1. A machine-implemented method of detecting a presence or an absence of a human being, the machine-implemented method comprising:

  • aggregating a plurality of inputs, at least one of the plurality of inputs being from a human presence sensor for detecting the presence or the absence of the human being within a given proximity of a computing device;

    discarding a set of said plurality of inputs having a reliability less than a threshold value;

    obtaining corresponding estimated probabilities of the presence of the human being from the undiscarded inputs that indicate the presence of the human being;

    determining that the human being is present when any of the obtained estimated probabilities is greater than a predetermined value; and

    causing a computing device to behave in a predetermined manner when the determining determines that the human being is absent, whereinthe machine-implemented method is performed by the computing device.
