There are several researches on 2D gaze tracking techniques for the 2D screen for the Human-Computer Interaction. However, the researches for the gaze-based interaction to the stereo images or contents are not reported. The 3D display techniques are emerging now for the reality service. Moreover, the 3D interaction techniques are much more needed in the 3D contents service environments. This paper addresses gaze-based 3D interaction techniques on stereo display, such as parallax barrier or lenticular stereo display. This paper presents our researches on 3D gaze estimation and gaze-based interaction to stereo display.

본 논문은 포인터 레이저를 이용한 3D 스캔방식을 제안한다. 3D 스캔이란 물체의 3차원 정보(x, y, z)를 추정하는 기술이다. 3D 스캔 기술은 과거에서부터 많은 연구가 진행 되었으며 스테레오 카메라, 패턴 인식 등 다양한 방식으로 3파원 정보를 추정 한다. 기존의 방식들은 물체의 표면 정보를 정확하게 스캔하는 장점을 가졌지만, 스캐너의 비용이 비싸고, 그 부피가 크다는 단점 때문에 상용화에 어려움이 많다. 본 논문은 기존 방법보다 부피가 작고 가벼우며 시스템 비용이 적은 포인터 레이저를 이용하여 3차원 정보를 추정하는 방법에 대하여 설명한다. 물체의 깊이 정보(z)에 따른 포인터 레이저의 영상에서의 위치 변화를 통하는 방식으로 3차원 정보 추정을 구현 하였다. 실험을 통하여 포인터 레이저만으로 3차원 정보가 추정 되는 것을 확인한다. 위 방법은 3D 스캐너의 부피가 최소화 되므로 다양한 제품에 부착되어 3D 스캐너의 상용화를 기대한다.

Recently, media art is transforming from analogue to 'digital', and from 2D to '3D'. In particular, the range of utilizing 3D Media Art is getting wider through merging with other genres of contents in the digital environments, such as Media façade, Hologram, Virtual reality, App application, and etc. Therefore, by referring to the 3D award-winning works of Pirx Ars Electronica, which are regarded as the most outstanding works of media art of today, factors that affect sensation of visual immersion have been analyzed, through which strategies for maximizing viewers' interests in media arts and heightening their emotions while viewing have been determined. Based on the findings of the study, it has been shown that such works of media arts that involve development of concepts with 'creativity' and 'variability' from the perspective of visual concept, such as 3D modeling and mapping, with 'consistency' through out all concepts, as well as the works with stronger 'restriction' of concept within its animation and postproduction, attracted more interests from the viewer. From the point of view with visual four steps in composition, positioning the change in quality of 3D 'shape' and 'material' following the four-step rule, and gradual increase of change in quantity within the 'number' and 'size', in addition to increased degree of systematization within the change in editing, such as the 'scene change', resulted in more heightened emotions from the viewer. Thus, in order to maximize sensation of visual immersion, strategies for 'developing 3D visual concepts' while 'synchronizing' them, as well as 'strengthening the four steps within 3D visual composition' while 'systematizing' them should be emphasized.

A new configuration of LCD projectors for polarized stereoscopic projection having no light loss in the polarization process is suggested. In the proposed system, two polarizing filters that are employed in the conventional LCD polarized stereoscopic projection system causing additional light loss and image distortion are excluded by taking into account of polarization property of the LCD projector and image processing techniques. From some experimental results by using the Type-1 LCD projectors, light loss of the proposed system occurring in the polarization process is found to be zero.

In this paper, a new multi-view 3D video communication system for real-time Reality teleconferencing application is proposed by usin gthe IEEE 1394 digital cameras, Intel Xeon server computer system and Microsoft's DirectShow programming library and its performance is analyzed in terms of image-grabbing frame rate and number of views. The captured two-view image data is compressed by extraction of disparity data between them and transmitted to another client system through the communication network, in which multi-view could be synthesized with this received 2-view data using the intermediate view reconstruction technique and displayed on the multi-view 3D display system. From some experimental results, it is found that the proposed system can display 16-view 3D images with a gray of 8bits and a frame rate of 15fps.
