  • 1. DEUS Deployment and Ease Use of wireless Services Scenario’s for future use: supporting senior mobility Main challenges Due to the greying society, cities and municipalities are studying and implementing new organizational care provision models in order to support independent living solutions for the elderly. Moving towards a residential intra-muros care setting is socially and economically the least preferred solution, although often inevitable and irreversible. Independent living support however involves more than providing adaptations to the house environment; it also includes aspects such as providing feelings of comfort and safety, the feeling of being surrounded at eventual times of need, the alleviation of social isolation and feelings of loneliness, the automated detection of potential harmful or dangerous situations, etc… Specific city areas providing augmented care levels are being depicted to offer a multiple of services to the inhabitants, depending on the evolving care needs, and still maintaining the natural character of city live with a mix of the population. Not only elderly but also citizens with specific needs (one-parent families, people with handicap, chronically ill) could benefit from these new concepts. The care dispatching function is then provided by a 24/7 call centre. The concept of these city+ services is shown on the inset.

  • 2. DEUS Deployment and Ease Use of wireless Services A mix of technological solutions already exists in order to support this model of social service provision, but interoperability and integration strategies are missing. In this way the optimum technological solutions is often not available and bric-a-brac solutions are used, resulting in unsatisfactory service levels to the multiple users (care providers, elderly, involved family and friends). Deus approach The specific use case studied by the DEUS project is the one of tracking and tracing of people based on location and identification of individuals, combined with an emergency call button. Although several solutions exist for partial support (GPS trackers on mobile phones for outdoor use, Personal Alarm Systems for indoor use), DEUS studied an integrated solution for the support of the senior who wants to stay mobile (in- and out- door) but needs augmented attention and follow-up. The DEUS approach is based on • A single and unique system for both in-door and out-door tracking and tracing of people • Identification of the elderly user, safeguarding his/her privacy • An emergency alarm button allowing voice communication (in- and outdoor) • A low-energy consumption technology for the wearable component in order to avoid repetitive battery re-charging • An easy handling technology with no or very limited user interface • An easy-to use, easy-to deploy technological solution for the care-providers in view of installation, operation and maintenance Deus solutions The DEUS project studied and developed following components in order to support the senior mobility use case. Architecture The inset illustrates the architecture that was developed in order to provide in- and outdoor location and tracking of people. The technology is based on sensor network solutions and DEUS developed a hybrid solution in order to offer the adequate precision needed for this use case. More technical detail is given in the sheet “positioning”.
  • 3. DEUS Deployment and Ease Use of wireless Services Architecture for location and tracking of persons Easy installation and operation For the use of the indoor and outdoor tracking and tracing of elderly people within an intra-muros care setting the DEUS planning tool can be used to design and install the optimum sensor node network configuration. It should be foreseen that all areas are covered were residential seniors can go, in- and around the building. For example the garden can be included in the layout, or a nearby green area where elderly tend to wander or walk with family-visitors. Easy layout and operation of sensor based positioning systems Tracking and tracing When assigning a unique “tag” to every residential elderly, the caregivers can track and trace the seniors without endangering their privacy. The information in view of linking the unique tag to a specific person is stored on the central server where the service is being installed. On the central portal, the caregiver can check at any time were a certain elderly inhabitant is. Individualised alerts can be generated and forwarded to portable devices.
  • 4. DEUS Deployment and Ease Use of wireless Services This can be very promising service in view of giving people with dementia and/or wandering behaviour still freedom to wander and walk throughout the premises of the residential settings (avoiding the need of code-closed doors). An automatic alarm system can be implemented in order to trigger alarms when a specific senior is wandering to far off or goes to potential unsafe places (e.g. direction of the street side). These alarms can be dispatched automatically to any preferred devices, or can trigger action warnings for the care providers. The profile of this automatic alarm triggering can be defined on an individual basis (based on the senior’s profile) or on specific contextual information (for e.g. when a senior is accompanied with a trusted visitor). Proof-of-concept realization Within the timeframe of the DEUS project a demonstrator set-up has been realized illustrating the use of wireless sensor network solutions for the tracking and tracing of people in an intra-mural care setting, covering a specific floor level and part of the surrounding garden. Small form factor wearable tags with energy harvesting solutions were not yet realized within the timeframe of the DEUS project.
