Patent ID: 8684742

Claim:
A method of determining a measure of response of an audience to a target stimulus comprising: providing a media device operable to expose each participant of the audience to a presentation, wherein the presentation includes a first series of standardized stimuli, at least one target stimulus, and a second series of standardized stimuli; providing a biometric sensor device operable to measure at least a first biometric parameter and a second biometric parameter; providing a visual attention device operable to collect visual attention data from each participant; providing a computer system operable to receive and record data representative of the at least two biometric parameters and the visual attention data; using the media device, exposing each participant of the audience to a presentation over a period of time, wherein each participant is exposed to a null exposure following exposure to each stimulus; and re-exposing each participant to the at least one target stimulus; using the computer system, receiving and recording data representative of the first and second biometric parameters and the visual attention data for each participant of the audience over the period of time of exposure; collecting and recording from each participant a response to at least one self-report question during the re-exposing step, wherein the at least one self-report question comprises a level of likeability of the at least one target stimulus, a valence of emotional response to the at least one target stimulus, an interest for the at least one target stimulus, or a combination thereof; calculating a single physiological score for each participant based on the data collected on the at least two biometric parameters; calculating an Emotional Impact Score for the audience using each participant's single physiological score; calculating an Explicit Emotion Score, wherein the Explicit Emotion score comprises a single score comprising a combination of the responses to each of the at least one self-report question; and plotting the Emotional Impact Score and the Explicit Emotion Score on a biphasic graph to predict a level of engagement of a population larger than the audience.
