    摘要： Methods and apparatus to generate reference signatures are disclosed. An example method includes collecting a first signature for media being presented to a plurality of households; crediting the media when the first signature matches a reference signature in a reference signature database; in response to determining that the first signature does not match a reference signature in the reference signature database and the first signature does not match an unidentified signature in an unknown signature database, storing the first signature in the unknown signature database; in response to determining that a second signature does not match the reference signature in the reference signature database and the second signature matches the unidentified signature in the unknown signature database, and increasing a count associated with the unidentified signature.

    摘要： A method for presenting an object based on a biometric feature includes obtaining information about a first object that a user is gazing at, and biometric feature information of the user gazing at the first object; recognizing a satisfaction status for the obtained biometric feature information of the user gazing at the first object; and determining and presenting information about a second object based on the recognition of the satisfaction status for the biometric feature information of the user gazing at the first object.

    摘要： Example apparatus disclosed herein include means for processing media signatures of a first type to monitor media presented by a media device, the processing of the media signatures of the first type to be performed until a first media signature of the first type is determined to match a reference signature of the first type. Disclosed example apparatus also include means for processing media signatures of a second type associated with the first reference media to monitor the media presented by the media device, the processing of the media signatures of the second type to begin after the first media signature of the first type is determined to match the reference signature of the first type, the processing of the media signatures of the second type to end when a number of media signatures of the second type is determined not to match corresponding reference signatures of the second type.
