A personal emergency response system employs a structured terminology of body activities. Measurements of primary body activities using accelerometers, heart-bit monitors, etc. are converted to secondary and tertiary level body activities such as walk and fall, further sequenced and combined to determine a personal condition such as walk, stumble and fall, and to identify sequences of such conditions. The structured terminology enables a language supporting a functional description of body activities associated with physical and physiological measurements and enables a machine to understand physical activities. |
