“Digital Museum” began as an alternative to display in an exhibition room, using high-resolution image data. The concept of it has gradually changed to an expansion of museum experience and comprehension by digital technology and many technical trials have been carried out to date. This essay introduces some types of digital museums on the Internet during the COVID-19 pandemic and discusses that digital museums have possibilities to help social inclusion that real museums couldn’t have done.

The exhibition viewing experience is not linked to the use of digital collections. Questionnaire surveys reveal that viewers enjoy exhibitions with an attitude of taking their time to view artworks alone, while at the same time showing a lack of interest in viewing artworks remotely. In this paper, we assume the art exhibition viewer as a user and examine his/her gaze toward digital collections. The example of music streaming services then suggested that it may be effective to present a large number of curation results. By making the flow line to the digital collection more visible, it is expected to make it easier to visualize the experience process itself.

"Kahaku VR" is a Digital twin that records the Permanent Exhibitions of the National Museum of Nature and Science using 3DVR technology., it was developed as a public relations activity so that children could visit virtually during the period when going out was restricted due to the declaration of a state of emergency. After the release, the scope of use has been expanded in various ways, and content has been added and updated. In this paper, I report on these as examples. I think it is important that museum exhibition activities be archived using 3DVR technology.

“Hyper Edohaku”, the official app of the Edo-Tokyo Museum, is an app for mobile devices that allows users to enjoy the museum’s exhibits and collections online. The development of this application is an example of digital archive utilization, but we sought a new approach that is distinct from conventional museum-provided content and presents a new example of utilization. In this report, we provide an overview of the app and the background and process of its creation, and then consider the significance of this app from the perspective of promoting the utilization of digital archives. What became apparent through collaboration with a company specializing in digital technology is the possibility of revitalizing the utilization of digital archives by involving other fields and industries.

NTT DATA Corporation has been implementing various platforms through its digital archiving business. This report focuses on overseas case studies, including those of the ASEAN countries and the Vatican City, in terms of how to "utilize" the contents.

This paper is a report of an experiment using e-textbooks with a bundled license model in university classes. In recent years, there has been a tendency to replace textbooks, such as academic / specialized books, with teaching materials such as partial copies of books and teacher-made slides. In that case, there is a possibility that universities will be disadvantaged due to concerns over copyright law infringement and deteriorating profits for publishers due to a shift away from textbooks. As a countermeasure for this problem, we tried a bundle type license model that allows the use of multiple e-textbooks requested by teachers. As a result of the experiment, two out of the eight classes in total were successfully adopted, confirming the possibility of usage.
