IDW '24


I4D Contest

Demonstration Contest for College of Technology Students

(Information in Japanese)

In the IDW ’24, we are introducing a new “I4D Contest” targeting students from colleges of technology (KOSEN). We welcome any demonstrations related to electronic information display technology mentioned in the IDW Scope without specific restrictions. Outstanding demonstrations will be awarded the I4D Best Demonstration Award.

Colleges of Technology (KOSEN)

Colleges of Technology are higher education institutions for junior high school graduates. There are 58 colleges of technology in Japan, and their excellent education system, known as the “KOSEN education system”, has been highly praised domestically and internationally. KOSEN institutions have also been established overseas, including in Mongolia. KOSEN students actively present their research achievements in academic conferences, and their accomplishments in robot contests and programming contests have attracted media attention.
