Fall-Detection Algorithm Using 3-Axis Acceleration: Combination with Simple Threshold and Hidden Markov Model

Table 2

Best fall and ADL detection results evaluated by applying the parameter of the observation samples determined with fall events shown in Table 1 to the HMM algorithm shown in Algorithm  2 (sensitivity = 99.17% and specificity = 99.69% and accuracy = 95.89%).
