为了改善电脑化教育课程，我们建造了辅助设施，让老师和学生可以互动交流。当学生陷入困境时，他可以向老师的驾驶舱发送帮助请求。当教师发现问题情况时，他可以通过语音通信回答问题，也可以尝试通过远程控制操作解决问题。然而，如果许多问题涌向老师的座舱，他必须按顺序联系每个学生。因此，学生们不得不等待很长时间。为了改善这一问题，我们开发了一个网络助教（CTA）的原型。CTA是安装在学生个人电脑上的基于三维计算机图形的Cyber Person软件。CTA通过语音合成器带着面部表情朗读日语文本，并根据网络文件服务器中保存的场景播放指定的肢体动作。教师可以通过远程控制操作，在合适的场景下启动任何CTA。当老师发现学生的问题或帮助请求，如果学生的困难情况可以通过一个典型的或简单的答案来解决，他可以用一个适当的场景开始CTA。因此，CTA减少了学生的等待时间。
To improve computer-based education courses, we constructed support facilities, which enable interactive communication between teacher and students. When a student falls into a difficult situation, he can send a help request to the teacher's cockpit. When the teacher detects a problem situation, he can answer the question by voice communication or can try to resolve it by remote control operation. However, if many questions rush to the teacher's cockpit, he has to contact each student in order. Therefore, students have to wait for a long time. To improve this problem, we developed a prototype of the Cyber Teaching Assistant (CTA). CTA is a Cyber Person software based on 3D computer graphics installed in the student's PC. CTA reads Japanese text aloud by voice synthesizer with facial expression and plays specified body actions according to the scenario saved in the network file server. The teacher can start any CTA with an appropriate scenario by remote control operation. When the teacher detects the student's question or help request and if the student's difficult situation could be resolved by a typical or easy answer, he can start the CTA with an appropriate scenario. As a result, CTA provides a reduction in student waiting time.
