The work aims to construct a multimodal embodied participation evaluation method for augmented reality research tourism products to deal with the singleness of the experience dimension when the body participates in the cognitive process, the limitations of the method for obtaining user interaction data, and the complexity of the evaluation of augmented reality research tourism products. Comprehensive literature research method and logical deduction method were used to discuss the evaluation method of embodied participation composed of two dimensions of user and environment. According to the image data, text data and psychological data generated in the interaction process, a "two-dimensional four-modal" systematic evaluation method of embodied participation and an evaluation index of multimodal data representation were constructed. The evaluation method could effectively evaluate the cognitive, behavioral and emotional participation modes and environmental guidance modes under different interactive tasks, and the complementarity and mutuality of different modal data could improve the comprehensiveness and accuracy of the evaluation of embodied participation. The "two-dimensional four-modal" systematic embodied participation evaluation method constructed in this study can provide a more scientific evaluation basis for product design and improvement, and promote the improvement of product design quality.
