Viewers of a multimedia program are monitored to detect responses. Time
data is stored with the responses and compared to responses from other
viewers at the same time in the multimedia program. A viewer type is
determined based on the responses. Further multimedia programs may be
offered to the viewer based on the viewer type. Transducers and sensors
placed within a viewing area may include, without limitation, audio
sensors, video sensors, motion sensors, subdermal sensors, and biometric
sensors.
