The paradigmatic shift brought by the Internet of Things has already revolutionized many key sectors, like environmental monitoring, grid and energy management, manufacturing, and it can be seen as a promising solution to address challenging societal issues, like the ability to provide significant enhancement to quality of life for the elderly and, in general, people in need. As a consequence, Internet...
Systems for well-being and active aging increasingly rely on wireless technologies, as Bluetooth Low Energy (BLE), featuring low-power consumption. The wearable system presented in this paper consists of sensorized shoes connected via BLE to a smartphone. The peculiar streaming scenario, characterized by low throughput, but strict reliability requirements, has been modeled, and an experimental evaluation...
The concept of Internet of Things is being applied in several areas and involves a dramatically increasing number of market sectors. There is a large variety of commercial products, and the competition between different vendors often causes incompatibility among the available solutions. Due to the lack of a reference standard, in the highly fragmented arena of Ambient Assisted Living systems and Smart...
The adoption of the Internet of Things paradigm in Ambient Assisted Living platforms requires the investigation and analysis of issues related to data collection and processing. In fact, the peculiarities of Ambient Assisted Living services and applications pose specific requirements on the way data originated from sensors should be processed (locally or remotely), delivered (as raw data, or in aggregated...
For the people who are totally or partially unable to move or control their limbs and cannot rely on verbal communication, it is very important to obtain an interface capable of interpreting their limited voluntary movements, in order to allow communications with friends, relatives and care providers, or to send commands to a system. This paper presents a real time software application for disabled...
In the framework of Ambient Assisted Living solutions, it is very important to monitor the degree of vitality of elderly users in their daily activities, for example to evaluate if the user is spending too much time in a static condition, or not. In fact this could denote an anomalous trend, possibly related to cognitive or physical conditions worsening. For such a kind of monitoring to be effective,...
The paper presents a computer vision application, to enable message composition by head tracking. The application runs in real time on portable Android devices, exploits the available camera sensors, and accomplishes the device computational requirements. Satisfactory results in correct movements detection, and reliable composition of messages, are obtained by experiments.
