Influence of Subjective Impressions of a Space on Brightness Satisfaction: an Experimental Study in Virtual Reality

This paper investigates the relationship between participants’ satisfaction with brightnessand other key perceptual attributesof the sceneto gain insight in howuser satisfaction with brightnessis influencedby factorsother than brightness levels. In this study, a total of 100 participants were immersed in an office spaceusing virtual reality(VR). The brightness level in all immersive scenes were held constant while the office shading system’s design pattern, rendering materials,and furniture were varied to examine how different factors influence the participants’ satisfactionwith brightness. Statistical analyses indicate that there is a strong association between participants’ satisfaction withbrightness and other perceptual attributes. Additionally, while the effect of furniture on brightness satisfaction was not statistically significant,the analyses revealed that coloredmaterials had a significant effect on participants’ evaluations of their satisfaction withbrightness.
