Some characteristics and advantages of human-computer interaction interface design based on scenic spot guidance, in order to better apply human-computer interaction interface in product usability, the user model, user interface model, multi-channel interaction information integration, pen-based interaction technology, human-computer interaction software architecture and other contents in human-computer interaction are analyzed. It solves the problem of product homogeneity caused by traditional cognitive interaction and makes the design of interactive products return to focusing on users and interaction itself. The feasibility and rationality of the interactive product design method based on usability theory are verified through design practice, and this method has certain guiding significance.
