System and method for correlating audio and/or images presented to a user with facial characteristics and expressions of the user

摘要

A computer includes at least one processor and at least one computer readable storage medium accessible to the processor. The medium bears instructions executable by the processor to cause the processor to receive at least one image of at least one viewer of a display on which content is presented. The instructions also cause the processor to generate a signal representative of at least one expression of the viewer made at or around the time the content was presented based on the image of the viewer, and also to receive metadata identifying the content. The instructions then cause the processor to associate the metadata identifying the content with the at least one expression of the viewer.
