The purpose of this study is to train students in the university's design department to organize and demonstrate the story of a user's situational intentions in the design process. The user context investigation is an integral step in any design activity, and it helps to better understand the target of the design, meet the users' needs, and provide the correct design direction in order to reduce the failure rate after a product goes on the market. Students in the design department have often been found to lack complete product design thinking, and the students' design is often out of touch with reality and cannot meet the needs of end users. The aim of this research is to investigate how to combine physical objects and augmented reality by randomly generating three-dimensional objects combining people, objects and scenes, and having students tell the user stories based on the results produced. Through logic and insight, the future is then applied to the observation of actual scenes. In this study, augmented reality and 3D printing techniques were used to create three teaching aids, each presented in a hexahedral physical form. Each teaching aid contained six randomly generated 3D objects. The random control was thus the students who had a total of 216 permutations. The results of the application are more integrated and more effective in the classroom, and students were found to be highly interested in interacting with the system. With the application of augmented reality and the uncertainty caused by random probability, the effect of gamification was found to increase the desire to learn, and strengthened cognitive and observational powers which were helpful in describing the user's story.
