为了降低生产的三维计算机图形（3DCG）的教育内容的电子学习系统的成本，并提高自主学习系统的能力，我们开发了一个新的自主学习系统的基础上的赛博人，一个人形的软件机器人，通过使用3DCG和语音合成。我们的系统包括一个3DCG舞台，许多舞台部件（例如，3DCG形状的模型，照片，文本面板），和网络人物。因为网络人作为一个虚拟的老师，我们命名为网络助理教授（CAP）。CAP的教育内容可以用Cyber Person Scenario Language 2（CPSL 2）编写。CPSL 2是一种基于标签的超文本语言，类似于HTML，描述了3DCG交互式动画的场景。CAP浏览器将此场景转换为实时交互式3DCG动画，而不是渲染影片。CAP可以通过使用身体动作、面部表情和说话来指导教育对象。载物台部件也可以根据CAP的指令同时移动。有时，CAP向学习者显示一个问题，学习者必须通过点击指定的阶段部分来回答，例如，选择正确的答案或输入正确的数字。作为响应，CAP可以更改3DCG动画的场景或加载适用的外部场景文件。我们曾经为小学生开发过一些教材。
To reduce the cost of producing 3D computer graphics (3DCG) educational contents for e-learning systems and to improve the capability of self-learning systems, we developed a new self-learning system based on a Cyber Person, a human-shaped software robot made by using 3DCG and speech synthesis. Our system includes a 3DCG stage, many stage parts (e.g., 3DCG shaped models, photographs, text panels), and Cyber Person (s). Because the Cyber Person acts as a virtual teacher, we named it Cyber Assistant Professor (CAP). The educational contents of CAP can be written in Cyber Person Scenario Language 2 (CPSL2). CPSL2 is a tag-based hypertext language, like HTML, that describes a scenario of 3DCG interactive animation. A CAP browser converts this scenario to real-time interactive 3DCG animation, which is not a rendering movie. CAP can instruct the educational subject by using body actions, facial expressions, and speaking. The stage parts can also move simultaneously corresponding to the CAP's instructions. Sometimes, CAP shows a question to the learner and the learner has to answer by clicking the specified stage parts, e.g., selecting the correct answer or entering the correct number. In response, CAP can change the scenario of 3DCG animation or load the applicable external scenario file. We have used to develop some teaching materials for elementary school students.
