Information from both sensors is used to characterize movements through selected features extracted from raw data. A classification system based on a Feedforward Backpropagation Neural Network is then trained, based on the extracted features. The performed tests present low false positives and low false negatives rates with good specificity and sensitivity values.engFall detectionNeural networkInertial sensorsFeatures selectionEmbedded devicesFall detection system for elderly peopleconference object
