UI is short for UserInterface. UI design can be divided into entity UI and virtual UI. The UI design mentioned in the Internet is virtual UI, which generally refers to the overall design of human-computer interaction, operation logic and beautiful interface of software. Good UI design not only makes the software personalized and tasteful, but also makes the operation of the software comfortable, simple and free, which fully embodies the positioning and characteristics of the software.

Software design can be divided into two parts: coding design and UI design. The original intention of UI is user interface, which is the abbreviation of English user and interface.
