A Physiological Approach of Presence and VR Sickness in Simulated Teleoperated Social Tasks
David Achanccaray, Hidenobu Sumioka · 2023
The presence (or telepresence) feeling and virtual reality (VR) sickness affect the task execution in teleoperation. Most teleoperation works have assessed these concepts using objective (physiological signals) and subjective (questionnaires) measurements. However, these works did not include social tasks. To the best of our knowledge, there was no physiological approach in teleoperation of social tasks. We measured presence and VR sickness in a simulation of teleoperated social tasks by questionnaires and analyzed the correlation between their scores and multimodal biomarkers. The results showed some different correlations from the findings of non-teleoperation studies. These correlations were between presence and neural biomarkers in the frontal-central and central regions (for the beta and delta bands) and between VR sickness and brain biomarkers in the occipital region (for the alpha and beta bands) and the mean temperature. This work revealed significant correlations to support some biomarkers as predictors of the trend of presence and VR sickness in simulated teleoperated social tasks. These biomarkers might also be valid to predict the trend of telepresence and motion sickness in teleoperated social tasks in a remote environment.
