Abstract
A system and method for aggregating emotions of users for a media program. A server stores reference audio signal fingerprints, each associated with a reference audio signal of the program. For each user, the server computer: receives a first audio signal fingerprint from a client device operated by a user, the first audio signal fingerprint associated with a first audio signal comprising ambient sound associated with the user and an audio signal of the program; searches the stored reference audio signal fingerprints to determine one that is related to the first audio signal fingerprint; determines an ambient sound signal by obtaining a difference between the stored reference audio signal fingerprint and the first audio signal fingerprint; and determines, using the ambient sound signal, an emotion of the user for a program segment. The server computer aggregates the emotions to determine a representative emotion of the users for the segment.
