Generative AI has been increasingly explored across various domains, including education. However, its application in early childhood education (ECE) for assisting teachers’ administrative tasks remains limited. In this study, an embedded generative AI agent is developed and deployed on the Jetson Orin Nano platform, integrated with a touchscreen interface and an onboard camera for data input. Log generation is performed entirely on-device through simple user inputs and real-time image analysis, enabling automated creation of personalised child activity logs. The system’s effectiveness is evaluated in terms of accuracy and efficiency. In addition, data privacy concerns associated with collecting children’s behavioural data are addressed, offering insights into the practical deployment of embedded AI agents in ECE environments.
