Tokyo Games to showcase cutting-edge technologies

NTT Docomo

By Kisaki Ozawa and Takuya Ono / Yomiuri Shimbun Staff Writers One of the core concepts of the 2020 Tokyo Olympics and Paralympics is the utilization of the most advanced technologies in the world. The events will provide a good opportunity for Japanese companies to impress the world with their cutting-edge technologies through supporting spectators and athletes.

“I couldn’t see the play well. It was too far. Let me review the play with the replay images.”

At a soccer stadium, spectators with augmented reality goggles, which look like glasses equipped with a device, would put their hands above the goggles to instantly display a goal on the glasses. By switching scenes, they would be able to see the manager and substitute players on the bench. Data on players and teams would also be displayed.

Such a goggle-type device for sports venues is being developed by NTT Docomo, Inc., with 2020 in mind. The wearable device would enable spectators to watch images, sent wirelessly from a number of cameras installed at the venue, while watching the games.

A key technology for this is 5G, or the fifth-generation telecommunications system. Compared with current mobile devices, the high-speed, large-capacity 5G communications will process about 100 times more data. Hiroshi Baba, chief of the sports and live business promotion section at NTT Docomo, said, “The high-speed and large-capacity 5G communications with no data transmission delay will create a new sports viewing experience.”

NTT Docomo plans to distribute high-resolution images and data that can be seen on special devices to spectators’ seats and other places at the 2019 Rugby World Cup in Japan starting in September.

“A suspicious middle-aged man carrying a large bag,” and “wearing a green jacket and jeans.”

Based on such reports, a system has been developed by Hitachi Ltd. in which artificial intelligence singles out a suspicious individual from security camera footage. The system will make it possible to immediately spot a suspicious person at public transportation facilities and other places, based on information including gender, clothes and belongings.

When the system is connected to multiple cameras, it becomes possible to track the moves of a suspicious person in chronological order by checking which camera spotted the individual and when. The system can also be useful for finding lost children. Demonstration experiments have been underway at facilities domestically and abroad, including Haneda Airport, aiming to put it into practical use by the end of fiscal 2019, which ends in March.
