How can animation be used to promote learner understanding of scientific and mathematical explanations? In this review, we examine the role of animation in multimedia learning (including multimedia instructional messages and microworld games), present a cognitive theory of multimedia learning, and summarize our program of research, which has yielded seven principles for the use of animation in ...

Multimedia presentations typically produce better memory and understanding than do single-medium presentations. Little research, however, has considered the effect of multimedia on memory for nonmultimedia information within a large multimedia presentation (e.g., nondepicted text in a large text with diagrams). To this end, the present two experiments compared memory for target text information...

Students learned toy assembly sequences presented in picture, text, or one of three multimedia formats, and completed order verification, recall, and object assembly tasks. Experiment 1 compared repetitious (i.e. dual format presentations each conveying similar information) with complementary (i.e. dual format presentations each conveying different information) multimedia presentations. Repetit...

The goal of a multimedia text extraction and recognition system is filling the gap between the already existing and mature technology of Optical Character Recognition and the new needs for textual information retrieval created by the spread of digital multimedia. A text extraction system from multimedia usually consists of the following four stages: spatial text detection, temporal text detecti...

Multimedia Database Systems (MMDS) support rich data types, such as text, images, video, and sound. Queries in MMDSs may refer to the content of the stored multimedia objects. This is called content-based querying. However, manual entry of content descriptions is very difficult and subjective. A better approach is to provide automatic content-based retrieval through image, text, and sound inter...

Research on metacognition has consistently demonstrated that learners fail to endorse instructional designs that produce benefits to memory, and often prefer designs that actually impair comprehension. Unlike previous studies in which learners were only exposed to a single multimedia design, the current study used a within-subjects approach to examine whether exposure to both redundant text and...

Objects composing a multimedia presentation need to be delivered based on the temporal relationships specified by the author(s). Hence, even discrete media objects (that do not normally have any real-time characteristics) have temporal constraints on their presentations. Composition of multimedia presentations can vary widely. Based on their composition, we can consider three broad categories o...

With the rapid development of multimedia and network technology, people can access a large number of multimedia information. For people who want to make full use of multimedia information resources, the primary question is how to query the multimedia information of interest. Text query can be applied to multimedia information retrieval, but it has inherent deficiencies. One hand, text annotatio...

Multimedia contents such as images and videos are widely used in social network sites nowadays. Sina Weibo, a Chinese microblogging service, is one of the first microblog platforms to incorporate multimedia content sharing features. This work provides statistical analysis on how multimedia contents are produced, consumed, and propagated in Sina Weibo. Based on 230 million tweets and 1.8 million...
