Visualizing Accessibility-related Risk through Child Digital Human Model Posture Generation based on Kinematic and Mechanical Considerations

Abstract

This study develops a system to visualize accessible regions for childrens where accidents can occur in indoor environments using a posture estimation function of digital human models considering both kinematics and mechanics. For parents raising children, visualizing the potential hazards inside their own home can help them improve the environment to prevent inadvertent accidents. Our system simulates three-dimensional interaction of the children with the entities in the home environment using a digital human model that statistically reflects the physical characteristics of children. Reaching posture of the child digital human model that represents each age was estimated by solving inverse kinematics considering mechanical stability. Potential risk areas due to the reach of children were visualized by coloring the environmental model.
