摘要本虚拟实验教学平台是一种运用计算机虚拟现实技术模拟真实实验过程的多媒体计算机辅助教学软件。Authorware是一个图标导向式的多媒体制作工具，使非专业人员快速开发多媒体软件成为现实。它无需传统的计算机语言编程，只通过对图标的调用来编辑一些控制程序走向的活动流程图，就可达到多媒体软件制作的目的。本课题主要是用Authorware设计形位误差测量虚拟实验教学平台。先用三维动画软件模拟出形位误差测量实验的实验过程和注意事项，以此作为外部媒体文件，再在Authorware中设计程序流程并调用外部媒体文件完成平台的设计，最后输出为可执行的计算机辅助教学软件。本课题在用Authorware设计的同时，对用Authorware设计多媒体程序和用传统的编程语言设计多媒体程序做比较，并讨论各自的优缺点。49558

Abstract The virtual experiment teaching platform is a kind of multimedia Computer Assisted Instruction(CAI) software which simulate the process of the real experiment by using the computer virtual reality technology. Authorware(AW) is a multimedia authoring tool icon-based directed which makes the one who is not professional developing multimedia softwares in short cycle come true. It is easy to achieve the goal that developing a multimedia software by calling icons to edit the programming flow chart which control the trend of program without using the traditional computer languages. The project is mainly to design the virtual experiment teaching platform for the shape and position error measuring with AW. First, we simulate the process and note matters which are defined as external files by using the three dimensional animation softwares. Then, we devise the program and invoke the external files to finish the design. Eventually, we export the program as a executable CAI software. In the project, we also compare the AW designing with the traditional computer languages designing and discuss the advantages and disadvantages both.

Keywords: CAI； multimedia instruction software; Authorware; the shape and position error measuring
