user experience design is the process of planning the experience a person has when they interact with a product.
UX design focuses on the interaction that a human user has with everyday products and services. The goal of UX design is to make using these products and services, both digital or physical, easy, logical, and fun.
UI (User Interface) design is the user-centered approach to designing the aesthetics of a digital product. In essence, they create the look and feel of a website or application’s user interface. An interface is the graphical layout of the application. These interfaces should not only be functional, but they should be easy to use and visually appealing.
UX designers act as advocates for the user. Sometimes, you (the user) feel like you’re the problem when you can’t figure out how to use a product or website. Most of the time, though, it’s not your fault. It’s the UX designer’s job to design with you in mind. They are there to make products and technology not only useful, but enjoyable and easy to use.
