The leading cause of child death is unintentional injuries due to accidents. Currently, to prevent accidents, parents need to understand the injuries associated with each child's developmental stage, however, the way of precise grasping of the developmental stage is not yet established. The purpose of this study is to develop a system that automatically and directly estimates the developmental stage of children and indicates danger based on it. In this paper, as its basis, we propose a new technology that estimates the developmental stage in three steps: (1) Estimation of the developmental stage from children behavior observation, (2) recording of the numbers of the behavior occurrences, and (3) statistical analysis of behavior distributions. We demonstrated the feasibility of the proposed method to verify accuracy of behavior recognition, and investigate changes in behavior distribution with the development of children. The results showed that the behavior estimation had an accuracy of 89% and the behavior distribution changed clearly, indicating that the three-step estimation is useful.
