date pickers, toggles and switches, and reduced the border thicknesses for all user interface elements. Principles Microsoft's design team cites as an inspiration for the design language signs commonly found at public transport systems. The design language places emphasis on good typography and has large text that catches the eye. Microsoft sees the design language as "sleek, quick, modern" and a "refresh" from the icon-based interfaces of Windows, Android, and iOS. All instances use fonts based on the Segoe font family designed by Steve Matteson at Agfa Monotype and licensed to Microsoft. For the Zune, Microsoft created a custom version called Zegoe UI, and for Windows Phone Microsoft created the Segoe WP font family. The fonts mostly differ only in minor details. More obvious differences between Segoe UI and Segoe WP are apparent in their respective numerical characters. The Segoe UI font in Windows 8 had obvious differences – similar to Segoe WP. Characters with notable typographic changes included 1, 2, 4, 5, 7, 8, I, and Q. Joe Belfiore was one of the architects of Metro. At Nokia World 2011, Belfiore explained that the UI aims to be "artistic" in textual elements and iconography. He also mentioned the "motion" of the UI, specifically in Windows Phone, of the Live Tiles, moving dots, and kinetic scrolling. Microsoft designed the design language specifically to consolidate groups of common tasks to speed up usage. It achieves this by excluding superfluous graphics and instead relying on the actual content to function as the main UI. The resulting interfaces favor larger hubs over smaller buttons and often feature laterally scrolling canvases. Page titles are usually large and consequently also take advantage of lateral scrolling. Animation plays a large part. Microsoft recommends consistent acknowledgement of transitions, and user interactions (such as presses or swipes) by some form of natural animation or motion. This aims to give the user the impression of an "alive" and responsive UI with "an added sense of depth". Reception On mobile Early response to the language was generally positive. In a review of the Zune HD, Engadget said, "Microsoft continues its push towards big, big typography here, providing a sophisticated, neatly designed layout that's almost as functional as it is attractive." CNET complimented the design language, saying, "it's a bit more daring and informal than the tight, sterile icon grids and Rolodex menus of the iPhone and iPod Touch." At its
