Breakingの概要
Breakingとは?
● ブレイクダンス
● NYのSouth Bronxにて1970年代初頭に
生まれる
● HIPHOP4大要素の1つ
○ DJ, MC, Graffiti, Breaking
● バトル形式がメイン
● 2024年パリオリンピック種目にも採用
● おもにトップロック・フットワーク・
パワームーブ・フリーズで構成される
出典: 【コラム】ブロック・パーティを振り返る、もしくはBボーイ・スタンス2018

BreakingにおけるOriginalityの重要性
Breaking文化の根底を構成・発展させてきた重要な概念
● 自身の価値観を組み込んだ独創性溢れる動きの創造
● 互いのオリジナリティを活発に披露し合う中で発展
● 新しい動きを創造していく面白さ・楽しさ
ORIGINALITY
競技化・勝敗重視による不十分な反映への危惧
DanceAI Project が目指すもの
創作現場におけるAI活用
事例の一部
● イラストの画風転写や自動着色
● 小説のタイトルや内容の自動生成
● 楽曲制作におけるメロディーやドラ
ムパターンの生成
“Originality of Breakdance” で画像生成した例
※Hugging Face Spaces: Stable Diffusion 2.1 Demo より
学習データの扱いで問題になることも!
創作現場におけるAI活用
ダンス分野での事例
● 動画を入力としたダンスの熟練度評価
● 任意の人物の静止画をプロダンサーの動きにトレース
● 短いモーションを入力としその続きを新たに生成
現状ではオリジナリティの支援が不十分?
本プロジェクトにおけるOriginality
Breaking におけるオリジナリティとは?
ダンサーの固有性や由来が見える何か
独特な身体の使い方、身体の特徴、動きの組み合わせ方、Breakingへの価値観
それらの身体・思考・姿勢も含めた側面の一貫性や規則性
オリジナリティの成熟過程
身体・思考・姿勢も含めた自分の一貫性を自覚し、それらを成熟させていく過程
Originality 創発モデル
これら成熟過程の支援が本プロジェクトのねらい

Originality の成熟
ここにアプローチ
THE FRESHEST AI
❏ 両足首に固定したデバイスから加速度データを取得
❏ MbientLab の MetaMotionR を使用
❏ オリジナリティの程度でラベル付け(Level1~4)
❏ 記録したデータをCSV形式で記録するアプリを開発
❏ Keras で機械学習モデル(CNN)を構築して学習
❏ CoreML で学習済みモデルを変換し上記アプリに組み込み
THE FRESHEST AI
❏ 前述したアプリに加え可視化専用のアプリも開発
❏ 加速度や分類結果のラベル、各確率
❏ 上記の推移グラフ
❏ openFrameworks を使用
❏ かっこよくビジュアライズ!

現在の考えと今後
オリジナルな表現を支援する AI を作るために……
「オリジナリティとは何か?」
を考え深めていくことが必要
