1. A position marker for conducting media consumption studies at study sites, comprising:

  • a receiver configured to receive a first signal from a personal measurement device and a second signal from a measurement device associated with a media device;

    a processor configured to measure a received signal strength of each of the first signal and the second signal; and

    a transmitter configured to transmit the measurements to a remote device, receipt of the measurements triggering the remote device to;

    identify, from a plurality of position markers, the position marker as a most proximate position marker to the personal measurement device, based on the measurements of the first signal performed by the position marker and measurements of the first signal performed by at least one other position marker of the plurality of position markers,estimate a displacement of the personal measurement device relative to the media device based on the measurements of the first signal and second signal performed by the position marker andidentify a panelist associated with the personal measurement device as consuming media from the media device, responsive to the estimated displacement being less than a threshold.
