The functional vision of the AALisabeth system is depicted by the following image:
The system entails the installation in the user’s house of a series of non-invasive intelligent objects that monitor the user’s lifestyle with the aim of preventing or diagnosing, at their onset, some of the most common medical conditions that afflict the elderly.
Different sensors carry out specific monitoring functions: presence of adequate light source in the environment; food-related tools (scale, table, plates fitted with RF-ID sensors to identify the food being served); opening of drawers and refrigerator, as well as cooking-stove ignition with recognition of user’s ID; an automatic pill dispenser that manages the prescription, dispensing the exact number of pills at the predefined time; a collection of clinical sensors to monitor primary physical parameters (weight, pressure, glucose level, etc); sensors to monitor physical activity (speed of movement, presence on chairs, beds and sofas); and, devices for the recording of outdoor activities with the possibility of sending an emergency signal and identification of the exact location of the event.
Furthermore, Meteda has leveraged its broad experience to design an easy-to-use nutrition monitoring device requiring the user only to fill out a diary (again using a tablet). The system is capable of automatically recognizing types of foods. After placing a plate on the scale, the tablet identifies and displays the applicable food category specifically assigned to that dish (for instance, pasta), and the user selects the specific food. The system then automatically produces a set of information relating to the food, including weight and bromatological composition.
In case of multiple users, each user will be required to wear a belt featuring Musa ID technology. To monitor outdoor activities, Meteda has developed Metalog, a portable GPS which allows the user to send a request for assistance from an identifiable location. The analysis conducted on data collected by the system yields significant lifestyle changes that may signal the onset of a medical condition.
