“…That is, relations between body segments and body axes influenced the orthogonal variables of positional variability and movement multifractality. A similar effect was reported by Walter et al (2019) who exposed standing participants to oscillation of the visual environment along the line of sight.…”

Motion sickness is common in virtual environments. The risk of motion sickness varies widely between individuals and across situations. The subjective experience of motion sickness often is preceded by distinctive patterns of movement in the control of head and body posture. Previous research has documented reliable sex differences in the kinematics of postural activity, as well as reliable differences in postural activity between participants who were in control of a virtual vehicle and participants who were not. We asked whether postural precursors of motion sickness would simultaneously be influenced by individual and situational factors. We analyzed movement of the head and torso while seated participants were exposed to a driving video game presented through a head-mounted display. Half of the participants were women, and half were men. Using a yoked-control design, half of the participants controlled the virtual vehicle (Drivers), whereas half watched previously recorded vehicle trajectories (Passengers). The maximum exposure duration was 15 min, but participants were instructed to discontinue participation immediately if they experienced any symptoms of motion sickness, however mild. We analyzed movement kinematics not only in terms of sex and vehicle control but also in terms of participants who did or did not report motion sickness. Movement differed between Drivers and Passengers, in terms of both the spatial magnitude and multifractality of movement. The spatial magnitude of movement was simultaneously influenced by sex (men vs. women) and vehicle control (Drivers vs. Passengers). In addition, in statistically significant interactions, we identified postural precursors of motion sickness that differed between Drivers and Passengers and, separately, between Drivers and Passengers as a function of sex. The results are consistent with a prediction of the postural instability theory of motion sickness etiology and shed new light on the multifactorial origins of postural precursors of motion sickness in virtual environments.

“…Although there is a rich literature on the use of predictive models for cybersickness (Kim et al, 2005;Dennison et al, 2016;Weech et al, 2018b;Walter et al, 2019), the current results contribute to a previously sparse literature on the link between sensory re-weighting and cybersickness. One previous study examined the relationship between self-reported carsickness and the time course of habituation to galvanic vestibular stimulation (GVS) during balance control (Balter et al, 2004).…”

Sensory dynamics can be reshaped by environmental interaction, allowing adaptation to altered or unfamiliar conditions that would otherwise provoke challenges for the central nervous system. One such condition occurs in virtual reality, where sensory conflict is thought to induce cybersickness. Although the sensory re-weighting process is likely to underlie adaptation to cybersickness, evidence of a link between sensory re-weighting dynamics and cybersickness is rare. Here, we characterize the relationship between sensory re-weighting in a balance control task and cybersickness. Participants were exposed to visual oscillation while standing in tandem stance. The sway path length of the center of pressure (COP) was measured and averaged for each level of visual oscillation, and a ratio was computed between high and low oscillation magnitudes to reflect the relative contributions of multiple sensory sources of information concerning balance control. Results showed a significant relationship between the magnitude dependency of sway and common sub-scales of cybersickness: disorientation [r (21) = 0.45, p = 0.028] and oculomotor discomfort [r (21) = 0.45, p = 0.033]. We conclude that participants who reported less cybersickness were better-able to down-weight visual information at high magnitude oscillations, thus demonstrating a lower dependency between sway and visual magnitude. The results confirm the utility of balance control as an indicator of cybersickness, and support the role of multisensory re-weighting in determining an individual's tolerance to VR applications.

Immersive Environment for Occupational Therapy: Pilot Study

There has been increasing interest in the application of virtual reality (VR) to occupational therapy and rehabilitation fields. This work presents a VR-based city adventure framework designed for occupational therapy. Its concept is based on taking the user to travel around a virtual city, where the motion is powered by the execution of some type of physical exercise, namely cycling in the current example. This framework is extensible and may integrate different goals focused on improving/maintaining motor and cognitive skills necessary for daily activities, mainly through upper and lower limb exercises and mental challenges. This led to the development of an immersive system, which was tested with an elderly sample (15 participants) in a day center and at a retirement home. Usability, satisfaction, performance and side effects were evaluated to understand future applicability and work directions.
