Impact of Correlated Color Temperature on Visitors’ Perception and Preference in Virtual Reality Museum Exhibitions

Abstract

From the perspective of psychophysiological evaluation, this paper provides a theoretical reference for the lighting settings of museums. In order to study the impact of correlated color temperature (CCT) on visitors’ perception and preference in museum exhibitions, an experiment was conducted in the ergonomics laboratory of Nanjing Forestry University. We invited 50 participants to visit the virtual reality museum exhibitions with different CCTs, built by Autodesk 3D’s Max 2017. Specific psychophysiology variables—eye movement, electrodermal activity (EDA), and heart rate variability (HRV)—and the perception and preference of participants were collected. The results indicated that the association of CCT with eye movement, HRV, and some perceptual dimensions was significant. Under high illumination conditions with different CCTs, the pupil diameter and warmth decreased with the increase in CCT, but the comfort and pleasure scores increased first and then decreased. The CCT scenes sorted by LF/HF ratio from high to low were 4500 K, 6000 K, and 3000 K, which was consistent with the results of preference ranking. The LF/HF ratio showed significant sex differences and major discrepancies.

A Study of the Emotional Impact of Interior Lighting Color in Rural Bed and Breakfast Space Design

“…Therefore, Moriyama et al studied the effects of colored lighting conditions on human cognitive abilities and found that most elderly people showed greater improvements in emotional cognition under different colored lighting conditions [38]. Na Yu studied the effects of correlated color temperature (CCT) in museums on visitors' perceptions and preferences in museum exhibitions and found that the correlated color temperature (CCT) correlated significantly with eye movements, heart rate variability (HRV) and a number of perceptual dimensions [39]. The correlation was significant [39].…”

Tiina Rosenqvist found that the main function of human color vision is to enhance the manifestation of some relevant abilities and that vision can be adapted to and interpreted by the brain for a wide variety of color perception phenomena [40].…”

Deep Convolutional Attention based Bidirectional Recurrent Neural Network for Measuring Correlated Colour Temperature from RGB images

“…A digital picture comprises RGB (red, green and blue) standards ranging from 0 to 255 allocated to each pixel (in the case of a white and black image, the pixels are assigned grey values ranging from 0 to 255). The colour of the influencing light is displayed in a scene's correlating colour temperature (CCT), which is measured in Kelvin (K)) [2]. The CCT value can be used to determine how an object will appear in an image.…”
