This is Michihiro Hayashi, Engineering Design teacher at Kanazawa campus. From Wednesday, December 4 to Friday, December 6, 2024, I took a business trip to Sapporo, Hokkaido to participate in the international conference, IDW’24(The 31st International Display Workshops).

 Starting from this year, an I4D Contest (Demonstration Contest for College of Technology Students) was held as part of the conference. One of our 4th year students, Shogo Izumiya, gave a demonstration and a speech there. The theme of the presentation was “Differences in Gaze Direction of 3D- and 2D- Avatars: from Viewpoint of ‘Mona Lisa Effect.’” In a painting of a person on a flat canvas, the “Mona Lisa effect” occurs, where the depicted person appears to be looking at the viewer, whether viewed from the front or a slightly oblique angle. How does this effect manifest in a virtual reality environment using a Head-Mounted Display (HMD)? Our task was to demonstrate this through a practical demonstration. HMD is a device worn on the head like a helmet, which provides computer graphics with a realistic three-dimensional vision right in front of your eyes.

 Right after Shogo arrived at the venue, he was very busy preparing the HMD device, displays and other equipment, and putting up his posters on the walls. This was an international conference that used English as the official language. In this regard, Justin Han sensei, who also teaches Engineering Design with us, provided the language support for the posters and the presentation. Therefore, presentations were also primarily given in English. Sometimes we used Japanese for the Japanese speakers, but all posters and other notices were written in English.

Once the presentation started, other students and researchers visited his booth, listened to his instructions, and tried the HMD devices. Even though he looked a bit nervous at the beginning, he got used to it and gave a better presentation. Besides, his efforts to explain his ideas effectively in English were remarkable and easy to understand. This event took nearly four hours, but he was deeply concentrated on it, unaware of the passage of time. However, he seemed quite tired afterward and recovered his energy by eating a lot of Hokkaido food for dinner. In addition, the best and most excellent presentations were selected by the judges. Although our presentation missed out on being selected, after the awarding ceremony, the executive committee chairperson said, “It was a very close decision. Please come to IDW’25 as well. We are looking forward to seeing you.” The next IDW’25 will be held in Hiroshima in December 2025. We will be able to see Shogo senpai presenting with the new 4th year students there. I am looking forward to going with the group again and enjoying Hiroshima food such as oysters and Hiroshima-style Okonomiyaki.
