Many collaborative systems use text as the primary modality and only use multimedia via attachments. MuSwikis are a collaboration system where graphics are the primary modality, and text is treated just like any other graphical element. This paper describes the MuSwiki system for the first time, describes a pilot study that was run on MuSwikis, and discusses ideas generated from that study.

Background: The perquisite of an effective nutritional intervention is a proper educational method. The aim of this study was to define the effectiveness of nutritional education using discussion group and multimedia on learning of pregnant women. Method: This randomized educational trial was conducted among 174 pregnant women in northeastern Iran, Gonabad city. Participants were assigned rand...

Despite the huge production of all sorts of multimedia instructions, educational research has yielded surprisingly few general design principles for instructions in which verbal and visual information are combined. Instructional designers seem to base their design choices more on intuitive ideas than on sound research results. There are however some interesting theories that give guidelines for...

Ontology development is mostly directed at the representation of domain knowledge and much less at the representation of textual or image-based symbols for this knowledge, i.e., the multilingual and multimedia lexicon. To allow for automatic multilingual and multimedia knowledge markup, a richer representation of text and image features is needed. At present, such information is mostly missing ...

In this paper, the proposed system consists of two parts – multimedia authoring and recordable virtual collaboration in medical training system. The former supports synchronized multimedia presentation using Synchronous Multimedia Integration Language (SMIL). It allows synchronization of the contents of a PowerPoint presentation file and a video file so that the presentation shows slides and vi...

Many different communities have conducted research on the efficacy of relevance feedback in multimedia information systems. Unlike text IR, performance evaluation of multimedia IR systems tends to conform to the accepted standards of the community within which the work is conducted. This leads to idiosyncratic performance evaluations and hampers the ability to compare different techniques fairl...

The field of distributed multimedia systems has experienced an extraordinary growth during the last decade. Among the many visible aspects of the increasing interest in this area is the creation of huge digital libraries accessible to users worldwide. These large and complex multimedia databases must store all types of multimedia data, e.g., text, images, animations, graphs, drawings, audio, an...

We introduce a common architecture to store semantically enriched multimedia material that can be accessed by intelligent engines able to automatically assemble video clips and build textbased hypermedia. The core of the architecture is the Multimedia Database (MMDB), which stores a repository of multimedia information (i.e. text, images, speech, audio, etc.) and its annotation with respect to ...

The integration of audio, video, graphics and text on the desktop promises to fundamentally challenge the centuries-old model of the printed document as the basis for information exchange. Before this potential can be realized, however, systems must be devised that enable the production and presentation of complex, inter-related media objects. These systems are generically called multimedia aut...
