15. 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. 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. - View Dependent Claims (24, 25)
