The lab researches digital twins, from communications to applications.

AboutAbout the lab
A world seamlessly connected everywhere.
The Shimonishi Lab researches technologies for building and using digital twins, which are digital copies of the real world, in real time.
In communications, the lab covers estimating radio conditions for Beyond 5G/6G, the next-generation communication technology, and optimizing distributed AI edge-cloud systems.
In recognition and data, the lab covers identifying many objects and positioning them in 3D, as well as technologies for collecting and generating real-world data with low latency.
In applications, the lab researches building and sharing metaverse spaces that enable communication across time and space.
Key terms
- Digital twin
- A digital copy of the real world. It is another real world built in cyberspace and can be used, for example, to predict problems that may occur in the real world
- Beyond 5G/6G
- A new generation of communication technology that follows 5G. It is being researched as a foundation for building large-scale digital twins in real time everywhere
- IP multicast
- A communication method that sends the same data to multiple recipients at once. It eliminates wasted transmission and allows data to be collected effectively

ResearchResearch themes
The Shimonishi Lab researches technologies for building and using digital twins, which are digital copies of the real world, in real time. Its research themes range from communication infrastructure, object recognition, and data generation to applications such as building and sharing metaverse spaces.
*Illustrative imageCommunication Infrastructure Supporting Digital Twins
As a foundation for building large-scale digital twins in real time, the lab researches system optimization for Beyond 5G/6G communications. It covers techniques for estimating wireless radio conditions and for optimizing distributed AI edge-cloud systems.
*Illustrative imageProbabilistic Digital Twin Construction
To recognize objects in 3D space quickly and accurately, the lab researches techniques that use machine learning and graphical models to identify many objects and determine their 3D positions. It also covers techniques for reflecting the results in human behavior.
*Illustrative imageData Generation for Digital Twins
The lab researches technologies for collecting and generating the enormous amount of data produced in the real world with low latency. Its work includes research on generating digital twins while collecting data through stream processing, and research on collecting and generating data without waste using IP multicast.
*Illustrative imageApplications of Digital Twins
Digital twins make it possible to communicate across time and space and to predict problems that may occur in the real world in the future. The lab researches and develops the building and sharing of metaverse spaces so that these can be done comfortably.
