User Interface Design is a process of visually guiding the user through a product’s interface via interactive elements and across all sizes/platforms. User Interface Design is a digital field, which includes responsibility for cooperation and work with developers or code.
User Experience Design
So, where does design fit in with all that? UXD (user experience design) is about designing specifically for the needs of the user or customer, looking at things like ease of use, quality, and efficiency.
In order for humans to make the most out of complex systems like websites and computer programs (or any product, really), designers had to start thinking about how people interact with those same products. They looked for ways to make those interactions as intuitive and straightforward as possible.
