Human presence detection

A computing device comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor;
• at least one item from a group consisting of a memory and a combination of the memory and at least one hardware logic component, the at least one item being configured to cause the computing device to:
• aggregate a plurality of inputs, at least one first input of the plurality of inputs being from a human presence sensor for detecting a presence of a human being within a given proximity of the computing device, and at least one second input of the plurality of inputs being from a short-range wireless transceiver in the possession of the human being;
• obtain corresponding estimated probabilities of the presence of the human being from the plurality of inputs;
• determine whether the human being is present or absent, wherein the computing device determines that the human being is present when any of the obtained estimated probabilities is greater than a predetermined value;
• and
• cause the computing device to perform a first one or more actions when the human being is determined to be present or a second one or more actions when the human being is determined to be absent.

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 first input 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, and at least one second input of the plurality of inputs being from a short-range wireless transceiver in, the possession of the human being;
• obtaining corresponding estimated probabilities of the presence of the human being with respect to each of the plurality of 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, wherein the reliability of at least some of the plurality of inputs deteriorates over a predetermined time period after detection of the human being;
• and
• causing a computing device to behave in a predetermined manner when the determining determines that the human being is absent, wherein
• the machine-implemented method is performed by the computing device.
