AI Guide Products System Based on Mental Model

In order to overcome the difficulties of visually impaired users to integrate into the society, and to meet the life needs of visually impaired users, this paper proposes a novel AI guide products system based on mental model. The system fully combines big data technology and artificial intelligence, and uses user analytic hierarchy process (AHP) to analyze user needs and build user psychological model. Based on this, the system can also give full play to the interaction of big data and artificial intelligence to obtain users' thinking mode and living habits, and then develop a series of exclusive services for users. The research results show that the system can develop the exclusive services according to the needs of each visually impaired user, and then meet the individual needs of visually impaired users to the maximum extent.
