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

Links

Summary

Using VR-based simulation with 27 participants exposed to 17 different lighting conditions, this study examined how illuminance and correlated color temperature jointly influence emotional responses and lighting preferences in a virtual office setting. Findings indicate that factors including illuminance level, CCT, presentation order, and participant demographics all meaningfully shape preferred lighting conditions, offering guidance for optimizing lighting design in workplaces and other environments.

Key Findings

27 participants were exposed to 17 distinct lighting conditions varying in illuminance and CCT in a randomized order within a virtual office environment.
Lighting preferences and emotional responses were significantly influenced by illuminance, CCT, order of presentation, and participant demographics.
User adjustment profiles revealed distinct preference clusters, suggesting that personalized or adaptive lighting systems may better serve diverse occupant needs.
