BRIGID (Behavioral Real-time Interaction Graphing for Infectious Diseases) is a locally hosted shipboard Real-Time Locating System (RTLS) platform that is designed to monitor and help mitigate disease spread among sailors on naval ships. The system uses Ultra-Wideband (UWB) wearable tags to continuously measure interactions between sailors, which includes distance between tags and duration spent at that distance. BRIGID visualizes live positions on a top-down floor plan, transforming raw data packets into digestible and actionable information, such as proximity heat maps and inter-person distance lines. The interface delivers a clean dashboard with tools like custom floor plan creation, tag and room profiling, calibration, and data analytics, allowing operators to quickly understand how to best respond to scenarios where a highly infectious disease is detected on board.
