lena Dunham is a genius. I can't believe she writes it, directs it and stars in it. It's really exciting that a young woman has been able to achieve all of that.

What Britain needs is an iron lady.

Seeing how easy it has been to use Twitter for good has exposed the double-edged sword of how easy it could be to co-opt.

Attachment parenting demands not just certain actions you take with your baby but also certain emotional states to accompany those actions.

I wanted to become a cartoon artist, a portrait artist, and an illustrator. This was my first idea.

I saw what looked like another fallen tree in front of me and put my foot on it to cross over. At that moment it reared up in front of me-the biggest python I had ever seen!

If you could choose one characteristic that would get you through life, choose a sense of humor.

Everything is being run by computers. Everything is reliant on these computers working. We have become very reliant on Internet, on basic things like electricity, obviously, on computers working. And this really is something which creates completely new problems for us. We must have some way of continuing to work even if computers fail.

I like someone who's focused and can tell me what they've done well and not well and who's very open, honest, and self-aware.
