Smart Armband for Tracking Children Using a Mobile Application

Today, children are exposed to many dangers, so it is necessary to know their current location continuously. New technology allows connection to the internet almost anywhere, this can be used to track people through a remote device. Mobile apps have become popular with the help of ever-cheaper smartphones. This work develops a wearable device in the form of a smart armband for user tracking from a mobile location. The system is designed for use by children ages 5–12 in large areas with Internet coverage. Both stations are linked to a cloud database created in Firebase, this allows the exchange of information through the internet. In addition, the system allows the sending of audio notifications from the mobile application to notify the user at the remote site. Notifications are pre-stored on the electronic board for remote playback without overloading the network. In the testing stage, the children are monitored within a controlled area by tracking location and sending audio messages. The results show the functioning of the system, and the acceptance test applied is favorable for the characteristics of this proposal, although the audio notifications have the worst acceptance. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
