One thing I have found with haptics is that like VR, it can make you very sick. It has been shown that haptics can cause pretty nasty cases of vertigo[0]. In this study, after using a haptics device for 10 minutes the user started experiencing vertigo which lasted several hours, with mild symptoms persisting for several days.<p>I have noticed many of the same effects using the novint falcon haptic controller. It almost feels as if your hand is being pushed on when in fact it is not.<p>[0]<a href="https://www.ncbi.nlm.nih.gov/pubmed/14511456" rel="nofollow">https://www.ncbi.nlm.nih.gov/pubmed/14511456</a>
