沉浸式虚拟环境（IVE）中用户的完整视觉表现可以增强用户在虚拟世界中的主观感受。通常，这需要用户穿上全身动作捕捉服来跟踪真实世界的身体运动，并将它们映射到虚拟身体模型上。在本文中，我们提出了一种增强虚拟方法，允许在虚拟环境中使用附加在头戴式显示器上的相机合并自己的现实视图。所描述的系统可以很容易地集成到典型的虚拟现实设置。由视频透明系统捕获的以自我为中心的相机图像被实时分割成前景，显示用户身体的部分，例如她的手或脚，以及背景。分割的前景然后作为插入显示在用户当前的虚拟世界视图中。因此，用户能够在任意的虚拟世界中看到自己的身体，包括皮肤色素沉着和毛发等个人特征。
A fully-articulated visual representation of a user in an immersive virtual environment (IVE) can enhance the user's subjective sense of feeling present in the virtual world. Usually this requires the user to wear a full-body motion capture suit to track real-world body movements and to map them to a virtual body model. In this paper we present an augmented virtuality approach that allows to incorporate a realistic view of oneself in virtual environments using cameras attached to head mounted displays. The described system can easily be integrated into typical virtual reality setups. Egocentric camera images captured by a video-see-through system are segmented in real-time into foreground, showing parts of the user's body, e. g., her hands or feet, and background. The segmented foreground is then displayed as inset in the user's current view of the virtual world. Thus the user is able to see her physical body in an arbitrary virtual world, including individual characteristics such as skin pigmentation and hairiness.
