The SENZORG project aims to improve personalized care to elderly people using wireless sensor networks (WNS).
Humanitas, a health care provider in Rotterdam, is continuously looking for ways to optimalize the matching of health care demand and health care availability. The main issue in this process is to be able to recognize what kind of care has to be provided for in which situation. Accordingly, based on the previous information the most suitable service can be aligned for health care provision.
To support and facilitate the matching between health care demand and availability, Almende and Humanitas built a (wireless) sensor platform. This platform should increase the frequency of communication and monitoring in order to align the correct health care provider.
In collaboration with Humanitas, Almende identified a set of basic applications which can be developed using the sensor platform:
- Presence detection (e.g. in case of emergencies);
- Movement detection (e.g. in case someone has injured him/herself during a fall);
- Last-minute planning of care providers;
- Automatic administration of health care provision.
The most important challenge in SENZORG was to build a sensor network which is generic, easily capable of being reconfigured based on human or machine feedback. Problems that were tackled included ways to fuse the data from different kinds of sensors, maintaining the relevant temporal dynamics and introduce learning and conditioning in the sensor network, to create a dynamic filtering and escalation system that triggers reactions (e.g. from care providers) when necessary.
