The paper aims to improve the interactive experience of children on rehabilitation products, and propose a user perception-oriented interactive experience evaluation method for children's home rehabilitation products. Based on the information processing process, the twelve senses theory of anthroposophy is introduced, and a user perception experience model is established; the measurement method combining questionnaire survey and eye tracking is used to obtain the psychological evaluation and physiological indicators of child users; the analytic hierarchy process is used to construct the product interaction experience evaluation system, and the entropy weight method is combined to give weights to various evaluation indicators and conduct a comprehensive ranking; based on BP neural network, a mapping relationship model between the characteristic elements of rehabilitation products and children's perceived experience preferences is established. Taking children's home rehabilitation foot pedal as an example, it is verified that the model has a good prediction effect. The scientific nature of the interactive experience evaluation system of children's rehabilitation products is improved by the method of combining subjective and objective. This method can effectively predict the perceived experience evaluation of children, and provide a reference for the interactive experience design and evaluation of such products.
