The objective of this research is to enable more effective design and use of virtual worlds. The pervasiveness of visually-oriented online and interactive digital media allows people to represent themselves increasingly through surrogates in virtual worlds. These digital personae are called "avatars," and when they closely represent the user, "self-avatars." Self-avatars enable forms of learning, interaction, and skill development that can increase a user's effectiveness in a virtual world. This project will explore how self-avatars play a significant role through three key components of perception and action: the relationship between action and the perception of space and objects, active acquisition of spatial memory, and the planning and execution of actions themselves. This research will consider three properties of self-avatars themselves, each likely to have an effect across a broad range of situations: (1) the virtual perspective from which the avatar is seen, (2) the nature of the coupling between user size and motion and avatar size and motion, and (3) the naturalness of the interface system by which the user controls the avatar. The work builds on a growing body of knowledge about the role of body ownership in perceptual and cognitive tasks. This framework provides a theory in which to ground the research, a body of empirical knowledge about perception and action in the real world, and established methodologies that can be used for assessing the results of the research. The ability to utilize work from cognitive and perceptual science to solve a problem in computer graphics and user interaction is a major strength of the research. Virtual environments are important in many domains, including architecture, education, medicine, simulation, training, and visualization. The core impact of this research is to enable self-avatars to enhance user experience in virtual environments, which are a major category of computer simulations. A broad impact of this project is that enhancing the user experience will lead to more capable applications of virtual environments in the aforementioned domains. This research will also have utility in entertainment systems, the dominant environments for avatars. It advances discovery and understanding while training students in cross-disciplinary research methods in an innovative intellectual environment. The interdisciplinary nature of the research and its consequent applications, together with the close integration of two research groups, will aid in bringing new students to computer science, beyond the students traditionally attracted to that field.

这项研究的目的是使更有效的设计和使用虚拟世界。以视觉为导向的在线和交互式数字媒体的普及使人们越来越多地通过虚拟世界中的代理人来代表自己。这些数字人物被称为“化身”，当他们密切代表用户时，“自我化身”。“自我化身使学习，互动和技能发展的形式，可以提高用户在虚拟世界中的有效性。 该项目将探索自我化身如何通过感知和行动的三个关键组成部分发挥重要作用：行动与空间和物体感知之间的关系、空间记忆的主动获取以及行动本身的规划和执行。这项研究将考虑自我化身本身的三个属性，每个属性都可能在广泛的情况下产生影响：（1）看到化身的虚拟视角，（2）用户大小和运动与化身大小和运动之间的耦合性质，以及（3）用户控制化身的界面系统的自然性。这项工作建立在对身体所有权在感知和认知任务中的作用的不断增长的知识基础上。这个框架提供了一个理论，在其中接地的研究，在真实的世界中的感知和行动的经验知识，并建立方法，可用于评估的研究结果。利用认知和感知科学的工作来解决计算机图形和用户交互问题的能力是该研究的主要优势。虚拟环境在许多领域都很重要，包括建筑、教育、医学、仿真、培训和可视化。这项研究的核心影响是使自我化身能够增强虚拟环境中的用户体验，这是计算机模拟的一个主要类别。该项目的广泛影响是，增强用户体验将导致在上述领域的虚拟环境的更有能力的应用程序。 这项研究也将在娱乐系统中发挥作用，这是化身的主要环境。它推进发现和理解，同时在创新的智力环境中培养学生的跨学科研究方法。研究的跨学科性质及其随之而来的应用，再加上两个研究小组的紧密结合，将有助于使新的学生到计算机科学，超越传统上吸引到该领域的学生。
