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.

This paper focused on the reliability of the virtual simulation system for the residential environment evaluation. Through the comparative experiments between virtual and actual space, brightness perception, space perception, length perception and a sense of reality were examined. In the virtual space the height and the width were well reproduced, while the depth could not be perceived so precisely. A sense of reality was influenced by the level of modeling and the way of texture maping, and it was found out that the level of modeling does not need to be unlimitedly raised up to get a high degree of reality.

The purpose of this study is to investigate the behavior of biomass gasification in the packed-bed, conducting gasification experiment and analysis of syn-gas in the reactor. In this study, pellets of black pine (ψ6.5mm×8.5mm) are fed intermittently with air as the gasification agent. The gasification experiments were carried out by two type gasification methods, such as updraft and downdraft setups. In the gasification tests, the temperature distribution in the gasification reactor and the gas compositions are measured and analyzed during gasification by thermo-couples inserted from a furnace wall and a micro gas chromatograph, respectively. Product gas before cooling were sampled for determine the amount of tar generation.
