www.ihmc.us Abstract. Knowledge Models are used extensively by the concept mapping community for a variety of purposes, including education, organizing content, and depicting expert knowledge. The CmapTools software suite automatically generates Webbased (HTML) versions of Knowledge Models when they are stored in a CmapServer. As a result, Web browsers are often the tools used to browse Knowledge Models. However, the HTML generated by CmapTools does not take advantage of new technologies, such as large high-resolution screens and tablets like the iPad. In this paper we present new Knowledge Model Viewer programs for the iPad and the Web that provide an improved navigation experience.
