Study on Space Evaluation Using VR and AR

Abstract

This study examines the experience of architectural spaces and their evaluation using AR (augmented reality) and VR (virtual reality).We developed AR models of the Haus-hyazinth, the Row House in Sumiyoshi and the Farnsworth House. Using smartphones, users can perceive their structure and experience their internal spaces on real scale. By using these AR models, we carried out a space evaluation experiment among students who have studied these houses using drawings and photos. We presented two types of AR models: one with textures on their floors, walls, etc., and the other without textures. Then, we asked the students to examine and describe their perception of the space dimensions, largeness, ceiling heights, etc. Next, we developed a VR model of the Jiyu Gakuen Myonichikan. By using VR glasses, users can experience being inside the building. In a space evaluation experiment using this model, at first, we set up the examinee to visit the actual architecture; then, we presented a VR model, which allowed them to change the height, depth, and width of the space freely, to adjust the dimensions to the experienced space. Each of the three buildings have a small space, a single large space, and a space with varying ceiling height. We examined how the dimensions and the textures of the spaces are perceived through AR and VR models. We consider that AR and VR are not only tools for evaluating space, but also methods that complement the understanding of spatial characteristics. Needless to say, studying architectural spaces with the help of drawings and photographs is important. However, complementing this learning with spatial experience through AR and VR makes it easier to comprehend the characteristics of the space.
