用AI让有肢体差异的人也能拥有精准3D虚拟形象。
Toward Inclusive Avatar Design with Limb Differences Through Artificial Intelligence
- 用AI技术构建包容性3D avatar，支持肢体差异者自定义形象。
- 现有系统缺乏多样数据集，且非标准身体动画能力不足。
- 适合关注无障碍数字身份、虚拟社交平等的开发者与设计师。
随着扩展现实技术在社交互动与娱乐中日益普及，3D虚拟形象需体现身体类型的全面多样性。当前多数3D虚拟形象系统仅支持典型身体形态，无法准确呈现肢体差异、截肢或其他形态变异者。本文综述了面向该群体的包容性3D虚拟形象定制的新兴技术方法，以及促进尊重与准确表达的现行准则。我们指出持续存在的挑战，包括多样化数据集的匮乏，以及针对非典型解剖结构的动画表现局限。本文认为人工智能是突破这些限制、推动包容性3D虚拟形象生成的关键路径。
原文摘要 · Abstract (English)
As extended reality becomes more popular for social interaction and entertainment, 3D avatars must represent the full diversity of body types. Most 3D avatar systems only support normative bodies and do not accurately depict people with limb differences, amputations, or other morphological variations. This paper reviews emerging technical approaches for inclusive 3D avatar customization for this group and current guidelines that promote respectful and accurate representation. We highlight persistent challenges, including the scarcity of diverse datasets and the limitations in animation for non-normative anatomies. This paper positions artificial intelligence as a promising path to overcoming these limitations and advancing inclusive 3D avatar generation.
