“…Psychology research into human factors frequently uses simulations instead of physical environments to assess psychological and physiological responses to environments. Although 16 no platform or format can exactly reproduce physical environment (Moscoso et al, 2015), these environmental simulations have clear advantages for scientific purposes in controlled conditions. The validity of these simulations depends on the similarity of their results to those acquired by physical environment.…”

Psychological research into human factors frequently uses simulations to study the relationship between human behaviour and the environment. Their validity depends on their similarity with the physical environments. This paper aims to validate three environmental-simulation display formats: photographs, 360° panoramas, and virtual reality. To do this we compared the psychological and physiological responses evoked by simulated environments set-ups to those from a physical environment setup; we also assessed the users' sense of presence. Analysis show that 360° panoramas offer the closest to reality results according to the participants' psychological responses, and virtual reality according to the physiological responses. Correlations between the feeling of presence and physiological and other psychological responses were also observed. These results may be of interest to researchers using environmental-simulation technologies currently available in order to replicate the experience of physical environments.

“…Studies that focus on the impact of window size and of sunlight on perception have repeatedly emphasized the difficulty of ensuring the stability of the experimental conditions (Boubekri et al 1991;Wang and Boubekri 2010), which limits the validity and reproducibility of research findings. In order to overcome the methodological constraints that daylighting studies may present, stereoscopic imaging has been used as a research tool in experimental lighting research (Cauwerts and Bodart 2011;Moscoso et al 2015b). Moreover, for increase realism, the level of perceived immersion achieved by using virtual reality (VR) is even higher than the aforementioned studied modes due to the lack of conflicting stimuli from the peripheral vision.…”

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.

“…The decision to exclude glare as a study variable was also made because of the limitations of the stereoscopic pictures method. Although a previous study had already validated the method as reliable for the assessment of the perceived quality of interiors, 27 it needs to be stated that the stereoscopic pictures do not match the luminances of a real room, thus making glare studies challenging.…”

The quality of a lit environment cannot be deduced solely from the quantity of light. Therefore, daylighting studies should not only be focused on the usage of lighting metrics but should also consider the aesthetic experience. This paper examines the influence of daylighting systems on the aesthetic perception of a small office. One single side lit office was equipped with four different daylighting systems (white blinds, high-reflecting blinds, hybrid light shelf and mirror light shelf) under two sky conditions (clear sky and overcast sky). In total, eight stimuli were captured and presented via stereoscopic images. Fifty participants evaluated the images using the semantic differential scale to rate nine architectural quality attributes. The results from MANOVA indicated that both the daylighting systems and the type of sky had an effect on the aesthetic attributes, and that the significant interaction effect suggested that the aesthetic perception of a daylighting system depends on the type of sky. Subsequent statistical findings showed that the high-reflecting blinds comprised the daylighting system that scored highest in nearly all attributes under both clear and overcast sky conditions.
