摘要：In a threedimensional v ision, as for the picture exhibited by a monitor or a screen, size and the aspect ratio of the imagesare usually fixed. However, we think that scenes can be visually emphasized more by changing the presentation position ofan image, i.e., the position of a screen, or a viewing angle. In this research, we examined the displaying method thatPseudo screen is placed in the S tereoscopic 3D (S3D) space. Pseudo screen induce changing the viewing distanceartificially. A nd pseudo screen itself displays S3D images . We verified whether the scene would be emphasized, in otherwords , the sense of “watching it The prior study or displaying method about previously described are uncommon.As a first step, we evaluated visual pattern of the pseudoscreen and surr ounding by the impression evaluation experimentfor students. At the second step, we displayed the visual stimulus, in which the position of pseudo screen changes with thefield of view of shots. These shots constituted a scene as montage. In the examinati on, we verified whether the stimuluscaused change of viewing distance, emphasis of the scene, and is recognized as montage. Regarding the pattern evaluation,the images that wireframe or plane is extended from edge of the pseudo screen are suitable for th e display method. And, inthe scene display examination, the shots constructed simple wireframe or plane are evaluated. Most participantsrecognized that the position of the screen is changed, and “watching it nearby”.As a result, we considered that changing viewing distance caused by changing position of pseudo screen is effective foremphasis of the scene.
