ABSTRACT:
Methods and apparatus to detect carrying of a portable audience measurement device are disclosed herein. An example portable audience measurement device includes a housing; a media detector in the housing to collect media exposure data; a first status sensor to detect a first distance between the housing and an object at a first time, wherein the first status sensor is to detect a second distance between the housing and the object at a second time; and a distance comparator to generate a first signal indicative of a relationship between the first distance and the second distance to enable determination of whether the device is being carried by a person.
