Abstract: Background/Objectives: There has been a significant increase in the disappearance rate of children with disabilities. Hence, we propose a learning system to mitigate the issue of missing children with different levels of disabilities Methods/Statistical analysis: We have designed a preventive learning system which prevents children from being misunderstood. When a child enters an unsafe area, his smartphone notifies the user with a warning. In order to proactively characterize the learning and to deal with communication quickly, we compared the existing Bluetooth pairing function with a Bluetooth search function. Findings: The Bluetooth pairing function’s disadvantage is that the connection distance varies for each smartphone version and the built-in Bluetooth. To secure the notification distance and the stability of the notification distance, Bluetooth search was faster than the conventional Bluetooth pairing type. As a result, it was confirmed that the Bluetooth search function is shorter than the existing pairing function. This can enable the caregiver to respond faster by quickly recognizing that a child is missing. We applied the 35 second rule according to Kenneth Wooden’s study to a child’s stride, and conducted experiments to measure the distance that set off the notification using both Bluetooth pairing and search functions. Consequently, we were able to confirm that the Bluetooth search function notifies a child’s departure within 35 seconds, regardless of his/her pace. As a result of the existing three field tests, it is possible to prevent children from being harmed, even when children with a handicap is present with their guardian, and it is possible to track their position regardless of their distance from the inside or the outside of a room.
