Reaching a good indoor geolocation without deploying extensive and expensive infrastructure is a challenge, because satellite positioning system is not available indoors. Geolocation could be of major use in healthcare facilities; to help care providers, visitors and patients to navigate, to improve movements and flows efficiency or to implement location-awareness systems. A system able to provide the location of a person in a hospital requires precision, multi-floors and obstacles management and should also perform in basements and outdoors. Such system needs also to be insensitive to environmental variations occurring in a hospital. These changes may be various kinds of obstacles. These can be the displacement of metallic objects, metallic machines, strong magnetic fields or simply human displacement. A system conforming to the above requirements can also answer various security questions, operational workflow management but also assist movement of people.

Information and communication technologies have a role to play in improving a citizen's quality of life. The ageing world population demonstrates the major challenge of assisting citizens in their various activities. ICTs could help them to have a healthier lifestyle, reduce physical efforts, reduce the risk of disease and prevent accidents or illnesses. PEACE aims to provide a system allowing the association of any type of sensors or data sources with any action within the user's environment. The generic approach of this system allows it to be deployed in several backgrounds. Indeed, multiple purposes can concern home automation, clinical environment automation and progress in the Ambient Assisted Living field. Creating this system required focusing on multiple areas like user interaction paradigms, I/O management, security management systems and automatic services discovery. Developing this project has demonstrated significant future job possibilities. Indeed, the implemented use-case is applicable to clinical environments and to domestic environments. Furthermore, this opens the door to enable the realisation of automation in the citizen's environment.

Sickle cell disease (SCD) is the most prevalent inherited blood disorder in the world. The symptoms decrease the quality of life of patients and can cause premature death. Self-help solutions for chronic patients are rising and increase the quality of life of patients. We are interested to identify the usefulness of eHealth tools for patients with SCD. We did a literature review to identify the main problems faced by patients and the existing eHealth solutions. The results show a low number of studies in the field but a multi-disciplinary interest. Positive health benefits for patients are reported as well as the need for more research. Patients and caregivers lack of education about the disease, healthy behaviors are unknown and clinical best practices underused. E-health tools can offer an appropriate support for the self-management of SCD by improving the quality of life of patients, by enhancing patient health literacy and by allowing clinicians to make better decisions.
