“…HMD VR displays have been shown as suitable in reproducing several aspects of visual perception (e.g. pleasantness, excitement, or interest) in interior spaces when comparing real and virtual reality environments depicting both daylit (Chamilothori et al 2019b) and artificially lit scenes (Abd-Alhamid et al 2019;Higuera-Trujillo et al 2017). However, due the limited luminance range of the display in current HMD VR displays, some aspects of visual perception, such as glare, cannot be investigated.…”

Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the lighting levels, but they also affect how the space is perceived by its users. The present study examines three different window sizes via virtual reality, to study how they affect the perception of both a small and a large space at high latitudes. Additionally, two context scenarios (socializing and working), as well as three different sky types (overcast sky and clear skies with either high or low sun angle) were evaluated. The experimental study applied a mixed design with within-subjects and between-subjects factors. A total of 150 participants evaluated the scenes using a Likert-type scale to rate eight different subjective attributes. The statistical results showed that both window size and space type significantly affect the participants' spatial perception, as well as their satisfaction with the amount of outside view. Larger windows led to more positively evaluated spaces for all studied attributes. Moreover, a significant interaction was found between window size and type of space for the satisfaction with the amount of view in the space, indicating that the window size was dependent on the type of space in which the windows are located. Specifically, the window sizes were rated higher in the small space than in the large space for the evaluation of amount of view. The findings show that window size affects how people perceive a space, and additionally, that other spatial features, such as space type, affect window size preferences.

“…Although well-established questionnaires in terms of motion sickness are widely used, there is one evident drawback of such methods if compared to physiological evaluations; for instance, lengthy questionnaires are generally administered after a user has performed an experiment, therefore he/she has to shift attention away from the experiment and on the contrary has to focus on body feelings [10]. Physiological indicators are developed based on physiological signals such as heart rate variability, blood pressure, electrogastrography and galvanic skin reaction [5,17]. Dennision et al proposed other indicators that were not much studied in the scope of cybersickness, such as stomach activity, blinking and breathing [10].…”

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.

“…Several studies found that exposure to virtual environments in VR may have similar effects comparing to those in real environments. [38][39][40][41] Virtual display of natural environments in various settings (eg, forest, urban green space, streetscapes, biophilic indoor space) had been used to detect the effects on stress reduction, attention restoration, and cognitive function. [41][42][43][44] Eye-tracking, combined with VR, provides a unique opportunity to measure people's visual attention to specific elements in a simulated virtual environment by calculating the amount of time individual focuses on specific objects.…”

Effects of biophilic interventions in office on stress reaction and cognitive function: A randomized crossover study in virtual reality

Biophilia hypothesis suggests humans have an innate connection to nature which may affect our health and productivity. Yet we currently live in a world that is rapidly urbanizing with people spending most of their time indoors. We designed a randomized crossover study to let 30 participants experience three versions of biophilic design in simulated open and enclosed office spaces in virtual reality (VR). Throughout the VR session, we measured blood pressure, heart rate, heart rate variability, and skin conductance level and administered cognitive tests to measure their reaction time and creativity. Compared to the base case, participants in three spaces with biophilic elements had consistently lower level of physiological stress indicators and higher creativity scores. In addition, we captured the variation in the intensity of virtual exposure to biophilic elements by using eye‐tracking technology. These results suggest that biophilic interventions could help reduce stress and improve creativity. Moreover, those effects are related to both the types of biophilic elements and may be different based on the workspace type (open vs enclosed). This research demonstrates that VR‐simulated office spaces are useful in differentiating responses to two configurations and among biophilic elements.
