Exploring the relationship between library reading space height and user perception: A physiological and subjective analysis

Abstract

As a central functional aspect, the design of library reading spaces should consider users' perceptual experiences to optimize their psychological responses. However, the current literature lacks a rational analysis and definitive guidelines regarding the interior height design of reading rooms. This study focuses on physiological data supplemented by subjective evaluations to explore potential correlations between library reading space height and user perceptions. Specifically, we employed Virtual Reality (VR) to create four experimental scenarios, investigating reading space heights within a laboratory setting while capturing corresponding electroencephalogram (EEG), galvanic skin response (GSR), and subjective assessment data. Correlation analysis of EEG signals and height variations across the four scenarios revealed that the exposure sequence influenced participants' physiological experiences, particularly in the frontal lobe. Fitting curves illustrated changes in α and βH as heights varied, influenced by scene disparities. Correlational analysis between physiological and survey data established a connection between psychological perceptions and α waves. Findings indicate that height variations impact both physiological and psychological aspects. For a reading room space of 12.600 m × 22.500 m, maintaining psychological and physiological comfort requires a minimum height of 2.600 m. This research contributes a unique perspective by constructing a framework for investigating library reading spaces, offering novel insights for optimizing their design.
