An involuntary action of opening and closing the eye is called blinking. In the proposed work, blink analysis has been performed on different persons performing various tasks. The experimental suite for this analysis is based on the eye gaze coordinate data obtained from commercial eye gaze tracker. The raw data is processed through a FSM(Finite State Machine) modeled to detect the opening and closing state of an eye. The blink rate of a person varies, while performing tasks like talking, resting and reading operations. The results indicate that a person tend to blink more while talking when compared to reading and resting. An important observation from analysis is that the person tends to blink more if he/she is stressed.
