A multi-modal approach for activity classification and fall detection

"Special issue : Intelligent multisensory systems in support of information society"The society is changing towards a new paradigm in which an increasing number of old adults live alone. In parallel, the incidence of conditions that affect mobility and independence is also rising as a consequence of a longer life expectancy. In this paper, the specific problem of falls of old adults is addressed by devising a technological solution for monitoring these users. Video cameras, accelerometers and GPS sensors are combined in a multi-modal approach to monitor humans inside and outside the domestic environment. Machine learning techniques are used to detect falls and classify activities from accelerometer data. Video feeds and GPS are used to provide location inside and outside the domestic environment. It results in a monitoring solution that does not imply the confinement of the users to a closed environment.This work is funded by National Funds through the FCT-Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project PEst- OE/EEI/UI0752/2011.

Intelligent multisensory systems in support of information society

Nowadays, our environment is evolving more than ever in terms of connectivity and access to information, among others. People connected through social networks, such as Twitter or Facebook, upload photos, publish news about social events, etc. Many sensors that provide us with information about temperature, pollution, traffic congestion and energy consumption, among others, are being installed everywhere. Even our closest environment has greatly changed so that it now provides more information by means of motion sensors, surveillance cameras, etc. This is one of the results of the so-called information society becoming a reality
