Oxygen therapy, administered from medical oxygen cylinders, can be used to relieve respiratory airways, and restore the supply of oxygen to the body’s vital organs. In this paper, we present a location-based ubiquitous crowdsourcing solution to enable COPD patients to request an emergency supply of oxygen cylinders. At the heart of the solution is a trusted platform that acts as a mediator for the ambient social interaction among a virtual and socially engaged community of requestors and suppliers. The geo-temporal data generated by this social interaction can be analyzed to uncover meaningful ambient environmental patterns. Our approach also uses image processing and computer vision techniques to help validate crowd responses. We discuss the details of the human-centric computer interaction design and its key features. We also elaborate on the challenges faced in the design and development of the solution and summarize the actions taken to address them.
