Process of delivering multimedia learning objects such as text, video, images, audio, and animation requires real-time streaming of multimedia content from the M-learning systems to the mobile users. With enhancing the integration methods of the mobile devices into the learning systems, we have possibility to allow easy storing, recording and delivering of multimedia contents to the students in...

Das Datenvolumen, das Suchmaschinen indexieren, ist in den letzten Jahren rasant angestiegen und zusätzlich zu der klassischen Domäne Text, bekommen Multimedia-Dateien zunehmend eine wichtige Bedeutung. Dazu zählen in erster Linie Bilder, aber auch Sprache und Filme. Zusätzlich zum kontinuierlichen Anstieg des Volumens bedeutet die Erschließung dieser neuen Domänen aber auch, dass neue Verfahre...

We describe various multimedia applications that demand a fast approximate text search. Each application requires a specific method of implementing the approximate text search. We present important algorithms and implementation methods and their characteristics concerning throughput rate and flexibility. A text processor with a very high text throughput rate has been fabricated for hardwareacce...

In this paper, we are interested in XML multimedia document retrieval, whose aim is to find relevant multimedia components (i.e. XML fragments containing another media than text) that focus on the user needs. The work described here is carried out with images, but can be extended to any other media. We propose an XML multimedia fragment retrieval approach based on two steps. In a first step, we...

Because of e-learning environments characteristics of learners include isolation from the instructor or peer learners, therefore providing social cues or emotional feedback has been seriously considered by inserting pedagogical agents into digital contents. However, there exists controversies for introducing pedagogical agents into digital contents, pros are fostering learner motivation and lea...

ÐA robust system is proposed to automatically detect and extract text in images from different sources, including video, newspapers, advertisements, stock certificates, photographs, and checks. Text is first detected using multiscale texture segmentation and spatial cohesion constraints, then cleaned up and extracted using a histogram-based binarization algorithm. An automatic performance evalu...

Electronic publishing, and in particular Web-based publishing, has assumed an increasing importance in higher education. The possibility of delivering learning material to students over an extranet, thus bypassing the need for investment in usual university infrastructure, is clearly an attractive option for many institutions. Teaching staff, even those who are not particularly technically comp...

While some argue digital reading media may impair text comprehension, the empirical literature is ambiguous, in particular when it comes to of narrative texts. Therefore, a comprehensive and systematic meta-analysis studies exploring effect screen on comprehension texts was conducted (k = 32, N 2239). Multimedia interactive functions general, type multimedia functions, change over time, device ...

New hardware offered at reasonable prices allows to develop improved user interfaces for computer systems: I/O devices can capture and present not only text and graphics, but also photos, sound, and video; storage devices (mainly optical disks) provide the capacity needed for those types of data. The effect is not only better user interfaces, but also more information held in the system. Applic...

One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...
