PlayMeBack - Cognitive Load Measurement using Different Physiological Cues in a VR Game

Abstract

We present a Virtual Reality (VR) game, PlayMeBack, to investigate cognitive load measurement in interactive VR environments using pupil dilation, Galvanic Skin Response (GSR), Electroencephalogram (EEG) and Heart Rate (HR). The user is shown different patterns of tiles lighting up and is asked to replay the pattern back pressing the tiles in the same sequence they lit up. The task difficulty depends on the length of the observed pattern (3-6 keys). This task is designed to explore the effect of cognitive load on physiological cues, and if pupil dilation, EEG, GSR and HR can be used as measures of cognitive load.
