Investigating Environments' and Avatars' Effects on Thermal Perception in Virtual Reality to Reduce Energy Consumption

Abstract: Understanding thermal regulation and subjective perception of temperature is crucial for improving thermal comfort and human energy consumption in times of global warming. Previous work shows that an environment's color temperature affects the experienced temperature. As virtual reality (VR) enables visual immersion, recent work suggests that a VR scene's color temperature also affects experienced temperature. In addition, virtual avatars representing thermal cues influence users' thermal perception and even the body temperature. As immersive technology becomes increasingly prevalent in daily life, leveraging thermal cues to enhance thermal comfort - without relying on actual thermal energy - presents a promising opportunity. Understanding these effects is crucial for optimizing virtual experiences and promoting sustainable energy practices. Therefore, we propose three controlled experiments to learn more about thermal effects caused by virtual worlds and avatars.
