The first part of this work summarizes the most accredited definitions of wellness, the related models, and the tools that can be found in the literature to assess quality of life. Then, it introduces three indicators that can be easily obtained from localization data to monitor some aspects of wellness. The advent of technology in this sector allows continuous and low-cost patient monitoring. This scenario applies particularly well in the context of health-care facilities, where doctors can thus concentrate on interpreting the data, resulting in a reduction in their workload.

For this reason, the scientific community is seeking new paradigms of care that provide compensatory interventions to the first signs of warning that can be detected in the behavior of the individuals. At this aim, this work proposes a method to detect the Activities of Daily Living carried out by a subject monitored at home through unobtrusive environmental sensors. The Activity Recognition system is composed of an unsupervised segmentation layer which splits the collected sensors activation data in time periods and a semantic layer that exploits a knowledge-based approach to provide the most probable activity label for each period. The system is enriched with a further layer to adapt the base knowledge according to the information directly provided by the resident.

Although the idea of creating an entirely risk-free society is impossible, it is feasible to monitor the health of elderly people by placing smart sensors in their houses, in order to react as soon as possible if a hazardous situation is taking place. In particular, this project focuses on the kitchen environment, by monitoring daily cooking activities and detecting anomalies in the use of the cooker, using some low-cost sensors: a Grid-EYE and a Sharp sensor.

Patients are provided with an iBeacon bracelet broadcasting data packets that are collected through the use of a dense network of devices acting as receiving antennas. The system evaluates the path-loss of the received signal and corrects the computed position with a probabilistic approach to avoid wall-crossing. Localization data are merged with information from other IoT devices such as smart sensors, appliances and expert annotations; the resulting dataset will be extremely important to analyze behaviors, habits and social interactions among patients.

In this paper we describe the application to collect data along the paths travelled by target people and show experimental results.

A need of particular significance is the identification of behavioral drifts. A relevant behavioral drift concerns sociality: older people tend to isolate themselves. There is therefore the need to find methodologies to identify if, when, and how long the person is in the company of other people (possibly, also considering the number). The challenge is to address this task in poorly sensorized apartments, with non-intrusive sensors that are typically wireless and can only provide local and simple information. The proposed method addresses technological issues, such as PIR (Passive InfraRed) blind times, topological issues, such as sensor interference due to the inability to separate detection areas, and algorithmic issues. The house is modeled as a graph to constrain transitions between adjacent rooms. Each room is associated with a set of values, fo...

In fact, the design of such kind of systems is heavily influenced by functional and non-functional requirements, and it is based on quite complex design flows. So, there is often the need to adopt a HW/SW co-design methodology able to support the designers during high-level phases so that they can perform early analysis before dealing with low-level ones. Such a methodology, to be effective, should consider also performance estimation and ESL HW/SW timing co-simulation. The goal of this paper is to introduce a novel and fast performance metric able to speed-up the early analysis and design space exploration to identify the more promising architectures for different application domains. In particular, the paper presents a framework to evaluate such a metric and to perform some preliminary analysis to evaluate its meaningfulness when exploited in the HW/SW domain.

These techniques are quite well established when working at a low abstraction level, whereas are currently under investigation when moving to higher abstraction levels, in order to cope with the increasing complexity of the systems being designed. This paper presents a model of soft error effects to be adopted ...

In this context, one of the most demanded feature is the possibility to promptly alert caregivers if an anomaly -e.g., a fall or a domestic accident - occurs. However, it is particularly difficult to monitor situations where the subject performs activities that do not involve motion (e.g., "sleeping", "watching TV"). In such cases, there is the need to understand whether the behavior of the person at home has a normal flow or if, for example, it is due to an illness that the monitoring system might not distinguish from other activities. In this work, we deepened the concept of home inactivity and we report a statistical survey study to identify the most relevant variables (observable set) that should be considered while designing an efficient AAL system.

Very often, in fact, the electrical performances of microwave networks strongly depend on the dimensions of parasitic elements, such as interconnection lines and net discontinuities. In this paper a new "constraint generation" CAD tool is presented. This program enables a quantitative analysis of the influence of parasitic dimensions on the final circuit performances and the singling out of most critical interconnections.

The aim of this paper is the definition of a design strategy for sequential circuits, starting from their description in terms of Finite State Machines. The attention is focused on a constant distance code and state encoding technique which provide, together with a traditional Berger encoding of the outputs, a self-checking system. Benchmark results and ...

It is composed of a set of modules for navigation, localization, planning, and autonomous wheelchair mobility, interfacing with the user. In this paper, we describe in detail the localization and navigation modules that can guide the target user to a selected destination and report our experience in a large care- and assistance-giving facility.

It relies on Hidden Markov Model to describe the behavior observing sensors data, while Likelihood Ratio Test gives the variation within different time periods.

However, researchers report a lack of high-quality publicly-available datasets: conducting experiments gathering such data is long and expensive, especially if the annotation of meaningful information (environment, person’s activity, health status) is required. Moreover, there are even more specific settings (e.g., dementia detection) where data must be related to a change in inhabitants’ behavior. We present a collection of new publicly-available datasets generated with the SHARON simulator. Thanks to this software, researchers can obtain synthetic data suiting their specific requirements. Two classes of datasets are described: one extends existing datasets preserving the original statistical properties, the other is composed of simulations of virtual i...

We present a non-invasive monitoring system to recognize if a person is seated using Bluetooth Low Energy technology. The system is composed by devices that can be easily attached to the furniture: a transmitter module that continuously broadcasts Bluetooth signal, and a receiver which collects the RSSi value of the received messages. Finally, a central server evaluates the attenuation of the Bluetooth signal within the 2.4GHz band, correlating it to the presence of a human body in the proximity of the device.
