Abstract

This study investigated the effects of the time interval between virtual reality (VR) sessions on visually induced motion sickness (VIMS) reduction to better understand adaptation to and recovery from a nauseating VR experience. The participants experienced two 6-min VR sessions of a first-person motorcycle ride through a head-mounted display with (1) a 6-min interval, (2) an interval until the VIMS score reached zero, and (3) a 60-min interval. The results showed that for each condition, VIMS in the second session was aggravated, unchanged, or attenuated, respectively, indicating that additional resting time was necessary for VIMS adaptation. This study suggests that a certain type of multisensory learning attenuates VIMS symptoms within a relatively short time, requiring at least 20 min of additional resting time after subjective recovery from VIMS symptoms. This finding has important implications for reducing the time interval between repeated challenges when adapting to nauseating stimuli during VR experiences.

(a–c) FMS scores in the three interval groups: 6-min interval (a), personalised interval (b), and 60-min interval (c). In the personalised interval group, participants rested until their FMS score reached zero, after which they were immediately exposed to the VR session. The depicted line is the average of participants who have an FMS score > 0 in this group. Markers depicted in blue indicate FMS scores in the first session; duplicates of the first session scores are shown in grey in the background of the second session for the sake of direct comparison. (d) Cumulative ratio of participants who reached zero FMS in the interval between sessions for the personalised and 60-min interval groups.

The relationships between the log-transformed recovery time (minutes) and adaptation effect (% decrease) (a) and MSSQ (b). The number of plotted points is less than the number of participants because some points overlap. Marker size reflects the amount of overlapping data. Notably, in the personalised interval group, there was no extra resting time after the VIMS score reached zero.
