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...

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. Wendy Stav, PhD, OTR/L, CDRS *****************************
