Whenever Facebook changes its interface, it has an impact on how millions of people communicate. In this sense, user interfaces are cultural artefacts.

Avoid getting too specific at a feature level. For example, it's too specific if you say "Page navigator" and it's too high level if you try to explore "A blog builder app." The sweet spot to go for is something that is conceptual where you can explore an interaction for a concept, such as, "Exploring spatial viewing of pages".

the concept of file folders and directories, essential to previous generations’ understanding of computers, is gibberish to many modern students.

A good industrial designer understands the capabilities and limitations of the human body in manipulating physical objects, and of the human mind in comprehending mechanical models. A camera designer, for example, shapes her product to fit the human hand. She places buttons such that they can be manipulated with index fingers while the camera rests on the thumbs, and weights the buttons so they can be easily pressed in this position, but won’t trigger on accident. Just as importantly, she designs an understandable mapping from physical features to functions—pressing a button snaps a picture, pulling a lever advances the film, opening a door reveals the film, opening another door reveals the battery.

When the software designer defines the interactive aspects of her program, when she places these pseudo-mechanical affordances and describes their behavior, she is doing a virtual form of industrial design. Whether she realizes it or not. #The software designer can thus approach her art as a fusion of graphic design and industrial design. Now, let’s consider how a user approaches software, and more importantly, why.

be inspired by the untapped potential of human capabilities. Don't just extrapolate yesterday's technology and then cram people into it.

Think about what design skills are detached from materiality, and applicable to any domain. Collect methods and experience that helps you tackle uncertainty and make you more comfortable working in foggy terrain.

Depending on the design maturity of a company, a generalist might have a harder time explaining or showcasing their skills to the teams they work with, so be ready to lean in and initiate things without being asked to. People might not know what to come to you for at first.

what I’d generally expect from someone in that role is the ability to effortlessly switch perspective between an ecosystem and vision level, by way of user flows, down to detailed design, and to understand how each decision affects the next level down.

Nobody tells people who are beginners — and I really wish somebody had told this to me — is that all of us who do creative work … we get into it because we have good taste. But it’s like there’s a gap, that for the first couple years that you’re making stuff, what you’re making isn’t so good, OK? It’s not that great. It’s really not that great. It’s trying to be good, it has ambition to be good, but it’s not quite that good. But your taste — the thing that got you into the game — your taste is still killer, and your taste is good enough that you can tell that what you’re making is kind of a disappointment to you, you know what I mean? A lot of people never get past that phase. A lot of people at that point, they quit. And the thing I would just like say to you with all my heart is that most everybody I know who does interesting creative work, they went through a phase of years where they had really good taste and they could tell what they were making wasn’t as good as they wanted it to be — they knew it fell short, it didn’t have the special thing that we wanted it to have. And the thing I would say to you is everybody goes through that. And for you to go through it, if you’re going through it right now, if you’re just getting out of that phase — you gotta know it’s totally normal. And the most important possible thing you can do is do a lot of work — do a huge volume of work. Put yourself on a deadline so that every week, or every month, you know you’re going to finish one story. Because it’s only by actually going through a volume of work that you are actually going to catch up and close that gap. And the work you’re making will be as good as your ambitions. It takes a while, it’s gonna take you a while — it’s normal to take a while. And you just have to fight your way through that, okay?

I was talking recently to a friend who teaches at MIT. His field is hot now and every year he is inundated by applications from would-be graduate students. "A lot of them seem smart," he said. "What I can't tell is whether they have any kind of taste."

Mathematicians call good work "beautiful," and so, either now or in the past, have scientists, engineers, musicians, architects, designers, writers, and painters. Is it just a coincidence that they used the same word, or is there some overlap in what they meant? If there is an overlap, can we use one field's discoveries about beauty to help us in another?

“Taste is the ability to infuse a product with emotion. In a taste-based industry, its products are stripped down to their very core: how it makes its users feel. We see this phenomenon happen in books, music, movies, games and increasingly tech products

Life can be much broader once you discover one simple fact: Everything around you that you call life was made up by people that were no smarter than you. And you can change it, you can influence it

Film geeks don’t have a whole lot of tangible things to show for their passion and commitment to film. They just watch movies all the time. What they do have to show is a high regard for their own opinion. They’ve learned to break down a movie. They understand what they like and don’t like about a film. And they feel that they’re right. It’s not open to discussion. When I got involved in the movie industry I was shocked at how little faith or trust people have in their own opinions. They read a script and they like it – then they hand it to three of their friends to see what they think about it. I couldn’t believe it.

Rick Rubin on trusting your own taste: “You can’t second-guess your own taste for what someone else is going to like…Do what’s personal to you, take it as far you can go and people will resonate with it if they are supposed to resonate with it.”

I never had an arts education. I can barely draw straight lines. What I do have is a love for words, the history and delightful orgy of words, and a constant sense of discomfort about how things are hardly ever the way they should be.

I’m thinking now about how school encourages students to bullshit. I have friends who are literature teachers who constantly get frustrated by how their smart students give them stupid but vaguely plausible answers – I remember what it was like to be such a student. The student isn’t interested in being honest about his feelings – he just wants to be done with his homework and go on to play.

higher-level observations around underlying behavior.

Graduate HCI classes are far better because there is so much depth to the field. Basically, through a combination of understanding human psychology, knowing the right questions to ask, and understanding how to properly model how people will use a system you can make software that flows naturally. That last point, sometimes referred to as Cognitive Engineering, is extremely important.

Here are the adoption curves for a handful of major technologies in the United States. There are big differences in the speeds at which these technologies were absorbed. Landline telephones took about 86 years to hit 80% adoption.Flush toilets took 96 years to hit 80% adoption.Refrigerators took about 25 years.Microwaves took 17 years.Smartphones took just 12 years.Why these wide differences in adoption speed? Conformability with existing infrastructure. Flush toilets required the build-out of water and sewage utility systems. They also meant adding a new room to the house—the bathroom—and running new water and sewage lines underneath and throughout the house. That’s a lot of systems to line up. By contrast, refrigerators replaced iceboxes, and could fit into existing kitchens without much work. Microwaves could sit on a countertop. Smartphones could slip into your pocket.

If you're pursuing the career path someone else has taken, you're going to be frustrated when you don't get the same opportunities they did.

It’s not just a question of “how do we make this usable?” it’s more about “how do we make this usable for users and increase feature adoption which will drive more revenue?“

You can look at an interface and see it as a clearly signposted user journey you should follow. Or you can see it as a collection of functions and affordances to repurpose. As raw material, rather than a guided path.
