A comparative study on spatial perception in real and virtual office environments under different lighting conditions
(2019-01) Kuş, Büşra
The aim of study iş to conduct a comparison between real and virtual environments from the spatial point of view under different lighting conditions. In this study, visually same office environments were created in real environment (RE) as well as in virtual environments (VE) in order to be able to observe only the perception between the two environments. The experiment was conducted in full-scale office environment and virtual environment by using Unity 3D program with participating of sixty people. These environments were appraised under 4000K (cool white light) and 6500K (daylight) lighting color temperatures. An office room in Bilkent University and Environmental Design building was used to carry out the experiments. The participants were asked to experience the environments firstly, later on they were as requested to answer the previously prepared questionnaire with semantic differential scale. As a result of this study one can say that the perceptions of both environments RE and VE were similar to some extend in more than half of the 12 adjective pairs under both color temperature. Adjectives such as usual-unusual, dynamic-static, spacious-confined and harmonious-discord demonstrated significant differences for both environments. Moreover, participants perceived real environment more spacious, usual, harmonious and less dynamic than virtual environment under both lighting conditions. Only the functional-nonfunctional and formal-informal adjective pairs behaved significantly different under 4000K and 6500K respectively. There were no significant effects of color temperatures in real and virtual environments.

A review of spatial auditory scene assessment approaches
(2022-08) Golubkova, Kristina
The state-of-the-art research in sound technologies is now increasingly focused on augmented reality systems, which use spatial auditory content to represent information beyond that encountered in the real world. Successful implementation of spatial sound on such a large scale requires comprehensive and reliable research data in acoustics, cognition, and the principle of auditory processing. The main contribution of Rumsey's scene-based paradigm is a theoretical framework for the description and analysis of space-related scenes. This thesis presents an overview of the existing research related to the perception of spatial sound within three domains: spatial hearing and cognition, spatialisation, and evaluation of spatial quality attributes.
