The Bauhaus Design School was known for its emphasis on reduction, and the desire to make function and form beautiful.
Swiss design focuses on using a crisp, clean typography that calls for bold visuals and design. It is commonly used for signage in and around subway stations, airports, and city iconography. These signs help people navigate through a city, much like the Metro Style can help users find their way through a well designed interface.
The idea is to have type that offers information while evoking emotion to users. By inviting users on a personal journey, you're creating movement through design.
