Emotional expression through animal-like ear movements has become common in animation and video games. However, in dialogue-heavy cinematics, the growing production workload makes it difficult to consistently apply detailed emotional animation.This study analyzes the relationship between ear movements and emotional states across multiple works and proposes an LLM-based method to estimate character emotions from dialogue and plot information. The analyzed results are integrated into a game engine to procedurally generate ear animations. The proposed approach aims to enhance production efficiency while maintaining consistent emotional expression. |
