| Abstract: | In this report, we introduce an experimental method for eyeblink measurement by utilizing Doppler effect phenomena. In the cognitive science literature, eyeblink has been proposed as a complex phenomenon and acts as a representative of higher nervous processes. We developed an experimental setup in which the measurement of the eyeblink was conducted using a Doppler sensor accompanied by an accelerometer and an EOG (electrooculography) recording. From our experimental results, we found that the Doppler frequency related to blinking contains a dominant frequency at 2 Hz. Finally, we showed that when blinking is accompanied with head and body movements, eyeblink signal is separable by deploying the principal component analysis (PCA). |
