Blink counts can differentiate between task type and load

Physiological measures have been increasing in popularity due to the growing availability of equipment that allows measurement in real time. Eye blinks are an easy measure to collect using video capture. Our findings indicate that blink counts effectively differentiate between taskloads and task types during a computer based task. Blink counts were significantly lower during the tasks involving high visual load when compared to non-visually demanding tasks. Lower numbers of blinks were observed under higher taskloads across all visual tasks.
