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.
