The rise of interaction design in China is mainly in the past 10 years, mainly due to the rise of smart mobile devices (especially smart phones) and continuous changes and updates. And as people continue to rely on the mobile Internet, including mobile devices such as mobile phones and tablet computers. These devices have become the medium for the mobile Internet to interact with people, so the interactive experience of the mobile phone system becomes more and more important.
In China, from the perspective of interaction designers, interaction design can make products easier to use, make users more happy when using products, and meet users' goals and expectations. Interaction designers design various effective interaction design methods by understanding the psychological and behavioral characteristics of "people" themselves and combining their own inspiration.
What is "goal-oriented" interaction design?
Alan Cooper, the author of the "Father of Interaction Design", once said in the book "About Face 4 The Essence of Interaction Design" that a new type of design based on "object-oriented design", its main connotation is: behavior-oriented, and provide complete design process to better understand user goals, needs, and motivations. To understand the process of goal-directed design, it is first necessary to better understand the nature of user goals, the mental models that generate user goals, and how user goals become the key to designing interactive behaviors  .
"Goal-Oriented" Interaction Design Process
According to the book "About Face 4: The Essentials of Interaction Design": "Few of current design methodologies efficiently and systematically translate the information gathered during the research phase into detailed design specifications, in part because: for a long time, , designers do not participate in the user research process and can only rely on third-party descriptions of user behavior and expectations. Also, there are not many ways to capture sustainable behavior and properly know the product definition, most of which do not provide information about user goals. Instead, it provides some task-level information. This information can help clarify interface layout, workflow, and translate functionality into interface controls, but it is also important in determining what the product is, what it can do, and how it should satisfy users. of broad b2b data needs, but of little use.” 
In addition, according to practical experience, the interaction design process of most domestic companies is often "top-down" or "purposeless". The so-called "top-down" refers to the interaction design process in the mouth of a leader or a boss, and subordinates can follow it step by step; while "aimless" means that the interaction design team does not really understand and clearly understand the interaction design. Purpose, task, core and needs, complete the interaction design process with their own work experience and habits. These two situations often bring two extremes. On the one hand, the product is designed to meet the "taste" of the leader or the boss without truly understanding the needs of the user, resulting in the product not adapting to the market and causing it to fail; on the other hand, because the team does not understand Unification, different design styles or mismatches with needs, too much attention to some details that are not the real core, etc., cause the product interaction design process to be slow, or even postponed indefinitely, so that it cannot be launched in time and fails.
