Based on the concept of goal-oriented design,the paper takes TikTok,this short video APP,as the research object to explore the key points of its interactive interface design.After system analysis,an interaction design framework based on user goals is proposed,which is enough to improve the user experience.At the same time,in order to more intuitively explain the APP lication process of the interaction design framework,the content of the interaction design is refined from the function,interface layout,operation and other aspects around the TikTok interaction interface.Finally,the scientific APP lication of the goal-oriented concept can significantly improve user satisfaction.
