Previous section: Applications of Hypervideo
Hypervideo recent entrance to the hypermedia
has prompted great interest and expectations. However is still
necessary to continue researching and exploring the affordances
of hypervideo. This section presents seven areas that the
hypervideo field needs to address in future research.
- Continue researching aesthetic and
rhetoric properties of hypervideo. While some
aesthetic and rhetoric considerations of hypervideo such
as linking video to text have been researched, it is
necessary to research other aesthetic and rhetoric
considerations of interaction with other media or
combination of media types.
- Continue the development of standards.
Even though there is a great effort to develop a standard
for the presentation of multimedia, there is still much
work to do. The standard must meet the requirements of
open, distributed, easy to use, and extensible systems.
Also the standard must contemplate the possibility of
dynamic specifications such as dynamic segmentation and
dynamic synchronization of hypervideos. The static
specification of a dynamic media such as video would not
- Integration of hypervideo to Internet.
Due to the importance of Internet, both as a
communication medium and the economic interests behind
it, hypervideo systems need to target Internet in order
to gain user acceptance. For similar reasons, hypervideo
systems should be integrated with the Web or at least to
- Automatic generation of hypervideos.
As hypervideo systems are more accessible, it is
going to be desirable to link and address documents
archived in digital libraries and multimedia databases.
This research thread may help to integrate integration of
such multimedia documents.
- Dynamic segmentation. The issue of
dynamic segmentation of hypervideos is still unresolved.
The use of frames as nodes seems to violate, at least
conceptually, the rhetoric of hypervideo, since there is
no idea of sequential presentation for a single frame.
Also frames impose a heavy load, even with the aid of
state-of-the-art tools. The concept of scenes, while
seems to be appropriate, imposes a fixed interpretation
of the content of the video. The use of a video as a
single node may prove difficult to handle due to the size
of videos. A dynamic segmentation of videos would get the
best of all these approaches.
- Dynamic synchronization. Just as
dynamic segmentation is required to comply with the
different needs of different user and different
situations, dynamic synchronization is also required in
order to support episodes.
- Hypervideo Authoring Systems.
Current state-of-the-art hypervideo authoring systems
still cannot provide support for a complete hypervideo.
Research is still needed in order to determine how to
provide the best support for hypervideo.
