当研究身体大小的自我感知时，创建可以变形以模拟身体大小的真实变化的个性化化身是有用的。一个缺点是，与依赖于一般化绘图的评级量表相比，这些方法是资源密集型的。关于身体感知评级如何在不同的方法之间进行比较，特别是在可视化中不同层次的个性化细节之间进行比较，我们知之甚少。这方面的知识是必不可少的，告知未来的决策之间的适当权衡个性化的现实主义和资源的可用性。本研究旨在确定不同程度的个性化现实主义对身体大小的自我感知的影响。我们在年轻的成年女性中探索了这个话题，使用了广义的线条画比例，以及几种类型的个性化化身，包括沉浸式虚拟现实（VR）中呈现的3D纹理图像。使用广义线条画的身体感知评级往往高于使用个性化的可视化方法的反应。虽然个性化的细节似乎有助于识别，但包含不同数量的个性化现实主义的三个条件之间几乎没有差异（例如，照片般逼真的纹理）。这些结果表明，使用基于个性化纹理和肢体尺寸的尺度是有益的，尽管沉浸式VR中的呈现可能不是必需的。
The creation of personalized avatars that may be morphed to simulate realistic changes in body size is useful when studying self-perception of body size. One drawback is that these methods are resource intensive compared to rating scales that rely upon generalized drawings. Little is known about how body perception ratings compare across different methods, particularly across differing levels of personalized detail in visualizations. This knowledge is essential to inform future decisions about the appropriate tradeoff between personalized realism and resource availability. The current study aimed to determine the impact of varying degrees of personalized realism on self-perception of body size. We explored this topic in young adult women, using a generalized line drawing scale, as well as several types of personalized avatars, including 3D textured images presented in immersive virtual reality (VR). Body perception ratings using generalized line drawings were often higher than responses using individualized visualization methods. While the personalized details seemed to help with identification, there were few differences among the three conditions containing different amounts of individualized realism (e.g., photo-realistic texture). These results suggest that using scales based on personalized texture and limb dimensions are beneficial, although presentation in immersive VR may not be essential.
