This paper evaluates VR reproducibility found on the real-space screen, by performing some tests for space perception by means of different subject properties and presentation equipment to compare the images on VR and real space. This evaluation obtained the following conclusions. (1) The degree of space perception can be determined by whether one has architectural knowledge. Subjects with architectural knowledge can show a certain level of space perception during the first VR experience, while other subjects with no such knowledge can acquire the same space perception level as the well-versed subjects after they have repeated VR experiences. (2) The size of VR image displayed was insufficiently reproduced on the real space. Even a large projector used for this experiment, which was expected to achieve the highest reproducibility of the image size, left room for improvement by means of new image displaying approaches and other means. (3) Subjects showed completely different space perception between a large projector and a laptop computer for image display. The VR experience by a laptop computer was observed to be effective particularly for space perception.
