Easing functions

Easing functions specify the rate of change of a parameter over time.

Objects in real life don’t just start and stop instantly, and almost never move at a constant speed. When we open a drawer, we first move it quickly, and slow it down as it comes out. Drop something on the floor, and it will first accelerate downwards, and then bounce back up after hitting the floor.

This page helps you choose the right easing function.

Material design principles

Design is the art of considered creation. As designers, our goal is to satisfy the diverse spectrum of human needs. As those needs evolve, so too must our designs, practices, and philosophies.

We challenged ourselves to create a visual language for our users that synthesizes the classic principles of good design with the innovation and possibility of technology and science. The result is material design: a cross-platform design system grounded in tactile reality, inspired by our study of paper and ink, yet open to imagination and magic.

In this session, design leads across Google discuss the key principles of material design, and set the stage for the later sessions focusing on interaction, motion and visual design.

Pablo Picasso’s The Bull to explain the design process

Picasso’s The Bull, created in late 1945, reveals how a great artist turns an idea into a masterpiece. Starting the series with a realistic drawing of a bull, Picasso used the following 10 lithographs to mutate and dissect its form, stripping away details and stylizing its anatomy. In the end, Picasso turned a highly literal representation of a bull into an intertwined series of abstract elements that balance and counterbalance each other to make up a powerful and expressive work of art. The last image is a single sinuous line that is still unmistakably a bull.

Many artists have studied The Bull over the years. It is almost a master class in its own right on the artistic process. (You can read more analysis about The Bull here.)

At Apple University, “The Bull” is used as a way to explain the company’s design ethos, which Jony Ive once described as "A Thousand No’s for Every Yes."

“You go through more iterations until you can simply deliver your message in a very concise way, and that is true to the Apple brand and everything we do,” one person who took the course told the Times.

Steve Jobs was influenced by 20th-century European artists. In fact, the original Mac logo from 1984 was inspired by Picasso’s contemporary and sometimes rival, Henri Matisse. That logo, incorrectly, is usually credited as the “Picasso logo” but the Spanish painter’s legacy is obviously still alive and well at Apple.
