用AI角色扮演助画师构建立体角色设定，不替代创作
ORIBA: Exploring LLM-Driven Role-Play Chatbot as a Creativity Support Tool for Original Character Artists
- 让画师与角色对话生成背景故事，聚焦概念构思
- 14位艺术家参与，普遍提升想象力与角色情感联结
- 适合角色创作、创意辅助工具设计者参考
生成式AI为视觉艺术创作带来新机遇，但也引发伦理争议。本文探索如何在尊重创作者自主权的前提下，利用生成式AI支持原創角色（OC）设计。提出ORIBA——基于大语言模型（LLMs）的AI聊天机器人，使艺术家能与自己创造的角色进行角色扮演，重点聚焦于概念化（如人物背景），而视觉呈现仍由创作者完成。对14位艺术家的实证研究显示，ORIBA显著提升了艺术家的想象投入度，帮助构建多维度角色属性，并增强与角色的情感联结，从而激发创作动力。本研究贡献在于从艺术家视角出发，提供可落地的设计洞察，证明大语言模型可在不侵犯视觉创作主权的前提下，有效支持跨模态创意实践。
原文摘要 · Abstract (English)
Recent advances in Generative AI (GAI) have led to new opportunities for creativity support. However, this technology has raised ethical concerns in the visual artists community. This paper explores how GAI can assist visual artists in developing original characters (OCs) while respecting their creative agency. We present ORIBA, an AI chatbot leveraging large language models (LLMs) to enable artists to role-play with their OCs, focusing on conceptualization (e.g., backstories) while leaving exposition (visual creation) to creators. Through a study with 14 artists, we found ORIBA motivated artists' imaginative engagement, developing multidimensional attributes and stronger bonds with OCs that inspire their creative process. Our contributions include design insights for AI systems that develop from artists' perspectives, demonstrating how LLMs can support cross-modal creativity while preserving creative agency in OC art. This paper highlights the potential of GAI as a neutral, non-visual support that strengthens existing creative practice, without infringing artistic exposition.
