After acquiring all the above mentioned physiological (ANS) bio-signals in a VR environment, what are the steps to be done for correlating these bio signals with emotional level of the participant?
Also wanted to know how Sense of Presence can be determined through these bio-signals recorded in a VR scenario.
Any thoughts/ suggestions related to this will be helpful.
Thanks in Advance!!

Hi! Assessing emotional arousal is possible with EDA through peak detection, while heart rate variability could provide some useful information from PPG recordings. If these are compared against a control condition, then you should be able to see which is related to increased emotional arousal. Determining sense of presence can be done by simply asking participants (e.g. as in this article: Article Adding Immersive Virtual Reality to a Science Lab Simulation...
orArticle Gaming in Virtual Reality: What Changes in Terms of Usabilit...
), although it may be possible to corroborate that with biosensor data. The questionairres typically used are from here:Article Depth of Presence in Virtual Environments
or here:Article The Experience of Presence: Factor Analytic Insights
although others may exist as well). I've also written a bit about this in a blog post, in case that's of interest: https://imotions.com/blog/insights/research-insights/science-video-games/ I hope that helps!
