Context Perception in Video-Based Hypermedia Spaces

摘要

Multimedia hypertext has grown from the basic addition of dynamic media only at "leaf nodes of the hypertext, to higher structured attempts to compose and integrate the different media. One of the core problems in this evolution has been, and still is, the construction and perception of context, making explicit which part of a presentation is relevant when media elements are integrated. The search for contextualized integration of video material with other sources of information has emerged from the work in several domains and from mutually reinforcing needs. The work presented here is centered on this problem: how to provide the perception of context to users or readers, when navigating through a space of heterogeneous media elements, where video plays an important role.
