Re: [OTlist] Simulator sickness in VR driving

[Carmel_Tso]

Hello wendy,

Thanks for your reply. in our consent forms it has been stated that the subjects
may experience motion sickness. however during this early stages of the project
it has been found that 50 % of the subjects had c/o such discomfort. Do you have
any experience with using VR? you had signed  off working in  CDRS, i am curious
in what setting are you working in? does the D stand for driving and if you have
any experience with using a driving simulator?

Just to share with you, I had also spoken to someone who has experience with VR
and he says that the acceptable % of persons experiencing the motion sickness is
usually 8-10%. based on this reference, we have actually put our project on hold
for a time being and making some  adjustments  to our simulator.    Like you
have mentioned the visual input has a big effect. We are also having some
problems with the graphics that is slowing down frame rate. working with the
programmer ...  If you have any recommendations free feel to share with me...


Carmel

I don't think it's ethical to continue with the study unless you state in the
consent form that simulator sickness is a likely risk of participation in the
study.  As far as simulator sickness, it's quite common.  The prevalence is
higher in women and older adults.  There is too much discrepancy between the
information that the visual system is receiving and the lack of matching
vestibular input - this causes simulator sickness.  One does not have to get
motion
sickness to get simulator sickness.

Hope this helps.
