Inkjet technology, with which we can digitally print, have enlarged its application in many kinds of fields including industrial uses. Recently, technique for printing with digitally embossed structure, which are called 2.5D printing technique, are also realized using inkjet technology. However, it's difficult for usual 2.5D printing technique to form a large embossed structure (in excess of 100μm) at a enough productivity for industrial uses. In order to overcome that difficulty, we developed a new single-pass inkjet system with foamnig agent and inhibiting ink (special ink for inhibiting foam.) Our experimental results show the system can produce an embossed structure in excess of 100 μm at a same productivity to produce that of about 10 μm, and its productivity reaches over 100mm·s^-1. Those specifications indicate that, using our system, 2.5D printing technique can be utilized in industrial uses.

This paper describes a technique for projecting images onto the surface of a real object to give it a new appearance. In particular, this paper introduces dynamic projection mapping, which realizes such a projection in a dynamically changing environment. First, we present the unique technologies required for dynamic projection mapping, including high-speed projectors, high-speed variable focusing, and multiple-projectors control. In addition, we describe how the fusion of projection and real entities opens up a new visual world in perception, with specific examples of mapping to humans, material-appearance manipulation, color manipulation, etc.

Food is a multi-sensory experience, and even a visual presentation of food can affect the food experience, including the perception of the taste and deliciousness of the meal, and the value judgement of food. Taking such effects into consideration, we can realize technologies that enhances our food experience in daily life by utilizing the advantages of projection mapping, which can make the appearance of food and the eating environment appear to change without requiring the user to wear any equipment. In this paper, through the introduction of actual examples of food experience enhancement technologies using projection mapping, I show that food projection mapping can influence not only the enjoyment of eating, but also the perception of taste and deliciousness of food, the satisfaction derived from food, the value judgment of food, and even purchasing behavior, and discuss its possibility and future of food and information technology.

Projection technologies can present visual information with no special preparation on a displaying surface. This feature enables huge display, aerial display, and display on non-planar/moving objects. Projection type volumetric display is one of promising application of the projection technologies. In this paper, we show the advantages of volumetric display that is effective for many factors of three dimensional recognitions. This paper introduces our results of developments on volumetric 3D displays which make cross-sectional images on a rotating screen by using projector. We developed various volumetric 3D display systems which have scroll-shaped or helical-shaped rotating screens. We also developed aerial 3D display using a pair of parabolic mirrors and helical-shaped rotating screen.

The purpose of this research is to create a media system that connects the city, people, and culture in Kanazawa. We developed the projection mapping system for Tsudumi Gate at Kanazawa Station and the spatial media system consisted of large-scale screen and tourist's mobile devices, which was aimed at improving the circulation of the city. In developing a spatial media system to be used in a public city, we conducted a grand design with an emphasis on creating expressions and experiences suitable for Kanazawa city. In addition, to develop production technology suitable for the implementation environment, we constructed and developed the video projection environment and the image production method. Finally, we conducted a demonstration experiment in the city.

This paper introduces our challenge to support activities in line with the educational curriculum of children in a special-needs school by applying mixed reality technology onto real space by using a large-scale floor projection mapping. We have implemented the proposed system, namely FUTUREGYM, to the gymnasium of Otsuka Special Needs School affiliated to the University of Tsukuba. It is an interdisciplinary study that combines the fields of information engineering, developmental psychology, medicine, and special needs education. In this paper, we first introduce the theoretical background of applying projection mapping for whole-body and social interactions to the support of children with neurodevelopmental disorders and their teachers, and how to design projection activities. We then describe the system overview, methods to realize robust tracking, and experiments to supporting skill training and many other applications in the field of special-needs education.

In October, 2021, the newest planetarium theater “MANTEN Nagoya” by the first LED (light emitting diode) dome display in Japan, which is produced directly by Konica Minolta Planetarium Co. Ltd., is opened near the new shopping center “AEONMALL Nagoya Nortitake Garden”. “MANTEN Nagoya” is the 4^ththeater following Ikebukuro, Oshiage and Yurakucho in Tokyo.

In this paper, explaning the history of planetarium, which was born in 1923 and celebrates near 100 years. Then, introducing the development of digitalization accompanying the progress of video technology, and the trends in the immersive dome experience that is more entertaining, as well as traditional planetarium through our products and the directly produced planetarium theaters.

Currently, the technological background that supports museums is undergoing a major change. For example, three-dimensional modeling technologies such as 3D printers, visualization technologies such as projection mapping, and VR (virtual reality) and augmented reality (AR). The latest visualization technologies are having a great impact on museum exhibits and on the research content of geology itself. In this paper, we report examples of the use of these technological systems in the field of geoscience and their application to museum exhibits. In addition, I will introduce the remote education using VR under the emergency declaration that started in 2020, when museums and schools had to close.
