SMART BEAR is a multinational European research project implementing an innovative, secure and privacy-preserving platform with market available wearable and medical devices, along with smart home sensors. The solution will target the elderly population who suffer from Hearing Loss, Cardio Vascular Diseases, Cognitive Impairments, Mental Health Issues and Balance Disorders. The platform will be tested and validated in five large scale pilots, in six different countries and 5100 individuals, providing evidenced-based interventions on lifestyle, medical significant risk factors, and chronic disease management. The present work demonstrates the initial requirements collection and analysis, along with the architecture and the Decision Support System, which will provide the evidence on the recommendations to the individuals.
