UX stands for User Experience and UI stands for User Interface. Many people think of these as the same thing, but they are quite different. User Experience is the overall impression one has from all interactions with a company or product while the User Interface is the actual assets which make up the physical or virtual interface. This class focuses on user interface design, but it is impossible to design user interfaces in a vacuum without taking into account how one is changing the user experience. In large companies, these are completely different fields and breakdown into even more specific roles such as a UXR (user experience researcher) or an interaction designer. In smaller companies, one person may complete all roles.
