Outline of Final Research Achievements

We developed new theories to understand many facets of games, both from objective and psychological points of view. We proposed two indicators for search-tree algorithms: the probability-based proof number (PPN) and the single conspiracy number (SCN), and applied them to various games. The results revealed interesting information on what each indicator brings to the table. The PPN-based search provided a means for determining the quality of information to operate in a similar fashion to human intuition. Contrarily, the SCN-based search provided a platform to understand the player's experience. Additionally, the SCN-based search approach was linked with the motion in mind, which analyzes various objective and subjective aspects of the game-playing experience by drawing analogies with motion-related concepts from physics. By comparing the SCN with these analogies of motion in games, we found that the underlying computations are directly related to the oscillations that happen in games.

Academic Significance and Societal Importance of the Research Achievements

日本ではマンガ，アニメ，ビデオゲームに代表されるエンタテインメント産業を活発に展開し，我が国の象徴的なものとなっている．一方，エンタテインメントの原理に関する学術的な側面での研究は停滞し，結果として，エンタテインメント産業界でも欧米等の後塵を拝する傾向にある．本研究では，エンタテインメント科学の先駆的役割を果たしたゲーム洗練度理論をベースとして，思考の世界の力学という新たな理論を提唱し，遊戯性の指標を導出した．こうして，これまでにないエンタテインメントの評価法が確立し，さらには，エンタテインメントシステムのより精密なデザインを可能とした．産業面でも様々な分野で快適さを取り込むことが期待される．
