Electrodermal activity based study on the relationship between visual attention and eye blink

In this paper, the relationship between visual attention and eye blinking is described. In our experiment, we observed blinking when a subject performed a task. We determined that the subject´s visual attention functions during the task by electrodermal activity. Experimental results showed that blink rate decreased when the subject´s visual attention was engaged. On the other hand, blink rate increased when the subject´s visual attention shifted from attentive to inattentive. These findings enable a more objective evaluation of the relationship between visual attention and blinking when determining by electrodermal activity whether visual attention is engaged.
