Method and system for determining audience response to a sensory stimulus

A computerized system for determining measure of engagement of an audience for a presentation providing a sensory stimulus, the system comprising:

• a plurality of sensors, each adapted for measuring a biologically based response to the presentation over a period;
• the time period being divided into two or more time slots;
• a computer processing system adapted for receiving data relating to the presentation and data from the plurality of sensors providing a measure of at least one biologically based response to the presentation;
• an intensity processing module adapted for determining, for each time slot, at least one intensity value as a function of at least one of the measured biologically based responses;
• a synchrony processing module adapted for determining, for each time slot, at least one synchrony value as a function of at least one of the measured biologically based responses, wherein the synchrony value represents a number of audience members having the same or similar biologically based response for the at least one measured biologically based response;
• an engagement processing module adapted for determining, for each time slot, at least one engagement value as a function of said at least one intensity value and said at least one synchrony value;
• and
• a database of stored engagement values, wherein the at least one engagement value is compared to the stored engagement value to determine similarity.
