CONFERENCE PROCEEDINGS FREE ACCESSHigh resolution three-dimensional(3D)display is difficult to obtain in the conventional methods without using any special glasses because of each multi-view images is displayed on the different pixels on the panel. Then, we proposed a new method to solve this problem. In this method, the light from a back-light is controlled in the required direction, and the corresponding images are displayed on liquid crystal display(LCD)in synchronized with the light direction. In this paper, the display principle, a design concept and property of the prototype 3D display are described.View full abstractDownload PDF (788K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, we describe some results of our study on new telecom smelling services based on experimental devices diffusing scents over networks. Usability tests carried out on the basis of two prototypes, show that adding a third sense to the existing senses available in multimedia services has a strong positive impact but requires new approach in the service design process. Since the business of scents is increasing (presonal and home fragrance, brand's smelling signature for corporate communication...), telecom applications using scents devices are broad and may address companies, professional communities as well as individuals.View full abstractDownload PDF (308K) -

CONFERENCE PROCEEDINGS FREE ACCESSHyper-realistic display that has wide field of view and high resolution is desired. Current blending system needs much time to setup, and is difficult to apply to curved screen system. We propose new blending technique using a digital camera to calibrate the geometry and color difference. The calibration is fast, accurate and is easy to setup. We apply this technique to high resolution projection system with 6 million pixels.View full abstractDownload PDF (1275K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, we discuss the development of wearable systems which we collectively term VizWear. Vision plays an important role in both people's and computers' understanding of contextual information, and the use of augmented reality(AR)techniques is a good way to show information intuitively. This is the basis of our research on wearable systems and services based on CV and AR techniques. Our wearable systems enable us to run different multiple tasks in real-time. In this paper, we introduce four component functions implemented on the wearable systems.View full abstractDownload PDF (1369K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe sense of immersion in appreciating images is not only realized by technical achievement but also greatly influenced by the human factors. Besides the physiological or cognitive factors, the content of the images plays a key role, including the way the content is either relevant or not to the contemporary culture and society. The sense of reality toward certain contents or themes would change in the society. In the history of visual entertainment, successful systems or contents respected such elements. Today in our information society, the seamless connection between the image appliances and communication tools has blurred the boundary between the real and the unreal. In such a situation, the role and possibility of digital art and its positive influence on technology are greater than ever, as bridging between real and unreal, focusing on human factors has been always the essential deal of art.View full abstractDownload PDF (614K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe introduce our project for recording and communicating multiple videos in a large-scale space such as a convention hall or a succor stadium. By seamlessly integrating the multiple 2D videos and the 3D models reconstructed from the 2D, the observer can select an arbitrary viewing position and can see a video with motion parallax. The quality of the synthesized video at a novel viewing position can be improved by combining the texture obtained by pan-tilt-zoom control cameras with the 3D model reconstructed from the videos captured by the fixed cameras. Our system can record completely synchronized multiple videos with an identical timestamp for every frame captured at a sane instant. An experimental approach we adopted in this project has successfully clarified a lot of useful techniques such as the camera calibration and the camera arrangement in a large-scale space.View full abstractDownload PDF (1309K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn order to design a video communication systems that can embody participants' behaviors, we defined five requirements i.e. 1) arrangement of bodies and tools requirement, 2) orientation of bodies requirement, 3) hand gesture requirement, 4) mutual monitoring requirement, and 5) sequential organization requirement. We named virtual spaces generated by video communication systems that support these requirements as "embodied spaces". In order to realize the embodied spaces, we propose a design guideline named "body metaphor". Then we introduce Agora, GestureMan, and Digital but Physical Surrogates to show how the guideline can be used to design embodied spaces.View full abstractDownload PDF (1074K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have discovered a new 3-D display method which needs only two conventional 2-D displays and a half mirror without any extra equipment. We have developed a prototype 3-D display(28 inches diagonally and 60cm deep)by applying this method to several pair of planes. The method enables an observer to perceive an apparent 3-D image of continuous depth when the 2-D displays are positioned at different depths, and their luminances are divided between them according to the 3-D image depth. We have also found an extension of this method, in which a DFD image can be perceived as an image protruding outside the region between the two displays when the two display images have opposite signs of luminance difference between an object and the surroundings.View full abstractDownload PDF (1068K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have been researching Super Multi-View 3-D display which enables natural 3-D display using multi-perspective image with fine perspective-pitch, which is narrower than the pupil diameter of viewer's eyes. It is difficult to develop Super Multi-View 3-D display with commercially available device because Super Multi-View 3-D display has to display many parallax images. To overcome the difficulty, it is effective to introduce an eye-position detection system into Super Multi-View 3-D display. We have developed an eye-position detection system that is suitable for Super Multi-View 3-D display.View full abstractDownload PDF (915K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have been studying a field-sequential stereoscopic display with Hi-Vision PDP. We have already proposed light emission scheme for stereoscopic display and processing for improvement of gray scale expression in stereoscopic displaying. The effectiveness of the proposed method was confirmed by computer simulation. However, further improvement of the cross-talk impairment was necessary. We have developed a signal processing unit and a stereoscopic display with a 50-inch PDP. Cross-talk impairment between left and right images is significantly reduced by a combination of new phosphors with shorter decay time and a cross-talk canceler. The developed display reproduces impressive stereoscopic Hi-Vision images on a 50-inch wide screen with high picture quality.View full abstractDownload PDF (884K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe authors proposed an ultra-high definition image format(QHD:Quadruple HD), which provides double the resolution of HDTV image format in both lengthwise and crosswise. Based on this format, we developed QHD camera, which captures each color of RGB by single chip, and QHD projector, which displays each color of RGB by single chip. In this paper, we would like to describe the outline of QHD projector, and the outline and the result of a subjectivity evaluation experiment of the QHD image carried out using the still-frame pictureView full abstractDownload PDF (630K) -
