User experience is like the black hole of computing. It's impossible to see, but you know it's there. But what is user experience? A computing system and application design concept studies and evaluates human feelings and expressions when using such techniques. It helps us facilitate and enable the development of computing systems centered on ease of use and accessibility for a human user. When talking about UX, we usually mean the user interface (UI), which consists of all aspects of an interactive system—including hardware, software, content, graphical design, sound design, and typography—that users interact with when interfacing with a computer program or system. UX is the art of making technology human. It's how you make your product or service feel like part of your customer's life, a natural extension of them and their world. UX is the critical role of a UX designer, who studies what your customers do with your product or service—how they feel while doing it, how they react to its design, and what they need from it to function in their daily lives. As a UX designer, you'll be responsible for everything from defining the overall structure and flow of a website or app to creating personas so that developers can build features around actual people instead of abstract ideas about what might work best for everyone. UX is a broad concept. It's not just about making things pretty. It's about ensuring your users are happy and can do what they need to do without getting frustrated or confused by the interface. It's about providing that the system works for them, not just you. It's ensuring the end-user gets what they want from the experience, whether entertainment, utility or a combination of both. UX is more than just the visual appeal of your website. UX design focuses on the overall flow of an interface so that users will find it easy to navigate the choices available and make purchases.
