Comprehensive understanding of infant behavior is required to prevent infant accidents in the home. We are developing a system to simulate infant behavior and accidents in virtual space to comprehensively understand infant behavior and accidents. We model infant grasping achievement in daily life, focusing on interaction with objects as a basic function of the infant behavior simulator we are developing. Grasping achievement refers to behavior in which an infant sees an object, approaches it, and grasps it. We classified elements related to infant behavior into developmental behavior, which is an internal factor, and environmental interest induction, which is an external factor. We created models by representing these factors in a stochastic form based on the knowledge on developmental behavior, which is known in the medicine field, and our new findings on environmental interest induction, which was obtained from infant observation. We integrated these models in a stochastic manner to create a grasping achievement model. We validated this model by comparing data on infant behavior with simulation results using the grasping achievement model.
