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.

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.

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

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 · 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.

Before Medicare, nearly half of American seniors were forced to go without coverage because insurance companies were reluctant to insure them - making the chances of having health insurance as a senior the same as getting tails on a coin flip.

The truth is that my grandfather was quite wealthy, a shipbuilder.

Your body is a temple, but only if you treat it as one.

Don't believe your own publicity. You can't; you'll start thinking that you're better than you are.

Throughout my career as a lawyer, teacher and labor leader, books have remained my constant companion - stuffed into a briefcase, overflowing on my bedside table, stacked on my desk at work. Books have carried me to distant worlds, opened new doors and made me feel empathy, compassion, anger, fear, joy, acceptance - and everything in between.

I'd love a signed first edition of 'City of Glass' by Paul Auster. My favourite book of all time.

I hate to think of a day where a compelling book or a compelling authorial voice would be lost simply because that person doesn't have a Web site. But I think that, to use the Internet in a positive way, to turn people on to reading, is something that authors shouldn't really shy away from necessarily.

The criminal law needs to be improved to meet new forms of crime, but to denounce financial devices which are useful and legitimate because use is made of them for fraud, is ridiculous and unworthy of the age in which we live.

I wasn't there to compete. I was there to win.

Human beings have to create hope. They have to. You have to have something you hold onto as being a possibility. Otherwise, why go on?

If there is any form of contagion that is adaptive, it is the immediate response to the fear of others. If others are fearful, there may be good reason for you to be fearful too.

Unlike the puerile loyalty to a conviction, loyalty to a friend is a virtue — perhaps the only virtue, the last remaining one.

It's harder to make real audio than special effects audio.

I've got the big name, but I've always wanted to be in a band, one of a band.

For Arkansas, I think the sky is the limit, but I think we are going to have to fight the urge to avoid risks. We need to look first at where we are as a state. I think, as a state, we have made progress over the years, but there are two kinds of progress: absolute progress and relative progress.

I'm a one-nation Tory.

On Saturday afternoons when all the things are done in the house and there's no real work to be done, I play Bach and Chopin and turn it up real loudly and get a good bottle of chardonnay and sit out on my deck and look out at the garden.

I manage to scrape together a private life, despite the press.

I was always led to believe you should take care of yourself, trust in your abilities and you're the author of your own destiny.

I have always let my motivation guide me, and that has served me well. Climbing has taught me how to thrive and created a life that I feel incredibly lucky to have.

One question about a joke is, how well is the strangeness of the situation resolved? At 'The New Yorker', we retain a lot of incongruity, tapping the playful part of the mind - Monty Python-type stuff. We also try to use humor as a vehicle for communicating ideas. Not editorial comment, but observation.

Botox, I think, is poison, I would never put it into my face, and I'm needle-phobic. I spend a lot of time keeping my face out of the sun and taking care of my skin and wearing make-up.

I get interested in the various ways that music is being done in the culture, and some of it I like thoroughly enough to want to learn about it. The way I have been successful at doing that is to become part of it.

I love Nelly. He's such a great performer. He's so hyper and so am I.
