Localization System Supporting People with Cognitive Impairment and Their Caregivers

Localization systems are an important component of Active and Assisted Living (AAL) platforms supporting persons with cognitive impairments. The paper presents a positioning system being a part of the platform developed within the IONIS European project. The system’s main function is providing the platform with data on user mobility and localization, which would be used to analyze his/her behavior and detect dementia wandering symptoms. An additional function of the system is localization of items, which are frequently misplaced by dementia sufferers. The paper includes a brief description of system’sarchitecture, design of anchor nodes and tags and exchange of data between devices.both localization algorithms for user and item positioning are also presented. Exemplary results illustrating the system’s capabilities are also included.
