Optimization of an Accelerometer and Gyroscope-Based Fall Detection Algorithm

Figure 5

Display of Acc and for various activities: standing, running, sitting up, lying down, standing up, walking up steps, and falling. Also shown are the thresholds for , , and to determine a fall event. Lastly, events detected that satisfy each of the algorithm components are shown at the bottom. A fall event is denoted when all 3 thresholds are detected within the fall window.
