MODELING GRASPING ACHIEVEMENT BEHAVIOR OF INFANT BASED ON DEVELOPMENTAL BEHAVIOR MODEL AND ENVIRONMENTAL INTEREST INDUCTION MODEL

摘要

To prevent infant unintentional accident at home, it is necessary to understanding infant behavior comprehensively. The authors are developing a system for simulating infant behavior and accident in virtual environment by modeling infant developmental behavior and infant surrounding environment. In this paper, we focused on a function of interaction with physical objects as one of basic functions which the infant behavior simulator has, and modeled grasping achievement behavior which infant takes in daily environment. Infant grasping achievement behavior means a sequence of behavior that infant is interested in a certain object, moves to it and grasps it. The determinant factors related to infant behavior are classified into developmental behavior as an internal factor and interest induction of environment as an external factor. The authors created the grasping achievement behavior model by integrating these models probabilistically. The performance evaluation of the infant grasping achievement behavior model is conducted by comparing the output of the simulator and the data measured in the infant observation room.
