This system will enable people around the world to ‘telepathically’ communicate with each other without being restricted by physical time and space.Creating the Cyber World Using Information in the Human Brain (Brain Language) and XR Technologiesue to the ongoing COVID-19 pan-demic and other natural disasters, many of people have been forced to severe-ly restrict their social activities. Because this type of catastrophe could reoccur in the fu-ture, it is desirable to fundamentally enhance the capability of our social systems so that we can more adequately cope with adversity while keeping our lives as close to normal as possible. The creation of a cyber world may potentially enable us to continue to engage in various activities (e.g., personal and occu-pational activities and social interaction with others) irrespective of real-world restrictions.■ R&D brain-based communicationsRecently, rapidly advancing ICT, such as AI and 5G, are bringing cyber world concept into reality.—Although the use of these tech-nologies may increase the volume of infor-mation available to us, the human brain can efciently process only a limited amount of information before feeling fatigue. Notably, stimulated brain information is often high in quality, not quantity. Interpreting the infor-mation processed in the brain—or what we call “brain language”—is the critical step in developing a brain-to-brain communications system. Here, we describe the concept of a hy-perreal, cyber world, which may be developed using “brain language” and XR (cross reality) technologies (Figure 1).How can we extract “brain language”? Re-search to interpret information in the human brain or “brain language” by analyzing brain activity is making signicant progress in re-cent years. At(CiNet) we have been making major efforts in this research. This article de-scribes some of our achievements.We mea-sured brain activity of human subjects watch-ing a video and attempted to reproduce the images they perceived by measuring brain ac-tivity. Performing cognitive tasks and tried to interpret their high-level cognitive processes, such as perception of semantics, emotion, and intention. Our results have shown success in interpreting brain activity in these experiments (Figure 2).■ Eorts to interpret “brain language”Our goal is to interpret “brain language” generated when humans perceive visual and other types of information. We then plan to Figure 2 Example of “brain language” interpretation process DHow NICT R&D Can Underpin COVID-19 Aected SocietyNICT NEWS 2020 No.610
