Achieving Interoperability Between PowerPoint and Similar Presentation Tools

With the development of e-learning, many authoring tools have been designed and implemented, besides of course authoring tools like eXe, presentation tools like PowerPoint are widely used and play important role in creating learning content. However, most presentation tools do not support PowerPoint files which are very popular in the education because of its complexity. This will lead to poor share ability of existed PowerPoint files. As a result, PowerPoint file converting should be taken into account for achieving interoperability among presentation tools. This paper describes the initial efforts to support PowerPoint converting of a similar presentation tool named MCAT which has been implemented. The file format of MCAT is based of xml. It makes MCAT support PowerPoint files by converting PowerPoint file to xml file. Further, the converted PowerPoint file can be used in three-screen streaming courseware to reduce needed bandwidth by transforming xml file to html file using playing tool.
