Surmised state of accommodation to stereoscopic three-dimensional images with binocular disparity
Article Abstract:
Accommodation exhibits a tendency to remain at the original image position, compared with convergence at the position of the reconstituted image, indicating an imbalance between the two. This was gleaned from a study of the state of accommodation to stereoscopic three-dimensional images with binocular disparity, where an image of a square was shown before the CRT screen (forward image) by the crossed visual-line method and behind the screen (backward image) by the non-crossed visual-line method. A comparison of the images with the original image on the CRT screen showed that the forward image looked smaller than the original, while the backward image looked larger.

Performance of 3-D digitizing in stereoscopic images
Article Abstract:
An examination of three-dimensional pointing in stereoscopic three-dimensional images found that it was difficult to identify the correct position of the image and that the image's depth was underestimated so that the object perceived by the observer was distorted. Observers who were familiar with viewing 3-D images made fewer errors in position and size perception than those with little experience in viewing such images. These findings suggest that 3-D pointing in stereoscopic 3-D images improves with experience, although accurate 3-D pointing is difficult to achieve.

A study on visual characteristics of binocular 3-D images
Article Abstract:
A comparison of the changes in the accommodation and pupil functions before and after observing binocular three-dimensional images as the visual distance varies was conducted for an ergonomic evaluation of the binocular 3-D image system. Findings indicate that the miosis and altering the focal depth offset the difference in the distance information on the accommodation and pupil functions. The visual functions are also believed to be stabilized at the dark focus, owing to the diminishing changes in the contraction and relaxation after observing the 3-D images.
