摘要

Methods and apparatus to use scent to collect audience information are disclosed. An example apparatus includes a media meter to collect media identification information to identify media presented by an information presentation device; a people meter to identify a person in an audience of the information presentation device. The people meter includes a scent detector to detect a first scent of the person; a scent database containing a set of reference scents; a scent comparer to determine a first likelihood that the person corresponds to a first panelist identifier by comparing the first scent to at least some of the reference scents in the set; and identification logic to identify the person as corresponding to the first panelist identifier based on the first likelihood.
