user interface [as defined by caylie, ashley, steven, and sarah]
The conversation between humans and machines to guide a user through a specific, visual organization of information. Their goal is to be logical, dependable, visual and conversational in the design of human-machine interface. When using a specific interface the user expects the menu button to be a menu, not open to another page. These expectations create a logical basis for all decisions in designing the interface. This consistency also makes it dependable, when the user clicks on the menu button they’re given a menu option. This creates familiarity and plays off of knowledge that the user already has. The conversation between the humans and machines creates an experience by using visuals in a methodical, intentional way. The UI designer transfers the information to a visual language in a way designed around its user.
