Abstract
A method and system for fall detection of a user are disclosed. In a first aspect, the method comprises determining whether first or second magnitude thresholds are satisfied. If the first or second magnitude thresholds are satisfied, the method includes determining whether an acceleration vector of the user is at a predetermined angle to a calibration vector or whether the user is at a stooped posture. If the acceleration vector of the user is at the predetermined angle to the calibration vector or if the user is at the stooped posture, the method includes determining whether an activity metric is satisfied.
