What is UI consistency?
But what exactly is consistency in UI design? Consistency in UI design is concerned with making sure elements in a user interface are uniform. They'll look and behave the same way. This helps constantly prove a user's assumptions about the user interface right, creating a sense of control, familiarity, and reliability.
What is consistent user experience?
Consistency is the key principle of UX design. A usable and user-friendly design always provides a consistent experience. If user has to find a new way each time to resolve a similar kind of problem while working in a design, he will get confused and frustrated at the same time.
How would you describe a good UI?
A good UI is one that allows your users to perform the intended actions effectively and efficiently, without causing unnecessary distractions. In fact, the best User Interfaces aren't necessarily the most spectacular designs, but rather the ones that render seamless user experience.
