Vizclass: Making Computer Graphics Video Lecture from a Script

We have developed an application that enables a teacher to easily create video lectures by simply writing a script. A CG character speaks with voice synthesis while showing slides explaining them with subtitles. The teacher just needs to write the speech lines and simple commands in a text editor, and the CG animation is automatically generated by the application. This time, both the CG lectures and the actual lectures were provided to students in an actual university course, and a survey was conducted to evaluate our method after the course. The result shows that the CG lecture was working well, but there were a few students who were not satisfied with it.
