Assessing the Effects of Illuminance and Correlated Color Temperature on Emotional Responses and Lighting Preferences Using Virtual Reality

TL;DR

This study uses virtual reality to evaluate how different lighting conditions affect emotional responses and preferences, providing insights for optimizing lighting design based on user feedback and behavior.

Contribution

It introduces a novel VR-based method to assess human lighting preferences and emotional reactions under diverse illuminance and color temperature conditions.

Findings

Lighting preferences vary with illuminance and CCT.

Emotional responses are influenced by lighting conditions.

User adjustment behaviors provide valuable data for lighting optimization.

Abstract

This paper presents a novel approach to assessing human lighting adjustment behavior and preference in diverse lighting conditions through the evaluation of emotional feedback and behavioral data using VR. Participants (n= 27) were exposed to different lighting (n=17) conditions with different levels of illuminance and correlated color temperature (CCT) with a randomized order in a virtual office environment. Results from this study significantly advanced our understanding of preferred lighting conditions in virtual reality environments, influenced by a variety of factors such as illuminance, color temperature, order of presentation, and participant demographics. Through a comprehensive analysis of user adjustment profiles, we obtained insightful data that can guide the optimization of lighting design across various settings.
