1. A method for monitoring activity and fall of a subject, comprising:
- measuring acceleration data using a human kinetic sensor (HKS) assembly placed at an upper trunk of the subjectsaid HKS assembly comprising a sensing unit configured for sensing a low G acceleration at a low frequency sampling range and a high G acceleration at a high frequency sampling range,said acceleration data being correlated to the spine of the subject due to a placement of the sensing unit at the upper trunk of the subject to yield behaviour indicators and threshold levels associated with characteristics the subject and an activity nature, state and level for a given environment and time;
processing the acceleration data in the low G acceleration into data reflecting a three-dimensional vectorial position of the upper body of the subject as being directly correlated with an orientation of the entire spine and body of the subject due to said placement of the HKS assembly at the upper trunk of the subject to yield a posture for a range of human activities in the given environment and time;
processing the acceleration data in the low G acceleration to;
recognize an activity of the subject,determine a phase, a state of the phase, levels of file activity over time, thresholds and controlled parameters range for the subject and the given environment and time,yield movement level, energy level and critical level threshold, andcontrol parameters range for the subject and the given environment and time; and
processing the acceleration data in the high G acceleration and low G acceleration into data identifying a fall event and determining the severity of the fall event based on at least one of said thresholds or said controlled parameters.
