The present work focuses on the search for an alternative method to current QOE methods for multimedia applications in the context of viewing and listening to 2D or 3D AV content. The proposed approach approaches QOE from the angle of joint analysis of ocular indicators and physiological indicators (electrodermal activity, heart rate, peripheral skin temperature, peripheral blood volume) and ocular indicators (PERCLOS, eye blink duration and frequency, number of saccades, pupillary diameter). Physiological and ocular measurements have the advantage of not being subject to the biases of subjective measures (representativeness, scales, etc.) and to reflect phenomena such as fatigue or mental effort, potentially induced by the presence of degradations on audio and/or video signals and which may be critical from a QOE point of view. Two protocols were tested.
