The research on children's product design at home and abroad has undergone a long period of system construction and theoretical accumulation. In order to better promote the development of children's product design, it is now comprehensively sorted out and summarized. The CNKI database and the Web of Science core collection database are used as the sources of domestic and international data to analyze the general overview, hot topics and research trends of children's product design at home and abroad through Citespace, a visual literature analysis software developed by Dr. Chen Chaomei. The number of research literature on children's product design both at home and abroad shows an upward trend, gradually evolving from a single product to a complex system. While domestic research mainly focuses on user experience, emotionalization, child psychology, interaction design, and kansei engineering; while foreign research mainly focuses on inclusion, accessibility, participation, gamification and service design. The frontier trend of domestic research is more related to emotionalization and medical health and safety, while overseas research mainly focuses on gamification, medical health, developmental disabilities and literacy. In the future, children's product design should be more diversified in research content and strengthen interdisciplinary cooperation, put more focuses on special children groups in terms of research object, and combine quantitative and qualitative research methods in order to improve the theoretical knowledge system of children's product design.
