虚拟现实可以拓宽学生和计算机教师之间的互动类型。与传统的基于模拟的培训一样，计算机可以观看学生练习任务，回答问题并提供建议。然而，沉浸式虚拟环境也允许计算机教师与学生一起沉浸在虚拟世界中。与以前脱离实体的计算机教师不同，这样的“教学代理”可以与学生“身体”合作，实现新类型的互动。为了说明这种可能性，本文描述了Steve，一个虚拟环境的教学代理，帮助学生学习程序性任务。在概述了Steve的能力之后，本文重点介绍了在虚拟环境中以图形方式表示Steve的好处和挑战。
Virtual reality can broaden the types of interaction between students and computer tutors. As in conventional simulation-based training, the computer can watch students practice tasks, responding to questions and offering advice. However, immersive virtual environments also allow the computer tutor to inhabit the virtual world with the student. Unlike previous, disembodied computer tutors, such a "pedagogical agent" can "physically" collaborate with students, enabling new types of interaction. To illustrate the possibilities, this paper describes Steve, a pedagogical agent for virtual environments that helps students learn procedural tasks. After providing an overview of Steve's capabilities, the paper focuses on the benefits and challenges of graphically representing Steve in the virtual environment.
