Once upon a time, Microsoft came up with an interface that it called Metro. (People still call it that even though the term turned out to have trademark problems.) Today at its Build conference, the company previewed Fluent Design, its new design language for Windows.
Fluent embraces some of the same concepts as Google's Material Design, such as using layers, animation, and other elements to create interfaces that have an almost cinematic feel. But it's not a mere knockoff, and Microsoft gave a lot of thought to how to incorporate pen input—a technology the company has been fascinated by for well over a quarter century.
