Abstract

Technique for providing an indication of viewer interest in response to visual stimuli. A viewer is exposed to visual stimuli. The viewer'"'"'s saccadic eye motion occurring while the viewer is being exposed to the visual stimuli are measured. The visual stimuli are displayed together with the measured saccadic eye motion that occurred while the viewer was being exposed to the visual stimuli as an indication of the viewer'"'"'s interest in such visual stimuli.

Claims

1. A method of providing and indication of viewer interest in response to visual stimuli, comprising:

exposing a viewer to visual stimuli;

monitoring saccadic eye motion of the viewer occurring while the viewer is being exposed to the visual stimuli; and

displaying the visual stimuli together with the monitored saccadic eye motion that occurred while the viewer was being exposed to the visual stimuli as an indication of the viewer'"'"'s interest in such visual stimuli.

2. The method of claim 1, wherein the step of monitoring saccadic eye motion of the viewer comprises measuring microsaccadic eye motion.

3. The method of claim 1, wherein the step of monitoring saccadic eye motion comprises measuring the number of saccadic eye movements occurring during a designated period of time.

4. The method of claim 3, wherein the number of saccadic eye movements occurring during a designated period of time is a number of oscillations per second.

5. The method of claim 4, wherein a higher number of oscillations per second is displayed as an indication of a higher level of viewer interest.

6. The method of claim 4, further comprising the step of:

obtaining a reading of the number of oscillations that occur during the predetermined time period; and

converting the readings into data suitable for display.

7. The method of claim 6, wherein the reading is converted into a number superimposed on a program being reproduced on a display.

8. The method of claim 6, wherein the reading is converted into a bar graph superimposed on a program being reproduced on a display.

9. The method of claim 8, wherein the bar graph includes a current reading and at least one previous reading to provide an indication of a trend.

10. The method of claim 6, wherein the reading of the number of oscillations comprises an average of the saccadic eye motion of a plurality of viewers reacting to the visual stimuli.

11. The method of claim 3, wherein the displaying step displays the visual stimuli together with an average of the saccadic eye movements of a plurality of viewers reacting to the same visual stimuli.

12. The method of claim 1, wherein the visual stimuli are from a commercial or a performance that is being broadcast by a television network.

13. The method of claim 1, further comprising the steps of:

storing in a memory data corresponding to a program signal used for generating the visual stimuli to which the viewer was exposed;

storing in the memory data corresponding to the measured saccadic eye motion of the viewer occurring while the viewer was being exposed to the visual stimuli; and

retrieving from the memory program signal data corresponding to visual stimuli and, in association therewith for simultaneous display, data corresponding to the measured saccadic eye motion of the viewer that occurred while the viewer was being exposed to the visual stimuli related to the retrieved program signal data.

14. Apparatus for providing an indication of viewer interest in response to visual stimuli, comprising:

means for exposing a viewer to visual stimuli;

means for monitoring saccadic eye motion of the viewer occurring while the viewer is being exposed to the visual stimuli; and

means for displaying the visual stimuli together with the monitored saccadic eye motion that occurred while the viewer was being exposed to the visual stimuli as an indication of the viewer'"'"'s interest in such visual stimuli.

15. The apparatus of claim 14, wherein the means for monitoring saccadic eye motion of the viewer comprises means for measuring microsaccadic eye motion.

16. The apparatus of claim 14, wherein the means for monitoring saccadic eye motion comprises means for measuring the number of saccadic eye movements occurring during a designated period of time.

17. The apparatus of claim 16, wherein the number of saccadic eye movements occurring during a designated period of time is a number of oscillations per second.

18. The apparatus of claim 17, wherein a higher number of oscillations per second is displayed as an indication of a higher level of viewer interest.

19. The apparatus of claim 17, further comprising:

means for obtaining a reading of the number of oscillations that occur during the predetermined time period; and

means for converting the readings into data suitable for display.

20. The apparatus of claim 19, wherein the means for converting converts the readings into a number superimposed on a program being reproduced on the means for displaying.

21. The apparatus of claim 19, wherein the means for converting converts the readings into a bar graph superimposed on a program being reproduced on the means for displaying.

22. The apparatus of claim 21, wherein the bar graph includes a current reading and at least one previous reading to provide an indication of a trend.

23. The apparatus of claim 19, wherein the means for obtaining a reading of the number of oscillations comprises means for obtaining an average of the saccadic eye motion of a plurality of viewers reacting to the visual stimuli.

24. The apparatus of claim 16, wherein the means for displaying displays the visual stimuli together with an average of the saccadic eye movements of a plurality of viewers reacting to the same visual stimuli.

25. The apparatus of claim 14, wherein the visual stimuli are from a commercial or a performance that is being broadcast by a television network.

26. The apparatus of claim 14, further comprising:

means for storing in a memory data corresponding to a program signal used for generating the visual stimuli to which the viewer was exposed;

means for storing in the memory data corresponding to the measured saccadic eye motion of the viewer occurring while the viewer was being exposed to the visual stimuli; and

means for retrieving from the memory program signal data corresponding to visual stimuli and, in association therewith for simultaneous display, data corresponding to the measured saccadic eye motion of the viewer that occurred while the viewer was being exposed to the visual stimuli related to the retrieved program signal data.
