Abstract: Embodiments of a system to accurately record a viewer's emotion as he or she is watching or listening to media content are described. The system records physiological data from viewers and transmits it back to a central location as viewers watch, listen to, or otherwise interact with media such as TV, radio, video games, web sites or other media. An integrated physiological sensing device measures viewers' cognitive and emotional responses to media and transmits to a base station in close proximity to the sensing device. The physiological sensing base station can be integrated into home electronics devices such as digital video recorders, TV cable boxes, video cassette recorders, DVD players and gaming systems to record viewer's emotional and cognitive responses to the media and combining this response with context data from the electronics equipment to know what the viewer is responding to.

Abstract: Embodiments of a system to accurately record if viewers are actually watching, listening to, interacting with, or otherwise perceiving a television, computer monitor, or other media delivery device at any given moment are described. A detector circuit is coupled to the media delivery device and configured to receive a signal transmitted from an emitter placed on the body of a user positioned proximate the media delivery device. The detector receives a signal from the emitter when the user positions him or herself in a manner that indicates that the user is watching or otherwise paying attention to the media delivery device. An attention detector processor coupled to the detector circuit and configured to determine whether the user is perceiving content provided by the media deliver device.
