“…Though these studies focused on a different type of sickness, the effectiveness of the distraction approaches suggest that adding a task may reduce cybersickness. However, one study more closely aligned with the present one, trying to distract participants from cybersickness with a video-game like task (Zhou et al, 2019), found no significant results.…”

This study explored the impact of task workload on virtual reality (VR) cybersickness. Cybersickness is a negative side effect of using VR to which many users are susceptible. Previous research on the impact on task workload on cybersickness has yielded no consistent relationships, but given that task workload requires attentional resources, it is worth further investigation of how a demand on attention might increase or decrease cybersickness. In this study, mental workload of participants (N = 151) was modified in three different task groups within the same virtual environment (VE). The Cybersickness Corn Maze VR testbed contained cybersickness-inducing stimuli and tasks with varying workload. The 0-Back group used a controller to select an object as a visual attention task. The 2-Back group performed the 2-Back memory detection task, using a controller to collect objects that matched the object presented two objects ago. The No-Task group passively moved through the environment and was not given a controller. Workload, cybersickness, dropout rate, presence, and task accuracy were compared across groups. Workload was found to be statistically significantly different in each group: highest in the 2-Back group, medium in the 0-Back group, and lowest in the No-Task group, validating the task design. Cybersickness in the 2-Back group was significantly higher than in the No-Task (140% higher) and 0-Back (54% higher) groups measured by the change in simulator sickness questionnaire (SSQ) total severity (Post SSQ - Pre SSQ). The rate of participants’ dropout due to cybersickness was significantly higher in 2-back (33%) as compared with 0-Back (10%), but 0-Back and No-Task dropout rates were not significantly different. These results indicate that 1) task workload affects cybersickness and 2) its effect could be based on a threshold of workload. Presence increased with the addition of a task but plateaued between the 0-Back and 2-Back groups, suggesting that presence can be affected by task workload but only to a certain extent. Task accuracy was shown to negatively correlate with cybersickness within the task groups. A relationship between workload and cybersickness was found and warrants further research into these concepts. This work highlights the need for task workload and attention to be studied as components of the mechanisms underlying cybersickness.

“…The incidence of cybersickness might be slightly higher in adult population compared to pediatrics, but overall, it remains as low to be waivered. Adults also prefer to engage in the process of treatment and interact with their caregiver which might in uence the generalizability of the VR use in the adult population [17,39,40].

Introduction: Virtual Reality (VR) is a promising distraction technique that immerses the participant in a 3-dimensional virtual presence. The purpose of this study is to investigate the effect of VR on reducing pain in adult patients during laceration repair in the emergency department (ED). Methods: This is a randomized clinical trial conducted in the EDs of Rasoul Akram, Haftom-e-Tir and Firouzgar hospitals, all under supervision of Iran University of Medical Sciences. A total of 160 patients with laceration that needed suturing were divided into two equal groups of 80 patients; One group received the VR glasses during the suturing while the other group did not receive them. All patients in both groups received local analgesics. The pain intensity of the patients before and after the intervention was obtained using a numerical scale (from 1 to 10). Patient satisfaction was measured in terms of pain reduction based on a Likert scale: 1=bad, 2=poor, 3=moderate, 4=good, 5=excellent. The collected data of pain intensity and patient satisfaction were compared before and after the intervention. Results: The average age of patients in the VR+ group and VR- group was 37.04 ± 17.21 and 39.18 ±5.09 years, respectively. The average pain intensity of VR+ patients before and after using VR glasses were 4.87 ± 1.2 and 2.13 ± 1.32, respectively, of which demonstrated a significant reduction in the pain intensity of VR+ patients (P-value =0.028). The level of VR+ patients' satisfaction in terms of pain intensity before and after using VR glasses was 1.44 ± 0.52 and 3.23 ± 0.64, respectively, indicating a significant increase in the patients' satisfaction in terms of pain reduction after using VR glasses (P-value =0.033). Conclusion: VR has a positive effect on attenuating patients' pain and increasing their satisfaction in terms of pain reduction.

“…nausea, eyestrain) are distracting (Matsangas et al, 2014;Bos, 2015). Recently, Zhou et al (2019) showed that cognitive distraction in VR significantly decreases VIMS. Accordingly, the onset of VIMS can be thought to consume a portion of cognitive resources a driver possesses; attention allocated towards experiencing VIMS symptomatology decreases the amount of cognitive resources available to other tasks/experiences which use the same bank of cognitive resources.…”

Background: Virtual reality (VR) driving simulation technologies have a myriad of applications from entertainment to scientific and medical research. However, they also are known to cause visually induced motion sickness (VIMS), a special form of traditional motion sickness. Common side effects of VIMS include nausea and disorientation, suggesting VIMS can bias driving performance. Objectives: We (1) investigated how VIMS affects performance in a simulated driving task and (2) examined a potential treatment to reduce VIMS through in-vehicle ventilation. Method: Twenty-three participants were engaged in a driving task where they react to hazards, obey speed limits, and complete common driving maneuvers. Driving performance (Objective 1) was evaluated based on various common driving criteria and compared between high- and low VIMS groups. To study the effect of airflow on VIMS (Objective 2), for half of the participants the car vents were positioned to face the drivers head and torso having airflow directly contact the driver’s skin, creating the experimental group: airflow (direct, indirect). The level of VIMS was measured before and after the simulated drive. Results: We found no differences in VIMS severity between airflow groups, indicating both direct and indirect airflow were equally successful prophylaxes to VIMS. We found no differences in driving performance between participants who experienced high- and low VIMS, indicating driving performance was not influenced by VIMS. Conclusion: Due to their equal prophylactic effects, both direct and indirect airflow can be used as a low cost, effective means of reducing VIMS in VR driving simulators. Furthermore, as driving-performance was not affected by VIMS, driving-simulator results of participants who experience high levels of VIMS can be treated equal to participants who experience low levels of VIMS. As these results are preliminary given we were unable to reach our minimum sample size of 40 participants, more data collection is required in order to be able to make a concrete conclusion.
