We propose an automatic three-dimensional (3D) pupil tracking backlight system for holographic 3D display system with large image size and full-parallax accommodation effect. The proposed tracking module is applied to a holographic 3D display system with two sets of directional holographic imaging module composed of 2×2 large scale lens array and 22-inch high-resolution liquid crystal display 3...

We overview a previously reported head tracking integral imaging three-dimensional (3D) display to extend viewing angle accommodated to a viewer’s position without the crosstalk phenomenon. A head detection system is applied to obtain the head position and rotation of a viewer, and a new set of elemental images is then computed using the smart pseudoscopic-to-orthoscopic conversion (SPOC) metho...

We consider unitary SQCD, a three-dimensional \mathcal{N}=2

We are working for visual paring in these years. We have developed the series of visual parser generators, such as Eviss, VIC and Rainbow. They generate a spatial parser by defining the grammars of visual language. Using generated spatial parser, they can analyze the figures and can execute the specified actions. The GUI generator and the subset of VISPATCH are shown as examples. Also as a futu...

Spatial Transformations are the mental operations that users perform on graphs and visualizations in an effort to extract information that is not explicit. Unfortunately, previous research in the area of Spatial Transformations employed a statistically insignificant number of subject participants (e.g. astronomers, physicists, meteorologists, or undergraduate students). Although graph comprehen...

A powerful optimization method is proposed in this study for the minimal dimensional design problem of gearbox. It is a general model that is suitable to use for any series of gear drives system and can extract both dimensional and layout of components-limited optimization design together. The objective function in this study has many local extremes so for avoiding this situation, various const...

This paper presents a tile-based truly three-dimensional display system using a reconfigurable display matrix. The display surface is configured into a non-planar, discontinuous, and tile-wise shape according to the scene image’s depth information. Two prewarped scene images are projected onto the display matrix to account for projector occlusion. We describe the projector-based rendering proce...
