Ahead of its planned announcement this month, Google apparently accidentally published a blog post on Tuesday with details about the thinking behind the development of Material 3 Expressive, its open-source design system.
The post shared research behind the design of the interface, as first reported by 9to5Google, which shared the now-deleted post saved in the Wayback Machine. The thought process behind the company's "expressive design" involved making the user interface easier to use and less "boring," according to the post.
"The fundamental parts of expressive design are the use of color, shape, size, motion and containment," the post said. "These design aspects are also fundamental to what makes a product more usable by drawing attention to what matters in the interface: Making key actions stand out, and grouping like elements together."
The post noted that the elements researched included:
- Progress indicators: Which ones made the waiting time feel faster?
- Buttons: How big can they get to improve tap time without overwhelming the screen?
- Floating toolbars: How can they be noticeable and usable?
Google did not immediately respond to a request for comment.
