Each year, about a third of people over 65y fall and about one out of five of these people suffer significant injury such as head trauma or fractures. Even those who are not injured, are often unable to get up on their own after a fall. This can result in them developing a fear of falling, loss of confidence to live independently, low physical acti... vity, poor social interaction, and even depression. Monitoring the movements of older people has become increasingly important but without compromising privacy and causing any sort of hindrance in day-to-day activities. Device-free sensing is a method that has been recently introduced to monitor the presence, location, motion, activity, and gestures of a person without the help of any attached device. This approach functions with wireless signals such as Wi-Fi and 3G/4G. Any movement done by the person present within the premises of the deployment area of the wireless network can be instantly gauged by the wireless signal patterns and characteristics. Moreover, Device free sensing works exceptionally well in smoky or dark conditions unlike other state-of-the-art sensing techniques, such as cameras and wearable sensors. This technique also prevents privacy intrusion. All these features make it a desirable option for pervasive sensing applications and warrants further study wrt fall detection.Read More
