A novel ultra-wideband radar sensor system for simultaneous detection of falls and vital signs is presented. The suggested system is able to deal with real-life conditions, such as lack of real-fall data for training, body movements, several people present, and privacy issues. Micro-Doppler features, extracted from time-frequency spectrograms, are used to classify human actions as related to normal...
Currently available technological solutions do not allow to reliably detect falls in the elderly, due to still-open issues on both sensing and processing sides. In fact, the most promising sensing approaches raise concerns for privacy issues (e.g., visionbased approaches) or low acceptability rate (e.g., wearablebased approaches); whereas on the processing side, commonly used methodologies are based...
In recent years several world-wide ambient assisted living (AAL) programs have been activated in order to improve the quality of life of older people, and to strengthen the industrial base through the use of information and communication technologies. An important issue is extending the time that older people can live in their home environment, by increasing their autonomy and helping them to carry...
