What is it about?
Eyelids speak more eloquently than lips. Rapid serial blinks (RSB) can indicate temporally increased cognitive load with high temporal resolution. We proposed a method to create a personal criterion for respective participants by using empirical blink intervals. An increased number of the RSB detect participants who felt hard to understanding, indicating a poor understanding of the subject matter.

Why is it important?
The individual-based criteria proposed in this paper would be one of the resolutions for psychological phenomenon being problematic because of its large interindividual variability. Rapid serial blinks (RSB) in natural viewing settings can indicate temporally increased cognitive load with high temporal resolution and low calculation costs.
Perspectives
Spontaneous blinking is often unconscious to the experimental participants themselves, but speaks eloquently when viewed through observation by the experimenter. Rapid continuous blinking can be a perspective from which to objectively quantify the factors that impede viewers' understanding, not only in the classroom, but also in the behavior of all natural situations, such as films, TV commercials, online advertisements, etc.
