1. A computing apparatus comprising: a storage unit; a network interface adapter to couple at least to the Internet; and a processor operatively connected to the storage unit and the network interface adapter, wherein the storage unit storing instructions that, when executed at least by the processor, cause the processor 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.
