    The purpose of this study is to propose a method of motion visualization to vary the thickness and color of the trajectory of the specific body site by reflecting the velocity, acceleration, muscle activity, etc. It is difficult to intuitively estimate the velocity, acceleration and muscle activity based on the appearance of whole-body motion. The information is necessary for controlling body movements, and are useful for detailed analysis of movements and learning of movements. There are previous studies that superimposing muscle activity, joint angles, and trajectories of specific body-site on motions of whole body, but there is no example that is the same as our proposal that represents the speed and acceleration of movement, or the degree of muscle activity by the thickness and color of the trajectory line. In this paper, the possibility of extracting features of the operation method of the skilled painters based on visualization and the utilization of the beginner to educational contents are described.

    The purpose of this study is to create new ways of enjoying and added value in traditional Japanese rooms (Washitsu) using digital technologies. This paper proposes a new Washitsu performance method by projection mapping, while utilizing the features of Tategu and Washitsu. Concretely, "Digital Shoji", "Tokonoma Installation" was carried out as techniques to create new attractiveness while maintaining the goodness of conventional Washitsu space. This paper investigates new utilization of shoji and possibility of Washitsu space performance. As a result of the verification experiment by this method, it was shown that the proposed method creates new attractiveness of fittings and is effective for the performance improvement of Washitsu space.

    This paper presents a digital interaction that augments throwing money in the tent play and report the tent play using this interaction. Throwing money is known as a rewarding way for the performance from the audience. In order to implement the interaction in an outdoor tent easily, it requires simple equipment to calibrate the markerless tracking system. It took similar days with the past similar tent plays to prepare the performance with the interaction. Further, comparing to the past tent plays, the income of throwing money remarkably increased. Whereas, this paper describes the position of this throwing money interaction in Japanese drama history, and so on.

    The color of the screen in video content is an important element in determining the impression of the content. Since there are cases where a process to be examined is provided from the initial stage of production, the overall color scheme is necessary information when producing video content. However, in order to create the materials for making the color scheme of the entire video from the initial stage of production, it is necessary to have a high level of expertise. It is difficult to introduce them into the current production process. In this research, we have developed a color scheme timeline generation method that simulates and visualizes the color scheme of the entire image using scenarios and art materials that are always created in the early stages of movie production. The initial stage of production was further divided into three stages, and a color scheme timeline was generated using information at each of the rough plotting stage of the scenario, the first draft stage, and the background art material creation stage. The color scheme timeline is generated using information from each stage of the art data creation process. Then visualize the color scheme timeline based on the completed video content and compare it to the color scheme timeline generated from the scenario and art material. The results showed that the accuracy of the color scheme varied depending on the amount of information used, but there was no major discrepancy between the color scheme visualized from the completed video content and the timeline generated from the early stages of production. It was confirmed that the entire color scheme can be simulated. The new process using the color scheme timeline proposed in this research enables us to simulate the color scheme from the initial stage of production.

    This paper proposes a new inpainting method which is aimed at virtual restoration for paint crack. Target images of this research include missing regions which are models for high-density and widespread crack and paint flaking which is beyond a certain size. In conventional research, there is an effective method to restore these missing region. However, it's accuracy of texture extraction and texture selection are not enough. Proposed method improved the problem of conventional method that is including edge in texture by using difference of bilateral filter for texture extraction. Additionally, the accuracy of texture selection improved with use of inpainting method based on space distance. Effectiveness of proposed method can be confirmable by evaluating restored images by RMSE in both color and texture.
