Applications of Hypervideo
Hypervideo has recently started to be included
into hypermedia systems. However there is already a great
interest to accelerate its entrance in the hypermedia world. Once
it was thought that video would enter very late into the Internet
world due to its bandwidth requirements. But now that it has been
proved the feasibility of using video in Internet, more and more
persons are looking to make use of it forcing, as it was
discussed in previous sections, changes in the rhetoric of the
whole hypermedia system.
Hypervideo has a large area of applicability.
Almost any application area that already uses video may benefit
from hypervideo. Nevertheless some of the areas that use video,
already implemented some of hypervideo functionality in one or
- Education. Academic professionals
use video for documenting and studying teaching methods
to inform the learning process or develop new educational
programs. Comparison between different videos may require
linking to specific time indexes in different videos. One
example can be found in TIMSS 1998.
- Research and Development.
Researchers and engineers often videotape experiments or
collect observational data to accelerate and enhance
their discoveries. For instance, usability testing
requires to video persons using a system. The resulting
video is then edited such that a coherent result analysis
can be returned to the developers of the system. This
editing and rearrangement of clips is a manual form of
hypervideo. The development of hypervideo systems would
greatly simplify the task of preparing usability reports.
- Computer-Based Training (CBT).
Computer based training encompasses a very large
community. Large enough to divide into specialized
communities that held annual conferences, such as AICC
(Aviation Industry CBT Committee). There are examples of
video usage in all areas of CBT. Currently, CBT
implements some of hypervideo functionality. For
instance, a CBT system usually presents different video
clips depending on the user performance and evaluation.
This requires a concept of segments or nodes (clips) and
links between clips. Better hypervideo systems would
allow for more flexible presentations and would allow the
system to adapt to the user. A hypervideo system may
provide a user-driven CBT, instead of a more traditional
system-driven CBT. For instance a CBT medical system may
use dynamically segmented video clips in order to guide a
persons through a medical procedure. Since a hypervideo
system may be designed as a user-driven system, the
system may synchronize dynamically the hypervideo to the
users actions. Such a hypervideo system implies the
possibility of using dynamic linking, segmenting and
There are even more areas currently using video
that would benefit from the availability of hypervideo systems.
Some of those areas are discussed briefly in the following
- Entertainment. The entertainment
industry can use hypervideo in order to develop different
games or even different hypermovies. This could result on
a new kind of entertainment where the persons can
participate in the movie. There are great expectations
for such an entertainment media.
- Marketing. Advertising executives
and market researchers videotape focus groups to solicit
feedback and devise effective marketing strategies. Also,
in the present society, there is a great interest for
Internet-based marketing, namely the use of homepages for
marketing purposes. based on the number
- Law. Attorneys routinely tape legal
depositions and then later use the video and transcripts
to argue a case or impeach a witness. Annotations and
linking to videos is required in order to facilitate this
process. Hypervideo systems would facilitate finding the
appropriate parts of video and would also facilitate the
process creating hypervideo presentations.
