Physiological Synchrony: A Novel Approach to Evaluating User Quality of Experience in Collaborative Distributed Virtual Reality Environments

Synchrony at the physiological level provides an objective measure that can be utilized to examine the
collaboration between collaborating partners. When individuals collaborate on a task, their physiological
signals can provide valuable insights into their cognitive states, emotions, and overall engagement levels. By
analyzing and interpreting these signals synchrony, it becomes possible to gain a deeper understanding of
the users’ experiences and optimize the collaborative environment accordingly. In our proposed VR system,
synchrony from the physiological data of individuals is used to infer the user Quality of Experience (QoE)
of collaborators. We propose Physiological Synchrony (PS) of physiological signals as a new method to
investigate QoE in a collaborative distributed Virtual Reality immersive environment. We investigate the
potential effects of the proposed VR system to support synchrony during remote collaboration, as well as
the design guidelines for building such systems
