Information in the form of emotional responses to a media presentation may be passively collected, for example by a microphone and/or a camera. This information may be tied to metadata at a time reference level in the media presentation and used to examine the content of the media presentation to assess a quality of, or user emotional response to, the content and/or to project the information onto a demographic. Passive collection of emotional responses may be used to add emotion as an element of speech or facial expression detection, to make use of such information, for example to judge the quality of content or to judge the nature of various individuals for future content that is to be provided to them or to those similarly situated demographically. Thus, the invention asks and answers such questions as: What makes people happy? What makes them laugh? What do they find interesting? Boring? Exciting?
