Creating New Value through Collaboration

Functional material hitoe®

hitoe® is a functional material that was developed jointly with Toray Industries. Biometric signals can be measured and collected when a user wears clothing that incorporates hitoe®. These biometric signals, which are weak electrical signals emitted by the body, include electrocardiographic, electromyographic, and electroencephalographic signals. Since 2014, NTT DOCOMO has provided Runtastic for docomo, a service that supports training through the recording and management of data measured with the use of hitoe®.

In addition, with the objectives of realizing heat countermeasures and safety management for work performed alone, such as late at night, we worked together with Toray to develop clothing that offers superior comfort. Moreover, we acquired and analyzed data and implemented initiatives to build a system with high level of accuracy and superior usefulness. We recently began to provide a service that uses hitoe® to monitor workers.

We are currently advancing collaborative initiatives with partners in a variety of industries, and moving forward we will strive to identify further possibilities for business creation.

●Strengths of hitoe®

·When a user wears clothing that incorporates hitoe®, it is possible to monitor biometric information for the heart rate, electrocardiogram waveform, and accelerometer for long periods without stress.

·It is possible to evaluate both physical and mental condition through analysis of the biometric information that has been acquired.

·It is possible to monitor multiple people simultaneously and in real time because the results of the analysis are managed on the cloud.

Crashless Car

Together with Toyota and Preferred Networks, NTT has implemented a demonstration of the concept of Crashless Car. Toyota’s concept of AI driving was realized with the use of NTT’s edge computing technologies and high-reliability wireless technologies and the utilization of Preferred Networks’ deep learning technologies and distributed processing technologies.

Preferred Networks’ AI, which runs on edge servers that are deployed on the periphery of networks, learns about the surrounding environment, which changes from moment to moment. In line with the circumstances, driving support information is provided in real time, and by sharing the learning statuses of multiple vehicles, the time required for learning is reduced. In the future, real-time data collection from multiple vehicles and roadside infrastructure equipment will foster the realization of advanced driving support, such as traffic congestion forecasts and the establishment of traffic priorities for vehicles in times of emergency or disaster.

Initiatives for 2020


Kirari! is an immersive telepresence technology that combines next-generation compression standards (HEVC) and Advanced MMT, a technology that synchronizes various media to produce highly realistic sensations developed by NTT. Kirari! will enable the transmission of not only athletes’ images and sounds but also information about their surroundings and environment. With projection mapping technology, Kirari! makes it appear as if athletes are competing right in front of the viewers, even from remote locations. To date, we have conducted testing with partners in a wide variety of fields, including not only sports but also culture and entertainment. For example, together with DWANGO and Shochiku, we have taken on the challenge of realizing an entirely new Kabuki experience.

Targeting 2020, we continue to advance R&D for Kirari!. Through the creation of highly realistic sensations, we will aim to transmit and reproduce in real time the entire game spaces, not only in Japan and but also around the world.

Through the utilization of Kirari! technology in such areas as sports competition and concerts, it will be possible to enjoy realistic sports viewing and public performances even from remote locations.

Visual Search

Visual Search uses NTT’s Angle-free Object Recognition Technology. We are making progress with testing of Visual Search as one facet of R&D initiatives for the purpose of using ICT to provide world-class experiences, impressions, and hospitality for visitors to Japan in preparation for 2020. When visitors have a question about a transfer at a station, they can simply point their smartphone, tablet, or other device at the information board. The information that they need to proceed to their destination, such as a map showing the current location and route guidance, is translated into an appropriate language and provided to them. The limits on such factors as viewing angle at the time of recognition are less restrictive than those for QR codes and bar codes, and there is no need to move close to take a picture. Accordingly, Visual Search will contribute not only to increasing convenience but also to alleviating congestion. At Haneda Airport International Passenger Terminal and nearby Tokyo Station, we are already moving ahead with testing to improve image recognition accuracy and to verify usefulness in such areas as guidance expressions.
