| Abstract | On the World Wide Web, hypertext has provided a powerful mechanism for integrating multimedia as information based on text augmented with image, sound and video elements. However, a broader basis is necessary to structure and integrate a video-centric medium, where the notion of hyperlinks must be redefined to consider the spatial and temporal aspects of video. New interaction paradigms must be developed to navigate in a hyperlinked network, video-driven content called Hypervideo. This work is devoted to the exploring of the mechanisms that allows us to construct this new kind of video-centered presentation making possible enriched forms of navigation, in special, allowing a real navigation through the video. Integrating the temporal dimension on a presentation has been determinant for this purpose. We will study hypervideo particular features, potential uses, tools for its development and production process. In what concerns to potential uses, we will focus on the communication of mathematical concepts. We present in chapter 2 the problematic of communicating Mathematics and we introduce Mathematical Visualization as a technique that can help students on the understanding of abstract ideas. Graphics and video images have been a medium for presenting these visualization results. However, specially in the case of video images, if they are seen in a passive way, their content is not optimally absorbed by the student as its does not provide him time to reflect. This reflection time is essential when trying to understand abstracts concepts. We present hypervideo as a better way to see video images than with VCR. We will explore it as a powerful tool to teach mathematics using the power that video images already have and enriching this content with additional information provided by text, still images, animation and many other kind of media. We present in chapter 3 a general hypermedia model and then our hypervideo model, as a special case of the first one. We will discuss some of the tools that allow constructing this sort of presentation but we will focus on SMIL (pronounced “smile”), Synchronized Multimedia Integration Language. This language is presented in chapter 4. It became a W3C recommendation on 15th June 1998 and has been developed by the SYMM working Group that includes Netscape, Real Networks, Philips, Digital Equipment and others. We present some of the advantages of SMIL as, for example, support for adaptive and independent content. We will also describe some of the players that already support this language like RealPlayer, Grins and QuickTime. In chapter 5, we present the problematic of producing a very new hypermedia product and try to give some general steps when producing a hypervideo. We present, as our |
