(Summary) 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.

Academic Paper (Unrefereed Paper):

1.	小柴恵一, Kenji Yamamoto, 伊藤央二 and 尾久土正己 : Realism of Dome Videos across Dome Shapes and Screen Illuminances, --- A Case of the Dome Video Screening about the Mega Sport Event ---, 観光学, 27, 1-9, 2022. (Summary) 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.

(Summary) Arc 3D display is one of the methods for presenting stereoscopic images to realize smooth motion parallax.This technology is conventionally used for flat displays, but this paper tries to expand it for cone-shaped displays. In this paper, the analysis of the position of the three-dimensional image generated by a cone-shaped Arc 3D display is discussed and is confirmed by the experiments using an actual cone-shaped Arc 3D display.

(Summary) Hand reaching action can successfully reduce the perceived depth instability of aerial images. Moreover, hand reaching action with stick held by hand can also reduce instability. This indicates that perceived depths by only visual information and hand reaching action have different process in human brain.

(Summary) Arc 3D display with moving head or moving Arc 3D display can successfully solve the perceived-depth sticking problem to real object surface in front of designed distant 3D image, although stereoscopic display cannot solve the sticking problem. This is because continuous motion parallax is satisfied in Arc 3D display but not in stereoscopic display, which is effective to perceive the designed depth.

(Summary) We proposed and developed a new Arc-3D-image rewriting method utilizing Frestnel structure. To solve unselectivity problem in Arc-shaped scratches, we utilize Fresnel structure for packing Arc-shaped scratches into compact-vertical rectangle region without unselectivity in Arc 3D display. Pixel arrangement method with almost same aspect ratio are proposed and developed. (Keyword) Arc-3D / Fresnel Arc-3D / Rewriting image pixel arrangement / Automatic generation

(Summary) ステレオ画像において書き割り効果が見られる被験者に対して運動視差を付加したところ，書き割り効果の改善が見られた．書き割り効果は本来の物体の厚みを過小評価してしまうステレオ画像特有の知覚の歪みの一つであり，撮影距離と観察距離の乖離が大きくなるほど起こりやすい．本研究では，様々な距離から撮影した日常的で自然なシーンのステレオ画像において発生する書き割り効果に対して，運動視差を与えることによりそれが低減するかどうかを評価した． (Keyword) 書き割り効果 / 運動視差 / 撮影距離 / 観察距離

(Summary) We propose a high-security display that uses DFD displays with fuzzy depth or color distribution and brain completion to prevent peeping even with computer analysis. This high-security display provides information only to humans and successfully prevents recognition by peeping eyes and camera shots.

(Summary) 手や道具を空中像に伸ばしていくハンドリーチング法による奥行き知覚の改善法を提案し，視覚情報のみによる空中像の奥行き知覚の不安定性をほぼ抑制できることを明らかにした．具体的には視覚情報のみで空中像を見たとき，実際に表示している位置よりもレンズ側に約 10cm の位置を知覚していたのに対して，手と道具を持った状態のどちらの場合においてもハンドリーチング法を用いるとはレンズ側に 0cm から 4cm 程度の位置を知覚し，不安定性が軽減に成功した．
