Claim One:
1. A method for detecting motion, comprising: positioning a data acquisition system at a desired position and establishing a reference line based on the desired position of the data acquisition system; partitioning a field of view of the data acquisition system into an upper region and a lower region based on the reference line; acquiring motion information corresponding to a person in the field of view of the data acquisition system based on a plurality of pixels that experiences a change in a corresponding parameter; determining if the acquired motion information corresponds to the upper region, the lower region, or a combination thereof, in the field of view of the data acquisition system based on the plurality of pixels that experiences a change in a corresponding parameter; computing a duration of motion, a magnitude of motion and an area of motion of the person in the upper region, the lower region, or a combination thereof, based on the plurality of pixels that experiences a change in a corresponding parameter; and detecting a type of fall event corresponding to the person based on the computed duration of motion, the magnitude of motion and the computed area of motion of the person in the upper region, the lower region, or a combination thereof.
