AI 中文摘要
自我疏离是一种有效的情绪调节策略，但由于其认知需求，在个人危机期间可能失效。虚拟现实（VR）提供了一种通过具身自我表征外化心理距离的新方法。本文提出CyberSelf，一种用于情绪支持的VR系统，整合了视觉上与用户相似的化身、克隆的自我语音以及大语言模型（LLM）驱动的实时对话。该系统使用户能在沉浸式VR中与自我表征进行多轮对话，在保持强烈自我相关性的同时实现具身自我疏离。我们在一项短期研究中评估CyberSelf，对比三种自我表征丰富度水平：文本、文本+语音、文本+语音+外观。结果显示，情感与应对指标均呈现显著的前后改善，具体表现为效价、唤醒度、希望感和复原力提升，焦虑和模拟器晕动症减轻。更丰富的表征增加了对话参与度，完全具身化产生最强的情绪调节生理指标。后续为期四周的长期研究表明，这些益处可持续且具有累积性。此外，用户对重构的化身和克隆语音的辨识度与接受度评分很高。总体而言，这些发现表明，具身的、与用户相似的对话智能体为在VR中外化自我疏离、支持情绪调节提供了可行机制。
英文摘要
Self-distancing is an effective emotion regulation strategy; however, it may fail during personal crises due to its cognitive demands. Virtual Reality (VR) provides a novel approach to externalizing psychological distance by enabling embodied self-representation. In this paper, we present CyberSelf, a VR system for emotional support that integrates a visually self-resembling avatar, a cloned self-voice, and Large Language Model (LLM)-driven real-time dialogue. The system enables users to engage in multi-turn conversations with their self-representations in immersive VR, enabling embodied self-distancing while maintaining a strong sense of self-relevance. We evaluated CyberSelf in a short-term study that compares three levels of self-representation richness (Text, Text+Voice, and Text+Voice+Appearance). The results demonstrated robust pre-post improvements across affective and coping measures, specifically increased valence, arousal, hope, and resilience, as well as reduced anxiety and simulator sickness. Richer representations increased conversational engagement, and full embodiment produced the strongest physiological indicators of emotional regulation. A subsequent four-week long-term study demonstrated that these benefits are both sustainable and cumulative. Additionally, users rated the reconstructed avatar and the cloned voice as highly recognizable and acceptable. Collectively, these findings suggest that embodied, self-resembling conversational agents provide a viable mechanism for externalizing self-distancing and supporting emotional regulation in VR.
