Method and apparatus for detection and prediction of events based on changes in behavior

A computing machine for detecting and predicting an event based on changes in behavior of a person in an absence of information regarding the person's posture comprising:

• a computer memory;
• a sensor;
• and
• a computer processor;
• the computer processor executing a sequence of instructions stored in the computer memory, including instructions for:
• observing, using a sensor, a reading of a parameter of a body part of the person which is one of:
• horizontal location, vertical height, orientation, velocity, and time of observation, wherein the reading corresponds to less information than needed to define the person's posture;
• receiving the reading into a computer memory;
• determining from the received reading a pattern of behavior;
• detecting a change in behavior;
• identifying a combination of one or more readings corresponding to an abnormal event;
• and
• producing an alert signal when the combination of one or more readings corresponding to the abnormal event is identified.
