“…Postural instability is suggested to occur in novel environments in which "we fail to perceive the new dynamics or … are unable to … execute the control actions that are appropriate for the new dynamics" (Riccio & Stoffregen, 1991, p. 204); it lasts until the individual can adapt to the novel motion cues. As with sensory conflict hypothesis, potential limitations of the ecological hypothesis or related findings have been raised (Bos, 2011;Golding & Gresty, 2005;Lackner, 2014;Lubeck et al, 2015;Pettijohn et al, 2018).…”

Immersive technologies, such as virtual and augmented reality, initially failed to live up to expectations, but have improved greatly, with many new head-worn displays and associated applications being released over the past few years. Unfortunately, 'cybersickness' remains as a common user problem that must be overcome if mass adoption is to be realized. This article evaluates the state of research on this problem, identifies challenges that must be addressed, and formulates an updated cybersickness research and development (R&D) agenda. The new agenda recommends prioritizing creation of powerful, lightweight, and untethered head-worn displays, reduction of visual latencies, standardization of symptom and aftereffect measurement, development of improved countermeasures, and improved understanding of the magnitude of the problem and its implications for job performance. Some of these priorities are unresolved problems from the original agenda which should get increased attention now that immersive technologies are proliferating widely. If the resulting R&D agenda is carefully executed, it should render cybersickness a challenge of the past and accelerate mass adoption of immersive technologies to enhance training, performance, and recreation.

“…Immediately after VR exposure, a person will need to reintegrate the spatial characteristics of the real world to readapt. During this time, individuals typically experience aftereffects with hand-eye coordination [16], [17], visual perception [5], [22] and balance [23], [24]. Accordingly, both adaptation [17] and readaptation [16] are related to symptoms of VR sickness.…”

Beyond Feeling Sick: The Visual and Cognitive Aftereffects of Virtual Reality

et al. 2019

Despite continued improvements in virtual reality (VR) technologies, many people still experience adverse symptoms from using head-mounted displays (HMDs). Typically, these symptoms are monitored through self-report measures, such as the Simulator Sickness Questionnaire (SSQ); however, by only using subjective measures many symptoms may be overlooked. In an application-based study, we investigated visual and cognitive aftereffects of using HMDs and their relationship to the reporting of sickness on the SSQ. Visual (accommodation and vergence) and cognitive (reaction time and rapid visual processing) assessments were employed before and after participants engaged in a 30-minute VR table tennis game (VR group, n = 27) or went about their daily activities (control group, n = 28). The data showed changes in accommodation but no concurrent changes in vergence, which likely stems from decoupling accommodation and vergence in VR. Furthermore, larger changes in accommodation were linked to more severe sickness symptoms suggesting that decoupling accommodation and vergence could be more adverse than previously thought. The VR group also had slower decision (cognitive) times, but movement times were unaffected. These findings go beyond the typical self-reporting of sickness in VR studies. Moreover, we demonstrate that even in a high-quality commercial virtual environment, users may experience visual and cognitive aftereffects that may negatively influence their experience with subsequent activities in the real world. Developing an understanding of how VR aftereffects may influence later activities could help to minimise the risk of using HMDs for various applications and may be valuable to obtain a better understanding of user issues and VR safety.

Developing an understanding of how virtual reality (VR) aftereffects may influence later activities could help to minimise the risk of using head-mounted displays (HMDs) for various applications. This study investigated the visual and cognitive aftereffects of using HMDs and their relationship to the reporting of VR sickness symptoms. Visual (accommodation and vergence) and cognitive (reaction time and rapid visual processing) assessments were employed before and after participants engage in a 30-minute VR table tennis game (VR group, n = 27) or went about their daily activities (control group, n = 28). VR sickness symptoms were captured using the Simulator Sickness Questionnaire (SSQ). The data showed changes in accommodation but no concurrent changes in vergence, which likely stems from decoupling accommodation and vergence in VR. Furthermore, larger changes in accommodation were linked to a greater reporting of sickness symptoms suggesting that decoupling accommodation and vergence could be more adverse than previously thought. Participants in the VR group also showed slower decision (cognitive) times, but VR did not seem to affect their movement times in a five-choice reaction time task. The novel visual and cognitive findings from this study may be valuable to obtain a better understanding of the user issues and safety around VR usage.
