Some Psychological Responses Measured by a Commercial Electrooculography Sensor and Its Applicability

Students’ psychological responses were evaluated by a commercial electrooculography (EOG) sensor. As psychological responses, we picked up two factors – concentration power and the impression about the simplicity for problem solving. A glass-type EOG sensor detected the electrooculogram and calculated the blink rate (focus), the blink strength (calmness) and the head posture (posture), constituting the final parameter called concentration power. In this study, we investigated the correlation between the two psychological responses and EOG parameters. We could confirm the qualitative correlation between the EOG parameter corresponding to concentration power and the psychological response. At this point, we presume that it could be applied to e-learning in virtual classrooms soon. As for the impression about the simplicity to solve problems, we could not found the reasonable correlation. However, the detailed analyses for all of the parameters and their time-dependent behaviors might make it clearer and also other relations with more psychological response.
