Abstract: A virtual care system. The system identifies movement and status (e.g., location, time duration in a location, direction of movement, last activity) of an inhabitant of a premises, and takes actions based on the identified movement and status. The system includes an activity plan comprising a plurality of activity primitives. Each activity primitive comprises a time window, and classifies movements and/or activities of the inhabitant as, for example, expected or unexpected or abnormal patterns of behavior, based on occurrence and/or absence of output from a single sensor or paired sensors at the premises in the time window. The system is configured to notify caregivers with different levels of urgency (e.g., informational or warning to critical) based on the classifications of the detected movements and/or activities, and/or to take other actions such as turning off the lights and locking the door.
