Video-based E-learning, Analysis and Documentation


The Mobile Interactive Video Component

Video content has become a popular media type within mobile environments. Video recordings can help to report and archive the status of building progresses or to indicate problems e.g. on the construction site. With the concept of video annotation a user can combine details in a video with further information. Thereby, an effective access mechanism is established in order to retrieve information from annotated video sequences. The specific information that is linked to a detail in a video can be of different media types, like a text, an image or an audio sequence. These so-called hypervideo documents can be generated and presented on mobile end-devices.

Video-Documentation

One of the main advantages concerning the medium video is its realistic presentation of the reality. In such a way hypervideo can be used for documenting real situations. In a following post-process such hypervideo documentations are enhanced by the integration of video annotation. Thereby, details in video sequences can be linked with other multimedia content providing more detailed information about each object in question.




Video-Analysis

Hypervideo is an excellent opportunity to collaboratively perform video-analysis. A community can express their observations in different symbol systems (such as picture, texts and narrations) and combine these with the objects in the video sequences. In such a way a dynamic and powerful access mechanism is established that supports the video based communication between participants in distributed scenarios.




E-Learning

In the area of e-learning hypervideo can be introduced in order to foster the transfer of knowledge in terms of complex processes. Thereby, hypervideo allows the authentic visualization of dynamic processes and the combination of video objects with other symbol systems (such as picture, texts and narrations) by the integration of hypervideo-links. Learners can extend the interactive hypervideo-presentation by own video annotations and so share their knowledge and ideas with others in e-learning communities.
