    We present in this paper a method of switching between past and present photographs seamlessly which tackles a certain problem: requisition of present photograph at the same position where anyone took a photo in the past. We first describe estimation of past position to take a present photo at the same position. After that we describe interpolating the two images to make seamless switching. Finally, we performed assessment experiments with simulation or using this system. Consequently, it appeared that our system can make seamless switching in 90% success rate.

    Sand Animation is names of an art technique for producing animation work with sand and a performance art of the production process. Sand Animation can produce a unique warmth expression such as sepia tone by using sands and a light; however, because production and preservation of a work are difficult, it is not easy for the beginners to experience it. In this study, we develop a paint tool for image generation of Sand Animation style. We provide a production environment near the production of the work in reality by realizing an expression of a local change of sands on Sand Animation, and adopting a multi touch screen as an interface.

    Recently, decrease in physical strength and lifestyle diseases caused by lack of exercise becomes a problem. For those solutions, various exercise machines which people can use easily in a room are available. But, it was difficult to get enough effects from exercise. Therefore, fitness machines with automatic controls are developed so that people can exercise efficiently, and exercise programs are designed with game elements to encourage regular exercise. However, there were problems that monotonous exercise makes it difficult for people to experience a sense of accomplishment, and if the degree of difficulty of the game is not set properly, people cannot perform the appropriate amount of exercise. Then we propose a game which supports physical exercise. This game helps a user do exercise effectively by adjusting gameplay based on player's heart rate dynamically.

    Recently, a trend has developed to restore traditional Japanese buildings such as theaters as symbols of town renovation. However, the restoration of such buildings commonly encounters many difficulties such as a lack of documents, and different construction materials and structures between the old era and the present. Thus, virtual images of a restored building should be a great help in evaluating and discussing various restoration plans. Therefore, we have constructed a theater restoration support system using virtual environments to help with the design plan for indoor restoration of an old theater in the Saitama Prefecture of Japan. CAD data based on actual measurements were employed to construct the 3D model for the system, which ensures reproduction of the interior details of the theater.

    We are proposing the IllusionHole system, which allows three or more moving people to simultaneously observe individual stereoscopic image pairs from their own viewpoints. With a simple configuration, it provides intelligible 3D stereoscopic images free of flicker and distortion. Based on the idea of the IllusionHole, a prototype is established with two short throw DLP projectors and polarization filters. Since the prototype has no obstacles on the chassis, every side has an equal capability of being used to observe 3D objects. This paper describes details of the prototype.

    These days, new types of display have been proposed as new technologies and ideas for interface developed, igniting discussions on what should be the shape of ideal display. We propose Bloxels, our new concept of display whose physical shape can be grasped and created by human so that people could have more intuitive access to information by taking advantage of physical reality of blocks. A Bloxel is a translucent cubical block that glows in full color according to the transmitted data from the neighboring Bloxel, and works as a volumetric pixel when a user stacks hundreds of Bloxels to build displays with a variety of shapes.

    We have proposed "Controllable Particle Display", that controls the position and blinking pattern of particle and yields the visual representation and the representation to touch these particles. Additionally, as one of example of implementation, we use water drop as the particle of "Controllable Particle Display". In this method, the system represents the objects by projecting the images to the falling water drops according to the position of water drops from the directly below. However, this method has the problem in terms of the brightness of object. In this report, we propose the method that image are projected to falling water drops at an angle, and users watch the image of this display from an anterior view of projector. By setting several projectors at several points, users can see the anterior view of one of a projector from each direction.

    A lot of indoor positioning systems are studied to offer a public service based on one's position information. We have studied the indoor localization system using fiducial markers. You can design the markers as you like so they are usable as interior decoration. In this system, you can get three-dimensional position and pose of your camera by capturing the image of the markers arranged on the floor. But there are some problems to use this system in the public space. For example, the decline of the marker recognition rate by the change of the surrounding light condition, and the instability of the marker recognition rate according to the kind of the marker and the camera angle. In this research, we achieved the robustness enhancement of the system in the public space and increased recognizable markers.

    Recently, it became possible to easily produce interactive contents by the help of development environments, such as Flash. Produced contents utilize audio-visual effects in an efficient way. Haptic devices, on the other hand, enabled production of interactive contents by adding the sense of touch into them. Considering the benefits of both approaches, we developed a highly interactive language learning system by combining Flash with a haptic device, called SPIDAR. The system is called as INSTILL and evaluated on a learning-experiment. Experiment results suggested that combination of Flash and SPIDAR made a major contribution to the subject concentration.

    This paper describes the characteristics of haptic sensation that is evoked at the finger skin by a shear force presented using rotational contactors. The tactile sensation scaling was performed regarding five contactor conditions and directions of rotation. Approximately six to eight levels were discriminated in the given 100-to-1500rpm range at the index finger. The sensitivity difference among stimulation sites was investigated; the result showed the highest sensitivity was observed at the fingertip. The interference between two shear stimulations was measured to show the masking effect. The results demonstrated that the sensitivity decreased with the increase of the intensity level provided by an adjacent contactor.

    Rain changes its complexion based on the time and the place. Each aspect of rain provides a unique impression, so experiencing it in distant places and different times would be a new way of sharing information. To represent rain, we focused on an umbrella as a user interface to connect humans and rain. Generally, people experience rain with sounds, sights, or sometimes smells; however, in our proposed system, we exploit the vibration perceived through an umbrella's handle to let people feel the rain. With Funbrella, you will find how many complexions rain has because it gives you opportunities to feel and enjoy various kinds of rain that is recorded as real vibration data with itself.

    I researched methods of analyzing and organizing "Lifelog Information". The concept of Lifelogs, which has recently become popular in the field of infomation technology, involves recording everyday life by using a wearable device which contains a camera, microphone, and GPS sensor, and using the collected data to help human memory and human activity. However, when we keep recording for some months or years, we can accumlate too much data to manage easily. Therefore, we must analyze and separate the data into important scenes. This makes it simpler to search for and retrieve specific data. In my research, I used image analysis to extract images that contained human faces from several hundred thousand pictures I collected in my Lifelog recorder. Thorough this method, I was able to construct a system to extract only those scenes where I had met with people.

    The downsizing of computers and sensors has made it possible for people to easily carry a computer with them during their daily lives. The data related to user's life experiences is called "lifelog" and it can easily be collected these days. Although lifelog research has been conducted for a long time, its application is still under development. In our research, we aimed at structuring of a lifelog for the purpose of the application such as tools to recall memories. We actually captured lifelog data with a device that has multiple sensors, and we estimated the participants' activities. Moreover, we efficiently showed the estimated results on the viewer we created. Finally, we verified the effectiveness of the research in several tests.

    It is imperative to watch movies more efficiently, because the number of movies on the internet increases to the extent that we cannot treat. Using a large screen display is one way to deal with those large numbers of information. When it comes to a large screen display, the guide where to watch is required. Hence we verified the effectiveness of attention attractors in a large screen display. Next we extracted some scene to which many users pay attention from log data of a Japanese video portal website.

    Recently, with the expansion of digital devices with high storage capacity and high-speed Internet, there is a need for user interfaces that allow easy and comfortable browsing of large amounts of related data. We propose a user interface that allows the user to "take a stroll" through large data sets, by displaying focused data and related data in a way that makes it easy for the user to recognize their desired information within the data set. In this paper we first describe the problems with existing technology, then propose a design that effectively allows for "taking a stroll" through information on the screen, using novel methods involving radial and sector zoom, and lines that demarcate degrees of relatedness of information. The above-mentioned method is applied to a television program guide and described as a prototype, and the results of an evaluation by usability experts are described.

    In the field of life log system to record personal experience, the characteristics of sensor data have to be considered for the evaluation of retrieval. To evaluate our system which records personal photos with scent data and extracts feature points based on scent data, a novel method is needed with consideration of characteristic of scent data like time lag of spread in the air. In this paper, we evaluate our system by demanding correlation between sensor response and user response based on the results of preliminary experiment which records human response of scent. The result shows that our system is effective than uniform distribution or same value to retrieve the change of scent.

    A Projection-based olfactory display that uses an air cannon allows us to deliver smells locally, both spatially and temporally. This device can deliver smells to a specific user, without letting other people notice smells. However, the tails accompanied by vortex rings cause undesired smell diffusion, which reduces the performance of smell localization. In this paper, we examined effects of the actuation parameters of an air cannon on the behavior of a vortex ring and its tail, using computer fluid simulation.

    Gustatory sensation is based on chemical signals whereas the visual sensation and auditory sensation are based on physical signals. Therefore there are few studies on gustatory display. In our research, we aim at the realization of gustatory display and propose the method to present tastes by using the influence that visual feedback gives to gustatory sensation. By this report, we report about two fundamental experiments to evaluate the influence that the color of the drink gives to recognition of the taste.

    The dynamic characteristics of the virtual system are discussed for the medical application. The internal organs synthesized by visco-elasto-plastic materials have interactions in consideration of their distortion and destruction caused by virtual tools. The operation of blood vessel by a thin plate-like and a hollow-cylindrical object with oblique edge were synthesized as a knife and a blood needle, respectively. The motion of the virtual tools in twist, rotation or parallel movement was also examined on their operation of virtual tissues and organs.

    The purpose of this study is finding out the artisans' implicit knowledge by exploring their inner state. Finding out the secrets is important for skill training, which is in critical situation in this aging society. Especially, Kirigane, Japanese traditional art, needs successors who have enough skill and can hand down the implicit knowledge to posterity. Therefore the art needs the system which glows up successors easily and quickly. In this study, as a first step for developing such skill training system, we searched the inner state of artisans by measuring respiration, and myoelectric potential. We found the relationship between the rhythm of respiration and that of artisans' movement. We also found from electromyogram that non expert tends to overplus power of brachioradialis muscle.
