What do UI Designers do?

UI designers take prototypes and sketches to the next level by ensuring that customers feel completely in their element when navigating your website. It’s not just nice-looking images, warm backgrounds, and flat or material experience design. It’s creating an emotional state for the user to feel 100% confident when using your website or mobile app.
To end all confusions, User Interfaces are the tools a person uses to accomplish a task or set of tasks, and User Experience is how a person feels when using those tools. Based on this definition and the story, we can see that anyone can design a trip (an interface and an experience) but only the ui design that accomplished the goals and considers all aspects, will let the user experience something magical.
