“…To this end, individuals can rely on either a visual, gravitational, or egocentric frame of reference (FoR -Ohlmann, 1988), based on visual, vestibular and somesthesic cues respectively (Isableu et al, 2010). Each FoR is attributed aweight (Ohlmann, 1990), implying the dominance of one of them for performance in tasks requiring geocentric perception. However, the dominance hierarchy of FoR, varies from one individual to another.…”

Accurately perceiving the gravitational direction is key to successful interaction in our terrestrial environment. In this context field dependence (FD), the importance given to static and/or dynamic visual cues, has largely been discussed. Although first considered a trait, several studies suggest FD be flexible in response to postural or visual contexts and to poor virtual reality user experience. The aim of this study was therefore to determine the influence of a disruptive virtual immersion on the level of static and dynamic FD. Forty-five participants were exposed to a virtual maritime environment for up to 14 minutes.Cybersickness and sense of presence were measured. Before and after virtual immersion, the Rod and Frame Test and the Rod and Disc Test were performed to assess static and dynamic FD respectively. We demonstrated a significant decrease in both levels of FD after immersion in initially more dependent participants. Decrease in static FD was explained by high initial static FD and severe cybersickness, while decrease in dynamic FD was only explained by the initial level of dynamic FD. In this study, we provide evidence confirming FD flexibility, likely reflecting an adaptation process to environmental or individual-related constraints. Yet, static and dynamic FD seem to rely on separate mechanisms, highlighting the necessity to specify which characteristic of visual information (static or dynamic) individuals depend on when assessing their FD. Our results question the reliability of virtual reality for perceptive or motor diagnoses without considering its consequences, specifically in vulnerable populations such as the elderly.
