Abstract: Methods and systems for tracking movements of participants in a market research study, for example, outside retail establishments, are provided. The methods and systems employ portable monitors carried on the persons of the participants to gather location data.

Abstract: The present invention concerns methods and systems for gathering data concerning usage of media data provided from a predetermined receiver to a user. First data concerning usage of the media data is gathered by means of a portable monitor carried on the person of the user. Second data concerning usage of media data by the predetermined receiver is gathered by a monitoring system separate from the portable monitor, the second data corresponding to at least a portion of the first data. Audience measurement data is produced based on the first and second data.

Abstract: Methods and systems for tracking movements of participants in a market research study, for example, within a commercial establishment, are provided. The methods and systems employ portable monitors carried on the persons of the participants to gather location data.

Abstract: Methods and systems for monitoring exposure of participants in market research to predetermined products, for example, within a commercial establishment, are provided. The methods and systems employ portable monitors carried on the persons of the participants to gather product exposure data.

Abstract: Systems, methods and devices for gathering data concerning exposure of predetermined survey participants to media displays are provided. A portable monitor is arranged to receive certain types of terrestrial-based signals, and in some specific cases, satellite-based signals, and to use such signals to generate location data indicative of a location of the portable monitor. The location data and stored media display data is analyzed to evaluate the survey participant's exposure to one or more media displays.
