“…The scope of this research was limited to pleasant and horror environment genres. The choice of the selected genre was based on [25], i.e. using flamboyant imagery in day scene for a pleasant virtual environment whereas grotesque imagery for stressed and horror virtual environment.…”

“…Furthermore, the virtual environment illuminance is another factor that affects the amount of VIMS. It is reported that dark rooms can be more stressing than the brighter ones and stress is a factor of motion sickness [25]. Similarly, bright rooms produce less amount of eye fatigue as compared to dark places hence limiting VIMS.…”

“…In line with the previous work, it is evident that VR experience and motion sickness experience has a relationship with initiating motion sickness in VR systems. Moreover, the severity of motion sickness can be dangerous, and novice users must make their physical assessments before diving into the VR experience [25].…”

Due to rapid growth in Virtual Reality (VR) technology, the industry of VR is expected to grow around $26.89 billion by 2022. However, with its extensive growth and immersive inclusion in human life, health-related issues are reported including, but not limited to nauseated feeling, vomiting, dizziness and cold sweats. These issues introduce a well-known side effect termed as motion sickness in VR users. Consequently, motion sickness limits the VR community in the full adaptation of this immersive technology. Since there is no lack of literature investigating motion sickness caused by VR, yet researches on the effect of VR on human's physiology is still in its infancy. This study presents novel findings, by comparing different factors such as gender, motion sickness experience, 3D games experience and VR experience. Furthermore, it reports the impact of concerning factors in a within-subjects design (46 participants participated in an experiment) under different virtual environment genres. The key findings of this article report that there is a significant difference in the amount of motion sickness when shifting from pleasant to the horror genre of the environment and having a strong dependence on gender. Moreover, the type of virtual environment is an essential factor that has a notable effect on the user's blood pressure, blood sugar and heart rate. However, past experiences with motion sickness and 3D games show no significant impact on the user's level of motion sickness.

Objective This study aimed to examine the effectiveness, safety and patients’ perceptions of an immersive virtual reality (VR)–based exercise system for poststroke upper limb rehabilitation. Methods A proof-of-concept, 2-week randomized controlled trial was conducted. Fifty stroke patients were randomly assigned to either use the immersive VR-based exercise system to perform upper limb exercises for 2 weeks (intervention) or play commercial games (control). Effectiveness, safety and patients’ perceptions of the exercise system were assessed at baseline and at 1- and 2-week follow-ups. Results Intention-to-treat analysis revealed that after 2 weeks, statistically significant improvements in shoulder flexion active range of motion (AROM), shoulder abduction AROM, perceived upper limb motor function and quality of life (QoL) were observed in one or both groups, but not between the groups. Per-protocol analysis showed that after 2 weeks: (i) statistically significant improvement in shoulder abduction AROM was obtained in the intervention group, and the difference in the mean changes between the groups was statistically significant; (ii) statistically significant improvements in coordination/speed (Fugl–Meyer Assessment for Upper Extremity), shoulder flexion AROM, perceived upper limb motor function and QoL were obtained in one or both groups, but not between the groups. Conclusions The immersive VR-based exercise system is a potentially effective, safe and acceptable approach for supporting poststroke motor rehabilitation. These findings can serve as a basis for larger-scale studies on the application of VR for poststroke exercises.
