Interaction design . Interaction Design is the field of design that defines and designs the behavior of artificial systems. It defines the content and structure of communication between two or more interacting individuals to make them cooperate with each other to achieve some purpose. Interaction design strives to create and build meaningful relationships between people and products and services, centered on "embedding information technology in a material world full of social complexity". In interaction design, on the one hand, it must be designed to meet the user's operation, and on the other hand, it must also be consistent with the browsing habits of the public, so as to better guide users to browse the content on the page. At the same time, we must follow the people-oriented principle when designing, and design on the basis of practicality, convenience and fun, so as to improve the user experience and make users have better participation.
