TIME OUT-OF-HOME MONITORING

摘要

Systems and methods for determining time a subject spends outside of their home based on signals received from unobtrusive sensors in the home are disclosed. In one example approach, a method for determining time a subject spends outside of their home comprises receiving sensor firing data for a duration from sensors in the home, dividing the duration into epochs, extracting features from the sensor firing data received during the epoch, and classifying each epoch as out-of-home or in-home based on the features extracted from the sensor firing data during the epoch.

1. A computer-implemented method for determining time a subject spends outside of their home, comprising:
receiving sensor firing data for a duration from sensors in the home, the sensors comprising an exterior door sensor and room motion sensors; dividing the duration into epochs; for each epoch, extracting features from the sensor firing data received during the epoch, wherein extracting features from the sensor firing data received during the epoch comprises:
calculating a number of sensor firings during the epoch;detecting whether the subject was in or out of a bed during the epoch based on sensor firing data from room motion sensors;in response to the exterior door sensor being the last sensor fired during the epoch, indicating a leaving event during the epoch;in response to the exterior door sensor being the first sensor fired during the epoch, indicating an arrival event during the epoch;identifying whether or not the last motion sensor fired during the epoch occurred in a room of the home from which the subject could directly leave the home; and classifying, using a classifier, each epoch as out-of-home or in-home based on the features extracted from the sensor firing data during the epoch.
