Systems and methods for associating media content with viewer expressions

A computer system, comprising:

• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• while a media content item is being presented to a user, capturing a momentary reaction of the user to a portion of the media content item;
• comparing the captured user reaction with one or more previously captured reactions of the user, wherein each previously captured reaction of the one or more previously captured reactions corresponds to a particular reaction type of a plurality of reaction types;
• identifying the user reaction as one of the plurality of reaction types based on the comparison;
• identifying the portion of the media content item corresponding to the momentary reaction of the user;
• and
• storing, at the computer system, a first association between the identified user reaction and the portion of the media content item.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a computer system with one or more processors, cause the computer system to:

• while a media content item is being presented to a user, capture a momentary reaction of the user to a portion of the media content item;
• compare the captured user reaction with one or more previously captured reactions of the user, wherein each previously captured reaction of the one or more previously captured reactions corresponds to a particular reaction type of a plurality of reaction types;
• identify the user reaction as one of the plurality of reaction types based on the comparison;
• identify the portion of the media content item corresponding to the momentary reaction of the user;
• and
• store, at the computer system, a first association between the identified user reaction and the portion of the media content item.
