Abstract

The present invention is directed to a method and system for measuring the biologically based responses of an audience to a presentation that provides sensory stimulating experience and determining a measure of the level and pattern of engagement of that audience to the presentation. In particular, the invention is directed to a method and system for measuring one or more biologically based responses of one or more persons being exposed to the presentation in order to determine the moment-to-moment pattern and overall level of engagement. Further, the invention can be used to determine whether the presentation or the content in the presentation is more effective in a population relative to other presentations (or content) and other populations and to help identify elements of the presentation that contribute to the high level of engagement and the effectiveness and success of the presentation for that population.

Claims

1. A method of determining a measure of engagement of an audience for a presentation providing a sensory stimulus comprising:

exposing the audience to the presentation over a period of time, wherein said period of time is divided into two or more time slots;

for each member of said sample population, measuring a plurality of biologically based responses to said presentation;

for each time slot, determining at least one intensity value as a function of at least one of the measured biologically based responses,

for each time slot, determining at least one synchrony value as a function of a rate of change of at least one of the measured biologically based responses; and

for each time slot, determining at least one engagement value as a function of at least one of said intensity values and at least one synchrony value.

3. A method according to claim 1 wherein said biologically based responses are chosen from a group of responses including heart rate, skin conductance, respiration rate, respiration state, motion, and eye tracking

4. A method according to claim 1 wherein determining said at least one intensity value includes determining a standardized score as a function of at least one of a peak value, a trough value, a median value, an average value and a rate of change value of at least one of the biologically based responses.

5. A method according to claim 1 wherein determining said at least one synchrony value includes determining a variance of a rate of change value of at least one of the biologically based responses over at least a portion of the audience.

2. A method according to claim 2 further comprising:

comparing said at least one engagement value to an engagement value stored in a database corresponding to a second presentation; and

indicating that said presentation is similar to said second presentation based on the comparison.

6. 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 fordetermining, 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 fordetermining, for each time slot, at least one synchrony value as a function of at least one of the measured biologically based responses; and

an engagement processing module adapted fordetermining, 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.

7. A system according to claim 6 further comprising:

a comparison module adapted for comparing said at least one engagement value to an engagement value stored in a database corresponding to a second presentation; and

an indicator adapted for indicating that said presentation is similar to said second presentation based on the comparison.

8. A system according to claim 6 wherein said biologically based responses are chosen from a group of responses including heart rate, skin conductance, respiration rate, respiration state, motion, and eye tracking

9. A system according to claim 6 wherein said intensity processing module is adapted for determining the intensity value as a function of a standardized score and the standardized score is determined as a function of at least one of a peak value, a trough value, a median value, an average value and a rate of change value of at least one of the biologically based responses.

10. A system according to claim 6 wherein said synchrony processing module is adapted for determining the synchrony value as a function of a variance of a rate of change value of at least one of the biologically based responses over at least a portion of the audience.
