A method for identifying a motion of interest of an individual. The method includes collecting, at a computer, motion sensor input data of motions of the individual from a motion sensor for an interval of time. The method further includes analyzing, using the computer, the motion sensor input data using an analysis application having a set of classified predetermined motions of interest. The analysis application classifies a movement captured during the interval of time as a motion corresponding to one of a plurality of pre-determined motions of interest based on shared relative attributes. The method further includes generating an output providing notice of an identified predetermined motion of interest to a monitoring system.
