摘要：The purpose of this paper was designing a fall detection algorithm as a solution so victims who are unable to move after accident could get help. Data were gathered by experimenting using accelerometer to find standby threshold and fall threshold. Data for standby threshold were processed by calculating all the differences and thus use the maximum difference for a threshold. Data for fall threshold were also processed by calculating all the differences and thus use the minimum difference from activities that were ended with a fall. Those thresholds were implemented into prototype application and tested again to find its accuracy. Results were 1 on sensitivity and 0.96 on specificity. It could be concluded that this fall detection algorithm has a 0.98 on its accuracy.
