Abstract
Editorial: Cybersickness in Virtual Reality and Augmented Reality
Highlights
Virtual reality (VR) systems introduced abnormal visual-vestibular integration and vergenceaccommodation, causing cybersickness (McCauley and Sharkey, 1992) reminiscent of simulator sickness reported by military pilots, e.g., having some shared causes and overlapping (Lawson, 2014a) but distinguishable symptoms (Stanney et al, 1997)
Head tracking, and graphics were expected to overcome cybersickness (Rheingold, 1991), yet it persists in today’s muchimproved virtual reality (VR) (Stanney et al, 2020a, 2020b). This must be resolved, because VR and Augmented Reality (AR)1 are proliferating for training for stressful tasks, exposure therapy for post-traumatic stress, remote assistance/control, and operational situation awareness (Hale and Stanney, 2014; Beidel et al, 2019; Stanney et al, 2020b, 2021; NATO Science and Technology Office, 2021)
Answering the key cybersickness questions requires controlled, labor-intensive research entailing: 1. Assessment of relevant stimulus experiences (Jasper et al.) and past susceptibility (Golding et al.): This is vital to interpretation and such measures can be used as covariates to improve analyses
Summary
Virtual reality (VR) systems introduced abnormal visual-vestibular integration and vergenceaccommodation, causing cybersickness (McCauley and Sharkey, 1992) reminiscent of simulator sickness reported by military pilots, e.g., having some shared causes and overlapping (Lawson, 2014a) but distinguishable symptoms (Stanney et al, 1997). 3) Cao et al provided VR users with Earth-stable granulated peripheral cues that allowed some peripheral vision, which improved visual target searching better than restricting field-of-view (FOV), a typical countermeasure. Could this approach mitigate cybersickness better than FOV restriction?. 6) Kim et al posited that linear head oscillations increase sensory conflict in VR devices that only track angular motion While they failed to detect device-related differences in perceived scene stability, spatial presence, or cybersickness, this was a creative pilot study exploring implications of different tracking devices. They did not detect a relationship between sickness and vection, adding to the
