Abstract: A computer-implemented method assesses emotional responses of a panel of individuals to a user-defined event in a presentation. The method records video recordings of a presentation and a panel observing the presentation so that the video recordings may be synchronized with one another. The panel recording is processed to obtain emotional expression data for each face, in each frame, for the duration of the recording. A user may define the beginning and ending of an event in the presentation. The user may selected individuals of interest from the panel, as well as metrics regarding the emotional expressions. The method extracts emotional expression data meeting the requirements of user and displays the data.
