Applying the Trajectories Conceptual Framework: A Case Study of an IoT Health Data Monitoring Application.

We present a case study on the design and development of an IoT application, called Real-time Emergency Communication System for HAZMAT Incidents (REaCH). The REaCH application utilizes the latest IoT technologies to capture and monitor individual health data (heart rate, ECG, heat index) and provides an interactive dashboard to assist incident commanders to evaluate if a firefighter needs to be removed from the scene due to a potential threat to their health and well-being. In our study we examined the design and development of a dashboard utilizing the Trajectories Conceptual Framework (TCF) and Action Research (AR). The aim of this paper is to analyze if TCF can guide the development of a dashboard from research to industry. Our study consists of four cycles that span from the requirement gathering phase to delivering a minimal viable product. We conclude that the integration of TCF and AR provides a solid approach to evaluate the design and develop a real-time health monitoring IoT dashboard. We also propose the addition of a Developer Trajectory to address the technical aspects and help guide both the front-end and back-end developers through the various stages of the applications development using IoT technology.
