en: Analysis and fabrication for the dimensional expansion of arc 3D display to cone-shaped display

en: This paper successfully describes the analysis between 3D image location in air and arc-shaped scratches on cone-shaped arc 3D display. The arc 3D display is typically flat and its analysis has already appeared. However, when we would like to extend it to cone shape, the dimensional extension of analysis should be necessary, since the lack of adequate analysis increases the approximation error of the 3D image location. In this paper, we discuss the three-dimensional analysis for cone-shaped arc 3D display. In addition, we describe the actual fabrication of a cone-shaped arc 3D display and show that the 3D image can be displayed similarly with the analysis.

en: Realism of Dome Videos across Dome Shapes and Screen Illuminances --- A Case of the Dome Video Screening about the Mega Sport Event

ja: ドーム形状とスクリーン照度の違いから見たドーム映像の臨場感 --- メガスポーツイベントのドーム映像上映を事例として

en: The purpose of this study was to compare and verify the effects of differences in specifications among domes on the realism of dome image. Until now, there has been little research on how external factors affect the realism of dome image. This was because the equipment used to show dome image is proprietary, and it has been very difficult to show the same content with the same specification at all planetariums at the same time. In this study, we cooperated with the``Immersive LIVE Viewing'' project of Tokyo 2020 live distribution of the Olympic Games, and conducted a questionnaire survey to analyze the relationship between the audience's impression evaluation and external factors when viewing sport video. These results suggested that the dome tilt had no effect on the sense of presence, the smaller the dome diameter, the more `feeling good' and `powerful', and the higher the screen illuminance, the higher the sense of presence evaluation and the higher the clarity of the images. After the further verification, we believe that a high sense of presence through dome image may become important as one of methods of virtual tourism.
