子どものリスク状態推測システムの提案

抄録

The authors have proposed a child monitoring system capable of estimating four risk conditions during a child’s outing-lingering in dangerous locations, deviating from designated school zones, abduction by vehicle, and immobility in arbitrary places—and notifying the guardian’s device of such conditions. The novelty of the proposed system lies in its foundation on the Crime Opportunity Theory and its ability to quantify the degree of danger at any given location. This enables more flexible condition assessment compared to conventional system. In an experiment conducted using a prototype within an actual school district, the simulated child device successfully inferred all four risk conditions and transmitted the corresponding notifications to the simulated guardian device.
