(成果)
和歌山大学システム工学部天野敏之教授を山頂にお越しいただき，最新の AI 技術を融合したプロジェクションマッ
ピングに関するご講演をして頂いた．山頂測候所をお借りしてセミナーを実施する計画は元々2019 年に下見を実施し，2020 年に第１回目を実施する予定であったが，コロナ禍で２年延期となり，昨年 2022 年に実施しようとしたものの悪天候のため山頂までたどり着くことができず，セミナーは中止となり，ようやく今年，初開催にこぎつけることができた．３年越しの初開催となった．参加者は電通大柳井研究室の学生・卒業生を中心に当初 14 人の予定であったが，コロナ感染など体調不良で 3 人が取りやめとなり，11 人でなった．
８月２８日（月）の朝９時に５名が御殿場口から，朝 11 時に 6 名が富士宮口から登山を開始し，途中で合流し御殿場口７合目わらじ館にて宿泊．翌朝，小屋前でご来光を見てから山頂へ向けて出発し，山頂休憩所で休憩した後，測候所へ１１人揃って入館，準備も含めて約２時間のセミナー講演を実施した．その様子は Zoom でも中継され，参加できなかった学生や関連の研究者などが視聴した．セミナー後は，御殿場口から大砂走りを経て，御殿場口五合目に午後４時に無事全員下山を完了した．
講演内容は「プロジェクタカメラ系によるリアリティの操作」に関するもので，光学的な特性や知覚メカニズムに基づく光線投影で物体の見かけの色彩や質感を変化させる最新技術についてご講演いただきました．また，実世界でのインスタレーションへの応用事例，具体的には日本橋三越や二条城でのプロジェクションマッピングイベントに関してもご紹介いただきました．最後に，富士山剣ヶ峰へのプロジェクションマッピングの可能性についても熱く語っていただきました．電力確保の問題はあるものの，技術的には可能であるということでした．
（英文）Mt. Fuji Summit AI Seminar(Results)

We invited Prof. Toshiyuki Amano, Faculty of Systems Engineering, Wakayama University,
to the summit to give a lecture on projection mapping integrated with the latest AI technology.
The plan to hold the seminar at the Mt.Fuji research station was originally planned in 2020, but
was postponed for two years due to the corona disaster, and was to be held in 2022 but could notreach the summit due to bad weather conditions. The seminar was finally held for the first time
this year, three years after we planned originally. The number of participants was originallyplanned to be 14, mainly students and graduates of the Yanai Laboratory of the University ofElectro-Communications, but three people had to cancel due to corona infection or other healthproblems, resulting in 11 participants.
On Monday, August 28, five members started at 9:00 a.m. from the fifth station of theGotemba Route and six from the fifth station of the Fujinomiya Route at 11:00 a.m., joining eachother on the way and staying overnight at Warajikan at the seventh station of the Gotemba

Route. The next morning, after watching the sunrise in front of the hut, we departed for thesummit, took a rest at the summit rest house, and then all 11 of us successfully entered theresearch station for a two-hour seminar, including preparation time. The seminar was broadcast
via Zoom, and the students who could not attend the seminar and some researchers watched iton the ground. After the seminar, all participants safely descended the mountain at 4:00 p.m.
from the top of the Gotemba Route via Osunadori to the fifth station of the Gotemba Route.
The content of the lecture was on "Manipulation of Reality by Projector-Camera System," inwhich the latest technology to change the apparent color and texture of objects by projecting lightrays based on optical characteristics and perceptual mechanisms was presented. He also
introduced examples of real-world installation applications, specifically projection mapping
events at Mitsukoshi Department Store in Nihonbashi and Nijo Castle. Finally, he told
passionately about the possibility of projection mapping on the Kengamine summit of Mt. Fuji.
Although there is a problem of providing electric power, he said it was technically feasible.
