Visually Induced Motion Sickness Research Articles

Implementing virtual reality technology to teach medical college systemic anatomy: A pilot study.

It can be difficult for some students to learn three-dimensional anatomical structure concepts. While virtual reality (VR) systems have been reported as helpful for learning, there has been scarce research on either VR teaching strategies or the influence of visually induced motion sickness (VIMS) in the context of large anatomy classes (i.e., over 100 students). The study thus aimed to (1) establish a VR anatomy instruction video for a large class; (2) determine how many students experience VIMS when watching a VR anatomy instruction video; (3) evaluate the influence of VIMS on VR anatomy video-based learning; and (4) examine whether a small screen size alleviates VIMS. Laboratory course students viewing a VR anatomy instruction video about the vascular system were invited to participate in the questionnaire survey. Anatomy faculty and staff participated in an experimental trial to determine whether small screen size could alleviate VIMS. The Likert scale survey revealed that students reported the VR strategy as advantageous and appropriate for large classes, but that it cannot replace practical dissection. Of the total participants, 32% reported experiencing VIMS, and 40% of those experiencing VIMS agreed that this could negatively impact their learning through a VR anatomy instruction video. Adjusting the screen size from large to small significantly delayed the onset of VIMS. In conclusion, the VR anatomy instruction video strategy is feasible and helpful for large classes, but educators should consider VIMS when planning their use of this teaching approach.

Novel neurodigital interface reduces motion sickness in virtual reality

Virtual reality (VR) is a computer-created 3D environment with a focus on realistic scenes and pictures created for entertainment, medical and/or educational and training purposes. One of the major side effects of VR immersion reported in the scientific literature, media and social media is Visually Induced Motion Sickness (VIMS), with clinical symptoms such as disorientation, nausea, and oculomotor discomfort. VIMS is mostly caused by the discrepancy between the visual and vestibular systems and can lead to dizziness, nausea, and disorientation. In this study, we present one potential novel solution to combat motion sickness in VR, showcasing a significant reduction of nausea in VR users employing the META Quest 2 headsets in conjunction with a whole-body controller. Using a neurodigital approach, we facilitate a more immersive and comfortable VR experience. Our findings indicate a marked reduction in VR-induced nausea, paving the way to promote VR technology for broader applications across various fields.

The role of lifestyle factors, biological sex, and racial identity for (visually induced) motion sickness susceptibility: Insights from an online survey

Motion sickness (MS) and visually induced motion sickness (VIMS) are common side-effects when travelling or when using visual devices, respectively. A variety of individual factors may determine one’s susceptibility to MS/VIMS. Here, the role of lifestyle factors including video-game usage, physical activity, diet, and substance use on self-reported susceptibility to MS/VIMS was investigated. Additionally, the roles of biological sex and racial identity on the overall prevalence of MS/VIMS were analyzed. A total of 711 responses to an online survey were collected from adults between the ages of 17–49 years. Methods of analyses included correlations, comparison tests, and multiple regressions. The results showed that, overall, VIMS is a prevalent issue for most participants, with approximately 24 % of users reporting nausea at least sometimes when using visual displays. Although some lifestyle factors (video game usage, assorted dietary elements) were identified as potentially relevant for MS/VIMS susceptibility, these factors only explained a minimal amount of the variance in MS/VIMS susceptibility. Significant sex differences were found, with female participants reporting higher susceptibility for MS/VIMS than male participants. Additionally, East Asians participants reported higher MS susceptibility. Our findings do not suggest that lifestyle factors are prominent predictors for the susceptibility of VIMS and MS.

Poster Session I: Perspective-correct rendering for active observers.

Stereoscopic, head-tracked display systems can show users realistic, world-locked virtual objects and environments (i.e., rendering perspective-correct binocular images with accurate motion parallax). However, discrepancies between the rendering pipeline and physical viewing conditions can lead to perceived instability in the rendered content resulting in reduced immersion and, potentially, visually-induced motion sickness. Precise requirements to achieve perceptually stable world-locked rendering (WLR) are unknown due to the challenge of constructing a wide field of view, distortion-free display with highly accurate head and eyetracking. We present a custom-built system capable of rendering virtual objects over real-world references without perceivable drift under such constraints. This platform is used to study acceptable errors in render camera position for WLR in augmented and virtual reality scenarios, where we find an order of magnitude difference in perceptual sensitivity. We conclude with an analytic model which examines changes to apparent depth and visual direction in response to camera displacement errors, and visual direction is highlighted as a potentially important consideration for WLR alongside depth errors from incorrect disparity.

Investigation of the Correlation Between the Visually Induced Motion Sickness Susceptibility Questionnaire and the Turkish Motion Sickness Susceptibility Questionnaire.

Visually induced motion sickness (VIMS) is a phenomenon similar to motion sickness frequently observed in users of visual technologies. The Visually Induced Motion Sickness Susceptibility Questionnaire (VIMSSQ), developed by Golding et al. (2006), is considered the most effective scale for assessing VIMS susceptibility levels. The main purpose of this study was to standardize the selection of participants for research conducted with virtual reality, especially motion sickness (MS) research. To achieve this, first, the Turkish version of the VIMSSQ was created to establish its validity and reliability, and subsequently, its correlation with the Turkish Motion Sickness Susceptibility Questionnaire Short form (HDDA), the expanded version of the Motion Sickness Susceptibility Questionnaire Short form (MSSQ), was examined. Subjects and. Linguistic equivalence assessment was obtained from ten experts by passing the VIMSSQ through the translation process. The VIMSSQ and the Turkish MSSQ forms were then administered to 49 subjects. This study statistically analyzed the validity and reliability of the VIMSSQ and its relationship with the MSSQ. Results showed that the Turkish version of the original questionnaire is highly reliable (Cronbach alpha=0.843). There is a moderate statistically significant positive correlation between the total MSSQ scores and the subfactors of the VIMSSQ. In this study, VIMSSQ was successfully adapted to Turkish, normative data demonstrated its validity, and all sub-factors were highly reliable. The Turkish version of the VIMSSQ can serve as a valuable tool for estimating individual susceptibility to VIMS.

Assessment of individual differences for aftereffect of viewing autostereoscopic 3D display

AbstractThe representation of images on autostereoscopic 3D display often suffers from visual fatigue induced by stereoscopic images (VFSI) and visually induced motion sickness (VIMS), deriving from conflict between accommodation and convergence and from mismatches between vestibule system and visual system of viewers, respectively. In this study, a subjective experiment was conducted to investigate the implications of age and gender on the visual discomfort when watching the 3D video clips with four levels of parallax on autostereoscopic 3D display. This study found that the age of observers significantly affected both VFSI and VIMS symptoms. The young observers reported more serious VFSI and VIMS symptoms than the middle and elderly, while the three age groups had significantly pairwise difference for VIMS symptoms. Although gender differences did not exist in the ratio of VFSI symptoms, females had significant higher VIMS scores than males. The effect of parallax on symptom scores varied with age and gender. The elderly and male observers could endure larger parallax when compared to other groups. Furthermore, considering viewing safety for observers, it is recommended to limit parallax to a threshold of 40′.

Exploring neurophysiological correlates of visually induced motion sickness using electroencephalography (EEG).

Visually induced motion sickness (VIMS) is a common phenomenon when using visual devices such as smartphones and virtual reality applications, with symptoms including nausea, fatigue, and headache. To date, the neuro-cognitive processes underlying VIMS are not fully understood. Previous studies using electroencephalography (EEG) delivered mixed findings, with some reporting an increase in delta and theta power, and others reporting increases in alpha and beta frequencies. The goal of the study was to gain further insight into EEG correlates for VIMS. Participants viewed a VIMS-inducing visual stimulus, composed of moving black-and-white vertical bars presented on an array of three adjacent monitors. The EEG was recorded during visual stimulation and VIMS ratings were recorded after each trial using the Fast Motion Sickness Scale. Time-frequency analyses were conducted comparing neural activity of participants reporting minimal VIMS (n = 21) and mild-moderate VIMS (n = 12). Results suggested a potential increase in delta power in the centro-parietal regions (CP2) and a decrease in alpha power in the central regions (Cz) for participants experiencing mild-moderate VIMS compared to those with minimal VIMS. Event-related spectral perturbations (ERSPs) suggested that group differences in EEG activity developed with increasing duration of a trial. These results support the hypothesis that the EEG might be sensitive to differences in information processing in VIMS and minimal VIMS contexts, and indicate that it may be possible to identify neurophysiological correlate of VIMS. Differences in EEG activity related to VIMS may reflect differential processing of conflicting visual and vestibular sensory information.

Brain activity differences between susceptible and non-susceptible populations under visually induced motion sickness based on sensor-space and source-space analyses

The neural mechanisms underlying visually induced motion sickness (VIMS) in different susceptible populations are unclear, as it is not clear how brain activity changes in different susceptible populations during the vection section (VS). This study aimed to analyze the brain activity changes in different susceptible populations during VS. Twenty subjects were included in this study and divided into the VIMS-susceptible group (VIMSSG) and VIMS-resistant group (VIMSRG) based on a motion sickness questionnaire. 64-channel electroencephalogram (EEG) data from these subjects during VS were collected. The brain activities during VS for VIMSSG and VIMSRG were analyzed with time–frequency based sensor-space analysis and EEG source imaging based source-space analysis. Under VS, delta and theta energies were significantly increased in VIMSSG and VIMSRG, while alpha and beta energies were only significantly increased in VIMSRG. Also, the superior and middle temporal were activated in VIMSSG and VIMSRG, while lateral occipital, supramarginal gyrus, and precentral gyrus were activated only in VIMSSG. The spatiotemporal differences in brain activity observed between VIMSSG and VIMSRG may be attributed to the different susceptibility of participants in each group and the different severity of MS symptoms experienced. Long-term vestibular training can effectively improve the ability of anti-VIMS. The knowledge gained from this study helps advance understanding of the neural mechanism of VIMS in different susceptible populations.

Complications associated with the use of virtual reality therapy during the treatment of postoperative pain

Relevance. The therapy based on virtual reality is used as a method of non-pharmacological treatment of postoperative pain. Possible complications are poorly understood, making it difficult to use in everyday clinical practice.The objective was the evaluation of the development of complications when using therapy based on virtual reality in the treatment of postoperative pain syndrome.Materials and methods. A prospective clinical study was performed. 90 patients who had to perform surgical interventions were included. After randomization, three groups were formed: group I (n = 30) – therapy with a 15-minute session as an addition to standard therapy for postoperative pain, group II (n = 30) – therapy with a 25-minute session, and group III (n = 30) receiving only drug treatment of postoperative pain syndrome. Virtual reality-based therapy (VR-therapy) was performed 3, 7, 12 hours after surgery using the Oculus Quest 2 device. Postoperative nausea, vomiting and dizziness were considered complications of VR-therapy. The development of complications was assessed using the FMS (Fast Motion Sickness Scale) self-assessment of motion sickness and the Postoperative Nausea and Vomiting Scale (PONV). The quality of the patient’s recovery after anesthesia was assessed using the QoR-15 scale.Results. There were no differences in the incidence of visually induced motion sickness between groups with different session durations. The incidence of postoperative nausea and vomiting and the need for antiemetic drugs did not differ between the main and control groups. A positive correlation was found between the occurrence of visually induced motion sickness (VIMS) and the use of opioid drugs in the postoperative period. In patients with a VR-therapy session duration of 25 minutes, the indicators of the quality of recovery after anesthesia were higher than in other groups.Conclusions. The use of VR-therapy with a session of 15 and 25 minutes does not lead to an increase in the incidence of postoperative nausea and vomiting. The duration of therapy did not affect the development of VIMS. The indicators of the quality of recovery after anesthesia in the group with a duration of VR-therapy of 25 minutes were higher than in other groups.

O023 Effectiveness of augmented reality for surgical training of medical students: a systematic review and meta-analysis

Abstract Introduction Interest in augmented reality (AR) technologies within an educational setting have surged in recent years. However, few studies evaluate the use of AR in a primarily medical student population. This systematic review with meta-analysis intended to evaluate the existing literature on this topic. Methods This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Using relevant synonyms for the terms augmented reality, surgery and medical students, the databases Medline, Embase, and Scopus were searched. Data was extracted for outcome measures such as time for task completion, errors/fails, attempts/retries, motion sickness/nausea and focus shifts. Results Some 826 records were initially retrieved; 19 studies were included in our review, with a total of 485 participants. The AR group performed better than the comparator group in 84% of the statistically significant main outcomes. The AR groups were less likely to fail assessment, with a pooled odds ratio of 1.76 (95% CI:0.06-51.71, p=0.74, I2=81%). One study reported 57% fewer critical errors than the comparator group. Only two studies reported nausea/motion sickness as an outcome (12% (n=3) and mean Likert-scale score of 3 (of 10) in the AR groups). Conclusion AR can be an effective surgical teaching and training tool for medical students. However, the limitations of AR, including visually-induced motion sickness, have not yet been explored extensively by primary studies with a medical student population. Therefore, gradual integration of AR is proposed until further studies elucidating benefits and risks can be undertaken.

Effects of Seated Postural Sway on Visually Induced Motion Sickness: A Multiple Regression and RUSBoost Classification Approach

The purpose of this study was to propose a model for estimating individual susceptibility to motion sickness by correlating measures of seated postural sway before exposure to a roller coaster movie displayed in a head-mounted display (HMD) with subjective ratings of visually induced motion sickness (VIMS). The participants were required to watch the content for 15 min, and seated center of pressure (sCOP) was measured using a force platform for 5 min before viewing. We developed a VIMS estimating model from 16 subjects and verified it on 15 subjects. SSQ scores for VIMS were strongly correlated with the area of sCOP, the main-to-minor ratio of the sCOP ellipse, and the total length of sCOP, respectively (r = 0.706, r = 0.555, and r = 0.622). When verifying the estimation model, the observed SSQ scores differed by 32.628 ± 29.749 from the expected SSQ scores, and both score sets were positively correlated (r = 0.622). The classification results between nil and mild, moderate, and severe groups for VIMS showed an accuracy of 0.74 using random under-sampling boost (RUSBoost).

Measuring the susceptibility to visually induced motion sickness and its relationship with vertigo, dizziness, migraine, syncope and personality traits

The widespread use of visual technologies such as Virtual Reality increases the risk of visually induced motion sickness (VIMS). Previously, the 6-item short version of the Visually Induced Motion Sickness Susceptibility Questionnaire (VIMSSQ short form) has been validated for predicting individual variation in VIMS. The aim of the current study was to investigate how the susceptibility to VIMS is correlated with other relevant factors in the general population. A total of 440 participants (201 M, 239F), mean age 33.6 (SD 14.8) years, completed an anonymous online survey of various questionnaires including the VIMSSQ, Motion Sickness Susceptibility Questionnaire (MSSQ), Vertigo in City questionnaire (VIC), Migraine (scale), Social & Work Impact of Dizziness (SWID), Syncope (faintness), and Personality (‘Big Five’ TIPI). The VIMSSQ correlated positively with the MSSQ (r = 0.50), VIC (r = 0.45), Migraine (r = 0.44), SWID (r = 0.28), and Syncope (r = 0.15). The most efficient Multiple Linear Regression model for the VIMSSQ included the predictors MSSQ, Migraine, VIC, and Age and explained 40% of the variance. Factor analysis of strongest correlates with VIMSSQ revealed a single factor loading with VIMSSQ, MSSQ, VIC, Migraine, SWID, and Syncope, suggesting a common latent variable of sensitivity. The set of predictors for the VIMSSQ in the general population has similarity with those often observed in patients with vestibular disorders. Based on these correlational results, we suggest the existence of continuum of underlying risk factors for sensitivity, from healthy population to patients with extreme visual vertigo and perhaps Persistent Postural-Perceptual Dizziness.

Determining Work-Rest Schedules for Visual Tasks That Use Optical Head-Mounted Displays Based on Visual Fatigue and Visually Induced Motion Sickness Recovery.

This study aimed to determine work-rest schedules for visual tasks of different lengths by evaluating visual fatigue and visually induced motion sickness (VIMS) using an optical head-mounted display (OHMD). Thirty participants were recruited to perform 15 and 30 min visual tasks using an OHMD. After completing each visual task, participants executed six levels of rest time. Critical flicker fusion frequency (CFF) values, relative electroencephalography indices, and Simulator Sickness Questionnaire (SSQ) scores were collected and analyzed. Results indicated that after completing the 15 and 30 min visual tasks, participants experienced visual fatigue and VIMS. There was no significant difference between baseline CFF values, four electroencephalography relative power index values, and SSQ scores when participants completed a 15 min visual task followed by a 20 min rest and a 30 min visual task followed by a 30 min rest. Based on our results, a 20 min rest for visual fatigue and VIMS recovery after a 15 min visual task on an OHMD and a 25 min rest for visual fatigue and VIMS recovery after a 30 min visual task on an OHMD are recommended. This study suggests a work-rest schedule for OHMDs that can be used as a reference for OHMD user guidelines to reduce visual fatigue and visually induced motion sickness.

Visual function impairment in patients suffering from visually induced motion sickness. A preliminary observational longitudinal study

Objective Visually induced Motion Sickness (VIMS) is a side effect induced by the physical motion of the person or visual motion that adversely affects otherwise individuals and decreases safety in situations that require high levels of concentration. The exact mechanisms behind the emergence of VIMS are still unknown but can be triggered by direct or indirect stimuli due to mismatches in the visual-vestibular autonomic pathways. The aim of this preliminary study was to explore the presence of visual dysfunctions in patients suffering from VIMS and then evaluate the potential role of a customized visual training (VT) on their perceived sickness symptoms. Methods A total of 9.675 medical records of patients who referred motion sickness were reviewed; 455 patients with a diagnosis of VIMS were included. A total of 95 patients (86 females and 9 males, mean age of 37,68 ± 9.20 years) met the inclusion criteria and were enrolled in this study. Two evaluation sessions were carried out immediately before (T0) and after 16 weeks (T1) of visual training (VT). The main goal of VT was to facilitate the visual center-periphery integration. VT was performed 1 day/week/16 weeks under therapist supervision in the Optometric centre and 5 days/week/16 weeks at home without supervision. Results The within-subjects comparison at times T0–T1 showed significant improvement of the symptoms in all the included patients. Conclusion Our results support the hypothesis that patients suffering from VIMS may present also a visual function impairment that can increase the dizziness-related symptoms. Furthermore, visual training can help patients with VIMS and visual dysfunction in reducing capture discomfort, stomach awareness, and nausea.

EEG-based analysis of various sensory stimulation effects to reduce visually induced motion sickness in virtual reality

The use of virtual reality (VR) is frequently accompanied by motion sickness, and approaches for preventing it are not yet well established. We explored the effects of synchronized presentations of sound and motion on visually induced motion sickness (VIMS) in order to reduce VIMS. A total of 25 participants bicycle riding for 5 min with or without sound and motion synchronization presented on a head-mounted display. As a result, the VIMS scores measured by the fast motion sickness scale and simulator sickness questionnaire were significantly lower in the participants who experienced the riding scene with sound and motion than those who experienced the riding scene with sound only, motion only, or neither. Furthermore, analysis of the EEG signal showed that the higher the VIMS, the significant increase in alpha and theta waves in the parietal and occipital lobes. Therefore, we demonstrate that the simultaneous presentation of sound and motion, closely associated with synchronous and visual flow speed, is effective in reducing VIMS while experiencing simulated bicycle riding in a VR environment.

A modularity design approach to behavioral research with immersive virtual reality: A SkyrimVR-based behavioral experimental framework.

Virtual reality (VR) has been shown to be a potential research tool, yet the gap between traditional and VR behavioral experiment systems poses a challenge for many behavioral researchers. To address the challenge posed, the present study first adopted a modularity design strategy and proposed a five-module architectural framework for a VR behavioral experiment system that aimed to reduce complexity and costs of development. Applying the five-module architectural framework, the present study developed the SkyrimVR-based behavioral experimental framework (SkyBXF) module, a basic experimental framework module that adopted and integrated the classic human behavior experiment structure (i.e., session-block-trial model) with the modifiable VR massive gaming franchise The Elder Scrolls V: Skyrim VR. A modified version of previous behavioral research to investigate the effects of masked peripheral vision on visually-induced motion sickness in an immersive virtual environment was conducted as a proof of concept to showcase the feasibility of the proposed five-module architectural framework and the SkyBXF module developed. Behavioral data acquired through the case study were consistent with those from previous behavioral research. This indicates the viability of the proposed five-module architectural framework and the SkyBXF module developed, and provides proof that future behavioral researchers with minimal programming proficiency, 3D environment development expertise, time, personnel, and resources may reuse ready-to-go resources and behavioral experiment templates offered by SkyBXF to swiftly establish realistic virtual worlds that can be further customized for experimental need on the go.

Emotions are associated with the genesis of visually induced motion sickness in virtual reality

Visually induced motion sickness (VIMS) is a well-known side effect of virtual reality (VR) immersion, with symptoms including nausea, disorientation, and oculomotor discomfort. Previous studies have shown that pleasant music, odor, and taste can mitigate VIMS symptomatology, but the mechanism by which this occurs remains unclear. We predicted that positive emotions influence the VIMS-reducing effects. To investigate this, we conducted an experimental study with 68 subjects divided into two groups. The groups were exposed to either positive or neutral emotions before and during the VIMS-provoking stimulus. Otherwise, they performed exactly the same task of estimating the time-to-contact while confronted with a VIMS-provoking moving starfield stimulation. Emotions were induced by means of pre-tested videos and with International Affective Picture System (IAPS) images embedded in the starfield simulation. We monitored emotion induction before, during, and after the simulation, using the Self-Assessment Manikin (SAM) valence and arousal scales. VIMS was assessed before and after exposure using the Simulator Sickness Questionnaire (SSQ) and during simulation using the Fast Motion Sickness Scale (FMS) and FMS-D for dizziness symptoms. VIMS symptomatology did not differ between groups, but valence and arousal were correlated with perceived VIMS symptoms. For instance, reported positive valence prior to VR exposure was found to be related to milder VIMS symptoms and, conversely, experienced symptoms during simulation were negatively related to subjects’ valence. This study sheds light on the complex and potentially bidirectional relationship of VIMS and emotions and provides starting points for further research on the use of positive emotions to prevent VIMS.

Optical see-through augmented reality can induce severe motion sickness

The aim was to investigate whether severe symptoms of visually induced motion sickness (VIMS) can occur in augmented reality (AR) optical see-through applications. VIMS has been extensively studied in virtual reality (VR), whereas it has received little attention in the context of AR technology, in which the real world is enhanced by virtual objects. AR optical see-through glasses are becoming increasingly popular as technology advances. Previous studies showed minor oculomotor symptoms of VIMS with the aforementioned technology. New applications with more dynamic simulations could alter previously observed symptom severity and patterns. In experiment 1, we exposed subjects to a traditional static AR application for pilot candidate training. In experiment 2, subjects completed tasks in a dynamic starfield simulation. We analyzed symptom profiles pre and post with the simulator sickness questionnaire (SSQ) and during exposure with the Fast Motion Sickness Scale (FMS). We also developed a new FMS-D that captures symptoms of dizziness during simulation. As expected, in experiment 1 we found low VIMS symptomatology with predominantly oculomotor symptoms. In experiment 2, on the other hand, we detected severe VIMS symptoms in some subjects, with disorientation (SSQ subscale) as the main symptom group. The present work demonstrates that VIMS can be of serious concern in modern AR applications. The FMS-D represents a new tool to measure symptoms of dizziness during exposure. VIMS symptoms need to be considered in the design and usage of future AR applications with dynamic virtual objects, e.g. for flight training or machine maintenance work.

Evaluating binaural beats as a therapeutic tool for intervening visually-induced motion sickness in virtual reality environments

Background: Visually-induced motion sickness (VISM) is an emerging problem in the application of virtual reality (VR) technology. Binaural beats are proven to be effective in reducing anxiety levels and enhancing pain management in VR environments. They may have the potential to be a remedy for symptoms of visually-induced motion sickness. Objective: To investigate whether binaural beats can effectively ease the symptoms of VIMS. Methods: Motion sickness susceptible individuals (n=35) were assigned to wear VR headsets and watch a 15-min VR video to evoke VIMS. Whenever motion sickness was self-reported by subjects, they were randomized into three groups receiving three types of intervention methods: Subjects in the experimental group listened to binaural beats; The control group was treated with beats of the same frequency at two soundtracks. And the blank group recovered without any sound played in the earphones. Subjects filled in the Simulator Sickness Questionnaires (SSQ) at three stages—before watching the VR video (baseline), during the watching experience (induction), and after watching (recovery). To increase the credibility, their physiological data were collected by a Biofeedback device during the whole process. Results: Participants’ subjective SSQ scores were analyzed, which did not reveal any significant difference between recovery and induction (p>0.05). The physiological data were following the result obtained from analyzing SSQ scores. Conclusion: The binaural beats did not show a significant effect of alleviating VISM.

Detecting and predicting visually induced motion sickness with physiological measures in combination with machine learning techniques

Visually induced motion sickness (VIMS) is a common sensation when using visual displays such as smartphones or Virtual Reality. In the present study, we investigated whether Machine Learning (ML) techniques in combination with physiological measures (ECG, EDA, EGG, respiration, body and skin temperature, and body movements) could be used to detect and predict the severity of VIMS in real-time, minute-by-minute. A total of 43 healthy younger adults (25 female) were exposed to a 15-minute VIMS-inducing video. VIMS severity was subjectively measured during the video using the Fast Motion Sickness Scale (FMS) as well as before and after the video using the Simulator Sickness Questionnaire (SSQ). Thirty-one participants (72%) experienced VIMS in the present study. Results showed that changes in facial skin temperature and body movement had the strongest relationship with VIMS. On a minute-by-minute basis, ML models revealed a medium correlation between the physiological measures and the FMS scores. An acceptable classification score distinguishing between sick and non-sick participants was found. Our findings suggest that physiological measures may be useful for measuring VIMS, but they are not a reliable standalone method to detect or predict VIMS severity in real-time.
