Interactions Between Vibroacoustic Discomfort and Visual Stimuli: Comparison of Real, 3D and 360 Environments

The building industry and the design of interior environments are increasingly focusing on the user experience, incorporating sensory analysis to reconsider how office environments can be optimized. New immersive technologies offer significant opportunities for sensory science, enhancing our understanding of human perception and enabling the collection of multi-sensory data under controlled laboratory conditions. While the potential of Virtual Reality (VR) for these types of studies is well recognized, certain limitations still need to be addressed, including the lack of standardized research practices and the challenge of ensuring the simulated environment closely mirrors the real world. In this study, we compare 360° and 3D formats, to real-life settings in order to determine which format offers greater ecological validity for visual perception and immersion. Additionally, we examine the effects of vibroacoustic stimuli with different levels of intensity on perception and cognition of 30 participants. Subjective, physiological and cognitive data was collected throughout the test to tackle the participant's experience. This preliminary study introduces an immersive methodology that leverages advanced techniques to gain deeper insights into multisensory user experience in VR, marking a significant step forward in the optimization of VR for building evaluation.
