Localization System Supporting People with Cognitive Impairment and Their Caregivers

Jerzy Kolakowski, Vitomir Djaja-Josko, Marcin Kolakowski, Jacek Cichocki


Localization systems are an important component
of Ambient and Assisted Living 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
The paper includes a brief description of system’s architecture,
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.
