While most digital communication platforms rely on text, relatively little research has examined how users engage through handwriting and drawing in anonymous, collaborative environments. We introduce Graphonymous Interaction, a form of communication where users interact anonymously via handwriting and drawing. Our study analyzed over 600 canvas pages from the Graphonymous Online Space (GOS) CollaNote and conducted interviews with 20 users. Additionally, we examined 70 minutes of real-time GOS sessions using Conversation Analysis and Multimodal Discourse Analysis. Findings reveal that Graphonymous Interaction fosters artistic expression, intellectual engagement, sharing and supporting, and social connection. Notably, anonymity coexisted with moments of recognition through graphological identification. Distinct conversational strategies also emerged, which allow smoother exchanges and fewer conversational repairs compared to text-based communication. This study contributes to understanding Graphonymous Interaction and Online Spaces, offering insights into designing platforms that support creative and socially engaging forms of communication beyond text.

翻译：尽管大多数数字通信平台依赖文本，但相对较少的研究探讨了用户如何在匿名协作环境中通过手写和绘图进行互动。我们提出“图名交互”这一概念，即用户通过手写和绘图进行匿名交流的通信形式。本研究分析了来自图名在线空间CollaNote的600余幅画布页面，并对20名用户进行了访谈。此外，我们运用会话分析与多模态话语分析方法，考察了70分钟的实时图名在线空间会话。研究发现，图名交互能够促进艺术表达、智力参与、分享与支持以及社会连接。值得注意的是，匿名性并未完全排除通过笔迹识别实现相互认知的可能性。与基于文本的交流相比，图名交互还形成了独特的会话策略，这些策略使得交流更为流畅且会话修复更少。本研究深化了对图名交互及在线空间的理解，为设计支持超越文本的创造性社会交往平台提供了重要启示。
