1. A computing apparatus comprising: a storage unit; a network interface adapter to couple at least to the Internet; and a processing unit operatively connected to the storage unit and the network interface adapter, wherein the storage unit storing instructions that, when executed at least by the processing unit, cause the computing apparatus to: access data via an identity of a user, the data based on a first set of measurements produced by an imaging sensor sensing a first feature of the user, in a first session, regarding a first voluntary behavior of the user, the imaging sensor detached from the first feature when sensing the first feature, and the first set of measurements to include a plurality of images of the first feature of the user; access data based on a second set of measurements produced by the imaging sensor sensing a second feature of the user, in a second session, which is after the first session, regarding a second voluntary behavior of the user to interact with content presented by a display, the imaging sensor detached from the second feature when sensing the second feature, and the second set of measurements to include a plurality of images of the second feature of the user; analyze the data based on the first set of measurements and the data based on the second set of measurements, using at least a rule accessed via the Internet with the network interface adapter, to determine a first content to be presented to the user by the display; and access, using the network interface adapter, at least some of the first content via the Internet.
