Abstract

Padovi predstavljaju problem starijoj populaciji koja je izložena navedenim događajima, a za posljedice mogu imati tjelesne ozljede, ali i posljedice uzrokovane učinkom dugog ležanja kao što su pothlađivanje, upala pluća, dehidracija i smrt. Ovom problemu pristupa se korištenjem senzorskog čvora Shimmer3 koji, između ostalog, sadrži i inercijalnu mjernu jedinicu pomoću čijih je signala moguće odrediti je li došlo do pada ili nije. Podatci koji se koriste su podatci s akclerometra koji se preko... More Bluetooth protokola šalju na računalo gdje slijedi daljnja obrada podataka. Cilj ovog rada bio je odrediti optimalni prag za provedbu algoritma kojim bi se što bolje registrirali padovi koji su se zaista dogodili i što više smanjila pojava lažnih alarma. Less

Abstract (english)

Falls are a major problem for the elderly people. The consequences can be physical injuries, but also from the long-lie effect, hypothermia, pneumonia, dehydration and death can occur. The solution for the above problem is to use sensor node Shimmer3 which, among other sensors, contains inertial measurement unit which signals can help to determine if fall occurred or not.The data which are used are the ones from the accelerometer which are sent over the Bluetooth protocol to the computer... More where further processing of data is accomplished. The main goal of this thesis is to determine optimal threshold for the algorithm implementation in purpose to improve the rate of detecting falls that actually had happened and to decrease the rate of false alarms.
