| Abstract |
This study explores the cognitive and psychological impacts of varying Levels of Detail (LoD) in architectural facades within virtual urban
environments to inform user-centered urban design. Unlike prior research focusing on LoD for design efficiency, this study examines its
neurophysiological effects through EEG. A VR environment with five LoD stages was created to simulate progressive facade complexity.
Forty-one adults experienced each stage using a Vive Pro 2 headset, while EEG data were recorded via the Emotiv EPOC+ system. Beta (13
?30 Hz) and alpha (8?12 Hz) wave activities were analyzed using Friedman and Wilcoxon tests. Results showed a significant increase in
beta activity and decrease in alpha activity from LoD1 to LoD2, especially in frontal and occipital regions, suggesting enhanced attention and
reduced relaxation. However, from LoD3 onward, neural responses became less significant or localized, implying possible cognitive overload
or adaptation. These findings indicate a nonlinear relationship between visual complexity and neural engagement, suggesting an optimal
threshold. The integration of VR and EEG offers a quantitative framework for evaluating spatial experience, supporting a neuroarchitectural
approach. The study proposes a shift from maximizing detail to achieving perceptual balance, emphasizing cognitive well-being in future
urban design. |
