In a three
dimensional v ision, as for the picture exhibited by a monitor or a screen, size and the aspect ratio of the images
are usually fixed. However, we think that scenes can be visually emphasized more by changing the presentation position of
an image, i.e., the position of a screen, or a viewing angle. In this research, we examined the displaying method that
Pseudo screen is placed in the S tereoscopic 3D (S3D) space. Pseudo screen induce changing the viewing distance
artificially. A nd pseudo screen itself displays S3D images . We verified whether the scene would be emphasized, in other
words , 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 pseudo
screen and surr ounding by the impression evaluation experiment
for students. At the second step, we displayed the visual stimulus, in which the position of pseudo screen changes with the
field of view of shots. These shots constituted a scene as montage. In the examinati on, we verified whether the stimulus
caused 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, in
the scene display examination, the shots constructed simple wireframe or plane are evaluated. Most participants
recognized that the position of the screen is changed, and “watching it nearby”.
As a result, we considered that chang
ing viewing distance caused by changing position of pseudo screen is effective for
emphasis of the scene.
