The authors have found a phenomenon in which the blinking speed appears to be faster when the beta motion is viewed in peripheral view. In this paper, we focused on the beta motion on the circle and conducted an experiment on how it looks in peripheral vision. As a result of the experiment, it is understood that the speed increases as the retinal eccentricity increases regardless of the annular ring size. In addition, it became clear that as the retinal eccentricity in the horizontal direction increases, the apparent shape of the beta motion tends to change from the annular ring shape.

We described the evaluation method of stereoscopic images by using perspective images with continuity that is easy to feel a depth in 2D images. In this paper, we propose a new 3D evaluation method, using reversed images and an evaluation item of an incongruity. As a result, in terms of the perspective image, we got the effectiveness of the evaluation item “incongruity” in three evaluation items of depth feeling, stereoscopic feeling, incongruity.

The h-Index is frequently used to evaluate researchers. However, the index is not suitable for young researchers because they typically have only a few prior achievements. In this paper, we evaluate the potential of JSPS research fellows using the h-index and the betweenness centrality of co-author networks. The results show that the new measure appropriately evaluates the potential of young researchers at their early stage, as compared with the h-index.

The following three visual phenomena have been confirmed as a visual effect occurring at an edge having a density change: (a) Mach band, (b) Chevreul illusion, and (c) the Craik-O'Brien-Cornsweet effect. These are considered to be different phenomena. In our previous research, it was found that by varying the blurred edge width the density value of the image changed and the contrast decreased approximately by 20% at the maximum. From this phenomenon, it was possible to explain to some extent the relevance of the above three phenomena by the edge width. Furthermore, under the research of gazing time and edge blurring phenomenon, we confirmed that edges disappear with low contrast. In this paper, we focus attention on the gazing time and conduct an evaluation experiment on how much the Troxler effect occurs, using the density difference of the presented image as a parameter. We also investigate the evaluation of the Mach band at that time. Through these experiments, it is possible to show the experimental results that clarify the relationship between the four phenomena.

We propose a new autostereoscopic display system employing an eye-position tracking technique for multi-viewers, who do not need to wear 3-D glasses. We also describe the developed stereoscopic projectors and the lenticular screen design for this system. In this system, the 3-D screen consists of two lenticular screens and a diffusion layer. Each 3-D projector which corresponds to a viewer consists of two projectors for right and left images. The viewer's positionsare detected, and the 3-D projector moves according to the viewer's movement. 1. INTRODUCTION We are conducting basic research on a virtual space teleconferencing system [1] that achieves a sense of reality. Such a system needs large-scale stereoscopic displays. Stereoscopic displaytechniques requiring special glasses cause users to feel uncomfortable and tired, and reduce thefeeling of naturalness. In the field of teleconferencing, a no-glasses technique using a lenticularscreen was found to be superior to holography and a volume-scanning-type 3-D display in terms of

In this paper, we propose a new autostereoscopic display system employing an eye-position tracking technique. In this display system, the observable area of stereoscopic images becomes wide and an autostereoscopic display is realized by combining the tracking technique with computer graphic images. The wide 70-inch lenticular screen and HDTV LCD-projector generate more impressive 3-D images than conventional system.

We describe a real-time animation technique to generate blinking and gaze shift, while still considering convergence, using a Graphic Workstation. Moreover, we evaluate the feeling of eye contact using this eye animation. In our experiment, we subjectively evaluate gaze generated by CG using 2-D or 3-D display, and compare it with the gaze of an actual person. We also perform an experiment on the time required for perception of eye contact when the eyes of the CG image are moving.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
