Smart Bracelet: Empirical Multi-Purpose Bracelet GPS Tracker
Main Article Content
Abstract
This research aimed to develop and evaluate a smart multi-purpose GPS tracker bracelet designed to enhance user safety by enabling emergency location sharing and alerts through an SOS button with SMS functionality. The participants of the study were the researchers, who designed, assembled, and tested the prototype device within Iligan City, Philippines. An experimental research design was employed to assess the device’s detection range and response time for both calls and text messages. Data was collected through multiple field trials conducted at varying distances, and results were analyzed using descriptive statistics, including mean response times. Findings revealed that the device performed optimally in open spaces, with an effective detection range of up to 2.54 km and average response times of 12.3 seconds for calls and 13.6 seconds for texts. Although minor limitations were observed in coordinate detection speed, the smart bracelet demonstrated potential for improving child and student safety by providing parents and guardians with real-time location monitoring.
