User interface

Definition

A user interface (UI) is the point of interaction between the user and a digital device or application, encompassing all the visual elements, buttons, and controls that allow users to navigate and communicate with the software. The design of a UI is crucial in enhancing the user experience, as it determines how easily users can access features and accomplish their tasks on mobile platforms and apps.
