AbstractThis invention discloses apparatus and methods for monitoring the television viewing acts of individuals by transmitting a signal toward the individual and detecting the reflection of the signal from the individual's eyes to determine the time intervals and total times the individual is viewing the television. This viewing information is then correlated with the program information from the television. The apparatus and method of this invention can be used to identify each individual viewing the television and track and correlate the viewing information for each individual. The signals reflected from each individual's eyes can also be used to determine changes in blink rate and/or pupil dilation in order to determine the emotional response of each individual to the program being viewed. This invention also provides a system for monitoring the times at which particular programs are viewed by particular individuals even when the individual records the program on a VCR and views the program at a later time.
