Interaction design , or IXD, is a design field that defines and designs the behavior of man-made systems. It defines the content and structure of communication between two or more interactive individuals, so that they can cooperate with each other to achieve a certain purpose together. Interaction design focuses on "embedding information technology in a material world full of social complexity" and strives to establish meaningful relationships between people, products and services. Its goal can be analyzed from the two levels of "usability" and "user experience", focusing on user-oriented needs.



Human-Computer Interaction, Human-Computer Interaction (HCI or HMI for short) is a science that studies the interactive relationship between a system and users. The system can be a variety of machines or computerized systems and software. The human-computer interaction interface usually refers to the part visible to the user. The user communicates with the system through the human-computer interaction interface and performs operations. It could be something as small as a radio button, or as large as the dashboard of an airplane or a power plant control room. For the usability and user-friendliness of the system, the design of the human-computer interaction interface needs to include the user's understanding of the system.



Industrial design (ID for short) refers to the design of industrial products based on engineering, aesthetics, and economics. Industrial design is divided into four categories: product design, environmental design, communication design, and design management; including modeling design, mechanical design, circuit design, clothing design, environmental planning, interior design, architectural design, UI design, graphic design, packaging design, and advertising Design, animation design, display design, website design, etc.



The feeling when people interact with the system is the user experience (UX). Websites, Web applications, and desktop programs are all systems, which are commonly referred to as human-computer interaction in the concept. UX designers research and evaluate the user experience of a system, focusing on the ease of use, value manifestation, practicality, and efficiency of the system. Designers may also focus on the subsystems or processes of a system. For example, they might study the checkout process of an e-commerce site and observe whether the process is user-friendly and easy to use. They can study the components of the subsystem in more depth, such as studying how users are more efficient and comfortable when filling out Web forms.
