During the COVID-19 pandemic, the activities required for child physical development were reduced because classes were conducted remotely. Thus, an interactive edutainment content that can assist the physical and cognitive development of children in indoor environments is required. In this study, we designed an edutainment content production platform (ECPP) that allows teachers to design and produce an educational content using students’ movements. Teachers can develop an educational content by analyzing and modifying the children’s response to the designed edutainment content. The skeleton tracking of the human body using a depth sensor was used for the user interface and activity analysis. The proposed platform allows teachers to set images and movements for educational icons, as well as visual and sound effects that occur when a child touches the icons. The ECPP includes an activity control function that allows teachers to analyze the amounts of activity and movement, and then adjust the movement level in the edutainment content. In addition, a content management module allows teachers to store and share an interactive content.
