研究室紹介
Professor Kyung-Ah Choi's research lab specializes in the psychological and emotional impact of environmental design, particularly focusing on materiality, lighting, and spatial configuration in architectural and immersive environments. The lab investigates how sensory and perceptual factors—such as material texture, color temperature, lighting placement, and spatialization—shape human emotional responses and spatial perception in both physical and virtual settings. Current research spans exhibition design, virtual reality storytelling, theatrical lighting, and residential interior perception, with an emphasis on creating emotionally engaging and human-centered spaces. The lab employs virtual reality and physiological data (e.g., ECG) to empirically evaluate design interventions.

4Understanding the impact of material choice and lighting in exhibition spaces is crucial for enhancing visitor experience and emotional engagement. This study explores the influence of material, lighting color temperature, and lighting type on emotional responses in exhibition environments. Utilizing four materials (marble, metal, wood, plaster) and combinations of two lighting color temperatures (3500K, 5000K) and two lighting types (diffuse, spotlight), 16 virtual exhibition spaces were create
This study examined the effects of stage lighting color combinations and placement on audience spatial perception and emotional responses. A virtual stage was constructed based on an existing musical theater, and four lighting colors—red, yellow, green, and blue—were combined into six two-color combinations. Each combination was arranged by varying the placement of the two colors as key light and back light, resulting in twelve lighting conditions. A total of 100 participants experienced six ran
This study investigates how spatialization strategies shape literary immersion in virtual reality (VR). While immersive media have been widely adopted in education, healthcare, and cultural content, research on literary VR has largely attributed immersion to the medium itself, leaving the role of spatial design insufficiently examined. To address this gap, the study explores how spatialization strategies influence user experience when literary texts are translated into virtual environments, with
Exposed concrete is widely used in commercial spaces for its aesthetic appeal, durability, and energy efficiency, yet it is often perceived as cold and uninviting in residential settings. This study explores design strategies to improve emotional perceptions of exposed concrete in residential spaces by examining the effects of surface color and texture image. Virtual residential environments were created by combining two surface colors (warm and cool) and two textures (rough and smooth). A total
