Purpose This project aims to discuss how to use installation space and digital art to assist the self-healing of people with anxiety tendencies, and to alleviate the internal pressure and anxiety of the audience. The main research problem is to discuss a user-centered design perspective for the healing design of installation art Methods Based on the KANO-AHP theoretical model, the device products were put forward and applied to the design of art healing space. Firstly, KANO is used to classify the demand attributes of potential audiences. Secondly, AHP is used to construct the analytic hierarchy model of user needs, and the weight coefficients of each level are calculated, and the relatively important user needs are calculated from the sensory experience, interactive experience, and emotional experience of the audience, so as to obtain the design principles, and the design practice is carried out based on the results. Results The device space with a healing effect was designed by using KANO and AHP theoretical models. Conclusion According to the user evaluation results, the healing effect of the installation space is proved, which further verifies the scientificity of the design elements, and provides a reference for the installation art space to solve the problem of human mental health and well-being.
