User Meeting 2022



The 12th MECHANICAL FINDER User Meeting 2022 aims to provide on-site participation and presentations with sufficient infection control taken care of. We are planning to hold the meeting in a hybrid following the previous one, but we would be happy if you could join us on site.
This year, we are considering a session in the morning that will be limited to on-site sessions to allow for more exciting discussions. In the afternoon, as in previous years, we will have a session where you can present your research.
Regarding language, in principle, on-site and online language of this User Meeting will be Japanese. Presentations by overseas will be available to on-site and online participants as English video presentations. Presentations available in English on demand are marked “English“. Presentations marked withare available on Youtube.
