Automatic emotion response detection

An apparatus comprising:

• a computer system for determining a valence indication representing a human reaction to a particular area in a location, the computer system comprising:
• a processor unit;
• and
• computer-readable instructions stored on a computer-readable medium and configured to cause the processor unit to select a number of areas, a number of thresholds, a number of points, a number of emotion models, a number of expression models, a number of algorithms;
• use the number of areas, the number of thresholds, the number of points, the number of emotion models, the number of expression models, and the number of algorithms, to form a valence formula;
• retrieve a number of video streams from a number of cameras in the particular area in the location;
• use the number of video streams to calculate a valence indication for each of a number of individuals having images in the number of video streams;
• wherein the valence indication represents a predominant emotion of a number of individuals at a point in time in the particular area;
• and
• wherein the valence indication is calculated using the valence formula.
