Abstract:
Severe problems with out-of-home mobility are common under persons with cognitive impairment. Technical solutions such as geo-fencing systems, based on GNSS position monitoring, exist to mitigate wandering and getting lost of such patients. However, manually defined, fixed geo-zones effectively limit the freedom of the person and can lead to false alarms even during normal walking behaviour. This paper presents work in progress on a GNSS based position monitoring system that computes adaptive personalized safe zones from the user walking routine. The system implements semi-rigid zone borders allowing the user to explore new areas and automatically extend their personalized safe zones over time. Making use of routing services the system can generate temporary corridors for appointments outside of the users typical walking routine. While the technical implementation of the system is completed, it will be future work to evaluate the system's effect on users in a field trial and a clinic
al study.
