On the identification of the leading sensory cue in mulsemedia VR applications

This work aims to investigate the existence of a leading sensory cue in a mulsemedia Virtual Reality application involving three senses: vision, hearing, and touch. On the one hand this study can help in gaining insights into how the different senses contribute to mulsemedia applications in Virtual Reality. On the other, the identification of the leading cue could drive the optimization of Virtual Reality applications in terms of Quality of Experience, stimuli definition, and transmission requirements. In this paper, we present a mulsemedia experimental protocol for a subjective test aimed at identifying the material of a virtual object. We present the encountered challenges and describe and discuss the obtained results.
