Location, activity, and health compliance monitoring using multidimensional context analysis
A system and method for monitoring patient activity, location, present health status, and health protocol compliance. The present invention provides a more complete and accurate picture of a patient's health and safety context through a multi-dimensional user health and safety context analysis. Based on the combined computed health compliance score, calculated activity index, the computed location score, and calculated user health index, an overall user health and safety score is calculated. If the computed overall user health and safety score violates a predefined threshold or threshold range, an alert is transmitted to one or more persons.
