Psychophysiological measures of human cognitive states applied in human computer interaction

Abstract

This paper reviews psychophysiological measures applied in Human Computer Interaction (HCI) by mainly focusing on studies related to human cognitive states. Although they have their own disadvantages, psychophysiological measures provide a promising way of user understanding to areas that seek “a sixth sense” for user psychological changes like HCI. We first briefly present the related literature and the major cognitive state assessment measurements. Then, fundamentals of psychophysiological measures are focused in-detail. We provide detailed information concerning their diagnosticity and sensitivity to human cognitive processes in table form. Finally, the paper discusses latest applications and point on the possible future directions.
