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; an attachment mechanism coupled to the housing to secure the housing to a person; and a sensor to detect a status of the attachment mechanism to enable determination of whether the device is being carried by the person.
Claims25
A portable audience measurement device, comprising:
- a housing;
- a media detector in the housing to collect media exposure data;
- an attachment mechanism coupled to the housing to secure the housing to a person;
- and
- a sensor to detect a status of the attachment mechanism to enable determination of whether the device is being carried by the person.
A method of detecting wearing of a portable audience measurement device, comprising:
- determining whether an attachment mechanism is in a position indicative of the device being worn by a person;
- calculating a frequency of indications that the device is being worn by the person for a period of time;
- and
- calculating a likelihood that the device is being worn by the person based on the frequency.
A method of crediting audience measurement data, comprising:
- collecting audience measurement data with a portable device;
- sensing a first position of an attachment mechanism of the portable device using a primary sensor;
- calculating a likelihood that the attachment mechanism is attached to an object based on information related to the first position of the attachment mechanism;
- sensing a second position of the attachment mechanism using a secondary sensor;
- adjusting the likelihood that the attachment mechanism is attached to the object based on the second position of the attachment mechanism;
- and
- invalidating the audience measurement data for a time period the likelihood for the time period is below a threshold.
