Jeremy Cowles raised question around whether there is a “direct link or quote” where can contract epilepsy from VR.
Right now, in official guides and due to the lack of studies / mainstream users only the standard guidance based on existing media applies (e.g. 1 in 4000 could contract, typically younger people etc) — see Oculus Health and Safety p2 https://static.oculus.com/documents/health-and-safety-warnings.pdf
Unfortunately, early anecdotal evidence would suggest that this proportion could be higher due to the intensity of VR as a trigger.
Again, this is not positioning as a scientific claim but is something that needs to be further explored.
