THE INFLUENCE OF CEILING SHAPE, SLOPE, AND HEIGHT IN VR SPACES ON IMPRESSION EVALUATION OF EXHIBITION ROOMS

This study uses HMD-based VR to evaluate how ceiling shape influences spatial impression and perceived volume in museum exhibition rooms. Sloped and barrel-vault ceilings were each modeled at three slope (25–45%) and height (4–6 m) levels, creating 18 conditions. Participants explored these via a Meta Quest Pro and rated 17 dimensions (e.g., openness, comfort) on a seven-point scale. Factor analysis extracted principal impression factors, and SEM quantified the impact of ceiling parameters. By sidestepping the limitations of physical setups, this VR approach offers evidence-based guidance for future museum ceiling design.
