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.

“…The observation of depth gaze associated with veridical depth information during exposure in VEs becomes paramount. Wibirama et al [33] carried out a comprehensive study on VIMS with respect to the SSQ, electrocardiography (ECG) as well as 3D gaze tracking. The occurrence of VIMS was investigated with the SSQ, then the result was utilized for the analysis of user behaviors according to ECG and 3D gaze tracking; they found that participants immersed in 3D visual contents can have less dominant sympathetic nerves activated due to voluntary gaze fixation at one point, which suggests that depth gaze oscillates more frequently when VIMS appears.…”

This paper proposes a new objective metric of visually induced motion sickness (VIMS) in the context of navigation in virtual environments (VEs). Similar to motion sickness in physical environments, VIMS can induce many physiological symptoms such as general discomfort, nausea, disorientation, vomiting, dizziness and fatigue. To improve user satisfaction with VR applications, it is of great significance to develop objective metrics for VIMS that can analyze and estimate the level of VR sickness when a user is exposed to VEs. One of the well-known objective metrics is the postural instability. In this paper, we trained a LSTM model for each participant using a normal-state postural signal captured before the exposure, and if the postural sway signal from post-exposure was sufficiently different from the pre-exposure signal, the model would fail at encoding and decoding the signal properly; the jump in the reconstruction error was called loss and was proposed as the proposed objective measure of simulator sickness. The effectiveness of the proposed metric was analyzed and compared with subjective assessment methods based on the simulator sickness questionnaire (SSQ) in a VR environment, achieving a Pearson correlation coefficient of .89. Finally, we showed that the proposed method had the potential to be deployed within a closed-loop system and get real-time performance to predict VR sickness, opening new insights to develop user-centered and customized VR applications based on physiological feedback.

“…Their findings still leave a research question whether the results are valid as each participant while bias may perceive a written questionnaire differently and ambiguity in the questionnaire can affect the research results significantly [12]. These drawbacks can be resolved by implementing behavioral or physiological measurements, such as eye tracking and electrocardiography [13][14][15][16][17][18][19]. To the best knowledge of the authors, however, previous works lack sufficient understanding on how parallax scrolling affects visual object localization while accessing information in a website.…”

Parallax scrolling technique is being devoted as a unique and an innovative trend in the web design. Parallax scrolling provides 3D perception on a web page. Previous works observed user experience issues of parallax scrolling merely based on subjective questionnaires. Their findings leave a research question whether the results are valid, as participants may perceive a written questionnaire differently. Additionally, bias and ambiguity in the questionnaire can affect the research results significantly. To solve this research problem, we present a novel user experience study of parallax scrolling in storytelling and online shop website using eye tracking and User Experience Questionnaire (UEQ). Forty (N=40) participant joined the experiment on a voluntary basis. Each participant only interacted with one out of two websites (storytelling or online shop) and only one effect (with or without parallax scrolling). We found that parallax scrolling affected UEQ score of Attractiveness of the storytelling website (p < 0.05). Our findings suggest that parallax scrolling improves user engagement in storytelling website. We also observed that the participants spent time almost two times faster to find an object of interest in an online shop with parallax scrolling compared with the similar task in an online shop without parallax scrolling (p < 0.05). We thus argue that parallax scrolling is useful during interacting with particular websites that require visual object localization. In future, web designers should consider the appropriate usage of parallax scrolling to optimize user experience while avoiding additional distraction caused by this technique.
