Note: User Interface (UI, User Interface) design is one of several interdisciplinary disciplines involved in designing software products. Whether it is User Experience (UX, User Experience), Interaction Design (ID, Interaction Design), or Visual / Graphic Design (Visual / Graphic Design), user interface design can be involved.

1. What is User Interface Design?

Broadly speaking, the user interface is the medium through which humans and machines communicate. The user sends a command to the machine, and the machine starts a process, replies with information, and gives feedback. Users can make decisions about the next action based on user feedback.

Human-computer interaction (HCI, Human Computer Interaciton) is mainly concerned with digital interfaces, that is, punching machines in the past, command lines, and graphical interfaces (GUI, Graphic Design) today.

User interface design for digital products mainly focuses on the layout, information structure, and display of interface elements on display screens and various terminal platforms. Video games and TV interfaces are also included.
