This paper describes our approach to remove the effect of the Pupillary Light Reflex (PLR) component from pupil diameter signals obtained by an Eye-Gaze Tracking device (Eyetech Digital TM3) using the RGB camera from Kinect as a way to measure the illuminance around the eyes of the user. The purpose of this study is to obtain filtered pupil diameter signals that mainly contain the Pupillary Affective Response (PAR) used to estimate the arousal level in the response of a human subject to affective stimuli. The approach includes using the Adaptive Interference Canceller (AIC) technique to filter out the Pupillary Light Reflex (PLR) from pupil diameter signals (PD). We also present the empirical method followed to replace a stand-alone light meter with the RGB camera from Kinect to measure illuminance.
