Another HTML5 Implementation of Web-Com for Embedding Chalk Annotations and Talk Voices into HTML Documents

Abstract

Web-Com is a tool for teachers to record their chalk annotations and talk voices onto a web document to produce a lively e-learning content. It was originally developed as a Windows application in 2005 and then implemented solely on the basis of HTML5 and JavaScript in 2017 so that it may work on any contemporary web browsers. The only drawback of the previous implementation in 2017 was that the original web document had to be transformed into a single static image file to appear in the resulting e-learning content and thus that the dynamical capability of the original web document is lost. This paper presents a much better implementation that produces the resulting e-learning content as another web document where the original web document, the chalk annotations, and the talk voices are embedded as they are so that the dynamical contents like hyperlinks, buttons, animations and movies in the original web document are preserved in the resulting e-learning content.
