A system enables capturing biometric information while a user is perceiving a particular product, service, creative work or thing. For example, while movie-goers watch a movie, the
system can capture and recognize the facial expressions, vocal expressions and / or eye expressions (e.g., iris information) of one or more person's in the audience to determine an audience's reaction to movie content. Alternatively, the
system could be used to evaluate an audience's reaction to a public spokesman, e.g., political figure. The system could be useful to evaluate
consumer products or story-boards before substantial investment in movie development occurs. Because these biometric expressions (laughing,
crying, etc.) are generally universal, the system is generally independent of language and can be applied easily for global-use products and applications. The system can store the biometric information and / or results of any analysis of the biometric information as the generally true opinion of the particular product, service, creative work or thing, and can then enable other potential users of the product to review the information when evaluating the product.
