This paper describes the development of the method to visualize hazardous area in living spaces regarding child head injury in falling. The method considered factors regarding both injury severity and frequency. The injury severity database was classified as the severity level of head injury in relation to falling height, the distance to the collision surface and the surface characteristics for head protection. The database was constructed based on both falling experiment using infant dummy and large amount of falling simulations using multi-body models for children. Moreover, a probabilistic model of climbing behavior, which assumes injury frequency, was constructed based on behavior measurement. Skull fracture possibility calculated from the database and the model was mapped on a 3D CAD model of a living environment. The method helps designers to easily prefind hazardous area in living spaces
